Abstract

This study was designed to determine the levels of survivin expression and identify its clinical significance as a prognostic factor for stage III non-small cell lung cancer (NSCLC). A total of 210 cases of stage III NSCLC were collected and the expression levels of survivin and vascular endothelial growth factor A (VEGF-A) in tumor tissues were investigated using immunohistochemistry (IHC). The medical records of the patients were reviewed to determine the association with clinical course. Of the 210 NSCLC tissues, 112 (53.3%) cases demonstrated positive expression of survivin protein. Coexpression of survivin and VEGF-A was identified. The 5-year survival rate of patients with positive survivin expression was significantly lower compared with the survivin-negative cancer patients (P<0.05). The expression of survivin in NSCLC correlated with tumor size. Survivin and VEGF-A were independent prognostic factors of stage III NSCLC. Survivin protein is a valuable marker of prognosis in stage III NSCLC patients.

摘要

本研究旨在确定生存素的表达水平,并确定其作为Ⅲ期非小细胞肺癌(NSCLC)预后因素的临床意义。共收集210例Ⅲ期NSCLC病例,采用免疫组织化学(IHC)方法检测肿瘤组织中生存素和血管内皮生长因子A(VEGF-A)的表达水平。回顾患者的病历以确定其与临床病程的相关性。在210例NSCLC组织中,112例(53.3%)生存素蛋白呈阳性表达。发现生存素与VEGF-A共表达。生存素表达阳性患者的5年生存率显著低于生存素阴性的癌症患者(P<0.05)。NSCLC中生存素的表达与肿瘤大小相关。生存素和VEGF-A是Ⅲ期NSCLC的独立预后因素。生存素蛋白是Ⅲ期NSCLC患者预后的一个有价值的标志物。
