2、及其临床意义。采用PCR和直接测序法检测31例AMLl·ETO阳性AML患者c一胁基因17外显子突变的发生情况,并分析c.胁基因突变与患者的临床、实验室特征以及疗效的关系。结果表明:31例患者中14例检测到C-舡f突变,突变率为45.16%,突变组男性患者的比例为71.43%、初诊时白细胞计数>10×10’/L患者的比例为78.57%和伴有髓外浸润患者的比例为21.43%,均明显高于无突变组(29.41%、41.18%、O%,P=0.020,0.036,0.045),两组患者的年龄和骨髓原始细胞比例无明显差异(P=0.437和0.510)。
3、c一舡f突变和无突变组化疗完全缓解(CR)率(64.29%:80%)和复发率(58.33%:21.43%)的差异无统计学意义(P=0.344和0.054),而死亡率(57.14%)在c一舡f突变组明显高于无突变组(20%,P=0.039)。结论:AMLl-ETO阳性AML患者c一胁突变常见,突变患者预后差,常规检测c一胁突变对患者的危险度分层、预后评估和选择有效治疗方案有重要意义。关键词急性髓系白血病;AMLl一ETO融合基因;c-胁突变中图分类号R733.71文献标识码Adoi:10.7534/j.issn.1009-2137.2013.
