Lack of Association between the CDH1 -160C>A Polymorphism and Risk of Gastrointestinal Cancer - a Meta-Analysis.
E-cadherin (CDH1) genetic variations alter gene transcriptional activity of epithelial cells in vitro and may cause susceptibility to various cancers. Associations of CDH1 -160C>A polymorphism with various cancers have been widely reported. However, the results are controversial and inconsistent. To derive a more accurate estimation of the relationship, a meta-analysis was performed with regard to gastrointestinal (GI) cancer risk. Eligible studies were identified through a search of PubMed database until December 2015. Associations between the CDH1 -160C>A polymorphism and GI cancer risk was considered by odds ratios (ORs) together with their 95% confidence intervals (CIs). A total of 31 studies including 11,606 cases and 12,655 controls were involved in this meta-analysis. Overall, this meta-analysis showed no association between CDH1 -160C>A polymorphism and GI cancer risk (A vs. C: OR = 1.08, 95%CI = 0.98-1.18, P = 0.086;CA vs. CC: OR = 1.09, 95%CI = 0.97- 1.22, P = 0.118; AA vs. CC: OR = 1.10, 95%CI = 0.89-1.35, P = 0.356; AA vs. CC + CA: OR = 1.06, 95%CI = 0.96-1.18, P = 0.207; CA+AA vs. CC: OR = 1.01, 95%CI = 0.84-1.22, P = 0.89). In subgroup analysis, similar results were found. In conclusion, this meta-analysis has demonstrated that there is a lack of association of the CDH1-160C>A polymorphism with GI cancer susceptibility.
