摘  要:目的评价异基因造血干细胞移植(allo-HSCT)治疗难治/复发急性髓系白血病(AML)的疗效,并对预后相关因素进行分析。方法回顾性分析allo.HSCT治疗99例难治/复发AML患者总体生存(os)率、无病生存(DFS)率、移植物抗宿主病(GVHD)发生率、移植相关死亡率(TRM)及复发率,并分析影响预后的危险因素。结果全部99例患者中男59例,女40例,中位年龄为35(6~58)岁,均接受清髓性预处理。所有患者中性粒细胞均达植入标准,中位植活时间为14(9~25)d。移植后100dⅡ~Ⅳ度急性GVHD累积发生率为27.3%(95%CI18.9%~36.3%);2年慢性GVHD累积发生率为33.9%(95%CI24.6%~43.5%),其中广泛型慢性GVHD累积发生率为9_3%(95%CI4.5%-16.1%)。移植后3年OS、DFS、TRM率分别为45.0%(95%CI34.6%~55.4%)、45.0%(95%CI34.8%~55.2%)、19.7%(95%a12.4%~28.3%),复发率为36.6%(95%C126.9%~46.4%)。多因素分析显示.影响OS的独立危险因素包括移植前未缓解[P:0.009,HR=2.21(95%CI1.22~4.04)]、初诊WBC〉50×10^9/L[P=0.024,HR=2.11(95%CI1.11~4.02)]、供者年龄〉35岁[P=0.031,HR=1.96(95%CI1.06~3.60)]、移植后未发生慢性GVHD[P=0.008,HR:0.38(95%CI0.18—0.78)]。根据移植前危险因素(移植前未缓解、初诊WBC〉50x107L、供者年龄〉35岁)进行危险度分组,具有0、1、2~3个危险因素患者的3年OS率分别为75.0%、46.9%、15.4%(x^2=26.873,P〈0.001)。结论allo-HSCT是挽救性治疗难治/复发AML的有效手段,复发是影响生存的主要原因。移植前缓解状态、发病时WBC水平、供者年龄及移植后是否发生慢性GVHD是难治/复发AML患者allo—HSCT预后的独立影响因素。Objective To evaluate the outcomes and prognostic factors of patients with refractory and relapsed acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods The overall survival (OS), disease free survival (DFS), acute and chronic graft-versus-host disease (GVHD), relapse rate (RR), transplantation related mortality (TRM) and their related risk factors were analyzed retrospectively. Results All the patients (median age 35 years, range 6 to 58) received myeloablative conditioning regimens. All patients had successful engraftment, and the median time of neutrophils engraftment was 14 days (range 9 to 25). Of the patients who survived more than 100 days, the accumulative incidence of grade II- IV acute GVttD and chronic GVHD (cGVHD) were 27.3% (95% CI 18.9%-36.3% ), 33.9% (95% CI 24.6%-43.5% ), respectively. Meanwhile, the accumulative incidence of extensive cGVHD was 9.3% (95%CI 4.5%-16.1% ). The 3-year OS, DFS, RR, and TRM was 45.0% (95%CI 34.6%-55.4%), 45.0%(95%CI 34.8%-55.2%), 36.6%(95% C1 26.9%- 46.4% ) and 19.7% (95% CI 12.4%- 28.3% ) respectively. Multivariate analysis revealed four independent risk factors: non remission status before transplantation [P= 0.009, HR = 2.21 (95%CI 1.22- 4.04) ], WBC at diagnosis 〉 50×10^9/L [P= 0.024, HR = 2.11 (95%CI 1.11-4.02) ], donor age 〉 35 years [P = 0.031, HR = 1.96 (95% CI 1.06- 3.60) ] and without cGVHD [P = 0.008, HR = 0.38 (95% CI 0.18- 0.78) ]. According to the risk factors before transplantation (non remission status, WBC at diagnosis 〉 50×10^9/L, donor age 〉 35 years), we then defined three subgroups with striking different OS at 3 years: no adverse factor (75.0%); one adverse factor (46.9%); two or three adverse factors (15.4%) (x^2 = 26.873, P〈0.001). Conclusion Allo-HSCT is a promising and safe choice for patients with refractory and relapsed AML and relapse is the major cause of the tra
