摘要
目的 探讨 N-钙黏附素(N-cadherin)、基质金属蛋白酶-9(MMP-9)在直肠癌中表达的临床意义。方法 采用免疫组织化学两步法对 80 例直肠癌组织中的 N-cadherin、MMP-9 表达进行检测。结果 (1)N-cadherin在直肠癌组织中的阳性表达率为41.25%,其中 A、B期患者和 C、D期患者分别为28.9%和57.1%(P<0.05);淋巴结转移组和无淋巴结转移组分别为58.6%和31.4%(P<0.05);肝转移组和无肝转移组阳性表达率分别为69.2%,35.8%( P<0.05) 。(2) MMP-9在直肠癌组织中的阳性表达率为60%,其中A、B期患者和C、D期患者阳性表达率分别为40%,85.7%(P<0.01);淋巴结转移组和无淋巴结转移组阳性表达分别为82.8%,47.1%(P<0.01),发生肝转移组和无肝转移组阳性表达率分别为84.6%,55.2%(P<0.05)。( 3)Kaplan Meier分析,N-cadherin、MMP-9 阳性表达者的生存时间和5年生存率明显低于N cadherin、MMP-9阴性表达者(P<0.01)。结论 N-cadherin、MMP-9 的表达与直肠癌关系密切,对判断其预后可能具有重要意义。
