摘要: 目的 探讨免疫组织化学(immunohistochemistry,IHC)和荧光原位杂交技术在乳腺癌人类表皮生长因子受体2(human epidermal growth factor receptor 2,HER2)检测中的问题。方法 对西安交通大学第一附属医院病理科309例HER2 IHC 2+乳腺癌病例进行荧光原位杂交(fluorescence in situ hybridization,FISH)检测,包含2018年院内送检的159例乳腺癌标本与2016~2019年外院送检的96例标本及2010年至2012年院内送检的54例HER2 IHC 2+的乳腺癌进行FISH检测。结果 院内2018年送检乳腺癌HER2 IHC 2+病例FISH检测结果阳性率明显低于外院送检和院内送检的2010年至2012年病例。结论 临床考虑需要进行HER2治疗的乳腺癌患者,对于下级医院送检的HER2阳性的病例都应进一步进行免疫组织化学检测或FISH检测,对于一些早期诊断为HER2阴性的病例均应进行复查,以精确指导治疗。

Abstract: Objective To explore the problems of immunohistochemistry and fluorescence in situ hybridization in HER2 detection of breast cancer. Methods A total of 309 HER2 IHC 2+ breast cancer samples underwent FISH analysis,including 159 specimens submitted at our hospital in 2018,54 specimens between 2010 and 2012,and 96 specimens from external hospitals between 2016 and 2019. Results The positive rate of FISH test results for breast cancer HER2 IHC 2+ cases in 2018 was significantly lower than that of specimens from other hospitals and the hospital from 2010 to 2012. Conclusion Patients with breast cancer expected to undergo HER2-targeted therapy,particularly those from subordinate hospitals or diagnosed at an early stage,should be further tested using immunohistochemical analysis or FISH to guide precision medicine.
