摘要 目的检测胰岛素样生长因子-1(IGF-1)和胰岛素样生长因子结合蛋白-3(IGFBP-3)在非小细胞肺癌(non-small cell lung cancer,NSCLC)患者外周血清中的含量和肺癌组织局部的表达情况,探讨IGF-1和IGFBP-3与NSCLC发生发展的关系及其在NSCLC辅助诊断、危险性预测和治疗中的临床意义。方法运用酶联免疫吸附法(ELISA)检测肺癌组和对照组患者外周血血清中IGF-1、IGFBP-3的水平;运用免疫组化方法检测肺癌组和对照组患者肺组织标本的IGF-1与IGFBP-3表达情况。结果肺癌组血清中IGF-1表达高于对照组(P<0.05),肺癌组血清中IGFBP-3的表达显著低于对照组(P<0.05),IGF-1在肺癌组织中的表达强于对照组(P<0.05),IGFBP-3在肺癌组织中的表达弱于对照组(P<0.05)。结论 NSCLC患者血清IGF-1、IGFBP-3表达在非小细胞肺癌的发生、发展及远处转移中有重要作用,检测其水平变化对肺癌的诊断、判断预后有重要意义。
