摘 要:目的 比较Ph染色体阳性(Ph+)急性淋巴细胞白血病(ALL)患者应用化疗联合酪氨酸激酶抑制剂(TKI)后行异基因造血干细胞移植(allo-HSCT)和Ph染色体阴性(Ph-)ALL患者化疗后进行allo-HSCT的疗效和安全性.方法 2003年1月至2014年8月行allo-HSCT的55例B-ALL患者中配对选取19例Ph-ALL患者(Ph-ALL组)与19例TKI联合allo-HSCT的Ph+ALL患者进行回顾性分析.结果 Ph+ALL组和Ph-ALL组在性别、中位年龄、发病时外周血WBC> 30× 109/L的例数、合并中枢神经系统白血病的例数、移植前疾病缓解状态、移植时间、干细胞来源、供受者HLA相合情况、预处理方案、输入单个核细胞数和CD34+细胞数等方面基本匹配.Ph+ALL组和Ph-ALL组白细胞和血小板植活时间相当(12d和13d,P=0.284;14 d和17d,P=0.246).Ph+ALL组和Ph-ALL组3年总生存率和无病生存率分别为(67.5±12.4)%和(74.3±11.4)%(P=0.434)、(67.8±12.4)%和(74.3±11.4)%(P=0.456),差异均无统计学意义.Ph+ALL组和Ph-ALL组Ⅱ~Ⅳ度急性移植物抗宿主病(aGVHD)的累积发生率分别为(15.8±8.4)%和(21.1±9.4)%(P=0.665),其中Ⅲ~Ⅳ度aGVHD的累积发生率分别为(5.6±5.4)%和(11.5±7.6)%(P=0.541).慢性移植物抗宿主病(cGVHD)的累积发生率分别为(44.1±14.0)%和(44.1±13.0)%(P=0.835),其中广泛型cGVHD的累积发生率分别为(13.1±8.7)%和(6.2±6.1)%(P=0.379).Ph+ALL组和Ph ALL组累积复发率和累积非复发死亡率差异亦无统计学意义[分别为(10.8±7.2)%对(20.0±10.7)%(P=0.957)和(23.9±12.4)%对(7.1±6.9)%(P=0.224)].结论 Ph+ALL患者化疗联合TKI后行allo-HSCT与Ph-ALL患者行allo-HSCT的疗效相当.Objective To compare the efficacy of the Ph+ acute lymphoblastic leukemia (ALL) patients treated with combination of tyrosine kinase inhibitors (TKI) and chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) and Ph-ALL patients with allo-HSCT.Methods A total of 19 Ph+ALL patients were matched with 19 Ph-ALL patients from 55 B-ALL patients receiving allo-HSCT in our hospital between January 2003 and August 2014 and were analyzed retrospectively.Results Gender,median age,number of patients with blood white count more than 30 × 109/L,number of patients with meningeal leukemia,disease status before allo-HSCT,period of allo-HSCT,the source of stem cell from donors,HLA disparities between donor and recipient,conditioning regimens and number of infused mononuclear cells and CD34+ cells were comparable between two groups of Ph+ and 19 Ph-ALL patients.The median time of engraftment of neutrophil cells was 12 days versus 13 days (P=0.284) and that of platelet 14 days versus 17 days (P=0.246),which were comparable between two groups.The estimated 3-year overall survival (OS) in Ph+ and Ph-ALL groups was (67.5±12.4)% versus (74.3±11.4)% (P=0.434) and 3-year disease free survival (DFS) was (67.8±12.4)% versus (74.3±11.4)% (P=0.456),respectively.The cumulative incidence of degree 1-Ⅳ acute graft-versus-host disease (aGVHD) in Ph+ and Ph-ALL group was (15.8±8.4)% versus (21.1±9.4)% (P=0.665) and that of degree Ⅲ-Ⅳ aGVHD was (5.6 ± 5.4) % versus (11.5 ± 7.6) % (P=0.541),respectively.The cumulative incidence of cGVHD was (44.1J±14.0) % in Ph+ALL group versus (44.1 ± 13.0) % in Ph-ALL group (P=0.835) and that of extensive cGVHD was (13.1 ±8.7)% versus (6.2J±6.1)% (P=0.379),respectively.The cumulative relapse rate and the cumulative non-relapse rate in both group also have no statistical difference [(10.8±7.2)% versus (20.0±10.7)% (P=0.957) and (23
