摘要 目的检测肝细胞癌中真核生物翻译起始因子(EIF)-5A2、突变型P53基因(P53)和上皮型黏附素(E-cadherin)的表达,关注三者在不同临床特征中的差别及相关性。方法 90例肝细胞癌临床资料及术后蜡块组织作为观察组,以57例距肿物边缘>5 cm的非肿瘤性肝组织作为对照组,采用免疫组织化学技术检测两组EIF-5A2、P53和E-cadherin的表达。结果两组EIF-5A2、P53和E-cadherin的表达差异显著。观察组EIF-5A2、P53和E-cadherin的表达在不同肿瘤结节数量、直径、分化程度、转移、脉管浸润中的差异显著。相关性分析显示观察组中EIF-5A2和P53的表达具有正相关性、EIF-5A2和E-cadherin的表达具有负相关性。结论肝细胞癌组织中EIF-5A2和P53高表达、E-cadherin低表达对肿瘤进展有促进作用,EIF-5A2在作用过程中不仅对P53基因突变有一定作用,还对以E-cadherin为主的黏附蛋白有一定调节。
