摘要 目的探讨人表皮生长因子受体-2(HER-2)及拓扑异构酶Ⅱ(TOPOⅡ)在结直肠癌中的表达及相互关系,并探讨其意义。方法选取经手术切除的60例结直肠癌标本中切取的癌组织和距癌灶10~15cm的其癌旁正常肠组织,进行病理切片。免疫组化法检测60例结直肠癌及其癌旁正常组织HER-2和TOPOⅡ的表达水平,结合临床病理因素,运用SPSS16.0统计软件包进行统计分析。结果 HER-2在结直肠癌及癌旁正常组织阳性表达率分别为46.67%和10.00%,差异有显著性,HER-2在结直肠癌表达水平与分化程度、淋巴结累及情况、病理分期有关;TOPOⅡ在结直肠癌与癌旁正常组织表达率分别为55.00%和11.67%,差异有显著性,结合临床病理因素,TOPOⅡ表达水平仅与淋巴结有无转移、病理分期存在相关性;TOPOⅡ与HER-2蛋白表达水平在结直肠癌中存在正相关。结论 HER-2与TOPOⅡ两者在结直肠癌正相关表达,表明两者在结直肠癌的发生、侵袭和转移起着协同作用。
