摘要 目的:探讨免疫组织化学技术(IHC)与荧光原位杂交技术(FISH)检测乳腺癌HER2表达的差异性。方法:回顾性分析2014年6月至2019年10月本院收治的387例乳腺癌患者的临床资料,分别行IHC与FISH检测HER2表达,分为IHC组和FISH检测组,对比两组的阳性率及一致性。结果:387例乳腺癌患者中,IHC检测HER2表达(0)74例、(1+)113例、(2+)128例、(3+)72例,阳性率为51.68%(200/387),阴性率为48.32%(187/387);FISH检测,HER2基因扩增(+)166例(42.89%),HER2基因非扩增221例(57.10%);200例HER2表达阳性的患者,HER2基因扩增161例,符合率为80.50%;187例HER2表达阴性的患者,HER2基因非扩增182例,符合率为97.33%;组间比较,差异无统计学意义(P>0.05)。结论:IHC与FISH检测乳腺癌HER2表达的一致性较高,临床可结合两者检查结果指导乳腺癌治疗及评估预后。
