[A retrospective analysis of 124 patients with multiple myeloma who received up-front autologous hematopoietic cell transplantation following triplet induction therapy].

The IFM/DFCI group reported that VRD induction followed by up-front autologous peripheral blood stem cell transplantation (ASCT) and maintenance therapy led to median PFS of 50 months, which established up-front ASCT as the standard of care even in the era of novel agents. We conducted a retrospective analysis on outcomes of patients who received triplet induction therapy followed by up-front ASCT at our institution. A total of 124 patients received ASCT between November 2016 and December 2021 at Japanese Red Cross Medical Center. Patient characteristics, treatment response before and after ASCT, and PFS and OS were retrospectively analyzed. VRD-based induction therapy was used for 94%. Among 118 evaluable patients, 116 (98%) received either consolidation and/or maintenance therapy. Best responses were ≥CR 77% and ≥VGPR 94%, respectively. Sixty-eight out of 104 patients achieved MRD-negativity by multiparameter FCM (<10-5). Five-year estimated PFS and OS were 54.7% and 80.2%, respectively. Age ≥65, high-risk cytogenetic abnormalities, and
