Transplant outcomes using older matched sibling donors compared with young alternative donors: a CIBMTR analysis.

ABSTRACT:

Abstract

Whether older HLA-matched sibling donors (MSD) are preferred over younger alternative donors for allogeneic hematopoietic cell transplantation (allo-HCT) with posttransplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis is unclear. We compared outcomes in allo-HCT recipients ≥50 years old after HCT from an older MSD (≥50 years) with recipients of younger (≤35 years) HLA-matched unrelated donor (MUD), haploidentical related donor (haplo), and HLA-mismatched unrelated donor (MMUD), grouped based on PTCy or calcineurin-inhibitor (CNI) based GVHD prophylaxis, that were reported to the Center for International Blood and Marrow Transplant Research between 2014 and 2021. The primary end point was overall survival (OS). Among 14 662 HCT recipients, 374
