Chemotherapy for testicular cancer: current status of the National Cancer Institute Combined Modality Trial.

Twenty-five previously untreated patients with advanced testicular carcinoma were treated with a five-drug combination chemotherapy program containing cis-dichlorodiammineplatinum(II). This drug regimen was used as part of a trial testing the efficacy of cytoreductive surgery (15 patients) and in ten additional patients not eligible for the combined modality study. Eleven of 25 (44%) patients had a complete response and 11 of 25 (44%) patients had a partial response. Nine of 11 (82%) patients with minimal tumor burden upon initiation of chemotherapy had a complete response. With a median followup of 12+ months, none have relapsed. Complete remissions in patients with very advanced bulky disease were rare (two of 14 [14%] patients) and of short duration, with both patients relapsing. In addition to the usual hematologic toxicity, 14 of 25 (56%) patients developed hypomagnesemia and five of 25 (20%) patients developed systemic reactions to cis-dichlorodiammineplatinum(II) which prevented further drug administration.
