CUG-binding protein 1 (CUGBP1) expression and prognosis of non-small cell lung cancer

Background and aims

Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. As CUGBP1 may also play a great role in tumor genesis and deterioration, the purpose of this study was to detect the expression of CUGBP1 mRNA and CUGBP1 and assess the prognostic significance of CUGBP1 in NSCLC.

Methods

Expression of CUGBP1 mRNA and CUGBP was detected by Semi-quantitative PCR and Immunohistochemistry, respectively, from 57 NSCLC patients. The percentage of CUGBP1 mRNA and CUGBP1 expression was correlated with clinical characteristics using χ ² test. The prognostic significance was assessed by univariate and multivariate analyses in the Cox hazard model.

Results

The expression of CUGBP1 mRNA and CUGBP1 was over-expressed in cancer group and was correlated with TNM stage and Differentiation. By both univariate and multivariate survival analyses, CUGBP1 expression (P = 0.0074, HR = 3.701, 95 % CI 1.420–9.648), TNM-stage (HR = 4.043, 95 % CI 2.098–7.794) and age (HR = 3.207, 95 % CI 1.544–6.664) were noted to be independent indicators of a shorter postsurgical survival.

Conclusions

The expression of CUGBP1 independently predicted a shorter postsurgical survival in NSCLC.
