摘要 目的探讨结直肠腺癌中Cox-2、MMP-9、E-cadherin的表达及与浸润、转移的关系。方法应用免疫组化SP法检测结直肠腺癌、正常结直肠黏膜组织中Cox-2、MMP-9、E-cadherin蛋白的表达。结果结直肠腺癌组织中,Cox-2、MMP-9的阳性率(61.25%、66.25%)和E-cadherin的异常表达率(68.75%),显著高于正常结直肠黏膜组织(P<0.01)。三者均与淋巴结转移有关(P<0.05),其中E-cadherin表达与组织分化程度有关(P<0.01)。Cox-2与MMP-9表达呈正相关(rs=0.409,P<0.01),与E-cadherin表达呈负相关(rs=-0.370,P<0.01)。结论结直肠腺癌中Cox-2、MMP-9、E-cadherin的异常表达与肿瘤转移有关,分析三者表达对结直肠腺癌的预后评估有重要指导意义。
