Abstract

目的探讨异基因造血干细胞移植(allo-HSCT)前巩固化疗对第1次形态学完全缓解且微小残留病阴性(CR1/MRD−)中/高危急性髓系白血病(AML)患者预后的影响。方法对2010年1月至2019年3月在CR1/MRD−状态下接受allo-HSCT的155例中/高危AML(不含急性早幼粒细胞白血病)患者进行回顾性分析。结果全部155例患者中,102例获得CR1/MRD−后接受移植前巩固化疗(巩固组),53例获得CR1/MRD−后直接行allo-HSCT(非巩固组),两组中位年龄分别为39(18~56)岁、38(19~67)岁。巩固组、非巩固组移植后5年总生存率分别为(59.3±7.5)%、(62.2±6.9)%(P=0.919),无复发生存率分别为(53.0±8.9)%、(61.6±7.0)%(P=0.936),累积复发率分别为(21.9±5.4)%、(18.3±6.0)%(P=0.942),非复发死亡率分别为(22.4±4.3)%、(28.4±6.5)%(P=0.464)。多因素分析显示,移植前是否接受巩固化疗及其疗程(<2个/≥2个)对预后无显著影响。结论中/高危AML患者可在获得CR1/MRD−后直接进行allo-HSCT。
