摘 要:目的:异基因造血干细胞移植(allo-HSCT)是治疗血液病的重要手段,然而仅1/4的患者可能找到HLA全相合的同胞供体。为扩大供者来源,本研究比较脐血移植(UCBT)、单倍体相合移植(haplo identical,hi-HSCT)、非全相合非亲缘供者移植(MMUDT)3种造血干细胞移植的特点。方法:回顾性分析了2010年1日至2012年6月共计93例造血干细胞移植的病历资料,其中UCBT组22例,hi-HSCT组42例,M M UDT组29例,比较3组造血重建、急性移植物抗宿主病(a GVHD)、复发率、生存时间。结果:UCBT、hi-HSCT、MMUDT 3组造血重建时间(ANC>1.0×109)分别是19、12、12 d,UCBT组粒细胞重建明显延迟(P<0.05);3组植入时间(STR>95%)分别是15、26、20d,hi-HSCT组植入时间相对较晚;3组植入失败率分别是26%、5%、3%,UCBT组植入失败率较高(P<0.05)。3组a GVHD发生率无统计学差异,分别是50%、57.1%、72.4%,3组Ⅲ-Ⅵa GVHD发生率亦无统计学差异,分别是27.3%、28.6%、17.2%;UCBT组的慢性移植物抗宿主病(c GVHD)发生率最低,3组分别是19%、45.5%、58.3%;3组移植后100 d内的移植相关死亡率(TRM)分别是23.8%、20%、11.1%;3组2年的总体生存率分别是79.9%、80.9%、88.0%。结论:UCBT组c GVHD发生率最低,但造血重建缓慢;hi-HSCT组尽管干细胞来源广泛并且可以支持后续细胞免疫治疗,但TRM较高;而较高的a GVHD及c GVHD发生率是MMUDT组需要解决的首要问题。Objective: One of the truly revolutionary advances in hematopoietic cell transplantation (HCT) is the increasingly successful use of alternative donors, as only 1/4 of patients who require an allogeneic hematopoietic cell transplant will have a HLA-matched sibling donor. Thereby, three alternative graft sources: umbilical cord blood (UCB), haploidentical (hi) related donor and mismatched unrelated donor hematopoietic cell transplantation (MMUDT) are available. This study was purposed to compare the characteristics of umbilical cord blood transplantation (UCBT), haplaidentical (hi) related donor hematopoieetic cell transplantation (hi-HSCT) and MMUDT. Methods: The clinical date of 93 patients with hematologic malignancies who received UCBT ( n = 22 ), hi-HSCT ( n = 42 ) and MMUDT ( n = 29), and the days of bematopoietic reconstration and engraftment, rate of acute graft-versus-host disease (GVHD), relapse rate, and overall survival (OS) were analysed. Results: The median days of hematopoietic reconstitution (WBC 〉 1. 0 x 109) among UCBT recipients were significantly longer than those among hi-HSCT/ MMUDT recipients, ( 19 in UCBT, 12 in hi-HSCT and 12 in MMUDT) ( P 〈 0.001 ), whereas the median days of full engraftment (STR 〉 95 % ) among hi-HSCT recipients were longer than those among UCBT/MMUDT recipients (26 in hi-HSCT, 15 in UCBT and 20 in MMUDT, P =0. 028), the implant failure rate of UCBT recipients was higher than others (26% in UCBT, 5% in hi-HSCT, 3% in MUUDT)(P 〈 0.05 ). Multivarite analysis demonstrated no apparent differences in the rate of aGVHD (50 % in UCBT, 57.1% in hi-HSCT and 72.4 % in MMUDT) ( P = 0.498 ), and the rate of Ⅲ-Ⅵ aGVHD also was no significant defference (27. 3% in UCBT, 28. 6% in hi-HSCT and 17. 2% in MMUDT) ( P = 0. 543), the rate of chronic GVHD of UCBT recipients was lowered ( 19.0% in UCBT, 45.5 % in hi- HSCT, 58.3% in MMUDT, P =0.026).
