摘要 为探讨细胞间粘附分子- 1(ICAM- 1) 在原发性肝细胞癌的表达状况及其在肝癌发生中的作用,利用免疫组织化学技术链菌素亲生物蛋白(LSAB) 法检测30 例乙型肝炎后肝细胞癌及癌旁肝组织ICAM- 1 的表达情况。结果 肝癌组织中,ICAM- 1 存在一定程度的表达,其中癌组织阳性率为43 .3% ,多为弱表达;癌旁肝组织明显高于癌组织,阳性率为78 .6 % ,多呈弥漫强阳性表达,二者差异有显著性( P< 0 .01) 。结论 ICAM- 1 与肝癌的发生有一定的关系,ICAM- 1缺乏或弱表达可能是原发性肝细胞癌发生过程中的重要免疫逃逸机制之一。 To study the expession and function of intercellular adhesion molecule-1(ICAM-1) in hepatocellular carcinoma(HCC),30 cases of primary HCC were detected by immunohistochemistry method Result the rate of ICAM-1 expression in the carcinoma tissues was 43.3%,showing mostly local,weak stain,while in pericarcinoma tissues,it was 78.6%,appearing diffused,stronger stain.The difference of ICAM-1 expression between them showed significance(P<0.01).No expression or weak expression of ICAM-1 might be an important immune escape mechanism in the development of HCC.
