摘要 目的探讨结直肠癌中基质金属蛋白酶-9(MMP-9)、表皮生长因子受体(EGFR)的表达及其与临床病理特征的关系。方法选择132例结直肠癌组织标本及其癌旁正常组织,采用免疫组化法检测组织中MMP-9、EGFR的表达,并结合临床病理特征进行分析。结果 MMP-9、EGFR在结直肠癌组织中的阳性表达率为77.3%、67.4%,明显高于癌旁正常组织(P<0.01);MMP-9及EGFR的阳性表达均与肿瘤浸润深度、Dukes分期和淋巴结转移相关(P<0.05),而与患者年龄、性别及肿瘤部位等无明显相关(P>0.05);MMP-9与EGFR在结直肠癌组织中表达呈正相关(rs=0.758,P<0.01)。结论 MMP-9和EGFR在结直肠癌中均有高表达,与结直肠癌的发生、浸润、淋巴结转移密切相关,可为结直肠癌患者预后判断提供客观依据。
