J Clin Oncol:RUNX1突变提示CN-AML不良预后

  一项来自美国的研究发现,在细胞遗传学正常的急性髓系白血病(CN-AML)患者中,RUNX1突变提示不良预后。研究7月2日在线发表于《临床肿瘤学杂志》(J Clin Oncol)。

  研究针对接受阿糖胞苷/蒽环类药物为基础的一线治疗的CN-AML患者(<60岁175例;≥60岁225例),使用直接测序法检查RUNX1突变状态,并分析其与预后的关系。结果发现,与RUNX1野生型CN-AML患者相比,RUNX1突变型患者完全缓解(CR)率较低(<60岁,P=0.005;≥60岁,P=0.006),无病生存时间较短(<60岁,P=0.058;≥60岁,P<0.001),总生存期较短(<60岁,P=0.003;≥60岁,P<0.001)。

  研究同时发现,RUNX1在≥60岁患者中较常见,且几乎从不与NPM1突变同时存在。RUNX1突变肿瘤的基因表达谱(微阵列法)与原始造血干细胞相似。
