Cisplatin, etoposide and bleomycin infusion (PEBi regimen) in good-risk patients with germ cell tumors.

Patients with good-risk germ cell tumors have an approximately 85-95% chance of cure with standard chemotherapy. However, acute and late toxicity may be severe and negatively influence the quality of life. In an attempt to reduce toxicity, we evaluated a new schedule including bleomycin administered-as a continuous infusion in patients with low and intermediate volume metastatic disease. Patients were treated as follows: cisplatin, 100 mg/m(2) day 4; etoposide, 100 mg/m(2) days 1 through 5; bleomycin, 15 unit bolus on day 1 followed by 30 mg as a continuous infusion for 72 h, with cycles repeated every 21 days. Between 1992 and 1996, 25 patients entered the study and were assessable for response and side effects. Major patient characteristics were: performance status ECOG 0-1; minimal disease, 13 patients, intermediate disease, 12; median age, 33 years (range 15-50). Twenty-one of 25 patients (84%) achieved a complete remission, 2 patients achieved a partial remission, and 2 patients did not respond to the regimen. At a median follow-up of 24 months, 24/25 patients were alive, 23 were without evidence of disease, and I had persistent disease. Grade III/IV side effects included leuko/neutropenia (8 patients), anemia (3 patients), and nausea/vomiting (3 patients). No drug-related deaths were observed, and no evidence of pulmonary toxicity was registered. In conclusion, the PEBi regimen is an effective and well-tolerated regimen in patients with good-risk germ cell tumors and may be considered as a front-line chemotherapy.
