摘要 目的 分析单倍体造血干细胞联合第三方脐血输注治疗白血病的疗效及安全性.方法 对苏州大学附属第一医院2011年1月至2012年5月44例采用单倍体造血干细胞联合第三方脐血输注治疗的白血病患者进行回顾性分析,其中急性淋巴细胞白血病(ALL) 16例、急性髓系白血病(AML)24例、慢性粒细胞白血病(CML)3例、T淋巴母细胞淋巴瘤1例.结果 44例白血病患者回输的单倍体供体移植物中CD34+细胞中位数为3.14×106/kg(1.68×106/kg ~ 8.32× 106/kg),回输的第三方脐血中CD34+细胞中位数为1.03×105/kg(0.31×105/kg~5.32×105/kg).42例(95.45%)患者造血重建,中性粒细胞造血重建时间为14d(10~29 d),血小板造血重建时间为23d(11~89d).对42例植入成功的患者长期监测供受体嵌合率(STR),除5例(11.90%)患者在移植后3~13个月复发,其余37例(88.10%)患者STR均≥95%.17例(40.47%)患者发生不同程度的急性移植物抗宿主病(aGVHD),发生Ⅱ~Ⅳ度aGVHD的患者共8例(19.05%),发生Ⅲ~Ⅳ度aGVHD的患者为4例(9.52%).23例(54.76%)发生慢性移植物抗宿主病(cGVHD),其中局限型17例(40.47%),广泛型6例(14.29%).1年总生存(OS)率为70.84%,1年无事件生存(EFS)率为63.34%.结论 初步研究证实单倍体造血于细胞联合第三方脐血输注治疗白血病安全有效,从而为异基因造血干细胞的移植提供了新的方法. Objective To analysis the effectivity and safety of haploidentical stem cell transplantion combined with unrelated cord blood infusion in the treatment of leukemia.Methods 44 patients were treated by haploidentical stem cell transplantion combined with unrelated cord blood infusion from January 2011 to May 2012,including 16 cases of acute lymphoblastic leukemia (ALL),24 cases of acute myeloid leukemia (AML),3 cases of chronic myeloid leukemia (CML) and 1 case of T lymphoblastic lymphoma.Results The median number of CD34+ cells was 3.14×106/kg (1.68×106/kg-8.32×106/kg) in the haploidentical grafts and 1.03×105/kg (0.31×105/kg-5.32×105/kg) in the cord blood units.42 (95.45 %) patients acquired hematopoietic reconstruction.The median time was 14 d (10-29 d) for neutrophil engraftment and 23 d (11-89 d) for platelet engraftment.42 patients were on long-term monitoring for STR,except 5 (11.90 %) patients relapsed in 3-13 months after transplantation,STR of other 37 (88.10 %) patients were all higher than 95 %.17 (40.47 %) patients experienced acute graft-versus-host disease (aGVHD),the degree was Ⅱ-Ⅳ in 8 patients (19.05 %),and Ⅲ-Ⅳ in 4 patients (9.52 %).23 (54.76 %) patients had chronic graft-versus-host disease (cGVHD),including 17 (40.47 %) cases of localized type and 6 (14.29 %) cases of diffuse type.The one year overall survival (OS) rate was 70.84 % and event-free survival (EFS) rate was 63.34 %.Conclusion Haploidentical stem cell transplantion combined with an unrelated cord blood infusion is safe and effective in the treatment of leukemia,which may provide a new approach to allogeneic hematopoietic stem cell transplantation.
