The post-treatment quality of life (QOL) impacts of receiving precancer-treatment infertility counseling and of pursuing fertility preservation have not been described in large-scale studies of reproductive age women with cancer.
In total, 1041 women who were diagnosed between ages 18 and 40 years responded to a retrospective survey and reported whether they received infertility counseling before cancer treatment and whether they took action to preserve fertility. Five cancer types were included: leukemia, Hodgkin disease, non-Hodgkin lymphoma, breast cancer, and gastrointestinal cancer. Validated QOL scales were used: the Decision Regret Score, the Satisfaction with Life Scale (SWLS), and the brief World Health Organization QOL questionnaire.
Overall, 560 women (61%) who received treatment that potentially could affect fertility were counseled by the oncology team, 45 (5%) were counseled by fertility specialists, and 36 (4%) took action to preserve fertility. Pretreatment infertility counseling by a fertility specialist and an oncologist resulted in lower regret than counseling by an oncologist alone (8.4 vs 11.0; P < .0001). The addition of fertility preservation (6.6 vs 11.0; P < .0001) also was associated with even lower regret scores than counseling by an oncologist alone. Further improvements also were observed in SWLS scores with the addition of fertility specialist counseling (23.0 vs 19.8; P = .09) or preserving fertility (24.0 vs 19.0; P = .05).
Receiving specialized counseling about reproductive loss and pursuing fertility preservation is associated with less regret and greater QOL for survivors, yet few patients are exposed to this potential benefit. Women of reproductive age should have expert counseling and should be given the opportunity to make active decisions about preserving fertility. Cancer 2011;. © 2011 American Cancer Society.
Loss of reproductive potential after cancer treatment negatively impacts quality of life (QOL) in young survivors.1, 2 Recent studies have indicated that the potential iatrogenic loss of fertility—the loss of a potential child—has a profound impact on young women and, at times, may be more stressful than the cancer diagnosis itself.3, 4 This represents a large-scale survivorship issue according to 2006 Surveillance, Epidemiology and End Results (SEER) statistics: Approximately 120,000 women aged <50 years develop cancer each year in the United States.5 However, as recently as 2009, only 34% to 72% of reproductive-age women who were treated for cancer recalled having a discussion about the effects of cancer treatment on future fertility.6 Oncologists have cited many reasons for the lack of such discussions with patients, including lack of knowledge, insufficient time to discuss the issue, perceptions that patients cannot delay treatment, or the perception that, if patients did not raise the issue themselves, then they were not interested.7 Furthermore, most patients have this discussion just before they start cancer treatment and, thus, believe that there is no time to pursue a fertility consultation without delaying planned treatments.8 Yet the risk of treatment-associated infertility and premature menopause is a top concern for patients.9-11
Studies have demonstrated that up to 75% of young women are interested in the opportunity to have children after a cancer diagnosis.3 If women are not informed of the risks to their fertility, then they may lose their ability to take action toward preserving their fertility before cancer treatment.12, 13
Over the past 2 decades, significant advancements have been made in the technology of egg and embryo cryopreservation, and young women with cancer are increasingly being informed about the option to use such technology for fertility preservation. The American Society of Clinical Oncology now recommends that patients who may desire children after treatment should be counseled about fertility preservation options.12 To our knowledge, the effectiveness of fertility counseling and fertility preservation on long-term regret and QOL in a large population of reproductive-age women who are cancer survivors has not been reported previously. Our study is the first to evaluate whether receiving precancer-treatment infertility counseling from an oncology team is associated with improved post-treatment QOL. Second, we evaluated whether consulting a fertility specialist or taking action to preserve fertility is associated with even greater improvements in QOL than only receiving counseling from the oncology team.
MATERIALS AND METHODS
We performed a retrospective survey study, using the California Cancer Registry (CCR) to sample women across the state. All study procedures were approved by the University of California, San Francisco (UCSF) Committee on Human Research.
