HLA单倍型相合造血干细胞移植(human leukocyte antigen-haploidentical hematopoietic stem cell transplantation,HLA-haplo HSCT)是大多数血液病患者可选择的一种移植方式,能够节约寻找供者的时间和花费[1-2]。二十多年以来,多种单倍型相合移植方式,包括保留或去除T细胞的单倍型移植显示出了较好的预后[3-4]。多个移植中心报道,
Human leukocyte antigen( HLA)-haploidentical hematopoietic stem cell transplantation( HLA-haplo HSCT) without T-cell depletion has tremendously progressed over the past 20 years. Advances in graft manipulation, conditioning regimens, and pharmacological graft-versus-host disease( GVHD)prophylaxis have reduced the risk of fatal graft failure and severe GVHD. Donor-specific anti-HLA antibodies( DSA) negative status and killer immunoglobulin-like receptor( KIR) mismatch play potential roles in reducing the risk of graft failure and GVHD following HLA-haplo HSCT. New strategies to improve HLA-haplo HSCT outcomes include donor lymphocyte,selected T-cell subset and NK cell infusion,mesenchymal stem cell( MSC) co-transplantation and interleukin-2 application. Future challenges remain in improving posttransplant immune reconstitution and finding the best approach to reduce the incidence and severity of GVHD while simultaneously preserving the graft-versus leukemia effect to prevent the recurrence of underlying malignancy.
