An alternative treatment regimen of advanced seminoma with carboplatin, etoposide, and bleomycin instead of cisplatin-based therapy

AbstractBackground tin-based therapy is associated with acute and late toxicities. Therefore, a potentially less toxic carboplatin-based regimen was evaluated in patients with advanced seminoma. ts and methods en patients with advanced seminoma were treated on outpatient basis with carboplatin (AUC5) at day 1, etoposide (100 mgm-2) at days 1–5, and bleomycin (30 IU) at day 2 (CEB). Treatment was 3-weekly for a total of 4 cycles. Outcome and toxicities were analyzed. s follow-up was 4 years and 7.5 months. Five-year progression-free survival was 86.6% (95% confidence interval (CI), 70.6%–100%), 5-year overall survival 100%, and 10-year overall survival 85% (95% CI, 63.3%–100%); 39% of all patients reached complete remission. Two patients underwent adjuvant treatment. Two patients relapsed; 1 is in ongoing remission 4 years after salvage therapy, the other died almost 6 years after CEB-therapy, despite multiple lines of salvage therapy. The main acute toxicity observed was hematologic. No late cardiovascular events or secondary malignancies were noted. sion eatment is effective in advanced seminoma, showing minor toxicity. Progression-free and overall survival rates at 5 and 10 years are comparable to those achieved with cisplatin-based therapy. This indicates that carboplatin-combination therapy might be a good alternative to cisplatin-based therapy in the treatment of advanced seminomas.
