Abstract： 目的:探讨胰腺癌患者组织中MMP-9、TIMP-1的表达及其相互关系,分析其与临床及转移预后的关系.方法:免疫组织化学SP法检测63例胰腺癌、11例慢性胰腺炎和6例正常胰腺组织中MMP-9、TIMP-1的表达.结果:胰腺癌组织中MMP-9表达明显高于慢性胰腺炎和正常胰腺组织(58.7% vs 18.1%,0.0%;均P<0.05).TIMP-1在胰腺癌的表达低于正常胰腺组织(46.0% vs 100.0%,P<0.05).MMP-9和TIMP-1在胰腺癌组织中的表达与性别、年龄、组织学分级无关,而与患者的淋巴结转移、远处转移情况有关(P<0.05).结论:MMP-9、TIMP-1在胰腺癌组织中的表达变化可能与胰腺癌转移相关.
