Donor KIR2DS1-mediated Decreased Relapse and Improved Survival, Depending on Remission Status at HLA-Haploidentical Transplantation with Post-transplantation Cyclophosphamide.
Biology of Blood and Marrow Transplantation(2020)
摘要
•Donor KIR2DS1 was associated with reduced risk of relapse after HLA-haploidentical allogeneic hematopoietic cell transplantation (allo-HCT) using post-transplantation cyclophosphamide (PT/Cy-haplo).•Donor KIR2DS1 was associated with improved overall survival with PT/Cy-haplo.•GVL effect via NK cell alloreactivity was exerted in CR, but not in non-CR.•Donor KIR genotyping and disease status should be assessed for donor selection.•Elucidating mechanisms involved could lead to novel strategies for relapse therapy.
