We analyze the outcomes of T cell–replete haploidentical transplantation in adult patients with acute myeloid leukemia.
Host-versus-graft killer cell immunoglobulin–like receptor (KIR) ligand mismatched hematopoietic stem cell transplantation was associated with a higher relapse rate
Bidirectional KIR ligand–matched hematopoietic stem cell transplantation showed relatively favorable outcome.
The KIR ligand effect was significant in patients in first complete remission at hematopoietic stem cell transplantation.
