AbstractMany studies have suggested an association between 9p24 rs719725 polymorphism and colorectal cancer (CRC) risk, but with inconsistent results. This meta-analysis aimed to summarise the overall association of rs719725 polymorphism with CRC risk. Nine eligible articles with 21 case-control studies (16015 CRC patients and 19341 controls) on the rs719725 polymorphism and CRC susceptibility from four electronic databases (Web of Science, PubMed, SinoMed, and EMBASE) were retrieved and analysed. The association was evaluated with publication bias, pooled OR (odds ratio), and corresponding 95% CI (confidence interval). The pooled results indicated a significant association between the increased CRC risk and rs719725 polymorphism in dominant ([OR] 1.220, [95%CI] 1.161-1.282), recessive (1.166, 1.102-1.234), allele (1.142, 1.102-1.184), homozygous (1.306, 1.212-1.406), and heterozygous (1.18, 1.129-1.234) genetic models. The ethnicity-stratified analyses found a consistently significant association. In the stratification analysis with the source of controls, such significant association was also detected amid the population-based studies under the four former genetic models. Taken together, this meta-analysis indicates that rs719725 genetic variants are associated with an increased risk of CRC among Caucasians and population-based studies. Further relevant research is warranted to confirm these findings. Key Words: Colorectal cancer, rs719725, Polymorphism, Meta-analysis, Stratification analysis.
