Surgical management of germinal testis tumors other than seminoma is presented. Phase I consists of removal of the primary tumor; phase II, the surgical removal of retroperitoneal metastatic disease, and phase III, surgical management of chest metastasis. Seventy-two patients were explored with the intent of performing a simultaneous bilateral retroperitoneal lymphadenectomy. Each had a radical orchiectomy prior to exploration. Seven patients were found unresectable because of extensive disease above the renal pedicle and lymphadenectomy was not performed. The remaining 65 were found resectable and a transabdominal bilateral retroperitoneal lymphadenectomy was done. Of this number, 20, or 30%, had metastatic nodes. No other treatment was used. All had a 3-year follow-up and 53 were followed for 5 years or more. The 3-year survivals for stage I is 93%, and for stage II, 75%. Survivals of 5 or more years in stage I are 86% and in stage II, 70%. Thus, this experience with pathologic stage II cases clearly demonstrates the capability of surgery as a primary treatment to control 70% of patients with retroperitoneal lymph node metastases. This surgical technique is therfore recommended as primary therapy in stage I and II non-seminomatous geminal testis tumors.
