摘要
目的探讨免疫组化(immunohistochemistry,IHC)与荧光原位杂交(fluorescence in situ hybridization,FISH)两种技术在检测乳腺浸润性导管癌HER-2/neu为2+时的一致性。方法收集乳腺浸润性导管癌并经IHC证实为2+的标本66例,同时进行FISH检测,比较两者结果的相关性。结果 FISH检测发现在66例IHC为2+的病例中,HER-2/neu基因的阳性率为28.8%(19/66);ER-PR-乳腺癌HER-2/neu基因的阳性率(47.4%)明显高于ER+PR+乳腺癌HER-2/neu基因的阳性率(17.5%),两者具有显著性差异(P<0.05)。结论 IHC证实HER-2/neu为2+时必须进行FISH检测。
Objective To investigate the concordance between immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) when applied for testing the HER -2/neu status in breast infiltrating ducta] carcinomas scored IHC (2 + ). Methods Totally 66 cases of breast infiltrating ductal carcinoma scored IHC (2 + ) were collected. For all the cases, the amplification of HER -2/neu was al- so detected by FISH. The results from the two methods were analyzed. Results Of the 66 cases, the positive rate of HER - 2/neu gene amplification was 28.8% (19/66). The positive rate of HER -2/neu gene amplification in ER -PR - cases (47.4%) was significantly higher than that in ER + PR + cases( 17.5% ) ( P 〈 0.05 ). Conclusion It is definitely necessary to do the FISH test of HER - 2/neu in breast carcinomas which are scored 2 + by IHC.
