title: The role of surgery following chemotherapy in stage III germ cell neoplasms.
abstract: After curative chemotherapy 58 patients with metastatic germinal tumors and 2 with extragonadal germinal tumors underwent an operation either to confirm a clinical complete response or to remove a residual mass. Biomarker status was converted to negative in all patients. Retroperitoneal lymphadenectomy was done in 22 patients after a complete clinical response was achieved and in 23 after an apparent complete response was achieved except for a residual retroperitoneal mass. Thoracotomy was done for a residual mass in 13 patients, while 2 underwent bilateral thoracotomy. Scarring was found in 25 patients (42 per cent), teratoma in 14 (23 per cent) and active tumor in 17 (28 per cent). One patient with scarring and primary seminoma died of disseminated seminoma, while 1 with primary teratocarcinoma died of disseminated disease, for a false negative rate of 3 per cent. Four patients with a residual mass showed unexpected findings: 2 had granulomas in the lung, 1 had carcinoid of the lung and 1 had retroperitoneal neurofibroma. Thus, there was a 7 per cent incidence of a mass being other than scar, teratoma or residual tumor. There was 1 operative death and 10 deaths of tumor, for an 18 per cent death rate. Of the 17 patients with active tumor 9 responded to salvage chemotherapy with stable complete remission and a minimum followup of 18 months. In addition to the 60 patients the advanced disease in 10 was surgically debulked after failure of chemotherapy and this procedure was followed by salvage chemotherapy. All 10 patients died, with a median survival of 7 months. The lack of responsiveness to chemotherapy was not improved by incomplete removal of tumor.