A computer-generated randomizer was used to sample reproductive age women from the cancer registry who had a history of leukemia, Hodgkin disease, non-Hodgkin lymphoma, breast cancer, or gastrointestinal (GI) cancer. These cancers were chosen for study because they are common, nongynecologic cancer groups that may be treated with fertility-compromising chemotherapy or radiation. Patients were included in the sample if they were ages 18 to 40 years of age at diagnosis and were diagnosed between 1993 and 2007. Among 6709 patients who initially were selected, 4147 patients were excluded because their contact information in the cancer registry was outdated. Letters were sent to the primary physicians of each of the remaining women before we attempted to reach the patients. Then, women also were excluded if their physician thought that participation in the study would cause undue psychological burden (because of severe comorbid mental illness; 30 patients). After exclusions, 2532 patients were contacted for participation in the study. Analyses of QOL included only women who reported treatment with potential to compromise fertility (ie, systemic chemotherapy, pelvic radiation, pelvic surgery, or bone marrow transplantation).
The survey was created at the UCSF and was assessed for readability and content validity—the extent to which our survey accurately assessed reproductive health history and QOL—by 2 independent experts in survey methodology. It was then piloted on 20 patients from the UCSF Center for Reproductive Health for content and readability. The final survey included questions about demographic information, past obstetric and gynecologic history, cancer type and treatment, fertility-preservation actions, and post-treatment QOL.
Post-treatment QOL was conceptualized to include satisfaction with treatment choices and satisfaction with life in addition to a more traditional assessment. QOL was assessed with 3 validated scales: the Decision Regret Scale (DRS), the Satisfaction with Life Scale (SWLS), and the brief World Health Organization QOL questionnaire (WHOQOL-BREF).14-16 The DRS, which was used to assess satisfaction with treatment decisions, is a 5-item scale that measures regret regarding a specific medical decision. The decision of interest in our study was centered on whether participants regretted their decision to undergo (or not undergo) fertility preservation. Scores range from 5 to 25, with higher scores representing greater regret. The SWLS is a 5-item scale that was developed to assess satisfaction with individual lives as a whole. Participants respond to each item ranging from 1 (strongly disagree) to 7 (strongly agree). Summing the items results in a total score ranging from 5 (low satisfaction) to 35 (high satisfaction) Overall QOL was measured with the WHOQOL-BREF, an abbreviated version of the longer WHO QOL scale. It includes 26 items covering 4 domains: physical (daily living, sleep and rest, and work capacity), psychological (self-esteem, body image, and memory), social (personal relationships, social support, and sexual activity), and environmental (financial resources, health care resources, and physical environment). Higher scores reflect better QOL.
The survey was made available in both English and Spanish. A professional translation company (American Language Services, Los Angeles, CA) translated the study materials into Spanish using 2 independent translators. A third bilingual individual checked translations. Paper surveys were created using Cardiff Teleform (Vista, CA). Patients could also complete the survey online through Surveymonkey.com (LLC, Palo Alto, CA).
Women were contacted between January 2010 and September 2010. A contact letter was sent to potential participants explaining the purpose of the survey, the source of the individual's personal contact information (the CCR), and allowing women to opt out of further contact by reaching the UCSF study coordinator. After 1 week, a second mailing was sent that included the written survey, a link to the online survey, a written consent form, a postage-paid return envelope, and an optional refusal postcard. Women were asked to complete and return a written consent form by mail and to return the survey by mail or to complete it online. Women who did not reply within 3 weeks received a reminder follow-up telephone call. Those who did not reply within 2 weeks of the reminder call were sent a reminder postcard with a link to the electronic survey.
Survey data were merged with CCR data with a unique, anonymous identifier code. Statistical analyses were performed using STATA version 11 (Stata Corp., College Station, TX). Statistical significance was defined by 2-sided P values < .05. Power analyses revealed that our sample size would permit us to detect a difference of 1 or greater in DRS, SWLS, and WHO QOL-BREF scores between women who were and were not counseled by their oncologist. It also would permit us to detect a difference in each scale of 3 or more between women who consulted a fertility specialist or preserved their fertility versus those who only received counseling from the oncology team.
Initially, Student t tests were used to compare the characteristics of responders and nonresponders. Multivariate logistic regression analyses were conducted as appropriate to determine the odds of counseling and fertility preservation.
