We developed a decision-analytic model to estimate the incremental cost-effectiveness ratio (ICER) of expanded reflex testing from a US payer perspective. Expanded reflex testing is defined as retesting tumor specimens from patients whose tumors are IHC0, IHC1+, or FISH-negative on their first test. In the base case, we assumed that 80% of patient tumors are initially IHC-tested and 20% are FISH-tested. Testing outcomes for IHC and FISH with and without retesting were based on published meta-analyses. The cost of tests and treatment and the long-term health outcomes were obtained from the literature.

In the base case, we estimated that 2.27% of women who received expanded reflex testing would be HER2-positive and receive trastuzumab treatment: the projected ICER was $36,721 per life year or $39,745 per quality-adjusted life year (QALY). This varied between $47,100 per QALY and $35,500 per QALY if we assumed that 1%-8% of patients retested were then HER2+, respectively. The results of deterministic and probabilistic sensitivity analysis were robust. This strategy would result in 4700 (2000-17,000) patients being eligible to receive trastuzumab treatment annually.

Retesting patients who are IHC0, IHC1+, or FISH-negative is projected to be a cost-effective clinical strategy. Cancer 2013. © 2013 American Cancer Society.

The median age of the patients was 54 years. At the time of diagnosis, 87% of patients had Ann Arbor stage IV disease, and 77% had bone marrow involvement. A Ki-67 level of > 30% was found in 11 of 27 patients (40%), and SOX11 (SRY [sex determining region Y)-box 11] expression was found to be positive in 17 of 18 patients (94%). Twenty-seven patients (69%) underwent induction therapy with high-dose cytarabine-containing chemotherapy. Rituximab was administered during stem cell collection at a dose of 1000 mg/m² on days +1 and +8 after ASCT.

The estimated 4-year overall survival and progression-free survival rates were 82% and 59%, respectively. Twelve patients experienced disease recurrence. Fifteen of 16 patients who were alive and in complete remission at 36 months remained so at a median follow-up of 69 months (range, 38 months-145 months). The only determinant of recurrence risk found was a Ki-67 level of > 30%. Seven of 11 patients with a Ki-67 level > 30% experienced disease recurrence within the first 3 years versus only 3 of 16 patients with a Ki-67 level ≤ 30% (P = .02). Patients who received high-dose cytarabine did not have a significantly different risk of developing disease recurrence compared with other patients (P = .7).

Administering ASCT with rituximab during stem cell collection and immediately after transplantation may induce a continuous long-term disease remission in patients with MCL with a Ki-67 level of ≤ 30%. Cancer 2013. © 2013 American Cancer Society.

Patients with previously treated but ErbB inhibitor-naive esophagogastric, biliary tract, urothelial tract, or gynecologic cancers (lung cancers were excluded) harboring EGFR/HER2 gene amplification or high polysomy were identified by fluorescence in situ hybridization (FISH). Tumors were also screened for EGFR mutations. The primary endpoint was the objective response rate; secondary endpoints included the clinical benefit rate, pharmacokinetics, and safety.

Of 385 prescreened patients, 38 had FISH-positive tumors (10 with EGFR amplification and 29 with HER2 amplification or high polysomy [1 tumor had EGFR/HER2 high polysomy]; none had EGFR-activating mutations), and 20 patients received treatment with afatinib 50 mg daily. The objective response rate was 5% (1 of 20 patients), and the best objective response included 1 complete response. Eight patients experienced stable disease. The most frequently reported adverse events were diarrhea, rash, and decreased appetite. The trial closed early because of slow recruitment.

Single-agent afatinib activity was limited, yet encouraging, in selected tumors that were screened prospectively for target activation. The implementation of a biomarker-driven approach using a low-frequency biomarker for patient selection across multiple tumor types can be challenging. Cancer 2013. © 2013 American Cancer Society.

Using 2004-2006 SEER Limited-Use Data, 51,982 early prostate cancer patients were identified (T1c, T2a, T2b, T2c, T2NOS; no metastases) who were most likely to benefit from definitive treatment (< 75 years old, Gleason score < 8, PSA ≤ 20). Definitive treatment included radical prostatectomy, daily external beam radiation for 5 to 8 weeks, brachytherapy, or combination external beam radiation/brachytherapy. Adjusted definitive treatment rates were calculated by rural–urban residence overall, and for different sociodemographic and cancer characteristics, and different states based on logistic regression analyses, using general estimating equation methods to account for clustering by county.

Adjusted definitive treatment rates were lower for rural (83.7%) than urban (87.1%) patients with early-stage prostate cancer (P ≤ .01). Rural men were more likely than urban men to receive nondefinitive surgical treatment and no initial treatment. The lowest definitive treatment rates were among rural subgroups: 70 to 74 years (73.9%), African Americans (75.6%), American Indians/Alaska Natives (77.8%), single/separated/divorced (76.8%), living in New Mexico (69.3%), and living in counties with persistent poverty (79.6%).

Between 2004 and 2006, this adjusted analysis found that men who were living in rural areas were less likely to receive definitive treatment for their early-stage prostate cancer than those living in urban areas. Certain rural patient groups with prostate cancer need particular attention to ensure their access to appropriate treatment. Rural providerss, rural health care systems, and cancer advocacy and support organizations should ensure resources are in place so that the most vulnerable rural groups (men between 60 and 74 years of age; African American men; men who are single, separated, or divorced; and men living in rural New Mexico) can make informed prostate cancer treatment choices based on their preferences.

Patients with progressive mCRPC and ≥3 bone lesions received ¹⁵³Sm-EDTMP (samarium-153 ethylene diamine tetramethylene phosphonate) at a dose of 1.0 mCi/kg every 9 weeks and docetaxel at a dose of 75 mg/m² every 3 weeks. In the absence of unacceptable toxicity, patients were allowed to continue additional cycles, defined by 9 weeks of treatment, until intolerance or biochemical/radiographic disease progression.

Of the 30 patients treated, approximately 50% were considered to be taxane-naive, 36.7% were taxane-refractory, and 13.3% had previously been exposed to taxanes but were not considered refractory. Patients received on average 2.5 cycles of treatment (6.5 doses of docetaxel and 2.5 doses of ¹⁵³Sm-EDTMP). Twelve patients (40%) demonstrated a decline in their prostate-specific antigen level of ≥50%. The median progression-free survival (biochemical or radiographic) was 7.0 months and the overall survival was 14.3 months. Nine patients (30%) did not recover platelet counts >100 K/mm³ after a median of 3 cycles to allow for additional treatment, with 4 patients experiencing prolonged thrombocytopenia. The most common reasons for trial discontinuation were progressive disease and hematologic toxicity.

The results of the current study indicate that ¹⁵³Sm-EDTMP can be safely combined with docetaxel at full doses on an ongoing basis in patients with mCRPC. Although thrombocytopenia limited therapy for some patients, preliminary efficacy supports the strategy of combining a radiopharmaceutical with chemotherapy, which is an appealing strategy given the anticipated availability of α emitters that can prolong survival.

In a controlled, randomized, prospective, double-blind, multicenter study, 111 patients with head and neck and esophageal cancer undergoing concurrent CRT received either an enteral standard nutrition (control group) or disease-specific enteral nutrition Supportan^®-containing EPA+DHA (experimental group) via percutaneous endoscopic gastrostomy. The primary endpoint was the change of body cell mass (BCM) following CRT at weeks 7 and 14 compared with the baseline value. Secondary endpoints were additional parameters of body composition, anthropometric parameters, and nutritional and functional status.

The primary endpoint of the study, improvement in BCM, reached borderline statistical significance. Following CRT, patients with experimental nutrition lost only 0.82 ± 0.64 kg of BCM compared with 2.82 ± 0.77 kg in the control group (P = .055). The objectively measured nutritional parameters, such as body weight and fat-free mass, showed a tendency toward improvement, but the differences were not significant. The subjective parameters, in particular the Kondrup score (P = .0165) and the subjective global assessment score (P = .0065) after follow-up improved significantly in the experimental group, compared with the control group. Both enteral regimens were safe and well tolerated.

Enteral nutrition with EPA and DHA may be advantageous in patients with head and neck or esophageal cancer by improving parameters of nutritional and functional status during CRT. Cancer 2013. © 2013 American Cancer Society.

Between November 2005 and June 2012, 301 patients with node-negative NPC were randomly assigned to receive primary plus prophylactic upper neck irradiation (UNI, 153 patients) or primary plus whole-neck irradiation (WNI, 148 patients). Patients in both groups received irradiation to the primary tumor and the upper neck nodal regions, and patients in the WNI group also received irradiation to the lower neck. The main endpoint of the study was to compare the lower neck control rate between the 2 groups.

With a median follow-up period of 39 months (range, 6-84 months), no patient in either group had a cervical node relapse. The overall survival at 3 years was 89.5% (95% confidence interval [CI] = 84.1%-95.0%) in the UNI group and 87.4% (95% CI = 81.4%-93.5%) in the WNI group (hazard ratio [HR] = 0.866, 95% CI = 0.41-1.82; P = .70). The 3-year relapse-free survival rate was 89.8% and 89.3% (95% CI = 84.2%-95.3% and 83.7%-94.8%, HR = 0.914, 95% CI = 0.42-2.00; P = .82), and the 3-year metastasis-free survival rate was 91.7% and 90.9% (95% CI = 87.0%-96.5% and 85.7%-96.1%) for the UNI and WNI groups, respectively (HR = 1.007, 95% CI = 0.44-2.32; P = .99).

Newly diagnosed HNC patients (2007-2010) at Princess Margaret Cancer Centre treated with curative intent were prospectively recruited. Patients completed self-reported baseline and follow-up questionnaires, assessing changes in social habits. Predictors of smoking cessation and time to quitting were evaluated using logistic regression and Cox proportional hazard models, respectively.

Of 295 HNC patients, 49% were current smokers at diagnosis, and 50% quit after diagnosis. These individuals were more likely to have smoked for fewer years (P = .0003), never used other forms of tobacco (P = .0003), and consumed less alcohol (P = .002). No cigarette exposure at home (OR, 7.44 [3.04-18.2]), no spousal smoking (OR, 4.25 [1.70-10.6]), and having fewer friends who smoke (OR, 2.32 [1.00-5.37]) were consistent predictors of smoking cessation after diagnosis. Having none of these exposures (OR, 13.8 [4.13-46.0]) and seeing a family physician (OR, 3.92 [1.38-11.2]) were independently associated with smoking cessation and time-to-quitting analyses. Most HNC patients (68%) quit within 6 months of diagnosis. Patients who were ex-smokers at diagnosis were older (P < .0001), more likely to be female (P = .0002), more likely to be married (P = .0004), more educated (P = .01), and had fewer pack-years of smoking (P < .0001).

Spousal smoking, peer smoking, smoke exposure at home, and seeing a family physician were strongly and consistently associated with smoking cessation and time to quitting after a HNC diagnosis. Cancer 2013. © 2013 American Cancer Society.

Women with a confirmed mismatch repair gene mutation for LS who were undergoing a prophylactic or therapeutic hysterectomy were eligible. Cases and controls were matched for EC and hyperplasia based preferentially on age and histology. Mutation status of phosphatidylinositol 3-kinase (PIK3CA); KRAS; AKT; LKB1; catenin (cadherin-associated protein), beta 1, 88kDa (CTNNB1); and phosphatase and tensin homolog (PTEN) protein loss was assessed.

Concurrent complex atypical hyperplasia (CAH) was found in EC in 11 cases of LS (39.3%) and 21 sporadic cases (46.6%). Loss of PTEN expression was common in both sporadic (69%) and LS-associated EC (86.2%). There was no significant difference noted with regard to the frequency of KRAS mutations in cases of sporadic EC (10.3%) compared with LS-associated EC (3.4%). AKT and LKB1 mutations were rarely observed. Mutations in PIK3CA and CTNNB1 occurred more frequently in cases of sporadic EC compared with LS-associated EC.

Hyperplasia, particularly CAH, is part of the preinvasive spectrum of disease in LS-associated EC, as indicated by the presence of complex hyperplasia and CAH in cases of LS. Although loss of PTEN is common in both LS and sporadic EC cases, there was a lack of additional mutations in LS-associated EC cases. This suggests that in the context of the mismatch repair defects in LS, fewer additional molecular changes are required to progress from preinvasive lesions to cancer.

Consecutive patients who were referred for first-time screening CTC from 2004 to 2011 at a single medical center were enrolled. Results at pathology were recorded for all patients who underwent polypectomy. Logistic regression was used to identify significant predictor variables for advanced neoplasia (any adenoma ≥10 mm or with villous component, high-grade dysplasia, or adenocarcinoma). Odds ratios (ORs) were used to express associations between the study variables (age, sex, BMI, and a positive family history of colorectal cancer) and advanced neoplasia.

In total, 7620 patients underwent CTC screening. Of these, 276 patients (3.6%; 95% confidence interval [CI], 3.2%-4.1%) ultimately were diagnosed with advanced neoplasia. At multivariate analysis, age (mean OR per 10-year increase, 1.8; 95% CI, 1.6-2.0) and being a man (OR, 1.7; 95% CI, 1.3-2.2) were independent predictors of advanced neoplasia, whereas BMI and a positive family history of colorectal cancer were not. The number needed to screen to detect 1 case of advanced neoplasia varied from 51 among women aged ≤55 years to 10 among men aged >65 years. The number of post-CTC colonoscopies needed to detect 1 case of advanced neoplasia varied from 2 to 4.

Age and sex were identified as important independent predictors of advanced neoplasia risk in individuals undergoing screening CTC, whereas BMI and a positive family history of colorectal cancer were not. These results have implications for appropriate patient selection. Cancer 2013. © 2013 American Cancer Society.

A total of 255 cases of PTRMS were identified from the patient data reported by the Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute from 1973 through 2009.

