摘要 目的检测结肠癌中过氧化物氧化还原蛋白(PRDX)1、2和3的表达,分析其临床意义。方法 95例结肠癌患者临床资料及术后标本作为观察组,75例结肠管状腺瘤标本作为对照组,75例距肿瘤边缘>5 cm的正常结肠黏膜组织作为正常对照组。应用免疫组化方法检测三组中PRDX1、2和3的表达。结果三组中PRDX1、2和3表达的阳性率差异均有统计学意义。观察组中PRDX1、2和3表达的阳性率与肿瘤的最大径、浸润深度、脉管内瘤栓和Ki67的表达密切相关。观察组中PRDX1、2和3之间的表达均未见明显相关性。结论结肠癌术后组织中PRDX1、2和3高表达是促进肿瘤的发生和进展的重要因素,三者间无明显的协同作用。
