摘要: 目的 探讨CCDC8和TGF-β1在非小细胞肺癌中的表达及其与临床病理特征的关系。方法 比较TCGA数据库正常肺组织与肿瘤组织中CCDC8和TGF-β1的表达量,分析非小细胞肺癌中CCDC8和TGF-β1表达的相关性。免疫组织化学染色检测204例常规石蜡包埋非小细胞肺癌组织CCDC8、TGF-β1表达并分析其与肺癌临床病理特征关系。利用Kaplan-Meier法绘制生存曲线,应用Cox回归分析CCDC8、TGF-β1表达与患者总生存期(OS)的关系。结果 TCGA数据中正常肺组织CCDC8与TGF-β1表达较肿瘤组织中高(P<0.05),非小细胞肺癌患者CCDC8表达与TGF-β1表达呈正相关(P<0.0001);鳞癌中CCDC8低表达患者OS长(HR=1.32,P=0.0437)。204例非小细胞肺癌组织中,CCDC8表达与TGF-β1表达呈正相关(P=0.023)。Cox单因素分析鳞癌中CCDC8表达与OS有关(P=0.013);而CCDC8和TGF-β1表达与腺癌患者生存无关(P=0.967,P=0.816)。Cox多因素分析TNM分期、CCDC8表达是肺鳞癌患者预后因子(P=0.016)。结论 非小细胞肺癌中CCDC8表达与TGF-β1表达正相关,CCDC8可能是肺鳞癌患者预后因子。

Abstract: Objective The aim of this study was to investigate the expression of CCDC8(coiled-coil domain containing 8,P90)and transforming growth factor β 1(TGF- β1)in none small cell lung cancer(NSCLC),and its relationship with clinicopathological characteristics.Methods The expression of CCDC8 and TGF-β1 in NSCLC was analyzed in the TCGA database.The Kaplan-Meier curve was plotted to analyze its correlation with survival of patient.The expression of CCDC8 and TGF-β1 in 204 cases of conventional paraffin-embedded NSCLC was detected by immunohistochemical staining and their relationship with clinicopathological features of NSCLC was analyzed.The relationship between the expression of CCDC8 and TGF-β1 and the overall survival(OS)of patients was analyzed by Cox regression.Results The expression of CCDC8 in NSCLC patients was positively correlated with TGF-β1 expression in the TCGA data(P<0.05).OS was low in patients with the low expression of CCDC8(HR=1.32,P=0.0437).In 204 NSCLC tissues,CCDC8 expression was positively correlated with TGF-β1 expression(P=0.023).Cox univariate analysis of CCDC8 expression in NSCLC was associated with OS(P=0.013);whereas the expression of CCDC8 and TGF-β1 was not associated with survival in patients with NSCLC(P=0.967,P=0.816).Cox multivariate analyses of TNM staging and CCDC8 were prognosis factors in patients with NSCLC(P=0.016).Conclusion The expression of CCDC8 is correlated the expression of TGF-β1 in NSCLC.CCDC8 may be a prognostic factor for patients with NSCLC.