Among 173 patients aged ≥10 years, lymph node dissection was found to improve the 5-year overall survival (OS) rate from 64% to 86% (P < 0.01). Conversely, patients aged <10 years fared extremely well regardless of lymph node dissection status; the 5-year OS rate was 100% and 97%, respectively, for patients who did versus those who did not undergo lymph node dissection (P = .37). The yield of positive lymph nodes was approximately ≥ 20% when < 11 lymph nodes were removed. The incidence of lymph node involvement was also higher in older patients compared with younger patients (40% vs 8%). Radiotherapy improved the OS rate in patients with lymph node involvement (5-year OS rate: 90% with vs 36% without radiation; P < .0001).

Lymph node dissection is recommended in patients aged ≥10 years. Radiotherapy is beneficial in patients with lymph node-positive disease. Cancer 2013. © 2013 American Cancer Society.

Using the Surveillance, Epidemiology, and End Results program database, the authors calculated age-adjusted prostate cancer incidence rates among black and white men aged ≥45 years by race and county between 2000 and 2009 (N = 906,381 men). Similarly, county-level prostate cancer mortality rates were calculated from the National Vital Statistics System (N = 288,874). These data were linked with the average monthly solar ultraviolet (UV) radiation index by county and data regarding health, wellness, and demographics. Multivariable regression analysis was used to assess whether increases in the UV index (in deciles) moderated the association between black race and the incidence and mortality of prostate cancer.

Compared with counties in the lowest UV index decile, prostate cancer incidence rates for white and black men were lower in counties with a higher UV index (all Ps ≤ .0.051). Incidence rates were higher for black men versus white men, but the difference by race was less for counties in the fourth to fifth UV index deciles versus those in the first decile (Ps ≤ 0.02). Mortality rates also were found to decrease with increasing UV index for white men (Ps ≤ 0.003), but increase for black men, and an unexplained increase in racial differences in mortality rates was observed with an increasing UV index.

Racial disparities in the incidence of prostate cancer were larger in some areas with less sunshine. Additional research should confirm the findings of the current study and assess whether optimizing vitamin D levels among black men can reduce disparities.

The objectives were to describe sHER2 levels during treatment and at the time of recurrence in patients who were randomized to treatment arms A (standard chemotherapy), B (standard chemotherapy with sequential trastuzumab), and C (standard chemotherapy with concurrent trastuzumab). Baseline samples were available from 2318 patients, serial samples were available from 105 patients, and recurrence samples were available from 124 patients. The cutoff sHER2 value for the assay was 15 ng/mL. Statistical methods included repeated measures linear models, Wilcoxon rank-sum tests, and Cox regression models.

There were differences between groups in terms of age, menopausal status, and hormone receptor status. Within treatment arms A, B, and C, patients who had baseline sHER2 levels ≥15 ng/mL had worse disease-free survival than patients who had baseline sHER2 levels <15 ng/mL (arm A: hazard ratio, 1.81; P = .0014; arm B: hazard ratio, 2.08; P = .0015; arm C: hazard ratio, 1.96; P = .01). Among the 124 patients who experienced disease recurrence, sHER2 levels increased from baseline to the time of recurrence in arms A and B but remained unchanged in arm C. Patients who had recurrence sHER2 levels ≥15 ng/mL had a shorter survival after recurrence with a 3-year overall survival rate of 51% compared with 77% for those who had recurrence sHER2 levels <15 ng/mL (hazard ratio, 2.36; 95% confidence interval, 1.19-4.70; P = .01).

In patients with early stage, HER2-positive breast cancer, a high baseline sHER2 level was identified as a prognostic marker associated with shorter disease-free survival, and a high sHER2 level at recurrence was predictive of shorter survival. Cancer 2013 © 2013 American Cancer Society.

Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data, subjects were identified who had a diagnosis of high-grade, non–muscle-invasive disease in 1992 to 2002 and who were followed until 2007. Multivariate competing-risks regression analyses were then used to examine recurrence, progression, and bladder cancer–related mortality rates.

Of 7410 subjects, 2897 (39.1%) experienced a recurrence without progression, 2449 (33.0%) experienced disease progression, of whom 981 succumbed to bladder cancer. Using competing-risks regression analysis, the 10-year recurrence, progression, and bladder cancer–related mortality rates were found to be 74.3%, 33.3%, and 12.3%, respectively. Stage T1 was the only variable associated with a higher rate of recurrence. Women, black race, undifferentiated grade, and stage Tis and T1 were associated with a higher risk of progression and mortality. Advanced age (≥ 70) was associated with a higher risk of bladder cancer–related mortality.

Nearly three-fourths of patients diagnosed with high-risk bladder cancer will recur, progress, or die within 10 years of their diagnosis. Even though most patients do not die of bladder cancer, the vast majority endures the morbidity of recurrence and progression of their cancer. Increasing efforts should be made to offer patients intravesical therapy with the goal of minimizing the incidence of recurrences. Furthermore, the high recurrence rate seen during the first 2 years of diagnosis warrants an intense surveillance schedule. Cancer 2013. © 2013 American Cancer Society.

A previously developed survey was used to evaluate understanding of terms related to urinary, bowel, and sexual function. The survey was administered by trained evaluators at 2 safety net clinics that provide care for low-income, predominantly African American patients. Comprehension was assessed using semiqualitative methods coded by 2 independent investigators. Literacy and numeracy were also evaluated.

Among 109 patients who completed the study, only 5% understood the function of the prostate, and 15%, 29%, and 32% understood the terms “incontinence,” “urinary function,” and “bowel habits,” respectively. Lower levels of comprehension were observed for compound words, such as “vaginal intercourse” (58%), versus single words such as “intercourse” (95%), validating previous work. Median school level was 13 years, yet median literacy level was only ninth grade, and reading level was significantly correlated with comprehension. Only 30% of patients correctly calculated both a fraction and a percent.

Lack of comprehension of prostate health terminology is pronounced in this patient population and may be widespread. This lack of comprehension potentially limits the ability of patients to participate in informed decision-making. These results validate the findings of previous studies and support a continued need for refined methods of prostate cancer education. Cancer 2013. © 2013 American Cancer Society.

Patients were treated with temozolomide at a dose of 150 mg/m² per day on days 1 through 7 and days 15 through 21 in combination with everolimus daily in each 28-day cycle. In cohort 1, temozolomide was administered together with everolimus at 5 mg daily. Following demonstration of safety in this cohort, subsequent patients in cohort 2 were treated with temozolomide plus everolimus at 10 mg daily. The duration of temozolomide treatment was limited to 6 months. Patients were followed for toxicity, radiologic and biochemical response, and survival.

A total of 43 patients were enrolled, including 7 in cohort 1 and 36 in cohort 2. Treatment was associated with known toxicities of each drug; no synergistic toxicities were observed. Among 40 evaluable patients, 16 (40%) experienced a partial response. The median progression-free survival duration was 15.4 months. Median overall survival was not reached.

Temozolomide and everolimus can be safely administered together in patients with advanced pancreatic NET, and the combination is associated with encouraging antitumor activity. Future studies evaluating the efficacy of combination therapy compared to treatment with either agent alone are warranted. Cancer 2013. © 2013 American Cancer Society.

Our departmental database was queried for patients irradiated for OPC between 2001 and 2007. Analyzable patients were those with imaging data available for review to determine radiographic RPLN status. Demographic, clinical, and outcome data were retrieved and analyzed.

The cohort consisted of 981 patients. The median follow-up was 69 months. The base of the tongue (47%) and the tonsil (46%) were the most common primary sites. The majority of patients had stage T1 to T2 primary tumors (64%), and 94% had stage 3 to 4B disease. Intensity-modulated radiation therapy was used in 77% of patients, and systemic therapy was administered in 58% of patients. The incidence of radiographic RPLN involvement was 10% and was highest for the pharyngeal wall (23%) and lowest for the base of the tongue (6%). RPLN adenopathy correlated with several patient and tumor factors. RPLN involvement was associated with poorer 5-year outcomes on univariate analysis (P<.001 for all) for local control (79% vs 92%), nodal control (80% vs 93%), recurrence-free survival (51% vs 81%), distant metastases-free survival (66% vs 89%), and overall survival (52% vs 82%) and maintained significance on multivariate analysis for local control (P = .023), recurrence-free survival (P = .001), distant metastases-free survival (P = .003), and overall survival (P = .001).

In this cohort of nearly 1000 patients with radiographic RPLN adenopathy in OPC, RPLN involvement was observed in 10% of patients and indicates a negative influence on disease recurrence, distant relapse, and survival. Cancer 2013. © 2013 American Cancer Society.

Individual data were pooled from 399 patients who were enrolled on 8 phase 2 and 3 trials evaluating cisplatin-based, first-line chemotherapy in patients with metastatic urothelial carcinoma. Variables selected for inclusion in the model were combined in a Cox proportional hazards model to produce a points-based nomogram with which to predict the median, 1-year, 2-year, and 5-year survival. The nomogram was validated externally using data from a randomized trial of the combination of methotrexate, vinblastine, doxorubicin plus cisplatin versus docetaxel plus cisplatin.

The median survival of the development cohort was 13.8 months (95% confidence interval, 12.1 months-16.0 months); 68.2% of the patients had died at the time of last follow-up. On multivariable analysis, the number of visceral metastatic sites, Eastern Cooperative Oncology Group performance status, and leukocyte count were each found to be associated with overall survival (P < .05), whereas the site of the primary tumor and the presence of lymph node metastases were not. All 5 variables were included in the nomogram. When subjected to internal validation, the nomogram achieved a bootstrap-corrected concordance index of 0.626. When applied to the external validation cohort, the nomogram achieved a concordance index of 0.634. Calibration plots suggested that the nomogram was well calibrated for all predictions.

Based on routinely measured pretreatment variables, a nomogram was constructed that predicts survival in patients with unresectable and/or metastatic urothelial cancer who are treated with cisplatin-based chemotherapy. This model may be useful in patient counseling and clinical trial design. Cancer 2013. © 2013 American Cancer Society.

A Markov model was created to compare the cost-effectiveness of SBRT with WR and lobectomy for MO and CO patients, respectively. Disease, treatment, and toxicity data were extracted from the literature and varied in sensitivity analyses. A payer (Medicare) perspective was used.

In the base case, SBRT (MO cohort), SBRT (CO cohort), WR, and lobectomy were associated with mean cost and quality-adjusted life expectancies of $42,094/8.03, $40,107/8.21, $51,487/7.93, and $49,093/8.89, respectively. In MO patients, SBRT was the dominant and thus cost-effective strategy. This result was confirmed in most deterministic sensitivity analyses as well as probabilistic sensitivity analysis, in which SBRT was most likely cost-effective up to a willingness-to-pay of more than $500,000/quality-adjusted life year. For CO patients, lobectomy was the cost-effective treatment option in the base case (incremental cost-effectiveness ratio of $13,216/quality-adjusted life year) and in nearly every sensitivity analysis.

SBRT was nearly always the most cost-effective treatment strategy for MO patients with stage I NSCLC. In contrast, for patients with CO disease, lobectomy was the most cost-effective option. Cancer 2013. © 2013 American Cancer Society.

Data was pooled from 7 phase 2 and 3 trials evaluating cisplatin-based chemotherapy in metastatic UC. An independent cohort of patients enrolled on a phase 3 trial was used for external validation. Landmark analyses for progression at 6 and 9 months after treatment initiation were performed to minimize lead-time bias. A proportional hazards model was used to assess the utility of PFS for predicting OS.

A total of 364 patients were included in the initial cohort. The median PFS was 8.21 months (95% confidence interval = 7.43, 8.39) and the median OS was 13.50 months (95% confidence interval = 11.80, 15.67). In the landmark analysis, the median OS for patients who progressed at 6 months was 3.87 months compared with 15.06 months for those patients who did not progress (P < .0001) and the median OS for patients who progressed at 9 months was 5.65 months compared with 21.39 months for those patients who did not progress (P < .0001). A Fleischer model demonstrated a statistically significant dependent correlation between PFS and OS. The findings were externally validated in an independent cohort.

PFS at 6 and 9 months predicted OS in this analysis of patients with metastatic UC treated with first-line cisplatin-based chemotherapy and could potentially serve as endpoints in (randomized) phase 2 trials to screen the activity of novel regimens. Cancer 2013. © 2013 American Cancer Society.

Data was obtained from the 5088 PCPT participants and was used to construct the PCPT Risk Calculator. The relationship between PSA and the risk of a positive biopsy was modeled by using locally-weighted regression (lowess), an empirical estimate of actual risks observed which does not depend on a statistical model. Risks were estimated with and without the 3514 end-of-study biopsies.

For PSA levels above biopsy thresholds (∼4 ng/mL), the PCPT Risk Calculator greatly overestimated actual empirical risks (eg, 44% versus 26% at 5 ng/mL). The change in risk with increasing PSA was less among for-cause biopsies compared with the end-of-study biopsies (P = .001). Risk of high-grade disease was overestimated at PSA level of ≥ 6 ng/mL.

The PCPT Risk Calculator overestimates risks for PSAs close to and above typical biopsy thresholds. Separating for-cause biopsies from end-of-study biopsies and using empirical rather than model-based risks reduces overall risk estimates and replicates prior findings that, in men who have been screened with PSA, there is no rapid increase in prostate cancer risk with higher PSA. Revision of the PCPT Risk Calculator should be considered. Cancer 2013. © 2013 American Cancer Society.

This quasiexperimental evaluation compared low-income patients at average risk for CRC (n = 809) from 4 intervention clinics and 9 comparison clinics. We abstracted medical chart data on patient demographics, CRC history and risk factors, and CRC screening referrals and examinations. Outcomes of interest were colonoscopy referral and examination during the study period and being compliant with recommended screening guidelines at the end of the study period. We conducted multilevel logistic analyses to evaluate the program's effectiveness.

