    Abstract:
    PURPOSE: Standard chemotherapy for good prognosis metastatic nonseminomatous germ cell tumors of the testis currently includes etoposide and cisplatin. The optimal number of cycles and the need for bleomycin remain matters of debate. Three cycles of bleomycin, etoposide and cisplatin (BEP) or 4 cycles of etoposide and cisplatin are supposed to represent equivalent optimal regimens. MATERIALS AND METHODS: We analyzed the therapeutic outcome of 75 patients with good risk metastatic nonseminomatous germ cell tumor of the testis who were routinely treated at our institute. The chemotherapy regimens consisted of 4 cycles of BEP in 17 patients, 3 cycles of BEP in 23 patients, and 4 cycles of etoposide and cisplatin in 35 patients. RESULTS: All 75 patients achieved a complete or partial response with normal serum tumor markers. After a median followup of 3.5 years (range 2 to 7.5) the overall no evidence of disease rate was 91% (100, 96 and 83% in patients treated with 4 cycles of BEP, 3 cycles of BEP, and 4 cycles of etoposide and cisplatin, respectively). When considering the number of adverse events in each treatment group, that is the number of surgical complete responses or relapses after complete remission, results appeared similar with 3 or 4 cycles of BEP (2 and 3, respectively) but lower in patients who received 4 cycles of etoposide and cisplatin (11 adverse events). Of the 35 patients treated with etoposide and cisplatin 4 (11%) died of disease while only 1 of the 40 (3%) treated with BEP died of disease. CONCLUSIONS: Four cycles of etoposide and cisplatin could yield inferior results compared to 3 cycles of BEP in patients with good risk nonseminomatous germ cell tumor of the testis. Our results highlight the need for a randomized trial addressing the question of therapeutic equivalence between these 2 chemotherapy regimens.
