Association of interleukin-10 , , and interleukin-6 polymorphisms with squamous cell carcinoma risk: A meta-analysis.

The relationship between interleukin ()-10 and gene polymorphisms and squamous cell carcinoma (SCC) has been demonstrated but with inconsistent conclusions. The aim of this study was to evaluate the potential associations of gene polymorphisms and the SCC risk. PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure, China Biomedical Database, WanFang, and China Science and Technology Journal Database databases were searched for articles reporting the correlations of and gene polymorphisms with the SCC risk. Odds ratio and 95% confidence interval were calculated using Stata Version 11.2. Meta-regression, sensitivity, and publication bias were analyzed. False-positive reporting probability and Bayesian measure of the false-discovery probability were used to explore the credibility of the calculation. Twenty-three articles were included. The polymorphism showed a significant correlation with the SCC risk in the overall analysis. Studies pooled by ethnicity revealed that the polymorphism reduced the SCC risk in the Caucasian population. The results of this study suggest that the polymorphism may confer a genetic susceptibility to SCC, particularly oral SCC, in Caucasians. However, the or polymorphism was not significantly associated with the SCC risk.
