Is gynecomastia related to the disease characteristics and prognosis in testicular germ cell tumor patients?

PURPOSE We aimed to assess the relationship between gynecomastia and tumor markers, histologic sub-types, and prognosis in patients with testicular germ cell tumors. METHODS This study included 73 testicular germ cell cancer patients with pretreatment chest, abdomen and pelvis computed tomography CCT) scans and tumor markers (beta-human chorionic gonadotropin (beta-hCG], lactate dehydrogenase [LDH], alpha-fetoprotein [AFP]). The volumetric analysis of the breast glandular tissue, the presence of gynecomastia and metastatic disease were determined using CT scans. Patients were classified according to the International Germ Cell Cancer Collaborative Group (IGCCCG) prognostic classification. The association between gynecomastia, breast glandular tissue volume, tumor markers, metastatic disease, and disease prognosis were evaluated. RESULTS Thirty-four of the patients (46.6%) had gynecomastia. A breast volume cutoff value of 0.78 cm' to diagnose gynecomastia led to 85% sensitivity and 95% specificity. Serum 13-KG level correlated with the breast glandular tissue volume weakly (r=0.242, P = 0.039). Gynecomastia was more common in patients with elevated (3-hCG levels (P = 0.047), and was not associated with pulmonary, nonpulmonary distant, or nodal metastases (P = 0.378, P = 0.884, P = 0.333, respectively). No significant association was found between the disease prognosis and gynecomastia (P = 0.556). CONCLUSION Gynecomastia was common among testicular germ cell cancer patients with elevated beta-hCG. However, it was not associated with metastatic disease and prognosis.