Patients at intervention clinics were significantly more likely than patients at comparison clinics to undergo colonoscopy screening (35% versus 7%, odds ratio = 7.9, P < .01) and be guideline-compliant on at least one CRC screening test (43% versus 11%, odds ratio = 5.9, P < .001).

Patient navigation, delivered through the Community Cancer Screening Program, can be an effective approach to ensure that lifesaving, preventive health screenings are provided to low-income adults in a rural setting. Cancer 2013. © 2013 American Cancer Society.

A cohort of men with CRPC with and without metastases (M) treated with secondary hormonal therapy (2eHT) and/or chemotherapy (CT) was identified from the authors' institutional database. Associations of patient and disease characteristics at diagnosis, at androgen-deprivation therapy (ADT) initiation, at CRPC index date, and survival were evaluated. CRPC index date was defined as the start date of either 2eHT or CT, whichever came first.

In the cohort of 622 men, 434 men (70%) had M-positive disease; 552 men (89%) received 2eHT and 70 men (11%) received CT as their initial CRPC treatment. There were 410 deaths (66%) at the time of analysis. Median overall survival (OS) was 35 months (quartile 1, quartile 3: 21 months, 61 months). In multivariate analyses, higher biopsy Gleason score, the presence of M at ADT initiation, shorter time from ADT start to CRPC, higher prostate-specific antigen and poorer Eastern Cooperative Oncology Group performance status at CRPC and M at CRPC were predictive of shorter OS. Interestingly, whereas some men with biopsy Gleason scores of 6 died of their disease (N = 42), they had a longer OS after CRPC compared with those with a Gleason score ≥ 7.

This large retrospective study of patients with CRPC in a tertiary cancer center shows that biopsy Gleason score of 6 is associated with a less aggressive CRPC course, and the impact that M at ADT initiation and CRPC have on outcome is quantified. Cancer 2013. © 2013 American Cancer Society.

All patients with esophageal adenocarcinoma in the SEER database from 2004 to 2009 were included. Univariate and multivariate analyses examining the relationship of signet ring cell histology with overall survival were performed in all patients, as well as those undergoing surgical resection.

A total of 596 of 11,825 (5%) study patients had signet ring cell histology. Patients with signet ring cell histology were similar in age, race, and sex distribution, but had a higher grade (P <  .001) and higher stage (P <  .001) at diagnosis. In both the all-patient group as well as those undergoing surgical resection, univariate analyses showed a worse survival in patients with signet ring cell esophageal cancer (hazard ratio [HR] = 1.24; 95% confidence interval [CI] = 1.13-1.36 and HR = 1.57; 95% CI = 1.29-1.93, respectively). In multivariate analyses adjusting for covariates, patients with signet ring cell cancer had a worse prognosis than those without (HR = 1.18; 95% CI = 1.07-1.30). In surgically resected patients, this remained a trend, but did not reach statistical significance (HR = 1.16; 95% CI = 0.94-1.42).

This large study of esophageal adenocarcinoma confirms the clinical impression that signet ring cell variant of adenocarcinoma is associated with an advanced stage at presentation and a worse prognosis independent of stage of presentation. Cancer 2013. © 2013 American Cancer Society.

In total, 109 patients who underwent resection for GAC between January 2000 and June 2011 had tissue available for analysis. The primary objective was to assess for the differential expression of ERCC1 and TS using immunohistochemistry. The secondary objective was to assess for the association between OS and the expression of ERCC1 and TS.

The median follow-up was 21.2 months, and the median OS was 28.8 months. Resected GAC exhibited differential expression of ERCC1 (high expression, 23%; n = 25) and TS (high expression, 43%; n = 47). ERCC1 and TS expression were not associated with OS. In a subset analysis of patients who received chemotherapy (n = 73), high ERCC1 expression was associated with decreased OS (16.7 months vs 53.8 months; P = 0.03). After controlling for known adverse pathologic features, high ERCC1 expression persisted as a negative prognostic factor in multivariate Cox regression analysis (hazard ratio, 2.5; 95% confidence interval, 1.03-6.0; P = .04). Conversely, in patients who underwent resection only (n = 35), high ERCC1 expression demonstrated a trend toward improved OS (40.4 months vs 12.7 months; P = .10); a positive prognostic influence also was present on multivariate analysis (hazard ratio, 0.20; 95% confidence interval, 0.04-0.86; P = .03).

Resected GAC exhibited differential expression of TS and ERCC1. Among all patients, ERCC1 and TS expression levels were not associated with OS. High ERCC1 tumor expression was associated with decreased OS in the patients who received chemotherapy but was associated with increased OS in those who underwent surgery alone. ERCC1 expression had prognostic value in resected gastric cancer, and further investigation is warranted. Cancer 2013. © 2013 American Cancer Society.

Eligibility included confirmation of adenocarcinoma, resectable or borderline resectable disease, a performance status ≤2, and adequate organ function. Treatment consisted of two 28-day cycles of gemcitabine (1 g/m² over 30 minutes on days 1, 8, and 15) and oxaliplatin (85 mg/m² on days 1 and 15) with RT during cycle 1 (30 Gray [Gy] in 2-Gy fractions). Patients were evaluated for surgery after cycle 2. Patients who underwent resection received 2 cycles of adjuvant chemotherapy.

Sixty-eight evaluable patients received treatment at 4 centers. By central radiology review, 23 patients had resectable disease, 39 patients had borderline resectable disease, and 6 patients had unresectable disease. Sixty-six patients (97%) completed cycle 1 with RT, and 61 patients (90%) completed cycle 2. Grade ≥3 adverse events during preoperative therapy included neutropenia (32%), thrombocytopenia (25%), and biliary obstruction/cholangitis (14%). Forty-three patients underwent resection (63%), and complete (R0) resection was achieved in 36 of those 43 patients (84%). The median overall survival was 18.2 months (95% confidence interval, 13–26.9 months) for all patients, 27.1 months (95% confidence interval, 21.2–47.1 months) for those who underwent resection, and 10.9 months (95% confidence interval, 6.1–12.6 months) for those who did not undergo resection. A decrease in CA 19-9 level after neoadjuvant therapy was associated with R0 resection (P = .02), which resulted in a median survival of 34.6 months (95% confidence interval, 20.3–47.1 months). Fourteen patients (21%) are alive and disease free at a median follow-up of 31.4 months (range, 24–47.6 months).

Preoperative therapy with full-dose gemcitabine, oxaliplatin, and RT was feasible and resulted in a high percentage of R0 resections. The current results are particularly encouraging, because the majority of patients had borderline resectable disease. Cancer 2013. © 2013 American Cancer Society.

Survival statistics were extracted from the Surveillance, Epidemiology, and End Results (SEER) database for patients diagnosed with mCRC between 1988 and 2008. Demographic variables collected included age, race, and tumor grade. Survival was analyzed using the Kaplan-Meier method and extended Cox proportional hazard model as appropriate.

The study population consisted of 42,347 patients diagnosed with mCRC between 1988 and 2008 (52% women; mean age, 67 years). The 1- and 2-year estimated OS rates were 44% and 22%, respectively. Prognostic variables included race, sex, age, tumor location, and year of diagnosis. Median OS improved from 8 months to 14 months between 1988 and 2008. Significant improvements in OS were seen for all disease sites, but especially for descending colon cancers. Whereas the median OS increased by 13 months in patients ≤50 years of age and by 7 months in patients 51-70 years of age, the median OS of patients >70 years of age increased by only 1 month between 1988 and 2008.

There has been a continuous improvement in OS of patients diagnosed with mCRC between 1988 and 2008, especially for left-sided tumors. Little improvement has been seen in patients over 70 years of age. Cancer 2013. © 2013 American Cancer Society.

Tissue from 80 patients was collected from a prospectively maintained database of patients with PAC who underwent pancreaticoduodenectomy between January 2000 and October 2008. Immunohistochemistry analysis was performed and scored using an established scoring system. Kaplan-Meier survival curves were generated for recurrence-free survival (RFS) and overall survival (OS) for all patients and for patients receiving adjuvant chemotherapy. MLKL scores were correlated with RFS and OS using univariate and multivariate Cox regression analyses incorporating clinically relevant covariates.

The median age of the patients was 63 years and 53% were men. Low MLKL expression was associated with decreased OS (6 months vs 17 months; P = .006). In the subset of 59 patients who received adjuvant chemotherapy, low MLKL expression was associated with decreased RFS (5 months vs 15 months; P = .006) and decreased OS (6 months vs 19 months; P < .0001). On multivariate analysis, low MLKL expression was associated with poor OS in all patients (hazards ratio, 4.6 [95% confidence interval, 1.6-13.8]; P = .006) and in patients receiving adjuvant chemotherapy (hazards ratio, 8.1 [95% confidence interval, 2.2-29.2]; P = .002).

Low expression of MLKL is associated with decreased OS in patients with resected PAC and decreased RFS and OS in the subset of patients with resected PAC who receive adjuvant chemotherapy. The use of this biomarker in patients with PAC may provide important prognostic information. Cancer 2013. © 2013 American Cancer Society.

Information on dates of invitation, attendance, breast cancer diagnosis, emigration, death, and cause of death was linked by using unique 11-digit personal identification numbers assigned all inhabitants of Norway at birth or immigration. In total, 699,628 women ages 50 to 69 years without prior a diagnosis of breast cancer were invited to the program from 1996 to 2009 and were followed for breast cancer through 2009 and death through 2010. Incidence-based breast cancer mortality rate ratios (MRRs) were compared between the screened and nonscreened cohorts using a Poisson regression model. The MRRs were adjusted for calendar period, attained age, years since inclusion in the cohorts, and self-selection bias.

The crude breast cancer mortality rate was 20.7 per 100,000 women-years for the screened cohort compared with 39.7 per 100,000 women-years for the nonscreened cohort, resulting in an MRR of 0.52 (95% confidence interval, 0.47-0.59). The mortality reduction associated with attendance in the program was 43% (MRR, 0.57; 95% confidence interval, 0.51-0.64) after adjusting for calendar period, attained age, years after inclusion in the cohort, and self-selection bias.

After 15 years of follow-up, a 43% reduction in mortality was observed among women who attended the national mammographic screening program in Norway. Cancer 2013. © 2013 American Cancer Society.

Data on 2215 patients (1963 with clear-cell RCC [ccRCC] and 252 with nccRCC) treated with first-line VEGF- and mTOR-targeted therapies were collected from the IMDC. Time to treatment failure (TTF) and overall survival (OS) were compared in groups with favorable, intermediate, and poor prognoses according to IMDC prognostic criteria

The median OS of the entire cohort was 20.9 months. nccRCC patients were younger (P < .0001) and more often presented with low hemoglobin (P = .014) and elevated neutrophils (P = .0001), but otherwise had clinicopathological features similar to those of ccRCC patients. OS (12.8 vs 22.3 months; P < .0001) and TTF (4.2 vs 7.8 months; P < .0001) were worse in nccRCC patients compared with ccRCC patients. The hazard ratio for death and TTF when adjusted for the prognostic factors was 1.41 (95% CI, 1.19-1.67; P < .0001) and 1.54 (95% CI, 1.33-1.79; P < .0001), respectively. The IMDC prognostic model reliably discriminated 3 risk groups to predict OS and TTF in nccRCC; the median OS of the favorable, intermediate, and poor prognosis groups was 31.4, 16.1, and 5.1 months, respectively (P < .0001), and the median TTF was 9.6, 4.9, and 2.1 months, respectively (P < .0001).

Although targeted agents have significantly improved the outcome of patients with nccRCC, for the majority survival is still inferior compared with patients with ccRCC. The IMDC prognostic model reliably predicts OS and TTF in nccRCC and ccRCC patients. Cancer 2013. © 2013 American Cancer Society.

To study the biology of MBM, histopathologic analysis of tumor blocks from patients' craniotomy samples and whole-genome expression profiling (WGEP) with confirmatory immunohistochemistry were performed.

High mononuclear infiltrate and low intratumoral hemorrhage were associated with prolonged overall survival (OS). Pathway analysis of WGEP data from 29 such craniotomy tumor blocks demonstrated that several immune-related BioCarta gene sets were associated with prolonged OS. WGEP analysis of MBM in comparison with same-patient EcM and PrM showed that MBM and EcM were similar, but both differ significantly from PrM. Immunohistochemical analysis revealed that peritumoral CD3⁺ and CD8⁺ cells were associated with prolonged OS.

MBMs are more similar to EcM compared with PrM. Immune infiltrate is a favorable prognostic factor for MBM. Cancer 2013. © 2013 American Cancer Society.

The authors examined the association between MATH and clinical, pathologic, and overall survival data for 74 patients with HNSCC for whom exome sequencing was completed.

High MATH (a MATH value above the median) was found to be significantly associated with shorter overall survival (hazards ratio, 2.5; 95% confidence interval, 1.3-4.8). MATH was similarly found to be associated with adverse outcomes in clinically high-risk patients with an advanced stage of disease, and in those with tumors classified as high risk on the basis of validated biomarkers including those that were negative for human papillomavirus or having disruptive tumor protein p53 mutations. In patients who received chemotherapy, the hazards ratio for high MATH was 4.1 (95% confidence interval, 1.6-10.2).

This novel measure of tumor genetic heterogeneity is significantly associated with tumor progression and adverse treatment outcomes, thereby supporting the hypothesis that higher genetic heterogeneity portends a worse clinical outcome in patients with HNSCC. The prognostic value of some known biomarkers may be the result of their association with high genetic heterogeneity. MATH provides a useful measure of that heterogeneity to be prospectively validated as NGS data from homogeneously treated patient cohorts become available Cancer 2013. © 2013 American Cancer Society.

