摘要 为探讨中下段直肠癌肿瘤组织E-cadherin,MMP-2和VEGF的表达及其与肿瘤侵袭转移的关系。笔者采用免疫组化技术检测56例中下段直肠癌肿瘤组织中E-cadherin,MMP-2和VEGF的表达。结果示,44.6%(25/56)的中下段直肠癌E-cadherin表达阴性;其中T3的阴性率为63.0%,明显高于T2和T1的26.1%和33.3%(P=0.028)。淋巴结转移阳性的直肠癌E-cadherin表达阴性率为62.1%,明显高于淋巴结转移阴性者的25.9%(P=0.007)。MMP-2表达阳性率为75.0%(42/56);其中T3,T2阳性率分别为88.9%,69.6%,明显高于T1期的33.3%(P=0.013)。浸润型直肠癌MMP-2表达率为91.2%,明显高于膨胀型的40.0%(P=0.001)。淋巴结转移阳性者MMP-2表达率为86.2%,明显高于淋巴结转移阴性的63.0%(P=0.045)。VEGF表达率为57.1%(32/56);其中T3VEGF表达率为74.1%,明显高于T2和T1期的43.5%和33.3%(P=0.043);淋巴结转移阳性者VEGF表达率为72.4%,明显高于淋巴结转移阴性的40.7%(P=0.017)。提示中下段直肠癌E-cadherin表达阴性和MMP-2,VEGF表达阳性与肿瘤侵袭和转移有密切关系。
