Current outstanding challenges in germ cell tumors.

PURPOSE OF REVIEW:Despite the remarkable advances in the treatment of germ cell tumors (GCT), several challenges remain. This review aims to highlight some of these challenges and provide guidance on how to navigate through them. RECENT FINDINGS:Patients with International Germ Cell Cancer Collaborative Group poor risk disease have worse prognosis and investigating novel therapeutic interventions are warranted in this population. Patients with brain metastases require a multidisciplinary approach by a group of clinicians experienced in the management of germ cell tumors. Patients with platinum refractory disease have poor prognosis and development of novel treatment options is urgently needed. Conventional tumor markers including alpha fetoprotein and human chorionic gonadotropin remain standard. Development of novel biomarkers to detect minimal residual disease or teratoma is needed. SUMMARY:Management of patients with GCT requires a multidisciplinary approach. Patients should preferably be evaluated at tertiary care centers with expertise in the management of this disease.