The authors conducted a retrospective, 1:1 matching case-control study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare–linked database to examine use of PCP services and their association with breast cancer mortality and incidence. SEER cases representing the 3 outcomes of interest (breast cancer mortality, all-cause mortality among women diagnosed with breast cancer, and breast cancer incidence) were matched to unaffected controls from the 5% Medicare random sample. Conditional logistic regression was used to examine associations between physician visits and breast cancer outcomes while controlling for other covariates.

Women who had 2 or more PCP visits during the 24-month assessment interval had lower odds of breast cancer mortality, all-cause mortality, and late-stage breast cancer diagnosis compared with women who had no PCP visits or 1 PCP visit while adjusting for other covariates, including mammography and non-PCP visits. Women who had 5 to 10 PCP visits had 0.69 times the odds of breast cancer mortality (95% confidence interval, 0.63-0.75), 0.83 times the odds of death from any cause having been diagnosed with breast cancer (95% confidence interval, 0.79-0.87), and 0.67 times the odds of a late-stage breast cancer diagnosis (95% confidence interval, 0.61-0.73) compared with those who had no PCP visits or 1 PCP visit.

The current findings suggest that PCPs play an important role in reducing breast cancer mortality among the Medicare population. Further research is needed to better understand the impact of primary care on breast cancer and other cancers that are amendable to prevention or early detection.

Patients with PNSSCC reported to the Surveillance, Epidemiology, and End Results (SEER) Program from 1973 through 2009 were categorized by sex, age, year of diagnosis, primary site, stage, and treatment. The incidence and survival were then compared across different demographic and disease-related categories by calculating rate ratios (RRs) and mortality hazard ratios along with the corresponding 95% confidence intervals (CIs).

In total, 2553 patients with PNSSCC were identified. While incidence of PNSSCC showed a gradual decline, survival remained largely unchanged. The proportion of patients with advanced disease decreased from 14.7% during the period from 1983 to 1992 to 12.4% during 1993-2002 and to 9.5% during 2003-2009. Compared with whites, incidence was higher among African Americans (RR 1.63; 95% CI, 1.39, 1.90) and among all other racial groups (RR, 1.78; 95% CI: 1.53-2.07). After adjusting for age, sex, disease stage, tumor site, and treatment, mortality among African American patients also was increased (hazard ratio, 1.22; 95% CI, 1.04-1.43). Among patients with localized disease, the relation between race and mortality was no longer evident once the results were controlled for tumor classification.

The current findings point to racial disparities in the incidence of PNSSCC and, to a lesser extent, in the outcome of patients with PNSSCC. Although there has been a decline in the proportion of patients presenting with advanced PNSSCC, the overall survival remained stable over time. Cancer 2013. © 2013 American Cancer Society.

Cetuximab was administered on days 1, 8, 15, 29, 36, 43, and 50 (400 mg/m² initial dose, then 250 mg/m²/week) concurrent with total dose radiation of 55 to 59 Gy, both starting on day 1. Escalating doses of 5-FU (96-hour infusion) and CP (2-hour infusion), both on days 1 and 29, were administered according to the following design: starting dose level (0) 5-FU/CP = 800/60 mg/m²/day and up to dose level (+2) 5-FU/CP = 1000/80 mg/m²/day.

Dose-limiting toxicity (DLT) events (uncontrolled diarrhea or febrile neutropenia) occurred in 3 of 14 assessable patients receiving escalated dose of 5-FU/CP, with 1 in dose level (0) and 2 in dose level (+2). The RP2D was 5-FU/CP = 800/80 mg/m²/day. Because of unexpected non-DLT treatment-related grade 3 (G3) adverse events (AEs) such as thrombosis/embolism, syncope, and infection occurring in ≥ 20% of patients, a safety expansion cohort with an additional 9 patients was investigated with the RP2D. The most frequent G3/G4 AEs evaluated in 23 patients were radiation dermatitis (12 patients), diarrhea (10 patients), thrombosis/embolism (6 patients), and infection (5 patients). The study was closed due to these severe AEs, although no G5 AEs occurred. Twenty of 21 patients (95%) achieved pathological complete response at primary tumor. With a median follow-up of 43.4 months, the 3-year locoregional control rate was 64.2%.

Cetuximab could not be integrated with chemoradiotherapy-cisplatin–based therapy due to the high toxicity rate. However, efficacy is encouraging and further investigation of an epidermal growth factor receptor–targeted agent (other than cetuximab) concurrent with chemoradiation should be pursued.

This study investigated the clinical relevance of 380 genes whose expression has been shown to affect the response to chemotherapy, mostly through in vitro studies, in 11 paired samples obtained at AML diagnosis and at relapse. The expression profiling of these 380 genes was performed using TaqMan-based quantitative reverse-transcription polymerase chain reaction. Patients had a median age of 58 years at diagnosis, a median duration of complete remission of 284.5 days, and a median overall survival of 563 days. Cytogenetic abnormalities were detected at diagnosis in 4 patients, whereas 5 displayed a normal karyotype and 2 were not investigated.

Hierarchical clustering shows that samples taken at diagnosis and relapse clustered in pairs for 6 patients of the 11 studied, suggesting recurrence of the same leukemic blast, whereas for the other 5 patients, the data indicate their relapse blasts arose from different origins. A patient-by-patient analysis of the paired samples led to the striking observation that each had a unique gene signature representing different mechanisms of resistance.

The data underline the need for personalized molecular analysis to tailor treatment for patients with AML. Cancer 2013. © 2013 American Cancer Society.

A matched cohort study was performed using the Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset. Individuals treated with PN or RN for localized renal cell carcinoma (RCC) measuring ≤4 cm were compared with 2 control groups (non–muscle-invasive bladder cancer (BCC) and noncancer controls (NCC). Using a greedy algorithm, RCC groups were matched with controls by demographics and comorbidities. OS for surgical groups and controls were compared. The cause of death was evaluated for cancer groups when differences in OS were noted.

Patients undergoing PN and RN were matched with controls. All cancer groups had >95% 10-year cancer-specific survival (CSS). Median OS was similar between RN (9.05 years) and BCC (8.67 years; P = .067) and NCC (8.77 years; P = .49). Median OS was improved for PN (10.45 years) compared with BCC (8.75 years; P<.001) and NCC controls (8.76 years; P<.001). A multivariate Cox hazards model demonstrated that PN improved OS compared with NCC (hazard ratio, 1.257; P<.001) and BCC (hazard ratio, 1.364; P<.001).

RN patients had similar OS compared with controls, suggesting that this treatment modality does not compromise survival. Patients undergoing PN had improved OS compared with controls, suggesting possible selection bias. The apparent survival advantage conferred by PN in SEER-Medicare case series is likely the result of selection bias involving unmeasured confounders. Cancer 2013. © 2013 American Cancer Society.

The medical records of consecutive, new patient consultations between January and March 2007 were reviewed. Patient medical decisions were classified as those with (Group 1) or without (Group 2) available, relevant level I evidence (phase 3 RCT) supporting recommended treatments. Group 1 medical decisions were further divided into 3 groups based on the extent of fulfilling eligibility criteria for each RCT: Group 1A included decisions that fulfilled all eligibility criteria; Group 1B, decisions that did not fulfill at least 1 minor eligibility criteria; or Group 1C, decisions that did not fulfill at least 1 major eligibility criteria. Patient and clinical characteristics were tested for correlations with the availability of evidence.

Of the 393 evaluable patients, malignancies of the breast (30%), head and neck (18%), and genitourinary system (14%) were the most common presenting primary disease sites. Forty-seven percent of all medical decisions (n = 451) were made without available (36%) or applicable (11%) randomized evidence to inform clinical decision making. Primary tumor diagnosis was significantly associated with the availability of evidence (P < .0001).

A significant proportion of medical decisions in an academic radiation oncology clinic were made without available or applicable level I evidence, underscoring the limitations of relying solely on RCTs for the development of evidence-based health care. Cancer 2013. © 2013 American Cancer Society.

We conducted a systematic review using OVID as the primary source of reports included. Based on 304 peer-reviewed publications, diversity in the inclusion and reporting of study participants during a decade of cancer treatment and prevention trials (2001-2010) is summarized. Recommendations are made for improvements in the science and reporting of cancer clinical trials.

Of the 277 treatment trials and 27 prevention trials included in this report, more than 80% of participants were white and 59.8% were male. In the recent decade, race and sex are rarely used as selection criteria unless the trial is focused on a sex-specific cancer.

Women and racial/ethnic minorities remain severely underrepresented in cancer clinical trials, thus limiting the generalizability of cancer clinical research. Cancer 2013. © 2013 American Cancer Society.

In total, 186 patients with PBTs were accrued at various points in the illness trajectory. Data-collection tools included an investigator-completed clinician checklist, a patient-completed demographic data sheet, the Mishel Uncertainty in Illness Scale-Brain Tumor Form (MUIS-BT), the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT), and the Profile of Mood States-Short Form (POMS-SF). Structural equation modeling was used to explore correlations among variables.

Participants were primarily white (80%) men (53%) with a variety of brain tumors. They ranged in age from 19 to 80 years (mean ± standard deviation, 44.2 ± 12.6 years). Lower functional status and earlier point in the illness trajectory were associated with greater uncertainty (P < .01 for both). Uncertainty (P < .05), except in the model of “confusion,” and the 5 negative mood states measured by the POMS-SF were directly associated with symptom severity perceived by patients (P < .01 for all). The impact of uncertainty on perceived symptom severity also was mediated significantly by mood states.

The results from the study clearly demonstrated distinct pathways for the relations between uncertainty-mood states-symptom severity for patients with PBTs. Uncertainty in patients with PBTs is higher for those who have a poor performance status and directly impacts negative mood states, which mediate patient-perceived symptom severity. This conceptual model suggests that interventions designed to reduce uncertainty or that target mood states may help lessen patients' perception of symptom severity, which, in turn, may result in better treatment outcomes and quality of life.

Patients with stage IIIB/IV NSCLC who progressed after first-line or second-line treatment were randomized to receive either pemetrexed or erlotinib. In total, 21.7% of patients in the pemetrexed arm and 23.5% of patients in the erlotinib arm had squamous cell histology, and treatment was third line in 39.2% and 46.4% of patients, respectively. The primary study endpoint was time to tumor progression (TTP). Epidermal growth factor receptor/v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (EGFR/KRAS) mutation status also was investigated.

There was no difference in terms of the TTP (P = .195), the objective response rate (P = .469), or overall survival (P = .986) between the 2 treatment arms. In patients who had squamous cell histology, erlotinib resulted in a superior TTP compared with pemetrexed (4.1 months vs 2.5 months, respectively; P = .006). The incidence of grade 3 and 4 neutropenia, thrombocytopenia, and asthenia was significantly higher in the pemetrexed arm, whereas the incidence of grade 3 and 4 skin rash was higher in the erlotinib arm.

Both pemetrexed and erlotinib had comparable efficacy in pre-treated patients with metastatic NSCLC, and the current results indicated that genotyping of tumor cells may have an important effect on treatment efficacy. Cancer 2013; © 2013 American Cancer Society.

This analysis included 832 women aged 18 to 39 years reported to a surveillance registry in Connecticut during 2008 to 2010. Diagnostic specimens were obtained for HPV DNA testing. Individual measures were obtained from surveillance reports, medical records, and patient interviews. Cases were geocoded to census tracts and linked to area-based measures of race, ethnicity, and poverty. Statistical analysis included use of generalized estimating equations.

Overall, 44.8% of women had HPV 16/18. In a multivariate model controlled for confounding by age and diagnosis grade, black race (adjusted prevalence ratio [aPR] = 0.54, 95% confidence interval [CI] = 0.34-0.88), Hispanic ethnicity (aPR = 0.59, 95% CI = 0.40-0.88), and higher area-based poverty (aPR = 0.59, 95% CI = 0.40-0.87) were associated with a lower likelihood of HPV 16/18 positivity. Black and Hispanic women were less likely to have HPV 16/18 than white women across all levels of area-based measures.

Black race, Hispanic ethnicity, and higher area-based poverty are salient predictors of lower HPV 16/18 positivity among women with high-grade cervical lesions. These data suggest that HPV vaccines might have lower impact among black and Hispanic women and those living in high poverty areas. These findings have implications for vaccine impact monitoring, vaccination programs, and new vaccine development. Cancer 2013; © 2013 American Cancer Society.

Primary stage III colon carcinomas were analyzed for BRAF^V600E mutations in exon 15, and 50 BRAF^V600E mutation carriers and 25 wild-type tumors were selected for analysis of BRAF proteins by immunohistochemistry (IHC). IHC was performed in archival tissue specimens using a pan-BRAF antibody and a mutation-specific antibody against BRAF^V600E proteins. Staining was scored by 2 pathologists who were blinded to clinical and mutation data.

Using a pan-BRAF antibody, total BRAF protein expression was observed in the tumor cell cytoplasm in 74 of 75 colon carcinomas. A mutation-specific antibody identified diffuse cytoplasmic staining of mutant BRAF^V600E proteins in 49 of 74 cancers. Analysis using a polymerase chain reaction-based assay revealed that all 49 of these cancers carried BRAF^V600E mutations. In contrast, BRAF^V600E staining was absent in all 25 tumors that carried wild-type copies of BRAF.

A BRAF mutation-specific (V600E) antibody detected tumors with BRAF^V600E mutations and exhibited complete concordance with a DNA-based method. These results support the use of IHC as a simplified strategy to screen colorectal cancers for BRAF^V600E mutations in clinical practice. Cancer 2013; © 2013 American Cancer Society.

Patients with refractory-relapsed ALL received treatment with inotuzumab. The first 49 patients received single-dose, intravenous inotuzumab at doses of 1.3 to 1.8 mg/m2 every 3 to 4 weeks. In the next 41 patients, the schedule was modified to inotuzumab weekly at a dose of 0.8 mg/m2 on day 1 and at a dose of 0.5 mg/m2 on days 8 and 15, every 3 to 4 weeks, based on higher in vitro efficacy with more frequent exposure.

