摘要 【目的】探讨MMP一9在非小细胞肺癌(NSCI。C)组织中的表达及其与NSCI,C临床侵袭、转移的关系。【方法】以51例NSCLC患者癌组织(A组),36例癌旁组织(B组)和18例肺良性病变组织为研究对象,标本经外科手术收集,用免疫组织化学方法观察肺癌组织、癌旁组织和肺良性病变组织中MMP-9的表达水平,分析其病理的意义。【结果】A组中MMP-9的表达明显高于B组和c组(均P〈O.05)。MMP9在鳞癌中表达高于腺癌(P〈0.05),并且阳性率随临床分期增高而升高(P〈o.01);有淋巴结转移者的肺癌组织其阳性率明显高于无淋巴结转移者(P〈O.01)。【结论]MMP-9在非小细胞肺癌组织中高表达,可能与肺癌的侵袭和转移有关。
