摘要: 目的 研究整合素连接激酶(ILK)、E-钙黏蛋白(E-cadherin)在宫颈上皮内瘤变(CIN)及宫颈鳞癌组织中的表达情况,分析其与临床病理资料的关系。方法 采用免疫组化方法检测ILK及E-cadherin在54例CIN、38例宫颈鳞癌及20例正常宫颈组织中的表达。结果 ILK在正常宫颈、CINⅠ、CINⅡ~Ⅲ及宫颈鳞癌中的阳性表达率分别为25.0%、68.8%、78.9%、97.3%。ILK在CIN及宫颈鳞癌中的阳性表达率显著高于正常宫颈(P<0.05)。E-cadherin在正常宫颈、CINⅠ、CINⅡ~Ⅲ及宫颈鳞癌中的阳性表达率分别为100.0%、75.0%、55.3%、36.8%。E-cadherin在CIN及宫颈鳞癌中的阳性表达率显著低于正常宫颈(P<0.05)。在宫颈鳞癌组织中ILK的表达与E-cadherin呈负相关(r=-0.531,P<0.01)。E-cadherin阳性表达还与宫颈鳞癌临床分期、分化程度、淋巴结转移有关(P<0.05)。结论 ILK、E-cadherin可作为区分正常宫颈组织与CIN及宫颈鳞癌的标记物,E-钙黏蛋白还与宫颈癌恶性生物学行为有关。

Abstract: Objective To study the expression of integrin-linked kinase(ILK) and E-cadherin in cervical intraepithelial neoplasia(CIN)and cervical squamous cell carcinoma,and analyze their relation with clinical pathological data.Methods Immunohistochemistry was used to detect the expression of ILK and E-cadherin in 54 cases of CIN,38 cases of cervical squamous cell carcinoma and 20 cases of normal cervical tissue.Results The positive expression rate of ILK in normal cervical,CINⅠ,CINⅡ~Ⅲ and cervical squamous cell carcinoma was 25.0%,68.8%,78.9% and 97.3%,respectively.The positive rate of ILK in CIN and cervical squamous cell carcinoma was significantly higher than that in normal cervix(P<0.05).The positive expression rate of E-cadherin in the normal cervix,CINⅠ,CINⅡ~Ⅲ and cervical squamous cell carcinoma was 100.0%,75.0%,55.3% and 36.8%,respectively.The positive rate of E-cadherin in CIN and cervical squamous cell carcinoma was significantly lower than that in normal cervix(P<0.05).There was a significant negative correlation of the expression of ILK and E-cadherin in cervical squamous cell carcinoma(r=-0.531,P<0.01).The positive expression of E-cadherin had correlation with clinical stage,differentiation and lymph node metastasis in cervical squamous cell carcinoma(P<0.05).Conclusion ILK and E-cadherin could be used as a marker to distinguish normal cervix from CIN and cervical squamous cell carcinoma.In addition,E-cadherin is also correlated with the malignant biological behavior of cervical cancer.
