Donor KIR Genotype Impacts on Clinical Outcome after T Cell –Depleted HLA Matched Related Allogeneic Transplantation for High-Risk Pediatric Leukemia Patients

Allogeneic hematopoietic stem cell transplantation (HSCT) has a major role in the treatment of high-risk and relapse acute myelogenous leukemia (AML) and high-risk acute lymphoblastic leukemia, the most important causes of death in children with cancer. [1,2] The best overall survival (OS) and relapse-free survival of this procedure were observed in matched related donors (MRDs), only possible in less than one-third of patients. [3 –5] Recent reports revealed that even with a HLA match, 20% to 40% of patients develop graft-versus-host disease (GVHD).
