IntroductionThe association between IL-16 rs1131445 polymorphism and cancer risk is not consistent or even contradictory, this meta-analysis aims to investigate the role of IL-16 gene rs1131445 polymorphisms in the risk of cancer.Evidence AcquisitionA comprehensive online search was conducted in PubMed, EMBASE and CNKI databases to identify eligible studies. The case-control studies related IL-16 rs1131445 C/T polymorphism with the cancer susceptibility were selected according to the inclusion and exclusion criteria. After extracting the basic data information and quality of literature evaluation, the meta-analysis was performed by using STATA 12.0 software, with calculating odds ratio and 95% confidence interval, and further subgroup analysis, literature publication bias test and sensitivity analysis.Evidence SynthesisThere are totally 1677 cases and 1989 non-tumor controls finally involved. Meta-analysis showed that there are statistical correlations between the IL-16 rs1131445 C/T polymorphism and the cancer risk in Asian populations (TS vs. C, OR=0.80, 95%CI: 0.73-0.88; TT vs. TC, OR=0.75, 95%CI: 0.65-0.87; TT vs. CC, OR=0.69, 95% CI: 0.56-0.84; CC+TC vs. TT, OR=1.36, 95%CI: 1.19-1.55; CC vs. TC+TT, OR=1.27, 95%CI: 1.05-1.53) (all P<0.05).ConclusionsIL-16 rs1131445 C/T polymorphism is related to the susceptibility to cancer in Asians, suggesting that the C allelic gene of rs1131445 is significantly associated with an increasing cancer risk.
