摘要 目的探讨结肠癌中DNA结合抑制蛋白-1(Id-1)的表达与肿瘤细胞分化程度、浸润深度、淋巴结转移及TNM分期的关系。方法用原位杂交的方法分别检测17例结肠腺瘤、16例不典型增生、48例结肠癌及15例癌旁正常组织中Id-1的表达。结果正常肠黏膜组织中Id-1蛋白偶有表达,在结肠腺瘤、不典型增生、结肠癌组织中的阳性表达率分别为35.3%、43.75%、77.08%,三者比较差别有统计学意义(P<0.05)。Id-1表达与分化程度无关(P>0.05),与浸润深度、淋巴结转移、TNM分期有关,差异有统计学意义(P<0.05)。结论 Id-1蛋白在结肠癌组织中表达明显升高,并与结肠癌侵袭转移及TNM临床分期相关,可作为结肠癌预后判断的指标之一。
