RESUMEN
We experienced the VNCOP-B (etoposide, mitoxantrone, cyclophosphamide, vincristine, predonisolone, bleomycin) combination regimen for the treatment of elderly patients with aggressive non-Hodgkin lymphoma (NHL) in a multicenter study by 6 collaborative institutions. Patients were previously untreated > or = 60 years of age and received prophylactic G-CSF. Twenty patients entered this trial, and all of them were evaluated for feasibility, toxicity, and efficacy. The complete remission rate was 75.0%, with a 100% overall response rate; overall survival (OS) rate at 3 years was 79.1% (median follow up 761.5 days), with a 60.7% progression-free 3-year survival (PFS) rate (median follow-up 600.0 days). Our trial was promising and well-tolerated. According to IPI, high/high-intermediate risk was associated with significantly worse OS and PFS than low/low-intermediate risk (2-year OS: 51.8% versus 100.0%, p=0.0118; 2-year PFS: 33.3% versus 80.0%, p=0.0125). Grade 3/4 infections occurred in 3 patients, but no patients experienced it with predonisolone reduced.