Ninety patients were treated; 68% were in salvage 2 or beyond. Overall, 17 patients (19%) achieved a complete response (CR), 27 (30%) had a CR with no platelet recovery (CRp), and 8 (9%) had a bone marrow CR (no recovery of counts), for an overall response rate of 58%. Response rates were similar for single-dose and weekly dose inotuzumab (57% vs 59%, respectively). The median survival was 6.2 months overall, 5.0 months with the single-dose schedule, and 7.3 months with the weekly dose schedule. The median survival was 9.2 months for patients in salvage 1 (37% at 1 year), 4.3 months for patients in salvage 2, and 6.6 months for patients in salvage 3 or later. The median remission duration was 7 months. Reversible bilirubin elevation, fever, and hypotension were observed less frequently on the weekly dose. In total, 36 of 90 patients (40%) underwent allogeneic stem cell transplantation. Veno-occlusive disease was noted in 6 of 36 patients after stem cell transplantation (17%), was less frequent after the weekly schedule (7%), and with less alkylators in the preparative regimen.

Inotuzumab single-agent therapy was highly active, safe, and convenient in patients with refractory-relapsed ALL. A weekly dose schedule appeared to be equally effective and less toxic than a single-dose schedule. Cancer 2013;. © 2013 American Cancer Society.

Fatigue and weight loss (FWL) were considered to be associated with circadian disruption based on previous data. Patients with metastatic colorectal cancer (n = 543) from an international phase 3 trial comparing FOLFOX2 with chronoFLO4 were categorized into 4 subgroups according to the occurrence of FWL or other clinically relevant toxicities during the initial 2 courses of chemotherapy. Multivariate Cox models were used to assess the role of toxicity on the time to progression (TTP) and overall survival (OS).

The proportions of patients in the 4 subgroups were comparable in both treatment arms (P = .77). No toxicity was associated with TTP or OS on FOLFOX2. The median OS on FOLFOX2 ranged from 16.4 (95% confidence limits [CL], 7.2-25.6 months) to 19.8 months (95% CL, 17.7-22.0 months) according to toxicity subgroup (P = .45). Conversely, FWL, but no other toxicity, independently predicted for significantly shorter TTP (P < .0001) and OS (P = .001) on chronoFLO4. The median OS on chronoFLO4 was 13.8 months (95% CL, 10.4-17.2 months) or 21.1 months (95% CL, 19.0-23.1 months) according to presence or absence of chemotherapy-induced FWL, respectively.

Early onset chemotherapy-induced FWL was an independent predictor of poor TTP and OS only on chronotherapy. Dynamic monitoring to detect early chemotherapy-induced circadian disruption could allow the optimization of rapid chronotherapy and concomitant improvements in safety and efficacy.

In total, 39 children received IMRT after incomplete resection or disease progression. Three methods of target delineation were used. The first was to delineate the gross tumor volume (GTV) and add a 1-cm margin to create the clinical target volume (CTV) (Method 1; n = 19). The second was to add a 0.5-cm margin around the GTV to create the CTV (Method 2; n = 6). The prescribed dose to the GTV was the same as dose to the CTV for both Methods 1 and 2 (median, 50.4 grays [Gy]). The final method was dose painting, in which a GTV was delineated with a second target volume (2TV) created by adding 1 cm to the GTV (Method 3; n = 14). Different doses were prescribed to the GTV (median, 50.4 Gy) and the 2TV (median, 41.4 Gy).

The 8-year progression-free and overall survival rates were 78.2% and 93.7%, respectively. Seven failures occurred, all of which were local in the high-dose (≥95%) region of the IMRT field. On multivariate analysis, age ≤5 years at time of IMRT had a detrimental impact on progression-free survival.

IMRT provided local control rates comparable to those provided by 2-dimensional and 3-dimensional radiotherapy. Margins ≥1 cm added to the GTV may not be necessary, because excellent local control was achieved by adding a 0.5-cm margin (Method 2) and by dose painting (Method 3).

Surveillance, Epidemiology and End Results (SEER) data were used to determine trends in relative survival by age among 19,000 patients with AML over 3 successive decades (1977-1986, 1987-1996, and 1997-2006). Relative survival rates (RRs) with 95% confidence intervals (CIs) were calculated as measures of survival.

Overall, the RRs increased for each successive decade (1977-1986, 1987-1996, and 1997-2006) in patients ages 65 to 74 years, with improvements in 12-month survival from 20%, to 25%, to 30%, respectively. Findings were similar for 24-month, 36-month, 48-month, and 60-month survival. However, survival rates did not improve in patients aged ≥75 years. The oldest old patients (aged ≥85 years) had the lowest survival rates, with no apparent improvement.

This analysis of a large data set demonstrated that, although overall survival remained unsatisfactory among older patients, it improved in the younger old (ages 65-74 years). Survival of older old AML patients has not been favorably impacted by available AML therapies or supportive care, and intervention in this age group is best undertaken on a clinical trial.

Successive clinical trials using the anti-GD2 MoAb 3F8 (a murine immunoglobulin 3 MoAb specific for GD2) for patients with neuroblastoma involved multiple cycles of standard-dose 3F8 (SD-3F8) (20 mg/m2 daily for 5 days per cycle) or 2 cycles of high-dose 3F8 (HD-3F8) (80 mg/m2 daily for 5 days per cycle) followed by cycles of SD-3F8.

PRES was diagnosed in 5 of 215 patients (2.3%), including 3 of 160 (1.9%) who received SD-3F8 and 2 of 55 (3.6%) who received HD-3F8 (P = .6). All 5 patients had a rapid return to clinical-radiologic baseline. PRES occurred in 3 of 26 patients (11.5%) whose prior treatment included external-beam radiotherapy to the brain (2 of 6 patients status-post total body irradiation and 1 of 20 patients status-post craniospinal irradiation) compared with 2 of 189 patients (1.1%) who had not received prior brain irradiation (P = .01). Hypertension, which is strongly linked to PRES, reached grade 3 toxicity in 12 of 215 patients (5.6%), including the 5 patients with PRES and 7 patients without PRES.

Patients who receive anti-GD2 MoAb immunotherapy should be closely monitored for, and undergo urgent treatment or evaluation of, symptoms that may herald PRES (eg, hypertension or headaches). Prior brain irradiation may be a predisposing factor for PRES with this immunotherapy. Cancer 2013. © 2013 American Cancer Society.

In total, 633 men with known tobacco history at consultation underwent definitive EBRT between 1988 and 2008. Tobacco use was defined as positive (current or prior) or negative (never). The median EBRT dose was 74 gray (Gy). In univariate analysis, tobacco use and other prognostic factors were compared with disease control and toxicity. Multivariable analysis included tobacco use and the covariates that were associated with outcome on univariate analysis (P < .1).

The rate of 5-year freedom from biochemical failure (FFBF) was 76% for current smokers, 81% for prior smokers, and 87% for never smokers (P < .02). Risk group, the percentage of involved cores, and EBRT dose ≥74 Gy were associated with FFBF (all P < .01). On multivariable analysis, smoking was not associated with FFBF (P = .19). Factors that were associated with late grade ≥2 genitourinary toxicity on univariate analysis included positive tobacco history, intensity-modulated radiotherapy, and EBRT dose ≥74 Gy (all P < .05). Prior transurethral resection of the prostate (P < .01) and current smoking status (P = .06) were associated with grade ≥3 toxicity. On multivariable analysis, a positive tobacco history was associated with grade ≥2 toxicity (hazard ratio, 1.45; P < .02), and current smoking status was associated with grade ≥3 toxicity (hazard ratio, 3.02; P < .05). Tobacco use was not associated with late gastrointestinal toxicity.

In men who are receiving EBRT for prostate cancer, tobacco use may be associated with higher rates of late grade ≥2 toxicity, and current smokers may have higher rates of late grade ≥3 genitourinary toxicity. Cancer 2013. © 2013 American Cancer Society.

We identified 9193 men diagnosed with stage I seminoma (ages 15-70 years) in the population-based SEER registries (1973-2001). We calculated survival estimates, standardized mortality ratios (SMRs), and adjusted hazard rates (AHRs).

During 121,037 person-years of follow-up (median, 12.3 years), 915 deaths (SMR, 1.23; 95% CI, 1.16-1.32) were reported, with significant excesses for suicide (n = 39; SMR, 1.45; 95% CI, 1.06-1.98), infection (n = 58; SMR, 2.32; 95% CI, 1.80-3.00), and second malignant neoplasms (SMNs; n = 291; SMR, 1.81; 95% CI, 1.61-2.03), but not CVD (n = 201; SMR, 0.91; 95% CI, 0.80-1.05). After radiotherapy (78% patients), CVD deaths were not increased (n = 158; SMR, 0.89; 95% CI, 0.76-1.04), in contrast to SMN deaths (n = 246; SMR, 1.89; 95% CI, 1.67-2.14). SMN mortality was higher among patients administered radiotherapy than among those not given radiotherapy (AHR, 1.36; 95% CI, 0.99-1.88; P = .059), with a cumulative 15-year risk of 2.64% (95% CI, 2.19-3.16). Suicide, although rare, accounted for 1 in 230 deaths.

Modern radiotherapy as applied in this large population-based study is not associated with excess CVD mortality. Although increased all-cause mortality exists, cumulative SMN risk is considerably smaller than reported in historical series, but additional follow-up will be required to characterize long-term trends. The increased risk of suicide, previously unreported in men with stage I seminoma, requires confirmation. Cancer 2013. © 2013 American Cancer Society.

The current study combined the cytotoxic agent TMZ with the cytostatic agent lonafarnib for patients with recurrent glioblastoma to establish a maximum tolerated dose (MTD) of the combination and its preliminary efficacy. Three dose cohorts of lonafarnib were studied in the phase 1 component of the trial (100 mg twice daily [bid], 150 mg bid, and 200 bid) with dose-dense schedule of TMZ (150 mg/m² daily) administered in an alternating weekly schedule. After establishing the MTD of lonafarnib, a subsequent expansion phase 1b was undertaken to evaluate efficacy, primarily measured by 6-month progression-free survival (PFS-6).

Fifteen patients were enrolled into the phase 1 component and 20 patients into the phase 1b component. The MTD of lonafarnib in combination with TMZ was 200 mg bid. Among the patients enrolled into the study, 34 were eligible for 6-month progression evaluation and 35 patients were evaluable for time-to-progression analysis. The PFS-6 rate was 38% (95% confidence interval [CI] = 22%, 56%) and the median PFS was 3.9 months (95% CI = 2.5, 8.4). The median disease-specific survival was 13.7 months (95% CI = 8.9, 22.1). Hematologic toxicities, particularly lymphopenia, were the most common grade 3 and 4 adverse events. There were no treatment-related deaths.

These results demonstrate that TMZ can be safely combined with a farnesyltransferase inhibitor and that this regimen is active, although the current study cannot determine the relative contributions of the 2 agents or the contribution of the novel administration schedule.

In this matched cohort study, patients in the case group were survivors of incident lymphomas that occurred between 1997 and June 2010. Controls were living, cancer-free, HIV-infected patients who were matched to cases at a 4:1 ratio by age, sex, nadir CD4 cell count, and year of HIV diagnosis. The date of lymphoma diagnosis served as the baseline in cases and in the corresponding controls.

In total, 62 patients (cases) who had lymphoma (20 with Hodgkin disease [HD] and 42 with non-Hodgkin lymphoma [NHL]) were compared with 211 controls. The overall median follow-up was 4.8 years (interquartile range, 2.0-7.9 years). The CD4 cell count at baseline was 278 cells/mm³ (interquartile range, 122-419 cells/mm³) in cases versus 421 cells/mm³ (interquartile range, 222-574 cells/mm³) in controls (P = .003). At the last available visit, the CD4 cell count was 412 cells/mm³ (range, 269-694 cells/mm³) in cases versus 518 cells/mm³ (interquartile range, 350-661 cells/mm³) in controls (P = .087). The proportion of patients who achieved virologic success increased from 30% at baseline to 74% at the last available visit in cases (P = .008) and from 51% to 81% in controls (P = .0286). Patients with HD reached higher CD4 cell counts at their last visit than patients with NHL (589 cells/mm³ [range, 400-841 cells/mm³] vs 332 cells/mm³ [interquartile range, 220-530 cells/mm³], respectively; P = .003). Virologic success was similar between patients with HD and patients with NHL at the last visit. Forty cases (65%) and 76 controls (36%) experienced at least 1 clinical event after baseline (P < .0001); cases were associated with a shorter time to occurrence of the first clinical event compared with controls (P < .0001).

HIV-infected lymphoma survivors experienced more clinical events than controls, especially during the first year of follow-up, but they reached similar long-term immunologic and virologic outcomes. Cancer 2013;. © 2013 American Cancer Society.

We reviewed the records of all patients who were treated for relapsed high-grade osteosarcoma at our institution between 1970 and 2004. Postrelapse event-free survival (PREFS) and postrelapse survival (PRS) were estimated, and outcome comparisons were made using an exact log-rank test.

The 10-year PREFS and PRS of the 110 patients were 11.8% ± 3.5% and 17.0% ± 4.3%, respectively. Metastasis at initial diagnosis (14%), and relapse in lung only (75%) were not significantly associated with PREFS or PRS. Time from initial diagnosis to first relapse (RL1) ≥18 months (43%), surgery at RL1 (76%), and ability to achieve second complete remission (CR2, 56%) were favorably associated with PREFS and PRS (P  ≤  0.0002). In patients without CR2, chemotherapy at RL1 was favorably associated with PREFS (P = 0.01) but not with PRS. In patients with lung relapse only, unilateral relapse and number of nodules ( ≤ 3) were associated with better PREFS and PRS (P  ≤  0.0005); no patients with bilateral relapse survived 10 years. The median PREFS after treatment with cisplatin, doxorubicin, methotrexate, and ifosfamide was 3.5 months (95% confidence interval, 2.1-5.2), and the median PRS was 8.2 months (95% confidence interval, 5.2-15.1).

