A high frequency of hypogonadism has been reported in male patients with advanced cancer. The current study was performed to evaluate the association between low testosterone levels, symptom burden, and survival in male patients with cancer.
Of 131 consecutive male patients with cancer, 119 (91%) had an endocrine evaluation of total (TT), free (FT), and bioavailable testosterone (BT); high-sensitivity C-reactive protein (CRP); vitamin B12; thyroid-stimulating hormone; 25-hydroxy vitamin D; and cortisol levels when presenting with symptoms of fatigue and/or anorexia-cachexia. Symptoms were evaluated by the Edmonton Symptom Assessment Scale. The authors examined the correlation using the Spearman test and survival with the log-rank test and Cox regression analysis.
The median age of the patients was 64 years; the majority of patients were white (85 patients; 71%). The median TT level was 209 ng/dL (normal: ≥ 200 ng/dL), the median FT was 4.4 ng/dL (normal: ≥ 9 ng/dL), and the median BT was 22.0 ng/dL (normal: ≥ 61 ng/dL). Low TT, FT, and BT values were all associated with worse fatigue (P ≤ .04), poor Eastern Cooperative Oncology Group performance status (P ≤ .05), weight loss (P ≤ .01), and opioid use (P ≤ .005). Low TT and FT were associated with increased anxiety (P ≤ .04), a decreased feeling of well-being (P ≤ .04), and increased dyspnea (P ≤ .05), whereas low BT was only found to be associated with anorexia (P = .05). Decreased TT, FT, and BT values were all found to be significantly associated with elevated CRP and low albumin and hemoglobin. On multivariate analysis, decreased survival was associated with low TT (hazards ratio [HR], 1.66; P = .034), declining Eastern Cooperative Oncology Group performance status (HR, 1.55; P = .004), high CRP (HR, 3.28; P < .001), and decreased albumin (HR, 2.52; P < .001).
In male patients with cancer, low testosterone levels were associated with systemic inflammation, weight loss, increased symptom burden, and decreased survival.
