Matched unrelated vs haploidentical donor hematopoietic cell transplantation using posttransplant cyclophosphamide.

Abstract

Posttransplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis is now standard for matched unrelated donor (MUD) hematopoietic cell transplantation (HCT). Previous studies comparing MUD and haploidentical donor HCT using PTCy were limited in size and follow-up. We therefore performed a registry-based analysis examining the impact of donor type on HCT with PTCy. Adult patients (n = 5873) receiving MUD (n = 1973) or haploidentical (n = 3900) HCT with PTCy for acute leukemia (74.2%) or myelodysplastic syndrome (MDS; 25.8%) reported to the Center for International Blood and Marrow Transplant Research between 2017 and 2021 were included. Primary end points were 3-year overall survival (OS) and GVHD-free, relapse-free survival (GRFS). Cox regression an
