摘要：

目的　探讨非小细胞肺癌 (NSCLC)组织中基质金属蛋白酶 2 (MMP 2 )和基质金属蛋白酶 9(MMP 9)的表达水平及其预后意义。方法　采用免疫组化SP法检测 2 8例正常肺组织、3 2例癌旁异型增生肺组织和 62例NSCLC组织中MMP 2和MMP 9的表达水平。结果　NSCLC组织中MMP 2 ( 77.4% )和MMP 9( 80 .6% )阳性表达率均显著高于癌旁异型增生组织和正常肺组织 (P均 <0 .0 0 5 )。腺癌和腺鳞癌中MMP 2和MMP 9阳性表达率均显著高于鳞癌 (P均 <0 .0 5 )。MMP 2和MMP 9的阳性表达率随TNM分期而增加 ,Ⅲ +Ⅳ期显著高于Ⅰ +Ⅱ期 (P <0 .0 2 5 ,P <0 .0 5 )。有淋巴结转移者MMP 2和MMP 9阳性表达率高于无淋巴结转移者 (P <0 .0 0 5 ,P <0 .0 5 )。生存 1、3年的患者MMP 2和MMP 9阳性表达率均高于 5年以上存活者 (P <0 .0 5 ,P <0 .0 0 5 )。结论　NSCLC组织内MMP 2和MMP 9阳性表达可能是预测肿瘤恶性行为的有用指标。
