To evaluate the efficacy and safety of a combined regimen of bendamustine (B) and rituximab (R) in Japanese patients with relapsed/refractory (r/r) indolent B-cell non-Hodgkin lymphomas (B-NHLs) and mantle cell lymphoma (MCL). Patients aged 20-79 years with pathologically confirmed B-NHLs or MCL, which were r/r after 1-2 R-containing regimens, were included in this study. The BR regimen consisted of B (90 mg/m(2)) for two consecutive days and R (375 mg/m(2)) on day 1, 2, or 3. ⋯ There were no grade 5 toxicities. The BR regimen is safe in Japanese patients with r/r indolent B-NHLs and MCL, and is effective for those with r/r indolent B-NHLs. For the evaluation of late toxicity, especially infection, longer follow-up of this cohort is needed.
