Epidemiological studies have investigated the association between MDM2 promoter SNP 309 (T/G) and endometrial cancer susceptibility. However, the results are still controversial. To obtain a more precise estimate of the relationship, we conducted a meta-analysis of 1,001 cases and 1,889 controls from 6 published case-control studies (one of five articles contains two studies) to estimate the effect of SNP309 on endometrial cancer risk. The strength of association between MDM2 SNP309 and endometrial cancer susceptibility was assessed by calculating pooled odds ratios (ORs) with 95% confidence intervals (CIs). When all the eligible studies were pooled in the meta-analysis, we found that elevated endometrial cancer risk was significantly associated with GG variant genotype, however, heterozygous genotype TG seemed to be only a minor modifier on endometrial cancer risk (for GG vs. TT, OR = 1.54, 95% CI = 1.21-1.95, P = 0.0004; for TG vs. TT, OR = 0.96, 95% CI = 0.81-1.14, P = 0.66; for dominant model, OR = 1.09, 95% CI = 0.93-1.29, P = 0.29; for recessive model, OR = 1.65, 95% CI = 1.33-2.04, P < 0.00001). Overall, the meta-analysis suggested that the GG genotype of MDM2 SNP309 was significantly associated with the increased endometrial cancer risk.
