Background: Previous studies have reported that nuclear receptor subfamily 5, group A, member 2 (NR5A2) polymorphisms (rs3790843 G>A, rs3790844 T>C, rs12029406 C>T) are associated with the risk of pancreatic cancer. However, the results of epidemiological investigations are still controversial. In order to explore its potential attributing factors, we pooled the updated literatures to evaluate the association between NR5A2 polymorphism and the risk of pancreatic cancer in this meta-analysis. Materials and methods: Databases such as PubMed, Google Scholar and China National Knowledge Infrastructure were searched for eligible articles following strict inclusion and exclusion criteria (updated to November 18, 2017). Odds ratios (ORs) and 95% C Is were computed to assess the intensity of association. In addition, heterogeneity, sensitivity analysis and publication bias were explored. All statistical analyses were conducted by STATA 14.0. Results: Our results showed that the rs3790843 (GA vs GG: OR=0.86, CI=0.76-0.98, P=0.992;GA+AA vs GG: OR=0.83, CI=0.73-0.94, P=0.950;A vs G: OR=0.85, CI=0.78-0.93, P=0.802), rs3790844 (CC vs TT: OR=0.65, CI=0.54-0.78, P=0.617;CC vs TT+CT: OR=0.73, CI=0.62-0.85, P=0.742;C vs T: OR=0.78, CI=0.73-0.84, P=0.555) and rs12029406 (TT vs CC: OR=0.73, CI=0.61-0.89, P=0.483;TT vs CC+CT: OR=0.78, CI=0.66-0.92, P=0.648;T vs C: OR=0.87, CI=0.79-0.95, P=0.837) polymorphisms were associated statistically with the risk of pancreatic cancer. Furthermore, the results of subgroup analysis showed that rs3790843 and rs3790844 polymorphisms were especially related to the risk of pancreatic cancer in Caucasian population. Conclusion: Our results revealed that NR5A2 may have a protective effect on pancreatic cancer. However, more well-designed researches are needed to verify the relationship between NR5A2 polymorphisms and the risk of pancreatic cancer.
