人胃癌组织中Ezrin、ICAM-1的表达及意义的研究

目的 探讨Ezrin、ICAM-1在胃癌中的表达及其意义.方法 应用免疫组化S-P法检测Ezrin、ICAM-1在78例胃癌组织、30例胃良性病变组织、30例正常胃黏膜组织的表达,分析其与临床病理特征的关系及相关性.结果 ①胃癌组织中Ezrin、ICAM-1蛋白表达阳性率显著高于胃良性病变及正常胃黏膜组织(P<0.01),有淋巴结转移组明显高于无淋巴结转移组(P<0.05),13、T4组明显高于T1、T2组(P<0.05),Ⅲ、Ⅳ期组明显高于Ⅰ、Ⅱ期组(P<0.05).②胃癌组织中Ezrin蛋白表达水平与粘附分子ICAM-1蛋白表达水平之间呈正相关(r=0.46,P=0.00).③联合检测Ezrin、粘附分子ICAM-1在胃癌组织中的表达可明显提高检测胃癌转移的敏感性和特异性(P<0.05).结论 Ezrin、粘附分子ICAM-1的过度表达与胃癌的发生发展及侵袭转移有关,联合检测两种指标能明显提高检测胃癌转移的敏感性和特异性.

Expression and significance of Ezrin and ICAM-1 in gastric carcinoma

Objective To investigate the expression and significance of Ezrin and ICAM-1 in gastric carci- noma.Methods The expression of Ezrin and ICAM-1 were examined by S-P immunohistochemistry assays in 78 ca- ses of gastric carcinoma.30 cases of nonmalignant tissue and 30 cases of normal stomach.The relationship between them and their pathological characteristics were analyzed.Results ①The expression rates of Ezrin and ICAM-1 were obviously higher in carcinoma group than that of nonmalignant group and normal group(P<0.01),in the lym- phatic metastasis group than that in non lymphatic metastasis group(P<0.05),and in T3.T4 group and than that in T1,T2 group(P<0.05).②The expression level of ICAM-1 was positively related with that of Ezrin(r=0.46. P=0.00).③The test of the expression of Ezrin and ICAM-1 simutaniously could obviously increase the sensitivity and specificy for detecting the metastasis of stomach malignant tumor(P<0.05).Condusion The over expression of Ezrin and ICAM-1 is related to the pathogenesis and invasion as well as metastasis of stomach carcinoma.The combined detection of two markers can obviously increase the sensitivity and specificy for predicting metastasis of stomach carcinoma.
