Advanced extragonadal germ-cell tumors. Successful treatment with combination chemotherapy.

Thirty-two patients with primary extragonadal germ-cell tumors were treated at Vanderbilt and Indiana University Hospitals during the period from 1967 to 1981. Thirty-one patients had far-advanced disease when treatment was begun. All patients received intensive cisplatin-containing combination chemotherapy regimens. Tumors remaining after chemotherapy were surgically removed when feasible. Of the 31 evaluable patients, 18 have been continuously disease-free after therapy, 21 patients had a complete remission; the remaining 10 had partial response. Eighty-nine percent of patients with complete remission remain free of disease after median follow-up of 30 months. No relapses occurred after 12 months of complete remission. Patients with partial response had a median survival of 9 months with no long-term survivors. Response rates and survival are similar to patients with advanced-stage testicular germ-cell tumors. Extragonadal germ-cell tumors are as curable as testicular germ-cell tumors when treated with intensive cisplatin-containing combination chemotherapy regimens, and surgical resection when necessary.
