Multicenter Study
Multicenter phase II study of bendamustine for relapsed or refractory indolent B-cell non-Hodgkin lymphoma and mantle cell lymphoma.
Bendamustine is a unique cytotoxic agent that has demonstrated efficacy in the treatment of indolent B-cell non-Hodgkin lymphomas (B-NHLs). In this multicenter phase II trial, the efficacy and safety of bendamustine were evaluated in Japanese patients with relapsed or refractory indolent B-NHL or mantle-cell lymphoma (MCL). Patients received bendamustine (120 mg/m(2) ) on days 1-2 of a 21-day cycle, for up to six cycles. ⋯ Reversible myelosuppression, including grade 3/4 leukopenia (65%) and neutropenia (72%), was the most clinically significant toxicity observed. Common non-hematologic toxicities included mild gastrointestinal events and fatigue. These results demonstrate the high efficacy and tolerability of single-agent bendamustine in relapsed patients with indolent B-NHL or MCL histologies.
