Key clinical point: The outcomes of autologous stem cell transplantation (ASCT) are not superior to those of anti-CD20 radioimmunotherapy, which offers a less toxic consolidation approach, in patients with relapsed or refractory (R/R) follicular lymphoma (FL) receiving rituximab-based induction and maintenance.
Major finding: At a 77-month median follow-up, both treatment groups had estimated 3-year progression-free survival rates of 62% (hazard ratio [HR] 1.11; P = .6662) and similar 3-year overall survival (HR 0.94; P = .8588). ASCT vs radioimmunotherapy led to higher rates of grade ≥ 3 hematological toxicity and grade ≥ 3 neutropenia (both P < .001).
Study details: This phase 3 FLAZ12 trial included 159 patients with R/R FL after ≤2 chemotherapy lines (≥1 lines containing rituximab) who received rituximab-based induction chemoimmunotherapy, with those showing a partial or complete response being randomized 1:1 to receive ASCT or radioimmunotherapy, both followed by rituximab maintenance.
Disclosures: This study was funded by the Agenzia Italiana del Farmaco (AIFA) and Fondazione Italiana Linfomi. Some authors declared receiving honoraria or research funding from AIFA and others.