Analyses of QOL included only women who reported treatment with potential to compromise fertility (ie, systemic chemotherapy, pelvic radiation, pelvic surgery, or bone marrow transplantation). T tests were used to compare QOL outcome scales between groups. First, we sought to examine the impact of receiving precancer treatment infertility counseling on QOL by comparing mean QOL scores of women who were and were not counseled by their oncology team. Second, we evaluated whether mean QOL scores were higher after consulting a fertility specialist or taking action to preserve fertility than after receiving counseling only from the oncology team. Decision regret scores were calculated only for women who had been counseled about fertility risks by an oncologist. Multivariate linear regression was used to examine differences in QOL first between women who did and did not receive oncology team counseling and then between those who preserved fertility or consulted a fertility specialist versus those who were counseled only by the oncology team, adjusting for the effect of disease type, age at diagnosis, and pretreatment parity.
Of the 2532 women who were contacted, 1378 women replied to our initial contact letter or survey. Of these, 337 refused to participate, and 1041 (41%) completed our survey. Forty-seven percent of participants completed it online, and 53% completed it on paper. Reasons for declining participation included a request to be removed from all cancer registry studies, no interest in further childbearing, the topic of infertility was too emotionally difficult to discuss, or the survey was too long. The average time to complete the survey was 26 minutes. Of the 1041 women who completed the survey, 918 reported treatment with the potential to compromise their fertility and were included in QOL analyses.
Table 1 compares the 1041 responders and 1491 nonresponders based on disease and demographic data in the cancer registry. Patients who completed the survey were 1.4 years younger at diagnosis than those who did not (P < .0001) and were diagnosed with more aggressive cancers, as indicated by a SEER summary stage index (range, from 0 [in situ] to 7 [metastatic]) of 3.7 versus 3.4 (P = .0008). There were no differences between responders and nonresponders in socioeconomic status (calculated from median income and education for the census block group of residence at diagnosis; P = .8) or years since diagnosis (P = .2).

The age and childbearing desires of the 918 participants who reported receiving treatment with potential to affect fertility are listed in Table 2. Patients with a history of breast and GI cancers tended to be the oldest at diagnosis and were the most likely to have had children before treatment. Depending on the type of cancer, between 47% and 63% of respondents reported desiring to have children after treatment, and the highest rates were observed among women with leukemia (59%) and Hodgkin disease (63%). These latter 2 groups also were composed of women with the youngest mean ages.

Prevalence of Counseling and Action
Of the 918 patients who reported receiving treatment with the potential to affect fertility, 560 (61%) were counseled about potential reproductive loss by a member of the oncology team. Overall, 46 of 918 women (5%) visited a fertility specialist, and 36 women (4%) took action to preserve their fertility. Eight women preserved embryos, 9 preserved eggs, 1 underwent an oophoropexy, and 18 used ovarian-suppression therapy under the care of a fertility specialist.
Of the 560 women who were counseled by their oncology team, 505 (90%) were only counseled by the oncology team and took no further action (ie, neither visited a fertility specialist nor preserved fertility). Forty women (7%) were counseled by the oncology team and went on visit a fertility specialist, and 30 women (5%) who received counseling from the oncology team went on to pursue fertility preservation. These latter 2 groups of women were used to examine the QOL impact of pursuing further counseling and fertility preservation beyond being counseled by the oncology team alone.
Odds of Pursuing Fertility Preservation
Of the 918 women who received treatment with potential to impact fertility, those who were aged <35 years at diagnosis were more likely to preserve their fertility than older women (odds ratio [OR], 11.0; 95% confidence interval [CI], 1.5-81.9). Women without children at diagnosis were more likely to take action to preserve their fertility than those with children (OR, 4.6; 95% CI, 1.6-13.5).
Satisfaction With Life Scale
We observed no significant differences in SWLS scores between women who were counseled about their risk of infertility by the oncology team compared with those who were not (20.2 vs 19.8; P = .57) (Table 3). However, there was a trend toward improved SWLS scores by as great as 3 points when women who were counseled by an oncology team also went on to consult a fertility specialist (23.0 vs 19.8; P = .09) (Table 4). This trend remained after controlling for cancer type as well as age and parity at diagnosis. Furthermore, women who were counseled by an oncologist and took action to preserve their fertility had an even greater improvement in SWLS scores than those who were counseled about infertility only by an oncologist (24.0 vs 19.8; P = .05).