Late relapse, surgical resection, and unilateral involvement (in lung relapse only) favorably impact outcome after relapse. Surgery is essential for survival; chemotherapy may slow disease progression in patients without CR2. These data are useful for designing clinical trials that evaluate novel agents.

To reassess the current treatment strategies of centrally located LGG, we compared the long-term survival and morbidity of different treatment regimens. Medical records of patients primarily treated at Texas Children's Cancer and Hematology Centers between 1987 and 2008 were reviewed.

Forty-seven patients with a median follow-up of 79 months were included in the analysis. The 5-year overall survival and progression-free survival (PFS) for all patients were 96% and 53%, respectively. The 5-year PFS for those treated initially with RT (12 patients; median age, 11 years [range, 3-15 years]) and with chemotherapy (28 patients; median age, 2 years [range 0-8 years]) were 76% and 37%, respectively (log-rank test P = .02). Among children who progressed after chemotherapy, the 5-year PFS after salvage RT was 55%. Patients diagnosed at a younger age (<5 years) were more likely to experience endocrine abnormalities (Fisher exact test; P<.00001).

Effective and durable tumor control was obtained with RT as initial treatment. In younger patients, chemotherapy can delay the use of RT; however, frequent progression and long-term morbidity are common. More effective and less toxic therapies are required in these patients, the majority of whom are long-term survivors. Cancer 2013;. © 2013 American Cancer Society.

Patients who had a diagnosis of CML were identified using the SEER 19 registries database. Patients who were included had SEER diagnosis codes for CML not otherwise specified (code 9863) and BCR/ABL-positive CML (code 9875) diagnosed between January 2000 and December 2005. Patients were divided into cohorts based on age at diagnosis: ages 15 to 44 years, 45 to 64 years, 65 to 74 years, and 75 to 84 years. OS was estimated using the Kaplan-Meier method, and Cox regression was used to estimate predictors of patient survival.

In total, 5138 patients with a new CML diagnosis were identified. Five-year OS improved for all patients between the years 2000 and 2005. Compared with patients who were diagnosed in 2000, 5-year survival improved among patients ages 15 to 44 years (hazard ratio [HR] for mortality, 0.424; P < .0001), ages 45 to 64 years (HR, 0.716; P = .0315), and ages 65 to 74 years (HR, 0.692; P = .0126); and patients ages 75 to 84 years had an increased 5-year OS rate from 19.2% in 2000 to 36.4% in 2005 (HR, 0.568; P < .0001).

OS at 5 years improved among all patients, including those ages 75 to 84 years, a group with historically poor outcomes. However, older age retained an association with worse survival, suggesting opportunities for further progress. Cancer 2013;. © 2013 American Cancer Society.

Two established simulation models examine 6 strategies that include increased screening and/or treatment or elimination of obesity versus continuation of current patterns. The models use common national data on incidence and obesity prevalence, competing causes of death, mammography characteristics, treatment effects, and survival/cure. Parameters are modified based on obesity (defined as BMI ≥ 30 kg/m²). Outcomes are presented for the year 2025 among women aged 25+ and include numbers of cases, deaths, mammograms and false-positives; age-adjusted incidence and mortality; breast cancer mortality reduction and deaths averted; and probability of dying of breast cancer.

If current patterns continue, the models project that there would be about 50,100-57,400 (range across models) annual breast cancer deaths in 2025. If 90% of women were screened annually from ages 40 to 54 and biennially from ages 55 to 99 (or death), then 5100-6100 fewer deaths would occur versus current patterns, but incidence, mammograms, and false-positives would increase. If all women received the indicated systemic treatment (with no screening change), then 11,400-14,500 more deaths would be averted versus current patterns, but increased toxicity could occur. If 100% received screening plus indicated therapy, there would be 18,100-20,400 fewer deaths. Eliminating obesity yields 3300-5700 fewer breast cancer deaths versus continuation of current obesity levels.

Maximal reductions in breast cancer deaths could be achieved through optimizing treatment use, followed by increasing screening use and obesity prevention. Cancer 2013;. © 2013 American Cancer Society.

One hundred seventy-one patients who underwent resection of CLM after preoperative chemotherapy at 4 centers were studied. Pathologic response—defined as the proportion of tumor cells remaining (complete, 0%; major, <50%; minor, ≥50%) and tumor thickness at the tumor-normal liver interface (TNI) (<0.5 mm, 0.5 to <5 mm, ≥5 mm)—was assessed by a central pathology reviewer and local pathologists.

Pathologic response was complete in 8% of patients, major in 49% of patients, and minor in 43% of patients. Tumor thickness at the TNI was <0.5 mm in 21% of patients, 0.5 to <5 mm in 56% of patients, and ≥5 mm in 23% of patients. On multivariate analyses, using either pathologic response or tumor thickness at TNI, pathologic response (P = .002, .009), tumor thickness at TNI (P = 0.015, <.001), duration of preoperative chemotherapy (P = .028, .043), number of CLM (P = .038, . 037), and margin (P = .011, .016) were associated with DFS. In a multivariate analysis using both parameters, tumor thickness at TNI (P = .004, .015), duration of preoperative chemotherapy (P = .025), number of nodules (P = .027), and margin (P = .014) were associated with DFS. Tumor size by pathology examination was the predictor of pathologic response. Predictors of tumor thickness at the TNI were tumor size and chemotherapy regimen. There was near perfect agreement for pathologic response (κ = .82) and substantial agreement (κ = .76) for tumor thickness between the central reviewer and local pathologists.

Pathologic response and tumor thickness at the TNI are valid predictors of DFS after preoperative chemotherapy and surgery for CLM. Cancer 2013. © 2013 American Cancer Society.

Two databases were combined which contained patients treated from 1999 to 2008 by lobectomy (LR, n = 132), sublobar resection (SLR, n = 48), and SBRT (n = 137) after negative staging. Univariate and multivariate analysis were performed for survival (OS), total recurrence control (TRC comprises local-regional and distant control), and locoregional control (LRC) in our entire population. A matched-pair analysis was also performed that compared surgery and SBRT results. Median follow-up for the entire study population was 25.8 months.

On univariate analysis, OS was significantly worse with SBRT and also correlated with histology, the Charlson comorbidity index, tumor size, and aspirin use; TRC correlated only with histology; and no variable significantly correlated with LRC. OS was significantly poorer for SBRT in the matched-pair analysis than for patients treated with surgery, but TRC and LRC were not significantly different between these groups. Multivariate analyses including propensity score as a covariate (controlling for all factors affecting treatment selection) found that OS correlated only with Charlson comorbidity index, and TRC correlated only with tumor grade. LRC correlated only with tumor size with or without propensity score correction.

This retrospective study has demonstrated similar OS, LRC, and TRC with SBRT or surgery after controlling for prognostic and patient selection factors. Randomized clinical trials are needed to better compare the effectiveness of these treatments. Cancer 2013. © 2013 American Cancer Society.

Patients were randomized 2:1 to receive either open-label barasertib 1200 mg (as a 7-day intravenous infusion) or LDAC 20 mg (subcutaneously twice daily for 10 days) in 28-day cycles. The primary endpoint was the objective complete response rate (OCRR) (complete responses [CR] plus confirmed CRs with incomplete recovery of neutrophils or platelets [CRi] according to Cheson criteria [also requiring reconfirmation of CRi ≥21 days after the first appearance and associated with partial recovery of platelets and neutrophils]). Secondary endpoints included overall survival (OS) and safety.

In total, 74 patients (barasertib, n = 48; LDAC, n = 26) completed ≥1 cycle of treatment. A significant improvement in the OCRR was observed with barasertib (35.4% vs 11.5%; difference, 23.9%; 95% confidence interval, 2.7%-39.9%; P < .05). Although the study was not formally sized to compare OS data, the median OS with barasertib was 8.2 months versus 4.5 months with LDAC (hazard ratio, 0.88; 95% confidence interval, 0.49-1.58; P = .663). Stomatitis and febrile neutropenia were the most common adverse events with barasertib versus LDAC (71% vs 15% and 67% vs 19%, respectively).

Barasertib produced a significant improvement in the OCRR versus LDAC and had a more toxic but manageable safety profile, consistent with previous studies. Cancer 2013. © 2013 American Cancer Society.

Patients with previously untreated mCRC were randomized 1:1:1 to receive continuous axitinib 5 mg twice daily, bevacizumab 5 mg/kg every 2 weeks, or axitinib 5 mg twice daily plus bevacizumab 2 mg/kg every 2 weeks, each in combination with modified 5-fluorouracil/leucovorin/oxaliplatin (FOLFOX-6). The primary endpoint was the objective response rate (ORR).

In all, 126 patients were enrolled from August 2007 to September 2008. The ORR was numerically inferior in the axitinib arm (n = 42) versus the bevacizumab arm (n = 43; 28.6% vs 48.8%; 1-sided P = .97). Progression-free survival (PFS) (11.0 months vs 15.9 months; 1-sided P = .57) and overall survival (OS) (18.1 months vs 21.6 months; 1-sided P = .69) also were numerically inferior in the axitinib arm. Similarly, efficacy endpoints for the axitinib/bevacizumab arm (n = 41) were numerically inferior (ORR, 39%; PFS, 12.5 months; OS, 19.7 months). The patients who received axitinib had fewer treatment cycles compared with other arms. Common all-grade adverse events across all 3 treatment arms were fatigue, diarrhea, and nausea (all ≥49%). Hypertension and headache were more frequent in the patients who received axitinib. Patients in the bevacizumab arm had the longest treatment exposures and the highest rates of peripheral neuropathy.

Neither the addition of continuous axitinib nor the axitinib/bevacizumab combination to FOLFOX-6 improved ORR, PFS, or OS compared with bevacizumab as first-line treatment of mCRC. Cancer 2013. © 2013 American Cancer Society.

A cohort of 2230 patients with incident SCCHN was reviewed for development of SPM. Kaplan-Meier analysis, log-rank testing, and Cox proportional hazards models were used to detect the impact of various factors, including index tumor site, on SPM risk.

The SPM rate was lower for patients with index SCCOP than for patients with index nonoropharyngeal cancer (P < .001). Among patients with SCCOP, former smokers had a 50% greater risk of SPM, and current smokers had a 100% greater risk of SPM than never-smokers (P_trend = .008). Also among patients with SCCOP, those with the classic SCCHN phenotype had an SPM risk similar to that of patients with index nonoropharyngeal cancers; those with a typical human papillomavirus phenotype had a very low SPM risk. SPM most commonly occurred at nontobacco-related sites in patients with index SCCOP and at tobacco-related sites in patients with index nonoropharyngeal cancers.

In patients with SCCHN, index cancer site and smoking status affect the risk and distribution of SPM. Cancer 2013. © 2013 American Cancer Society.

Patients with GCT seen over a 20-year period at Memorial Sloan-Kettering Cancer Center were identified. Primary tumor site and histology were compared for patients aged ≥ 50 years at diagnosis versus younger men. For patients aged ≥ 50, individual chart review was performed and treatment delays, changes, and toxicities were recorded for those treated with first-line chemotherapy.

Of 4235 diagnoses of GCT, 3999 (94.4%) were made at age < 50 versus 236 (5.6%) at age ≥ 50. Compared with patients diagnosed before age 50, older men more frequently had seminoma (62.7% versus 36.7%) and less frequently, nonseminoma (34.7% versus 63.2%) (P < .0001). Predominant histology switched from nonseminoma to seminoma around age 35. Distribution of primary sites also differed for older versus younger men (testis: 89.4% versus 92.9%; retroperitoneal: 3.8% versus 0.7%; CNS 0% versus 1.7%) except for mediastinal primary tumors, which remained constant across age groups. Fifty patients age ≥ 50 received first-line platinum-based chemotherapy; 30 experienced complications leading to treatment discontinuation, delay ≥ 7 days, or regimen change. Twenty-two (44%) patients experienced neutropenic fever, 6 despite prophylactic growth factor support. Estimated 5-year survival for chemotherapy-treated patients was 84.9%.

Men aged ≥ 50 years comprise less than 10% of GCT diagnoses and have distinct clinical and histological characteristics as compared with younger patients. Although complications from chemotherapy occur frequently in older men, prognosis remains excellent when risk-directed treatment is administered with curative intent.

Immunohistochemistry was performed on primary and distant metastatic breast cancers and benign breast tissue using antibodies against AR, AR-Ser(P)-213, and AR-Ser(P)-650. The levels of cytoplasmic and nuclear expression were scored semiquantitatively using a histoscore.

Nuclear staining of AR was observed in all benign breast tissue and 67% of cancer cases. Nuclear and cytoplasmic AR-Ser(P)-213 was increased in breast cancers 2-fold (P = .0014) and 1.7-fold (P = .05), respectively, compared with benign controls, whereas nuclear and cytoplasmic AR-Ser(P)-650 expression was decreased in tumors by 1.9-fold and 1.7-fold (both P < .0001), respectively. Increased expression of nuclear or cytoplasmic AR-Ser(P)-213 was observed in metastatic breast cancers (1.3-fold, P = .05), ER-negative (2.6-fold, P = .001), and invasive ductal carcinoma (6.8-fold, P = .04). AR-Ser(P)-650 expression was downregulated in lymph node-positive breast cancers (1.4-fold, P = .02) but was upregulated in invasive ductal carcinomas (3.2-fold, P < .0001) and metastases (1.5-fold, P = .003). Moreover, in ER-negative breast cancers, nuclear AR-Ser(P)-650 was decreased (1.4-fold, P = .005), and cytoplasmic AR-Ser(P)-650 was increased (1.4-fold, P = .003).

