原癌基因的激活和抑癌基因的失活是肿瘤形成的重要分子机制。原癌基因HER-2是人类表皮生长因子受体(EG—FR)家族的第二个成员,该家族中的受体均位于细胞膜上,在许多组织中都能发现。它在胎盘、胚胎上皮组织及许多肿瘤细胞中呈高表达,而在正常组织中为阴性或微量表达。HER-2作为肿瘤发生的癌基因, 相似文献

BACKGROUND: Fluorescence in situ hybridization is advocated for precise assessment of HER-2/neu status in breast carcinoma; however, few objective data compare available kits for clinical laboratories contemplating development of the test. METHODS AND RESULTS: Thirty breast carcinomas were analyzed for HER-2/neu amplification with the PathVysion kit (Vysis, Downers Grove, IL) and INFORM kit (Ventana Medical Systems, Tucson, AZ). Each kit was evaluated for morphology, background staining, technical and interpretation time, and cost. PathVysion detected amplification in seven of 30 cases (23.3%); INFORM detected six of 30 cases (20%). A greater percentage of PathVysion cases showed good morphology and lower background staining than INFORM. Technical and interpretation times, as well as cost, were less with PathVysion than INFORM. CONCLUSION: PathVysion is superior to INFORM because it produces better morphology and less background staining and is faster and less expensive than the INFORM kit. It also includes a chromosome 17 probe that serves as an internal control and enables correction for chromosome 17 aneuploidy. 相似文献

BACKGROUND: HER-2 status is generally determined by immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH). Both methods are only semiquantitative, require a tumor sample, and can be difficult to reproduce. We compared these methods with 2 quantitative approaches, one measuring HER-2 gene copy number in tissue by real-time quantitative PCR (qPCR), and the other measuring shed HER-2 protein in serum by ELISA in patients with metastatic disease. METHODS: We analyzed 52 cases of metastatic breast cancer for which both serum collected at the diagnosis of metastasis and stored primary breast tumor specimens were available. The within- and between-run imprecision of real-time qPCR and ELISA were evaluated according to Clinical and Laboratory Standards Institute (formerly known as NCCLS) recommendations. Concordance among the 4 methods was assessed by calculating the kappa statistic and its 95% confidence interval (95% CI). RESULTS: The CVs for within- and between-run imprecision were both <10% with qPCR and ELISA. There was good agreement of results between qPCR and IHC (kappa = 0.81; 95% CI, 0.64-0.99), qPCR and FISH (kappa = 0.77; 95% CI, 0.58-0.96), ELISA and IHC (kappa = 0.65; 95% CI, 0.41-0.89); and ELISA and FISH (kappa = 0.69; 95% CI, 0.46-0.92). CONCLUSIONS: Measurements of HER-2 gene expression by qPCR and of serum HER-2 protein by ELISA are highly reproducible approaches for determining HER-2 status in metastatic breast cancer. In addition, ELISA eliminates the need for biopsy. 相似文献

目的 比较荧光原位杂交(FISH)和免疫组化(IHC)检测乳腺癌组织中人表皮生长因子受体2(HER-2)基因扩增及蛋白表达的一致性,并探讨HER-2基因扩增与临床病理特征的关系.方法 回顾性分析本院采用FISH法检测HER-2基因状态的112例乳腺癌,与IHC结果进行一致性分析,并对HER-2基因扩增与年龄、组织学分级、淋巴结转移及激素受体的关系进行统计学分析.结果 112例浸润性乳腺癌中,HER-2基因扩增57例,其中IHC检测HER-2(3+)者27例,(2+)者29例,(1+)者1例,分别占IHC病例总数的96.4% (27/28)、48.3% (29/60)和5.3% (1/19).HER-2基因扩增与雌/孕激素受体呈负相关,而与年龄、组织学分级、淋巴结转移差异不显著.结论 对于IHC检测HER-2(3+)、(+或0)的病例可选择性做FISH进行确认,对于HER-2(2+)病例应常规进行FISH检测,以便更加准确和客观地对治疗和预后进行评价. 相似文献

The detection of the biological parameters of the tumor before the treatment beginning becomes of more importance. The present study aimed to carry out the comparative analysis of the molecular markers expression (P53, Ki-67, Her-2/neu, Bcl-2, Bax, ER, FasL and CD95) at the cytologic and the correspondent histologic samples. The 18 tissue samples of the breast cancer were investigated. The immunocytochemical and the immunohistochemical methods of the molecular markers determination were used. Our study showed the correlation between two methods and the possibility of the use of the immunocytochemical staining as routine method of the molecular markers expression determination. 相似文献
