摘　　要：目的探讨乳腺浸润性导管癌组织中间隙连接蛋白43(Cx43)及上皮性钙黏蛋白(E-cad)表达中的相关性。方法采用Elivision免疫组织化学法对89例乳腺侵润性导管癌组织及48例分区组织的Cx43与E-cad检测。结果乳腺浸润性导管癌的肿瘤区、交界区和远癌区的Cx43和E-cad蛋白表达具有较好的一致性(γ=0.460,P<0.01);在肿瘤区两者同时为阴性表达时,淋巴结转移率最高。结论 Cx43和E-cad在乳腺浸润性导管癌发生和发展过程中具有一定的协同作用,与其发生浸润转移有关。Objective To explore the correlation of Connexion43（Cx43）,E-cadherin（E-cad）in breast infiltrating ductal carcinoma tis-sue. Methods The expressions of Cx43 and E-cad proteins were detected in 89 cases breast infiltrating ductal carcinoma tissue,48 cases partition groups. by immunohistochemistry Elivision method. Results The expressions of Cx43 and E-cad has a better consistency in the tumor area,the border area and far cancer area of breast infiltrating ductal carcinoma. For both the negative expression in tumor area same time,the rate of lymph node metastasis was highest. Conclusion Cx43 and E-cad in breast invasive ductal carcinoma has a certain synergy in the process of the occurrence and development,which related to its metastasis occurred.
