Key clinical point: The rituximab, bendamustine, and low-dose cytarabine (R-BAC) regimen, not succeeded by maintenance therapy, induces long-term responses in previously untreated elderly patients with mantle cell lymphoma (MCL).
Major finding: After a median follow-up of 86 months, the median overall survival (OS) and progression-free survival (PFS) were not reached; the 7-year PFS and OS rates were 55% (95% CI 41%-67%) and 63% (95% CI 49%-74%), respectively. The 7-year duration of response rate among the 52 responding patients was 59% (95% CI 44%-71%). No signal of late toxicity was reported.
Study details: Findings are from a long-term analysis of the FIL-RBAC500 trial that included 57 previously untreated elderly patients with MCL who received the R-BAC regimen.
