Aim of this trial was to prove the advantage of one cycle of bleomycin, etoposide, and cisplatin (BEP) chemotherapy compared with RPLND in terms of recurrence. Patients and Methods Between 1996 and 2005, 382 patients were randomly assigned to receive either RPLND (n = 191) or one course of BEP (n = 191) after orchidectomy. The primary study end point was the rate of recurrence. The trial was powered to detect a 7% reduction (from 10% to 3%) of recurrence with chemotherapy compared with surgery. Results After a median follow-up of 4.7 years, two and 15 recurrences were observed in the intention-to-treat population with chemotherapy and surgery, respectively (P = .0011). The difference in the 2-year recurrence-free survival rate between chemotherapy (99.46%; 95% CI, 96.20% to 99.92%) and surgery (91.87%; 95% CI, 86.87% to 95.02%) was 7.59% (95% CI, 3.13% to 12.05%). The hazard ratio to experience a tumor recurrence with surgery as opposed to chemotherapy was 7.937 (95% CI, 1.808 to 34.48). Conclusion To our knowledge, this is the largest randomized trial investigating adjuvant treatment strategies in clinical stage I NSGCT, which showed the superiority of one course BEP over RPLND performed according to community standards to prevent recurrence. Although not standard treatment, one course of BEP is active in an unselected group of patients with clinical stage I disease and merits further investigation.
