Considerations for haploidentical versus unrelated donor transplants.

Haploidentical transplantation is increasingly performed worldwide due to novel methods to control alloreactivity between the donor and recipient. This major advancement has increased donor availability to almost all patients in need. Outcomes with haploidenitcal donors have also improved and prompted many groups to compare outcomes between haploidentical and HLA-matched donor transplants. In this review, we provide a summary of available data on haploidentical transplants performed with post transplant cyclophosphamide-based graft-versus-host disease (GVHD) prophylaxis and HLA-matched unrelated donor transplants.
