乳腺癌中p130Cas和c-erbB-2的表达及其临床意义

目的研究p130Cas蛋白和c-erbB-2蛋白在乳腺癌组织中的表达，探讨它们与乳腺癌患者临床病理因素的关系，以评价乳腺癌的预后。方法采用免疫组化SP法检测53例原发乳腺癌，10例乳腺纤维腺瘤，10例正常乳腺组织中p130Cas和C-erbB-2蛋白的表达情况。结果与正常乳腺组织和乳腺纤维腺瘤相比较，乳腺癌组织中p130Cas和c-erbB-2的表达显著增高（P均〈0．01）。p130Cas的表达与患者的年龄，绝经状况，肿瘤细胞的ER，PR表达情况和组织学分级相关，而与肿瘤大小，淋巴结转移状况及病理学分期无关。c-erbB-2表达与患者的年龄、绝经状况、肿瘤大小、PR表达和病理学分期无关，而与ER表达、组织学分级和淋巴结转移有关。p130Cas和c-erbB-2的表达无相关性。结论p130Cas和c-erbB-2与乳腺癌细胞的恶性转化、分化程度有关，c-erbB-2还与乳腺癌的转移有关，检测p130Cas和c-erbB-2蛋白表达情况有助于对乳腺癌患者预后的评价。

The expression and clinical significance of p130Cas and c-erbB-2 in human breast cardnoma

Objective To explore the expression of p130Cas and c-erbB-2 in human breast carcinoma and the relationship between p130Cas and c-erbB-2 levels with clinical and pathological characteristics. Methods Immunohistochemistry SP staining was applied to detect the expression of p130Cas and c-erbB-2 in tumor tissues from 53 cases of human primary breast carcinoma,10 cases of breast fibroadenoma and in 10 cases of normal breast tissues. Results Breast carcinoma tissues showed higher levels of p130Cas and c-erbB-2 than normal and fibroadenoma tissues(both P＜0.01).The expression of p130Cas was related with age, menopausal status, ER, PR status and histological grades, but not related with tumor size, lymph node status and pathological stages. The expression of c-erbB-2 was related with ER status, histological grades and lymph node status, but not related with age, menopausal status, PR status, tumor size and pathological stages. There were no significant correlations between p130Cas and c-erbB-2. Conclusion p130Cas and c-erbB-2 have relations with the malignant transformation and differentiation of breast carcinoma.c-erbB-2 is associated with metastasis of breast carcinoma.p130Cas and c-erbB-2 can be served as useful indicators in the prognosis of breast carcinoma.
