Abstract
目的研究混合谱系白血病(MLL)基因重排阳性急性髓系白血病(AML)患者行异基因造血干细胞移植(allo-HSCT)的预后特点。方法回顾性分析2009年9月至2016年5月于苏州大学附属第一医院行allo-HSCT的47例MLL基因重排阳性AML患者的临床资料。结果全部47例MLL重排阳性AML患者中男24例,女23例,中位年龄30(15~58)岁,M4/M5共36例(76.6%)。移植后2年总生存(OS)率为(64.4±8.4)%,无病生存(DFS)率为(47.3±9.3)%,复发率为41.0%,移植相关死亡率为17.9%。45例患者检出11q23易位,2例染色体核型正常患者检出MLL部分串联重复。t(6;11)组(16例)、t(9;11)组(15例)、其他类型组(16例)的2年OS率差异无统计学意义(χ2=1.509,P=0.472)。多因素分析显示,移植时年龄>45岁是影响OS的独立危险因素[HR=4.454(95%CI 1.314~15.099),P=0.016],移植前MRD阳性是影响患者DFS[HR=4.236(95%CI 1.238~14.495),P=0.021]、复发[HR=5.491(95% CI 1.371~21.995),P=0.016]的独立不良预后因素,移植前疾病处于非CR状态患者移植相关死亡风险增高[HR=10.370(95%CI 1.043~103.110),P=0.046]。结论移植时年龄>45岁、移植前疾病处于非CR状态、移植前MRD阳性为影响allo-HSCT治疗MLL基因重排阳性AML患者预后的危险因素。
