摘要 目的:初步观察急性早幼粒细胞白血病(acute promyelocytic leukemia,APL)患者PML/RARα融合基因在治疗过程中的动态变化。方法:收集2008年1月至2012年6月广东省人民医院初诊APL患者临床资料及融合基因表达监测结果。结果:47例初诊APL患者,男30例,女17例,中位年龄29(6~67)岁。PML/RARα融合基因以ABL基因作为内参进行标化(normalized quantity,NQ)。治疗前31例患者NQ中位数0.446 7(0.044~1.451 2)。患者获得完全血液学缓解(CR)时及CR后巩固化疗1~4疗程NQ中位数分别为0.000 53(0~0.030 4)、0(0~0.001 037)、0(0~0.000 27)、0(0~0.000 24)、0(0~0.000 08),基因表达阳性率分别为82.6%、31.6%、26.1%、9.1%、4.8%,维持治疗期间降至0。结论:PML/RARα融合基因表达水平能够直观、有效的反应APL患者治疗过程中微小残留病变(minimal residual disease,MRD)水平的变化,可用于APL患者的疗效评估。
