Postchemotherapy Resection of Residual Mass in Nonseminomatous Germ Cell Tumor.

The introduction of cisplatin-based chemotherapy has revolutionized the care of patients with disseminated testicular germ cell tumors. Although a majority are cured with chemotherapy alone, surgical resection continues to play a role because one-third will have residual mass after chemotherapy. In this article, we review the current indications for postchemotherapy resection in nonseminomatous germ cell tumors, including masses greater than 1 cm, resection after salvage chemotherapy, with elevated markers, after late relapse, and for growing teratoma syndrome. We also highlight technical considerations of this often-challenging surgery, including the need for adjunctive procedures, extraretroperitoneal resections, and modern techniques to minimize morbidity.
