[VM-26 and VP-16 salvage therapy for refractory germinal testicular cancers].

Thirteen evaluable patients with germinal testicular cancers failing to be cured with first-line therapy (refractory) were treated by salvage chemotherapy. Ten patients received salvage chemotherapy with VM-26 (50 mg/m2, twice a week X 6 weeks) and cisplatin (CDDP, 20 mg/m2 for 5 consecutive days every 3 weeks for 3-4 times) (P-VM), 3 patients were also treated by radiation therapy, and 3 patients received VP-16 (100 mg/m2) and CDDP (20 mg/m2) (P-VP), all given daily for 5 consecutive days every 3-4 weeks for 4-5 courses. Of 13 evaluable patients, 6 (46%) had complete response (CR) (three cases were also treated with radiation therapy), 4 (31%) achieved partial response (PR), and 3 (23%) had no response. Limited to 7 patients treated with only P-VM therapy, there were 3 (43%) CR and 4 (57%) PR. Nine patients (69%) remained alive and were continuously disease free 18 to 84 months (median 48 months). Hematologic toxicity was severe, but with no death related to sepsis. Salvage chemotherapy with VM-26 or VP-16 and cisplatin offers potentially curative treatment to patients with refractory testicular cancer. The addition of radiation therapy to salvage chemotherapy was also effective.