AR and its phosphorylation at serines 213 and 650 are differentially expressed in breast cancer tumorigenesis and progression. Phosphorylation of AR at serines 213 and 650 is increased in ER-negative breast cancers, ductal carcinomas, and metastases and may have predictive value in breast cancer prognosis.

The authors performed cross-sectional assessments of mammography screening in 2005, 2008, and 2011 using data from the National Health Interview Survey, a nationally representative, in-person, household survey of the civilian, noninstitutionalized US population. In total, 27,829 women ages ≥40 years responded to the 2005, 2008, or 2011 surveys and reported about their mammography use. The primary outcome assessed was self-reported mammography screening in the past year.

When adjusted for race, income, education level, insurance, and immigration status, mammography rates increased slightly from 2008 to 2011 (from 51.9% to 53.6%; P = .07) and did not decline within any age group. Among women ages 40 to 49 years, screening rates were 46.1% in 2008 and 47.5% in 2011 (P = 0.38). For women ages 50 to 74, screening rates were 57.2 in 2008 and 59.1 in 2011 (P = 0.09).

Mammography rates did not decrease among women aged >40 years after publication of the USPSTF recommendations in 2009, suggesting that the vigorous policy debates and coverage in the media and medical literature have had an impact on the adoption of these recommendations.

In this multicenter, 1-stage, phase 2 trial of sorafenib (800 mg daily), the primary endpoint, which was chosen by default, was the 9-month progression-free rate. All patients had documented progressive disease at the time of study entry.

Fifteen patients were enrolled between June 2009 and February 2011. The median age was 57 years (range, 31-76 years), and the ratio of men to women was 9:6. The performance status was zero in 10 patients and 1 in 5 patients. Twelve patients had metastases, mainly in the lung (12 patients), liver (5 patients), and bone (3 patients). Five patients had received prior chemotherapy (doxorubicin in 5 patients and taxane in 3 patients). The median sorafenib treatment duration was 124 days (range, from 27 to >271 days). Seven patients required dose reductions or transient treatment discontinuation. The 9-month progression-free rate was 30.7% (4 of 13 patients). The 2-month, 4-month, and 6-month progression-free rate was 84.6% (11 of 13 patients), 46.4% (6 of 13 patients), and 38.4% (5 of 13 patients), respectively. Two partial responses were observed that lasted 2 months and 9 months.

Further clinical trials exploring sorafenib as treatment of progressive EHE are needed. Cancer 2013;000:000-000. © 2013 American Cancer Society.

Navigation services were initiated at an NAPBC-accredited comprehensive breast center in July 2010. Two 9-month study intervals were chosen for comparison of timeliness of care: October 2009 through June 2010 and October 2010 through June 2011. All patients with breast cancer diagnosed in the cancer center with stage 0 to III disease during the 2 study periods were identified by retrospective cancer registry review. Time from diagnosis to initial oncology consultation was measured in business days, excluding holidays and weekends.

Overall, 176 patients met inclusion criteria: 100 patients prior to and 76 patients following nurse navigation implementation. Nurse navigation was found to significantly shorten time to consultation for patients older than 60 years (B = −4.90, P = .0002). There was no change in timeliness for patients 31 to 60 years of age.

Short-term analysis following navigation implementation showed decreased time to consultation for older patients, but not younger patients. Further studies are indicated to assess the long-term effects and durability of this quality improvement initiative. Cancer 2013;000:000-000. © 2013 American Cancer Society.

Tubulin-β-III and p-glycoprotein were quantified by real-time polymerase chain reaction in 48 fresh-frozen tissue samples and 13 cell lines. Copy number was correlated with immunohistochemistry and overall survival. Median inhibitory concentration (IC₅₀) was determined using viability and metabolic assays. Impact of tubulin-β-III knockdown on IC₅₀ was assessed with small interfering RNAs.

USC overexpressed tubulin-β-III but not p-glycoprotein relative to OSC in both fresh-frozen tissues (552.9 ± 106.7 versus 202.0 ± 43.99, P = .01) and cell lines (1701.0 ± 376.4 versus 645.1 ± 157.9, P = .02). Tubulin-β-III immunohistochemistry reflected quantitative real-time polymerase chain reaction copy number and overexpression stratified patients by overall survival (copy number ≤ 400: 615 days; copy number > 400: 165 days, P = .049); p-glycoprotein did not predict clinical outcome. USCs remained exquisitely sensitive to patupilone in vitro despite tubulin-β-III overexpression (IC_50,USC 0.245 ± 0.11 nM versus IC_50,OSC 1.01 ± 0.13 nM, P = .006).

Tubulin-β-III overexpression in USCs discriminates poor prognosis, serves as a marker for sensitivity to epothilones, and may contribute to paclitaxel resistance. Immunohistochemistry reliably identifies tumors with overexpression of tubulin-β-III, and a subset of individuals likely to respond to patupilone and ixabepilone. Epothilones warrant clinical investigation for treatment of USCs. Cancer 2013;000:000-000. © 2013 American Cancer Society.

Between January 2000 and July 2007, the authors retrospectively analyzed 390 patients who had triple-negative breast cancer with T1/T2 tumors and from zero to 3 positive lymph nodes (pathologic T1-T2N0-N1) who underwent modified radical mastectomy without postmastectomy radiotherapy at the author's institution. The 5-year cumulative incidence for events was calculated using Kaplan-Meier analysis, and subgroups were compared using the log-rank test. Multivariate analysis was performed using a Cox proportional hazards model.

Overall, 86.4% of patients received chemotherapy. At a median follow-up of 60.5 months, the 5-year cumulative rates of local recurrence, regional recurrence, LRR, and distant metastasis were 5.4%, 4.7%, 8%, and 13.4%, respectively. On multivariate analysis, age <50 years, the presence of lymphovascular invasion, grade 3 tumor, and 3 involved lymph nodes were associated significantly with an increased risk of LRR. The 5-year LRR rate for patients who had 0 or 1 risk factor, 2 risk factors, and 3 or 4 risk factors was 4.2%, 25.2%, and 81% (P < .0001), respectively. The presence of lymphovascular invasion and having 3 involved lymph nodes were statistically significant predictors of regional recurrence, and the patients who had regional recurrence had a significantly greater risk of distant metastases compared with patients who had local recurrence (59.1% vs 20.9%; P  <  .0001).

Several risk factors were identified in this study that correlated independently with a greater incidence of LRR in patients who had early stage triple-negative breast cancer. The current results indicated that postmastectomy radiotherapy should be considered for those patients who have 2 or more of these factors. Cancer 2013;119:2366-2374. © 2013 American Cancer Society.

Patients initiating AIs (n = 91) were surveyed at the time of AI initiation and at 6 repeated assessments over 1 year. A comparison group of postmenopausal women without breast cancer (n = 177) completed concomitantly timed surveys. Numeric rating scales (0–10) were used to measure pain in 8 joint pair groups (bilateral fingers, wrists, elbows, shoulders, hips, knees, ankles, and toes). Poisson regression models were used to analyze arthralgia trajectories and risk factors.

By week 6, the AI-initiating group had more severe arthralgia than did the comparison group (ratio of means = 1.8, 95% confidence interval = 1.24-2.7, P = .002), adjusting for baseline characteristics. Arthralgia then worsened further over 1 year in the AI group. Menopausal symptom severity and existing joint-related comorbidity at baseline among women initiating AI were associated with more severe arthralgia over time.

Patients initiating AI should be told about the timing of arthralgia over the first year of therapy, and advised that it does not appear to resolve over the course of a year. Menopausal symptoms and joint-related comorbidity at AI initiation can help identify patients at risk for developing AI-related arthralgia. Cancer 2013;119:2375–2382. © 2013 American Cancer Society.

Male cancer patients treated with crizotinib had total testosterone levels measured and results compared with non-crizotinib-treated patients. Albumin, sex hormone-binding globulin (SHBG), follicle-stimulating hormone (FSH), and/or luteinizing hormone (LH) were tracked longitudinally. A subset of patients had free testosterone levels measured and a hypogonadal screening questionnaire administered. Patients receiving subsequent testosterone supplementation were assessed for symptomatic improvement.

Mean total testosterone levels were −25% below the lower limit of normal (LLN) in 32 crizotinib-treated patients (27 of 32 patients below LLN, 84%) compared with +29% above LLN in 19 non-crizotinib-treated patients (6 of 19 below LLN, 32%), P = .0012. Levels of albumin and SHBG (which both bind testosterone) declined rapidly with crizotinib, but so did FSH, LH, and free testosterone, suggesting a centrally mediated, true hypogonadal effect. Mean free testosterone levels were −17% below LLN (19 of 25 patients below LLN, 76%). Eighty-four percent (16 of 19) with low free levels, and 79% (19/24) with low total levels had symptoms of androgen deficiency. Five of 9 patients (55%) with low testosterone given testosterone supplementation had improvement in symptoms, coincident with increases in testosterone above LLN.

Symptoms of androgen deficiency and free or total/free testosterone levels should be tracked in male patients on crizotinib with consideration of testosterone replacement as appropriate. Cancer 2013;119:2383-2390. © 2013 American Cancer Society.

Pretreatment serum SCCAg measurements in patients with histologically diagnosed squamous cell carcinoma of the anal canal and margin who received chemoradiation were compared with clinical tumor classification and lymph node status for prognostic/predictive ability, including 1) tumor response after the completion of chemoradiation treatment, 2) disease recurrence, and 3) overall survival. Clinical measurements and scores were compared using Spearman rank tests, and survival was assessed in both univariate and multivariate survival analyses.

The median pretreatment levels of SCCAg according to clinical tumor classification and clinical lymph node status were 0.8 μg/L in T1 tumors, 1.90 μg/L in T2 tumors, 2.5 μg/L in T3 tumors, 3.8 μg/L in T4 tumors, 1.35 μg/L in patients with N0 status, and 3.05 μg/L in patients with N0+ status (correlation coefficient: T-classification, 0.43; lymph node status, 0.38; both P < .00001). Of the patients who had normal SCCAg levels, 95% achieved a complete response after initial treatment; and, of those who had elevated SCCAg levels, 86% achieved a complete response (P = .05). Overall survival (hazard ratio, 2.5; P = .007) and disease-free survival (hazard ratio, 2.2; P = .058) were worse for those who had elevated pretreatment serum SCCAg concentrations.

Pretreatment SCCAg levels in patients with squamous cell carcinoma of the anal canal and margin were correlated with clinical tumor classification and clinical lymph node status. Elevated levels of SCCAg were associated with a reduced chance of achieving a complete response and an increased chance of recurrence and death. The authors recommend further studies to determine the prognostic value of SCCAg in anal squamous cell carcinoma and suggest the potential use of SCCAg as a stratification factor in future trials.

Risk factors included clinicodemographic and laboratory data from veterans who were referred for an initial prostate biopsy. Outcomes were defined as the presence versus the absence of PCa, HGPCa, or low-grade PCa (LGPCa) (Gleason score ≤6) in biopsy specimens. Risk among AOe veterans relative to unexposed veterans was estimated using multivariate logistic regression. Separate models were used to determine whether AOe was associated with an increased risk of PCa, HGPCa, or LGPCa.

Of 2720 veterans who underwent biopsy, PCa was diagnosed in 896 veterans (32.9%), and 459 veterans (16.9%) had HGPCa. AOe was associated with a 52% increase in the overall risk of detecting PCa (adjusted odds ratio, 1.52; 95% confidence interval, 1.07-2.13). AOe did not confer an increase in the risk of LGPCa (adjusted odds ratio, 1.24; 95% confidence interval, 0.81-1.91), although a 75% increase in the risk of HGPCa was observed (adjusted odds ratio, 1.75; 95% confidence interval, 1.12-2.74). AOe was associated with a 2.1-fold increase (95% confidence interval, 1.22-3.62; P < .01) in the risk of detecting PCa with a Gleason score ≥8.

The current results indicated that an increased risk of PCa associated with AOe is driven by an increased risk of HGPCa in men who undergo an initial prostate biopsy. These findings may aid in improved PCa screening for Vietnam-era veterans. Cancer 2013;119:2399-2404. © 2013 American Cancer Society.

CNAs in tumor DNA samples from 125 patients in the discovery cohort who underwent prostatectomy were assayed with high-resolution Affymetrix 6.0 single-nucleotide polymorphism microarrays and then analyzed using the Genomic Identification of Significant Targets in Cancer (GISTIC) algorithm.

The assays revealed 20 significant regions of CNAs, 4 of them novel, and identified the target genes of 4 of the alterations. By univariate analysis, 7 CNAs were significantly associated with early PCa-specific mortality. These included gains of chromosomal regions that contain the genes MYC, ADAR, or TPD52 and losses of sequences that incorporate SERPINB5, USP10, PTEN, or TP53. On multivariate analysis, only the CNAs of PTEN (phosphatase and tensin homolog) and MYC (v-myc myelocytomatosis viral oncogene homolog) contributed additional prognostic information independent of that provided by pathologic stage, Gleason score, and initial prostate-specific antigen level. Patients whose tumors had alterations of both genes had a markedly elevated risk of PCa-specific mortality (odds ratio = 53; 95% CI = 6.92-405, P = 1 × 10⁻⁴). Analyses of 333 tumors from 3 additional distinct patient cohorts confirmed the relationship between CNAs of PTEN and MYC and lethal PCa.

This study identified new CNAs and genes that likely contribute to the pathogenesis of localized PCa and suggests that patients whose tumors have acquired CNAs of PTEN, MYC, or both have an increased risk of early PCa-specific mortality. Cancer 2013;119:2405-2412. © 2013 American Cancer Society.

