摘要

Treatment strategies for relapsed/refractory large B-cell lymphoma (R/R LBCL) have evolved rapidly, yet relationships between therapy selection and outcomes remain poorly defined. The LEO CReWE study evaluated disease characteristics, patterns of care, and outcomes in 1504 patients with R/R LBCL from 2002 to 2022. Of these, 64% received chemoimmunotherapy at second-line (2L). Autologous stem cell transplant (ASCT) and/or chimeric antigen receptor T-cell therapy (CAR-T) were planned at 2L for 984 patients (65%), with 471 (31%) ultimately receiving ASCT and 94 (6%) receiving CAR-T. Complete response (CR) rates at 2L ranged from 24% for lenalidomide-based regimens to 49% for CAR-T; salvage chemotherapy achieved a 44% CR rate overall and 60% among patients who eventually underwent ASCT. Median event-free and overall survival from 2L were 4.3 months and 18.3 months, respectively; survival improved in eras during which CAR-T was available. Patients intended for but unable to receive ASCT or CAR-T experienced poor outcomes comparable to those never intended for curative therapy at 2L. The LEO CReWE study represents the first large-scale depiction of 2L treatment patterns and outcomes for LBCL in the modern era, inclusive of all treatment approaches, and underscores the ongoing need for more effective therapies despite the advent of CAR-T.
