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.
