摘要 [目的]评价CyclinE和PTEN蛋白在大肠癌及癌旁组织中的表达及临床意义。[方法]选择60例大肠癌标本及40例距癌组织5cm处的肠黏膜组织,采用免疫组化EnVision二步法检测组织中CyclinE、PTEN蛋白的表达情况。[结果]CyclinE在大肠癌组织中阳性率高于癌旁组织(27.50%vs.63.35%,P=0.0000);CyclinE在大肠癌高、中、低分化中阳性率逐渐升高,淋巴结转移者CyclinE阳性表达率高于无淋巴转移者(P=0.036)。而PTEN则相反,在大肠癌中PTEN阳性表达率低于癌旁组织。[结论]CyclinE和PTEN蛋白表达与大肠癌的发生发展及生物学行为有关。