Quality of Life
Women who had been counseled by their oncology team had slightly higher physical WHOQOL-BREF subscale scores compared with those who were not counseled, although this difference was no longer observed after adjusting for age, cancer type, and parity (16.3 vs 15.8; P = 0.12) (Table 3). Women who were counseled by an oncologist and visited a fertility specialist had significantly higher physical domain scores than women who were counseled by an oncologist but did not visit a fertility specialist (17.7 vs 16.2; P = .01) (Table 4), and this difference remained significant after adjustment for other potential confounders. Women who were counseled by an oncologist and who preserved their fertility also had significantly higher physical domain scores than women who received only infertility counseling by their oncologist (17.6 vs 16.2). This relation remained a trend after controlling for age, cancer type, and parity (P = .08).
In the domain of psychological health, a significant difference was noted only between women who had been counseled by their oncology team compared with those who had not (15.7 vs 15.3; P = .03) (Table 3), and this difference remained a trend after controlling for confounders (P = .08) (Table 3). Women who had consulted a fertility specialist (17.0 vs 16.3; P = .09) and those that had taken action to preserve their fertility (17.2 vs 16.3; P = .09) had trends toward higher environmental subscale scores versus those who were counseled about infertility by an oncologist but who did not do either of these things. Again, these trends remained regardless of age, cancer type, or parity at diagnosis. No statistically significant differences were noted in the social domain.
Receiving counseling from a fertility specialist and preserving fertility both appeared to decrease regret. Women who were counseled about their risk of infertility from cancer therapy by both an oncology team and a fertility specialist had significantly less regret about their decision to preserve fertility than those who were counseled only by an oncology team (DRS, 8.4 vs 11.0; P < .0001) (Table 4). Among those women who were counseled by their oncologist, the largest difference in regret was noted between women who took action to preserve their fertility and those who did not (DRS, 6.6 vs 11.0; P < .0001). These differences remained significant after adjustment for age at diagnosis, cancer type, and parity at diagnosis.
Receiving precancer-treatment counseling about reproductive loss significantly improved QOL after cancer treatment for reproductive-age women. Receiving precancer treatment counseling from a fertility specialist and attempting to preserve fertility were both associated with even greater improvements in QOL than being counseled by only the oncology team.
Satisfaction With Life Scale
Visiting a fertility specialist and preserving fertility were associated with improvements in overall satisfaction with life after cancer treatment. The differences noted in SWLS scales probably represent a clinically significant difference. The increases in SWLS between those who visit a fertility specialist or preserve fertility and those who do not are similar to differences in SWLS observed in other groups of young cancer survivors whose QOL has been affected by access to health care resources. For instance, it has been demonstrated that cancer survivors who reside in urban areas have higher satisfaction with life and lower levels of depression, anxiety, and distress than those in rural areas who have limited access to health services and resources.15 The increase in SWLS scores of 2 or 3 points between rural and urban survivors is very similar in magnitude to the increase between those who visit a fertility specialist or preserve fertility and those who do not. Being able to visit a fertility specialist or to preserve fertility before starting cancer treatment may have the same magnitude of impact on satisfaction with life for cancer survivors as moving from a relatively health care resource-poor rural area to a relatively resource-abundant urban setting.
Quality of Life
We also observed differences in several domains of the WHOQOL-BREF based on counseling history and whether action was taken to preserve fertility. Previous studies have indicated that a 1-point to 2-point difference in the raw score in each of the 4 domains of the WHOBREF-QOL represents a clinically significant difference in the domain score.16 Physical health was improved significantly in women who were counseled by a reproductive endocrinologist and in those women who took action to preserve their fertility, again supporting the notion that escalated fertility care, beyond only receiving counseling from an oncologist, is associated with improved QOL. These differences appear clinically significant and are similar in magnitude to the differences observed in women with gynecologic cancers who report pain and anemia versus those who do not.17
Although trends were observed suggesting positive differences in the environmental and psychological domains as a result of counseling, they do not appear as great in magnitude as the benefits to physical health and were not statistically significant. However, as others have pointed out, issues like infertility, the perceived safety (or lack thereof) of conceiving after treatment, the potential for delays in treatment to pursue fertility-preserving options, and changes in sexual functioning after treatment are complicated and impact many facets of psychological, social, and environmental health.15 Further research into the impact of reproductive loss after cancer treatment on particular facets of social, environmental, and psychological health is needed.
