Abstract

In the present study, we evaluated the efficacy and safety of rituximab in combination with standard doxorubicin, bleomycin, vinblastine, and dacarbazine (RABVD) in patients with classical Hodgkin lymphoma (cHL). In this phase 2 study, patients with chemotherapy-naive, advanced-stage cHL were treated with rituximab 375 mg/m(2) weekly for 6 weeks and standard ABVD for 6 cycles. The primary outcome was event-free survival (EFS) at 5 years. Eighty-five patients were enrolled, of whom 78 were eligible. With a median follow-up duration of 68 months (range, 26-110), and based on an intent-to-treat analysis, the 5-year EFS and overall survival rates were 83% and 96%, respectively. The 5-year EFS for patients with stage III/IV cHL was 82%. Furthermore, the 5-year EFS for patients with an International Prognostic Score of 0-2 was 88% and for those with a score of > 2, it was 73%. The most frequent treatment-related grade 3 or 4 adverse events were neutropenia (23%), fatigue (9%), and nausea (8%). Our results demonstrate that the addition of rituximab to ABVD is safe and has a promising clinical activity in patients with advanced-stage cHL. These data are currently being confirmed in a multicenter randomized trial.
