摘要 目的研究Wnt/β-catenin信号通路中关键分子Wnt1、β-catenin及Sox-2在非小细胞肺癌(NSCLC)组织中的表达,探讨其与患者临床特征的关系。方法采用免疫组织化学SP法检测NSCLC组织和正常肺组织中Wnt1、β-catenin及Sox-2蛋白的阳性表达率,并分析其与患者临床特征的关系,采用Kaplan-Meier法分析β-catenin表达与NSCLC患者中位生存期的关系。结果 NSCLC组织中Wnt1、β-catenin及Sox-2蛋白阳性表达率明显高于正常肺组织(P<0.05),Wnt1、Sox-2的表达与淋巴结转移和TNM分期相关,β-catenin的表达与病理类型及组织分化程度相关,β-catenin阳性表达患者中位生存期低于阴性表达患者(P<0.05)。结论Wnt/β-catenin信号通路中关键分子Wnt1、β-catenin及Sox-2在NSCLC组织中的阳性表达率较正常肺组织高,并且其表达水平与患者临床分期和预后有关联。
