摘要:

目的 研究Caveolin-1在非小细胞肺癌(NSCLC)中的表达,探讨Caveolin-1的表达与肺癌表皮生长因子受体(EGFR)突变的关系。方法 运用免疫组织化学法检测哈尔滨医科大学附属肿瘤医院40例NSCLC组织中Caveolin-1表达,同时应用ARMS-qPCR方法检测EGFR突变情况,并结合患者的临床病理特征和相关性进行分析。结果 Caveolin-1在NSCLC组织中阳性表达率显著低于正常肺组织,NSCLC组织中Caveolin-1表达与组织学类型相关,同时与EGFR突变呈负相关,差异有统计学意义(P<0.05)。结论 Caveolin-1表达与EGFR突变在NSCLC中呈负相关,与组织学类型密切相关,可能成为诊断和判定NSCLC临床预后的重要分子指标。

Abstract:

Objective This study aims to examine expression of Caveolin-1 in non smoking cell lung cancer(NSCLC)and to discusses the relationship between expression of Caveolin-1 and the Epidermal growth factor receptor mutations.Methods Immunohistochemical staining was used to determine the Caveolin-1 expression and ARMS-qPCR was used to measure EGFR mutations in 40 cases of lung cancer tissue.The clinical pathological characteristics and correlations in patients were analyzed.Results The expression of Caveolin-1 in human lung cancer was significantly lower than that in normal lung tissue,and negatively correlated with EGFR mutations,which was statistically significant.Conclusion Caveolin-1 expression is negatively correlated with EGFR mutations in non-small cell lung cancer and related to the histologic type.Caveolin-1 may be a molecular target for diagnosis and judgment of NSCLC.

Key words: Caveolin-1, EGFR mutation, Non-small cell lung carcinoma, Immunohistochemical
