We report the long-term clinical outcomes of a retrospective multicenter study that enrolled 169 patients with multiple myeloma (MM) in first relapse after failing autologous stem cell transplantation (SCT). After HLA typing at relapse, 79 patients with a suitable donor, 72 (91%) of whom eventually underwent salvage allogeneic SCT (allo-SCT), were compared with 90 patients without a donor who were treated with multiple lines of salvage treatment with bortezomib and/or immunomodulatory agents. At a median follow-up of 30 months (range, 2-180 months) for all patients and 110 months (range, 38-180 months) for surviving patients, 7-year progression-free survival (PFS) was 18% in the donor group and 0% in the no-donor group (hazard ratio [HR], 2.495; 95% confidence interval [CI], 1.770-3.517; P?P?
