摘要 目的 探讨表达e1a2转录型的慢性粒细胞白血病(CML)患者的临床及实验室特征.方法 采用实时定量聚合酶链反应(RT-PCR)、荧光原位杂交(FISH)和二代测序等技术对上海交通大学附属第一人民医院收治的1例表达e1a2转录型CML患者的bcr-abl融合基因进行定量、定性及突变检测,并结合文献分析P190 CML的临床及实验室特征.结果 bcr-abl定性:e13a2/e14a2阴性,e19/a2阴性,e1a2阳性;bcr-abl定量:40 %(bcr-abl/abl);182/200细胞显示2融合1红1绿的典型e1a2融合信号;abl激酶区未发现突变.结论 e1a2转录型更易伴随e13a2/e14a2出现,表达e1a2的CML临床表现和实验室结果具有一定异质性,单独表达e1a2的CML患者接受酪氨酸激酶抑制剂治疗效果不佳.