A prospective observational cohort study was performed of 104 participants aged 64.0 years ± 6.5 years from 3 institutions representing different health care delivery systems. Patients were identified before undergoing transrectal ultrasound-guided prostate biopsy and followed for a median of 28 months. Associations between the comorbidity scores and nonelective hospital admissions were investigated using logistic regression and Cox proportional hazards models.

Among the 104 patients who underwent prostate biopsy, 2 died during the follow-up period. The overall hospital admission rate was 20% (21 of 104 patients). Higher scores on both the TIBI-CaP (≥ 9) and CCI (≥ 3) were found to be significantly associated with an increased odds for hospital admission (odds ratio, 11.3 [95% confidence interval (95% CI), 2.4-53.6] and OR, 5.7 [95% CI, 1.4-22.4]) and hazards ratios (HRs) for time to hospital admission (HR, 3.8 [95% CI, 1.3-11.2] and HR, 3.2 [95% CI, 1.1-9.1]), respectively.

TIBI-CaP and CCI scores were found to successfully predict which patients were at high risk for nonelective hospital admission. These patients are likely to have poorer health and a potentially shortened lifespan. Therefore, comorbidity analysis using these tools may help to identify those patients who are least likely to benefit from prostate cancer therapy and should avoid prostate biopsy.

Participants were 102 patients with head and neck cancer at a large urban cancer center who completed a self-report background and health questionnaire and provided a saliva sample for determination of the long-acting nicotine metabolite cotinine.

Compared with former and never-smokers, current smokers were less educated, less likely to be married or living with a partner, and consumed more alcohol. Cotinine analysis indicated that 4 of 16 (25%) patients who denied past-month cigarette use misrepresented their true smoking status. Of patients with oropharyngeal cancer, 74% were confirmed as HPV-positive, and compared with HPV-negative patients, they were younger, more likely to be married/partnered and of Caucasian race, and reported more past vaginal and oral sexual partners. Only one-third of HPV-positive patients were aware of their HPV disease status.

Cigarette smoking is associated with engagement in other modifiable risk factors in patients with head and neck cancer. Self-report measures of smoking may not accurately depict true smoking status. HPV-positive cancer patients were more likely to endorse a history of multiple sexual partners. Regular screening and targeted interventions for these distinct risk factors are warranted.

In this single-institution, retrospective analysis, local control was the primary endpoint, and disease-specific survival (DSS) was the secondary endpoint. Differences in survival were determined using the log-rank test, and survival curves were generated using the Kaplan-Meier method.

One hundred forty-four patients (79 men and 65 women; median age, 64.1 years; mean follow-up, 3.3 years) underwent surgery alone for oral SCC with curative intent and were recorded as having close tumor margins on histology. The local control rate for all patients who underwent surgery alone was 91% (95% confidence interval, 81.9%-95.2%), and the DSS rate was 84% (95% confidence interval, 74.0%-89.9%) at 5 years. There was no pattern of worse local control or DSS rates with the ordered stratification of close margins. The 5-year local control rates for having 0, 1, 2, and 3 additional adverse features were 100%, 96%, 83%, and 71%, respectively (P = .004; trend test).

Surgery alone without postoperative adjuvant therapy offered acceptable local control in patients who had close margin status as their only adverse feature and may be reasonable in the presence of 1 other adverse clinicopathologic feature. Cancer 2013;119:2427-2437. © 2013 American Cancer Society.

A total of 200 patients with multiple myeloma who developed disease recurrence after treatment with upfront ASCT and received an autologous retransplantation as salvage therapy at the study center over a period of 15 years were retrospectively reviewed. The objective of the current study was to evaluate the role of salvage ASCT in terms of efficacy, particularly taking into account the impact of novel agents.

The median progression-free survival (PFS) and overall survival after salvage ASCT were 15.2 months and 42.3 months, respectively. The overall response rate (a partial response or greater) was 80.4% at day 100, excluding 6 patients who died before assessment. Factors associated with improved PFS and overall survival after salvage ASCT included an initial PFS of > 18 months after upfront ASCT, bortezomib-containing or lenalidomide-containing therapies for reinduction, response to reinduction, and an International Staging System stage of I before salvage ASCT.

Salvage ASCT is capable of achieving sustained disease control in patients with multiple myeloma. The use of lenalidomide and bortezomib for reinduction has improved the results after salvage ASCT, suggesting that novel agents and salvage ASCT are complementary rather than alternative treatment approaches.

Patients were grouped according to baseline BMI as follows: normal (BMI <25 kg/m²), overweight (BMI ≥25 kg/m² and <30 kg/m²), and obese (BMI ≥30 kg/m²). Disease-free survival (DFS) was estimated using the Kaplan-Meier method. Comparisons between treatment arms A, B, and C (chemotherapy with or without trastuzumab) were performed using a stratified Cox proportional hazards model.

Analysis was completed on 3017 eligible patients. Obese patients were more likely to be older and postmenopausal (P < .0001 for both), to have larger tumors (P = .002), and to have positive lymph nodes (P = .004). In the pooled analysis cohort, differences in DFS among the BMI groups were statistically significant (5-year DFS rate: 82.5%, 78.6%, and 78.5% for normal weight, overweight, and obese women, respectively; log-rank P = .02). The adjusted hazard ratio comparing the DFS of overweight women with the DFS of normal women was 1.30 (95% confidence interval, 1.06-1.61); and, comparing the DFS of obese women with the DFS normal women, the adjusted hazard ratio was 1.31 (95% confidence interval, 1.07-1.59). There were no statistically significant differences in DFS by weight group for women within any trial arm.

Patients with early stage, HER2-positive breast cancer and normal BMI had a better 5-year DFS compared with overweight and obese women. The current results indicated that adjuvant trastuzumab improves clinical outcome regardless of BMI. Cancer 2013;119:2447-2454. © 2013 American Cancer Society.

Women with a clinical diagnosis of breast cancer−related lymphedema (BCRL) for 0.5-5 years and with affected arm circumference ≥2 cm larger than unaffected arm received acupuncture treatment twice weekly for 4 weeks. Affected and unaffected arm circumferences were measured before and after each acupuncture treatment. Response, defined as ≥30% reduction in circumference difference between affected/unaffected arms, was assessed. Monthly follow-up calls for 6 months thereafter were made to document any complications and self-reported lymphedema status.

Among 37 enrolled patients, 33 were evaluated; 4 discontinued due to time constraints. Mean reduction in arm circumference difference was 0.90 cm (95% CI, 0.72-1.07; P < .0005). Eleven patients (33%) exhibited a reduction of ≥30% after acupuncture treatment. Seventy-six percent of patients received all treatments; 21% missed 1 treatment, and another patient missed 2 treatments. During the treatment period, 14 of the 33 patients reported minor complaints, including mild local bruising or pain/tingling. There were no serious adverse events and no infections or severe exacerbations after 255 treatment sessions and 6 months of follow-up interviews.

Acupuncture for BCRL appears safe and may reduce arm circumference. Although these results await confirmation in a randomized trial, acupuncture can be considered for women with no other options for sustained arm circumference reduction. Cancer 2013;119:2455-2461. © 2013 American Cancer Society.

Women aged ≥18 years who underwent mastectomy for cancer were identified in the Nationwide Inpatient Sample database (2000-2009) and were classified according to their immediate breast reconstruction (IBR) status. Trends in rates of IBR were described for each insurance category. Multivariable logistic regression analysis with adjustment for age, race, estimated household income, and Elixhauser comorbidity index was performed to evaluate the relation between insurance status and IBR.

In total, 168,236 patients were identified who underwent a mastectomy during the study interval. Across the 10-year study period, rates of IBR increased 4.2-fold in Medicaid patients, 2.9-fold in Medicare patients, 2.6-fold in privately insured patients, and 2.1-fold in self-pay patients (P < .01). However, after adjustment for confounders, women without private insurance were less likely to undergo IBR compared with women who had private insurance (Medicaid: odds ratio [OR], 0.34; 95% confidence interval [CI], 0.32-0.37; Medicare: OR, 0.53; 95% CI, 0.49-0.58; self-pay: OR, 0.43; 95% CI, 0.37-0.50; other types of nonprivate insurance: OR, 0.64, 95% CI, 0.56-0.73).

After the enactment of policy designed to improve access to IBR, Medicaid and Medicare patients experienced the greatest relative increase in rates of IBR. Although policy changes had the most impact on traditionally underserved populations, disparities still exist. Future studies should endeavor to understand why such disparities have persisted.

This was a cross-sectional, population-based study using a linked data set comprised of death certificate data for the state of Ohio for the years 2004-2007 and data from the publicly funded mental health system in Ohio. Decedents with mental illness were those identified concomitantly in both data sets. We used age-adjusted standardized mortality ratios (SMRs) in race- and sex-specific person-year strata to estimate excess deaths for each of the anatomic cancer sites.

Overall, there was excess mortality from cancer associated with having mental illness in all the race/sex strata: SMR, 2.16 (95% CI, 1.85-2.50) for black men; 2.63 (2.31-2.98) for black women; 3.89 (3.61-4.19) for nonblack men; and 3.34 (3.13-3.57) for nonblack women. In all the race/sex strata except for black women, the highest SMR was observed for laryngeal cancer, 3.94 (1.45-8.75) in black men and 6.51 (3.86-10.35) and 6.87 (3.01-13.60) in nonblack men and women, respectively. The next highest SMRs were noted for hepatobiliary cancer and cancer of the urinary tract in all race/sex strata, except for black men.

Compared with the general population in Ohio, individuals with mental illness experienced excess mortality from most cancers, possibly explained by a higher prevalence of smoking, substance abuse, and chronic hepatitis B or C infections in individuals with mental illness. Excess mortality could also reflect late-stage diagnosis and receipt of inadequate treatment. Cancer 2013;119:2469-2476. © 2013 American Cancer Society.

To study the effect of UGT2B17 and UGT2B28 copy number variation (CNV) on CRC risk, 665 Caucasian CRC cases and 621 Caucasian controls were genotyped who had completed extensive demographics and lifestyle questionnaires.

A significant association between the UGT2B17 deletion genotype (0/0) and decreased CRC risk was found when the entire population was analyzed (P = .044). Stratification by sex yielded a decreased risk (P = .020) in men with the UGT2B17 deletion (0/0), but no association was observed in women (P = .724). A significant association between UGT2B17 (0/0) and decreased risk for rectal (P = .0065) but not colon cancer was found. No significant association was found between UGT2B28 CNV and CRC risk.

The UGT2B17 deletion genotype (0/0) was associated with a decreased CRC risk in a Caucasian population. After sex stratification, the association was observed in men but not in women, which is consistent with previous findings that men have higher UGT2B17 expression and activity than women. Because UGT2B17 metabolizes certain nonsteroidal anti-inflammatory drugs and flavonoids with antioxidative properties, individuals with a gene deletion may have higher levels of these protective dietary components.

A total of 2506 AA and 21,454 Caucasian patients diagnosed with localized prostate cancer from 2004 through 2007 and treated within 12 months were included. Linear regression was used to assess potential differences in time to treatment between AA and Caucasian patients, after adjusting for sociodemographic and clinical covariates.

Time from diagnosis to definitive (prostatectomy and radiation) treatment was longer for AA patients in all risk groups, and most pronounced in high-risk cancer (96 versus 105 days, P < .001). On multivariate analysis, racial differences to any and definitive treatment persisted (β = 7.3 and 7.6, respectively, for AA patients). Delay to definitive treatment was longer in high-risk (versus low-risk) disease and in more recent years.

AA patients with prostate cancer experienced longer time from diagnosis to treatment than Caucasian patients with prostate cancer. AA patients appear to experience disparities across all aspects of this disease process, and together these factors in receipt of care plausibly contribute to the observed differences in rates of recurrence and mortality among AA and Caucasian patients with prostate cancer.

A Markov state-transition model was developed to simulate AI use and disease progression in a hypothetical cohort of postmenopausal Medicare beneficiaries with hormone receptor-positive early breast cancer. The analysis was conducted from the societal perspective and considered a lifetime horizon. The main outcome was an incremental cost-effectiveness ratio, which was measured as the cost per quality-adjusted life-year (QALY) gained.

For patients receiving usual prescription coverage, average quality-adjusted survival was 11.35 QALYs, and lifetime costs were $83,002. For patients receiving full prescription coverage, average quality-adjusted survival was 11.38 QALYs, and lifetime costs were $82,728. Compared with usual prescription coverage, full prescription coverage would result in greater quality-adjusted survival (0.03 QALYs) and less resource use ($275) per beneficiary. From the perspective of Medicare, full prescription coverage was cost-effective (incremental cost-effectiveness ratio, $15,128 per QALY gained) but not cost saving.

Providing full prescription coverage for AIs to Medicare beneficiaries with hormone receptor-positive early breast cancer would both improve health outcomes and save money from the societal perspective. Cancer 2013;119:2494-2502. © 2013 American Cancer Society.

Siblings of children with cancer (ages 8-18 years; N = 209) and parents (186 mothers and 70 fathers) completed measures of sibling distress, family functioning, parenting, and parent post-traumatic stress. Associations between sibling distress and each family risk factor were evaluated. Then, family risks were considered simultaneously by calculating cumulative family risk index scores.

After controlling for sociodemographic covariates, greater sibling distress was associated with more sibling-reported problems with family functioning and parental psychological control, lower sibling-reported maternal acceptance, and lower paternal self-reported acceptance. When risk factors were considered together, the results supported a quadratic model in which associations between family risk and sibling distress were stronger at higher levels of risk.

The current findings support a contextual model of sibling adjustment to childhood cancer in which elevated distress is predicted by family risk factors, both alone and in combination. Cancer 2013;119:2503-2510. © 2013 American Cancer Society.
