目的　检测Claudin-1蛋白在非小细胞肺癌（NSCLC）原发癌组织及其淋巴结转移癌组织中的表达，并探讨其与NSCLC各临床病理特征和预后的关系。方法　利用组织芯片技术，采用免疫组织化学染色方法检测Claudin-1在1998年1月－2003年12月收集的279例NSCLC原发癌组织及其55例淋巴结转移癌组织、54例癌旁正常肺组织中的表达。运用SPSS 13.00统计软件对相关数据进行统计分析。结果　Claudin-1在279例NSCLC原发癌组织和55例淋巴结转移癌组织中的阳性表达率分别为69.9%和50.9%，在鳞癌和腺癌中的阳性表达率分别为83.7%和55.7%，在高、中分化癌组和低分化癌组中的阳性表达率分别为78.6%和62.7%。Claudin-1在原发癌组织中的阳性表达率高于其淋巴结转移癌组织（P＜0.05）；在鳞癌中的阳性表达率高于腺癌（P＜0.05），且在高、中分化癌组中的阳性表达率高于低分化癌（P＜0.05）。Claudin-1阳性表达之NSCLC患者的生存率高于阴性表达者（P＜0.05）。结论　Claudin-1在NSCLC中的表达与患者的组织学类型及病理分级有关，且Claudin-1是NSCLC侵袭、转移的抑制因子，并且可能是一个有用的预后因子。