Counseling by a fertility specialist about reproductive loss before treatment reduces long-term regret about having or not having preserved fertility. Our patients reported greater differences in regret after pretreatment counseling by a fertility specialist than after being counseled by an oncologist alone, supporting the notion that pursuing escalated fertility care is likely to provide additional QOL benefits beyond discussing infertility with an oncology team. In previous studies, patients reported a preference for learning about potential reproductive loss from a focused visit with a fertility specialist.18 Regret is lessened further after taking action to preserve fertility. The magnitude of reduction in regret suggests that having the opportunity to take action to preserve fertility may add to the benefits gained from counseling.
The differences in regret probably are clinically significant. The 2-point to 5-point differences observed in DRS scores are similar to those cited as significant in other studies. For instance, DRS scores in men who chose more aggressive radiation treatment for prostate cancer was an average of 3 points less than men who opted out of such treatment.14
Rates of Counseling and Fertility Preservation
Thirty-nine percent of patients in our study did not recall being told about the risk of treatment to their fertility. This is consistent with counseling rates reported in other studies.4 An area for improvement in patient care may be implementing more frequent referral to reproductive health specialists. Although rates of referral to a fertility specialist (5%) in our study appear low, the rates are similar to those reported in other studies. For instance, in 2009, a survey of 249 oncologists at major academic centers in the United States reported that only 6% of oncologists always referred reproductive-age women for fertility preservation.19 Our rate of women taking action to preserve their fertility (4%) also is consistent with other published rates.20 We observed that 80% of the patients who visited a fertility specialist took action to preserve fertility. This is consistent with a previous retrospective case-control study, which indicates that approximately 67% of patients who are referred to a fertility specialist take action to preserve their fertility.21
Study Strengths and Limitations
This study has several important strengths and limitations. A significant proportion of the eligible participants in our study were not reached. However, the response rate was similar to that in several other registry-based studies of young women cancer survivors (range, 26%-51%).4, 10, 22, 23 In addition, given the importance of survivorship issues, the National Cancer Institute recently recommended the use of cancer registries as a means of conducting studies that could rapidly yield information about life after treatment.24, 25 Despite the benefits of registry-based studies, the possibility of sampling bias remains a concern in this study. Although women who responded were slightly younger at diagnosis than those who did not, there were no differences with regard to socioeconomic status. It is also likely that, given the consistency of our counseling and preservation rates with other studies, we achieved a relatively accurate sampling of the population with regard to previous exposure to fertility preservation. However, other important confounding factors that were not controlled for include the absence of information regarding current disease state (ie, recurrence or not) and residual side effects. Patients' disease may have recurred or they may have received the most aggressive treatment, which resulted in chronic toxicities—all of the above can contribute to reduced satisfaction with life and QOL.
It is difficult to predict exactly which women will choose to use fertility preservation in the future. However, with as few as 4% of eligible patients currently accessing the potential long-term benefit of fertility-preservation services, a primary focus of future research and policy decisions could be on continuing to improve access in an equitable manner. For instance, our study indicates that older women are less likely to preserve their fertility. However, women reported higher regret and lower QOL if they were not counseled or if they did not preserve fertility, regardless of their age. Gaps in access could lead to missed opportunities to intervene and potentially improve QOL for certain patients. Disparities in access to fertility preservation and counseling—based on ethnicity, education level, and sex identity—have been noted in other studies, suggesting that there are important areas upon which to focus efforts to improve care.26, 27
In conclusion, although counseling by the oncology team is paramount, incremental benefits were observed in regret, satisfaction with life, and physical domains of QOL as intervention was escalated from infertility counseling by oncologists toward taking action to preserve fertility. Women of reproductive age should be encouraged to discuss future childbearing goals and to learn about the risks of their cancer treatment to their fertility during pretreatment counseling with the oncology team. However, there is additional benefit to a precancer-treatment referral to a reproductive endocrinologist and access to the opportunity to preserve fertility. Thus, as advanced cancer treatments increasingly help to prolong life, there is a need to refer for fertility counseling services and fertility preservation, because it now appears that they offer a significant chance to improve QOL post-treatment for our patients.
