Abstract ObjectiveTo investigate the association between the vascular endothelial growth factor(VEGF)gene+936C/T polymorphisms and colorectal cancer(CRC)risk.MethodsRelevant published case-control studies were searched in PubMed,Embase and Medline databases,and all documents were updated to October 2016.A comprehensive meta-analysis was then performed with Review Manager 4.2 and Stata 11.0 software in this work.ResultsFinally 10 studies including 2860 cases and 3080 controls were brought into our meta-analysis.The association between VEGF+936C/T polymorphisms and CRC risk were calculated with OR and their corresponding 95%CI,and stratified analysis was also conducted with respect to ethnicity.Combined analysis revealed that no significant association between VEGF+936C/T polymorphismandCRCriskwasidentifiedinallcomparisonmodelsincludingTallele vs.Callele[OR=1.04,95%CI(0.87,1.25), P=0.63],CT+TT vs.CC[OR=1.06,95%CI(0.86,1.30),P=0.61],TT vs.CC+CT[OR=1.10,95%CI(0.85,1.41),P=0.47],and TT vs. CC[OR=1.17,95%CI(0.91,1.52),P=0.22].Moreover,a similar result was obtained in the subgroup analysis that no significant association with CRC risk was found in all comparison models of VEGF+936C/T polymorphism in both Caucasian and Asian populations.ConclusionIt has been proved that VEGF+936C/T polymorphism might not be a risk factor for colorectal cancer,but further studies with larger sample sizes are required to make a better assessment of above association.
