Rituximab/bendamustine (RB) and rituximab/ifosfamide/carboplatin/etoposide (R-ICE) are commonly used to treat relapsed/refractory diffuse large B-cell lymphoma (DLBCL), although their effectiveness has not been compared in real-world practice. This study evaluated data from DLBCL patients who relapsed after or were refractory to first-line therapy in an electronic health record (EHR)-derived database between 2011 and 2018. One hundred thirty-seven patients using RB and 270 patients using R-ICE were included for analysis. Transplantation after second-line therapy was considered a censored event in the time-to-event analyses. Patients in the RB group were older and had poorer performance status while there were no significant differences in stage, cell of origin, and double-/triple-hit subtypes. Relative to the R-ICE group, the RB group had significantly longer time-to-next-treatment (TTNT) and overall survival (OS). Subgroup analyses revealed that patients who were

Mantle cell lymphoma (MCL) is a B-cell lymphoma featuring an aggressive course and a progressive relapsing pattern. International guidelines recommend early consolidative autologous stem cell transplant (auto-SCT) for eligible patients while reserving allogeneic SCT (allo-SCT) as second-line therapy for refractory cases. Since data describing the implementation of transplants in the Asian population with MCL are limited, we aimed to analyze post-SCT outcomes of 99 MCL patients from the Taiwan Bone Marrow Transplant Registry database. The median age was 56 years, and 11% of the patients had blastoid variant MCL. Ninety-four patients received auto-SCT, while 13 patients received allo-SCT, eight of which received allo-SCT after failing auto-SCT. Before auto-SCT, 52% of the patients were in their first complete remission (CR1). Overall, 37 patients (39%) relapsed after auto-SCT. The median post-auto-SCT progression-free survival and overall survival (OS) were 43.6 months and not reached, respectively. Blastoid variant MCL, transplant not received in CR1, and disease progression within 12 months post-auto-SCT independently predicted inferior OS in multivariate analysis. The median post-allo-SCT OS was 74 months. Two patients (15%) died of MCL recurrence post-allo-SCT. Three patients with refractory diseases were salvaged with ibrutinib or venetoclax to allo-SCT. Treatment strategies incorporating novel agents warrant further optimization.
