ObjectivesTo describe the clinical characteristics and outcome of patients with metastatic nonseminomatous germ cell tumor requiring reoperative retroperitoneal surgery at the Memorial Sloan-Kettering Cancer Center, because such patients are poorly characterized.MethodsThe Memorial Sloan-Kettering Cancer Center germ cell tumor surgical database was reviewed from January 1989 through April 2001, and the clinical characteristics of patients undergoing reoperative retroperitoneal surgery for nonseminomatous germ cell tumor were identified. The initial presentation, histologic findings, morbidity, and survival were analyzed. Disease-specific survival was calculated using the Kaplan-Meier method.ResultsA total of 56 patients underwent 61 repeat operations: 22 after primary retroperitoneal lymph node dissection (RPLND) and 34 after postchemotherapy RPLND. Left testicular primary tumors were more common than right (33 versus 23), and the most common sites of disease prompting reoperation were the para-aortic and left hilar regions. Teratoma was the most common histologic finding at the time of reoperation. Of 56 patients, 37 (66%) required chemotherapy between the initial operation and reoperation. The overall perioperative complication rate was 27%, and median length of hospital stay was 8 days. Sixty-nine percent of patients required adjunctive procedures at the time of reoperation, the most common of which was thoracotomy. The 5-year disease-specific survival rate was 67% for the entire group (86% following reoperation after primary RPLND and 56% following reoperation after postchemotherapy RPLND).ConclusionsReoperative retroperitoneal surgery for nonseminomatous germ cell tumor can be performed with acceptable morbidity in select referral centers. Teratoma is highly prevalent in the retroperitoneum at the time of reoperation. A significant subset of these high-risk patients can be salvaged with complete resection.
