确诊时高NPM1突变型等位基因负担可预测新发AML临床预后不良。

摘要:

携带突变型NPM1的急性髓系白血病(AML)是一种在2016年修订的WHO分类中新发现的独立实体类型,与预后良好相关。虽然既往研究都是以二元方式对NPM1进行评估,但目前对其突变等位基因对诊断的意义仍知之甚少,共突变(除了FLT3)的效应也未进行广泛评估。

Sanjay S. Patel等人对109位携带NPM1的新发AML患者的靶向测序数据进行回顾性分析,对NPM1基因突变等位基因频率(VAF)、共突变和患者预后的临床参数的潜在意义进行评估。

研究人员发现携带高NPM1 VAF(前1/4)的患者,与其他NPM1突变类型患者相比,总体存活期和无事件存活期均明显缩短(中位值 12.1 vs 未达到,p<0.0001;7.5 vs 65.44,p<0.0001)。无论采用单变量还是多变量分析,高NPM1 VAF均显著降低首次缓解即采用干细胞移植治疗和携带突变型DNMT3A的患者的预后(p=0,0004和p<0.0001)。

本研究结果提示NPM1突变对新发AML患者的预后效应或许受相关的突变等位基因负担影响。
