    • 摘要: 目的:比较荧光原位杂交检测(FISH)、免疫组化技术(IHC)在乳腺癌HER-2基因及蛋白检测中的差异性与相关性.方法:以98例乳腺癌患者的手术病理切片为检测对象,分别进行FISH、IHC检测,分析两种检测结果.结果:IHC检测结果显示,阳性占53例(54.08%),阴性占45例(45.92%).FISH检测结果显示,阳性占比29例(29.59%),阴性占69例(70.41%).以FISH为金标准,IHC检测为-的符合率为42(93.33%),+的符合率5(17.86%),++的符合率11(78.57%),+++的符合率10(90.91%).结论:IHC初步筛查C-erbB-2蛋白,-、+++符合率较高,在++、+筛查中IHC符合率较低,建议在IHC筛查基础上再做FISH筛查,以明确HER-2基因状态.

    • 摘要: Objective To compare the consistence of fluorescence in situ hybridization (FISH) with immunohistochemistry (IHC) in detecting human epidermalgrowth factor receptor-2 (HER-2) status in infiltrating ductal breast carcinoma.Methods The expression of C-erbB-2 protein and HER-2 gene amplification of 346 cases with infiltrating ductal breast carcinoma was tested by IHC and FISH methods,and the results were compared.Results Among 346 specimens of infiltrating ductal breast carcinoma,HER-2 gene amplification was present in 145 cases (41.9%) by FISH,and absent in 201 cases (58.1%).IHC detection of C-erbB-2 protein results showed that (-) in 7 cases,(+) in 30 cases,(++) in 227 cases and (+++) in 82 cases.According to the guidline for the detection of HER-2 in breast cancer,(-) and (+) were negative results,(+++) was positive results,and (++) was uncertain.The positive rate of C-erbB-2 protein in 346 specimens was 23.7% (82/346).There were 7 cases with negative expression of C-erbB-2 by IHC,among which HER-2 gene amplification was absent in 7 cases with the coincidence rate of 100.0%.Five among 30 showed a negative result of (+) by IHC,but was positive in FISH,and the coincidence rate was 83.3%.In the 227 cases with a positive result of (++) by IHC,the amplification of HER-2 gene was present in 65 cases,with the coincidence rate of 28.6%.The positive result of (+ ++) was demonstrate in 82 cases,among whom the HER-2 gene amplification was detected in 75 cases,with the coincidence rate of 91.5%.The consistency of these two methods was very good in the cases with negative (-/+) or positive (+++) expression of C-erbB-2.The total concordance rate of HER-2 between IHC and FISH trials was 89.9% with the Kappa value of 0.768(P<0.001).HER-2 gene amplification was not related to age,tumor size,histological grade and lymph node metastasis (P>0.05).Conclusion HER-2 expression of infiltrating ductal breast carcinoma detected by IHC was highly consistent with FISH detection.IHC is a preliminary method to detect HER-2 status in infiltrating ductal breast carcinoma.However,in the cases with positive (++) expression of C-erbB-2,FISH should be performed to detect the gene amplification of HER-2.%目的 比较荧光原位杂交(FISH)和免疫组织化学(IHC)两种方法检测乳腺浸润性导管癌人类表皮生长因子受体2(HER-2)基因扩增及与C-erbB-2蛋白表达结果的一致性.方法 分别采用FISH和IHC法检测346例乳腺浸润性导管癌组织HER-2基因扩增和C-erbB-2蛋白表达,并对两种方法的结果进行统计学分析.结果 346例乳腺浸润性导管癌中,FISH检测HER-2基因扩增145例(41.9%),无扩增201例(58.1%).IHC检测显示,C-erbB-2蛋白(-)7例,(+)30例,(++)227例,(+++)82例.按乳腺癌HER-2检测指南,(-)和(+)为阴性结果,(+++)为阳性结果,(++)为不确定病例.全组IHC检测C-erbB-2蛋白阳性表达率为23.7% (82/346).IHC检测C-erbB-2蛋白(-)的7例患者经FISH检测无HER-2基因扩增,一致率为100.0%.IHC检测C-erbB-2蛋白(+)的30例经FISH检测25例无基因扩增,一致率为83.3%;227例(++)中有65例基因扩增,一致率为28.6%;82例(+++)中有基因扩增75例,一致率为91.5%.IHC和FISH检测HER-2状态的一致率为89.9%,具有高度一致性(Kappa值=0.768,P<0.001).HER-2基因扩增与年龄、肿瘤大小、组织学分级及淋巴结转移均无关(P>0.05).结论 IHC和FISH法检测乳腺浸润性导管癌HER-2表达状态有高度一致性.IHC可以作为初步筛查乳腺浸润性导管癌HER-2基因状态的首选检测方法,对于IHC检测结果为(++)的标本建议采用FISH法进一步明确HER-2基因扩增状态.
