摘要
目的探讨HLA相合同胞供者异基因造血干细胞移植(allo-HSCT)治疗慢性粒细胞白血病(CML)的疗效及预后因素。方法35例CML患者,11例行HLA相合同胞供者异基因骨髓移植(allo-BMT),24例行异基因外周血干细胞移植(allo-PBSCT)。全身照射(TBI)+环磷酰胺(CY)方案预处理8例,白消安(BU)+CY方案预处理27例。结果造血重建34例(97．1％),3年无病生存率(DFS)为60．0％,5年累积生存率为57．1％。复发2例,移植相关死亡12例。并发症包括出血性膀胱炎(HC)5例,肝静脉闭塞病(HVOD)1例,急性移植物抗宿主病(GVHD)18例,慢性GVHD 17例。单因素分析显示,年龄≤30岁、慢性期移植、Ⅰ和Ⅱ度急性GVHD患者3年DFS分别高于年龄>30岁、加速期移植及Ⅲ和Ⅳ度急性GVHD患者。多因素Cox回归分析结果表明,年龄、疾病状态、急性GVHD的严重程度是allo-HSCT患者长期生存的独立影响因素。结论年龄≤30岁、慢性期、轻度GVHD的CML患者行allo-HSCT治疗,可获得较高的长期生存率。
Objective To retrospectively analyze the curative effects and prognostic factors of HLA-matched sibling donor allogeneic hematopoietic stem cell transplantation （allo-HSCT） for chronic myelogenous leukemia patients （CML）. Methods Of the 35 CML patients, 26 were males and 9 were females, with a median age of 32 （12 -50） years. 30 patients were in chronic phase of CML, 5 patients were in accelerated phase. Allo-HSCT from HLA identical siblings was performed for 35 patients, of whom 11 received bone marrow transplantation （BMT） and 24 peripheral blood stem cell transplantation （PBSCT）. Conditioning regimens was TBI （total-body irradiation） ＋ CY （CTX） protocol in 8 patients and BU/CY protocol in 27 patients. The average follow-up was 48 months （ range 7 - 108 months）. Results 34 （97. 1% ） patients were successfully engrafted, Among them, 21 patients （60. 0%） had three years disease-free （DFS） survival, The overall 5-year survival （OS） was 57. 1%, Two patients （5, 7% ） relapsed, Transplant-related mortality occurred in 12 patients, Hemorrhagic cystitis （ HC ） occurred in 5 patients and HVOD was observed in 1 patient, Acute graft-versus-host disease （aGVHD） occurred in 18 patients （51,4%）, among them 7 patients （20. 0% ） were of grade Ⅲ-Ⅳ, Chronic GVHD was in 17patients （48.5%）, There was no significant difference in 3-years DFS between BMT group and PBSCT group （54, 5% vs, 62.5% ,P 〉 0, 05 ）, The 3-year disease-free survival（DFS） was 42, 9% in TBI/CY group and 55.6% in BU/CY group （P 〉 0, 05 ）, In univariate prognostic analysis model, the DFS at 3 years is 75% and 47, 4% for ≤30 years patients and 〉 30 years patients, respectively, P 〈 0, 05, The 3-year DFS of patients with first chronic phase is higher than patients with advanced diseases （61, 3% vs, 40% , P 〈0, 05 ）, The 3-year DFS in patients of grade Ⅰ - Ⅱ GVHD was higher than that in patients of grade m-IV GVHD （81,8% vs. 14, 3% ,P 〈0, 05）.
