PTCy-based graft-versus-host disease prophylaxis for matched sibling donor allogeneic hematopoietic cell transplantation.

Abstract

Posttransplant cyclophosphamide (PTCy) is a promising graft-versus-host disease (GVHD) prophylaxis in haploidentical and matched unrelated donor hematopoietic stem cell transplantation (HSCT), but its role in matched sibling donor (MSD) transplants remains unclear. We conducted a retrospective study of 413 MSD-HSCT patients receiving peripheral blood stem cell (PBSC) grafts from January 2010 to January 2023. Patients were categorized into 4 groups: group I (calcineurin inhibitor [CNI] + methotrexate [MTX] or mycophenolate mofetil [MMF]), group II (CNI + MTX or MMF + antithymocyte globulin [ATG]), group III (PTCy + ATG + CNI), and group IV (PTCy + CNI + MMF). PTCy was associated with a significant reduction in grade 2- 4 and grade 3-4 acute GVHD and moderate-to-severe chron
