Abstract

We evaluated 79 patients with multiple myeloma (MM) =70 years referred to our blood and marrow transplant clinic, within 1 year of diagnosis from 2010 to 2019, for consideration of autologous stem cell transplant (ASCT). Thirty-eight (48%) of 79 patients underwent ASCT. ASCT was not pursued in 41 (52%) patients due to: patient or physician preference in 80% (n?=?33) or ineligibility in 20% (n?=?8). Baseline characteristics of patients in the two groups were similar. Median PFS from treatment start amongst patients undergoing ASCT (n?=?38) vs. not (n?=?41) was 41 months vs. 33 months, p?=?0.03. There was no difference in OS, with estimated 5-year OS of 73% vs. 83%, respectively (p?=?0.86). Day +100 transplant-related mortality (TRM) was 0%. ASCT was an independent favorable prognostic factor for PFS in multivariate analysis, after accounting for HCT-CI score, performance status, hematologic response, and maintenance. Finally, patients =70 years undergoing ASCT had similar PFS compared to a contemporaneous institutional cohort of patients <70 years (n?=?631) (median PFS from transplant: 36 vs. 47 months, p?=?0.25). In this retrospective analysis, ASCT was associated with low TRM and better PFS in fit older adults with MM compared to non-transplant therapy, with comparable benefits as seen in younger patients.
