Management of Stage II Germ Cell Tumors: Be Sure, Be Patient, Be Safe.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A healthy 27-year-old man discovered a left testicular mass. Several months later he saw an urologist, who palpated a suspicious mass on the left testicle; an ultrasound confirmed a 2-cm solid mass. Serum tumor marker testing disclosed a slightly elevated alpha-fetoprotein (AFP) of 12.3 µg/L (upper limit of normal, 8.0 µg/L), and a normal β-human chorionic gonadotropin (HCG). Staging imaging with a contrast-enhanced computed tomography (CT) scan of the chest/abdomen/pelvis showed no evidence for retroperitoneal lymphadenopathy or distant metastases. He underwent a left radical orchiectomy, and pathology showed a 1.5-cm mixed germ cell tumor with 85% embryonal, 10% yolk sac tumor, and 5% mature teratoma histologies. Lymphovascular invasion was present. His AFP normalized after surgery. After discussion of management alternatives, he chose active surveillance, but 4 months later a scheduled surveillance CT scan identified a 1.4-cm left para-aortic lymph node just below the left renal hilum ( Fig 1 ). Serum tumor markers remained negative. He returns to discuss his results and potential management options.
