异基因造血干细胞移植治疗75例完全缓解期急性髓系白血病的疗效及预后分析

本研究评价异基因造血干细胞移植(allo-HSCT)治疗完全缓解期(CR)急性髓系白血病(AML)的疗效,并对预后相关因素进行分析。对2000年至2007年在我院进行allo-HSCT的75例CR期的AML患者进行回顾性研究。计算总体生存率(OS)、无病生存率(DFS),并对影响预后的各因素进行统计学分析。结果表明,3年OS及DFS分别为58.4%及53.9%,累积复发率及移植相关死亡率(TRM)分别为16.9%及29.9%。急性移植物抗宿主病(aGVHD)的总体发生率为59.6%,其中Ⅱ-Ⅳ度aGVHD发生率为18.7%。非亲缘HLA相合移植病例3年DFS为34.3%,低于亲缘HLA相合移植病例(60.0%,p=0.019);难治性白血病患者3年DFS为35.7%,低于对照组(非难治性白血病组)58.2%(p=0.048);发生重度aGVHD的病例及对照组3年DFS分别为35.7%及54.4%(p=0.059)。非亲缘HLA相合移植及发生重度aGVHD的病例TRM明显增高(p值分别为0.033和0.010)。多因素分析确认,与allo-HSCT预后相关的危险因素有:非亲缘HLA相合移植(p=0.049,RR=2.09,95%CI1.01-4.36)、难治性白血病(p=0.038,RR=2.33,95%CI1.05-5.20)及重度aGVHD(p=0.040,RR=2.33,95%CI1.04-5.20)。结论:Allo-HSCT是AML缓解后治疗的有效方法,TRM是移植治疗失败的主要原因。非亲缘HLA相合移植、难治性白血病、重度aGVHD是影响AML患者allo-HSCT预后的主要危险因素。

Allogeneic Stem Cell Transplantation for 75 cases of Acute Myeloid Leukemia in Complete Remission: Outcome and Prognostic Analysis

This study was purposed to evaluate the outcome of patients with acute myeloid leukemia(AML) who received allogeneic hematopoietic stem cell transplantation(allo-HSCT) in complete remission,and to study the prognostic factors.75 cases of AML in complete remission receiving allo-HSCT from January 2000 to December 2007 were retrospectively analyzed.Major end points of study included overall survival(OS),disease free survival(DFS),relapse rate and transplantation related mortality(TRM).The results showed that ...
