1298 CHEMOTHERAPY IN EARLY STAGE TESTICULAR CANCER combination. Four cycles provided results equivalent to those obtained with 3 cycles.14 The subsequent trial of patients treated with 3 cycles of EP with or without bleomycin demon- strated a sigmficant increase in the number of treatment fail- ures on the EP m.15 Another theoretical approach to achieve a substantial decrease in the toxicity of chemotherapy is the use of carboplatin instead of cisplatin. However, 2 randomized stud- ies demonstrated inferior results with carboplatin compared to cisplatin.I6, 17 Consequently, omitting bleomycin in patients re- ceiving 4 cycles of EP and limiting the cumulative dose of bleomycin to 3 cycles of BEP represent 2 equivalent optimal alternatives for patients who receive primary chemotherapy for biological disease.1s I t is noteworthy that the 2 patients with active relapse had been primarily treated with either the VAB-6 or EC regimen and, therefore, they had not received optimal chemotherapy. CONCLUSIONS Primary chemotherapy yields excellent long-term results in patients with elevated serum tumor markers only after orchi- ectomy. Since results with primary retroperitoneal lymph node dissection suggest that elevated serum tumor markers usually reflect systemic metastases rather than retroperitoneal disease, primary chemotherapy using optimal regimens seems to be the most appropriate strategy to consider.
