Association Studies of ERCC2 rs13181 Polymorphism with Pancreatic Cancer Susceptibility.

Although the ERCC2 gene rs13181 polymorphism is involved in the pancreatic cancer pathogenic mechanism, there is no consistent finding. This meta-analysis aimed to determine the association between ERCC2 rs13181 polymorphism and pancreatic cancer. Related articles were searched against the PubMed database in a retrospective way. Additionally, the combined odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were calculated using the random- or fixed-effects model. Altogether, seven articles regarding ERCC2 gene rs13181 polymorphism were enrolled. The combined ORs regarding the relationship of ERCC2 rs13181 polymorphism with pancreatic cancer incidence showed significant differences in each genetic model (C vs. A: OR = 1.14, 95% CI = 1.04-1.26; CC vs. AA: OR = 1.53, 95% CI = 1.24-1.90; AC vs. AA: OR = 1.06, 95% CI 0.92-1.22; recessive model: OR = 1.50, 95% CI = 1.22-1.84; dominant model: OR = 1.16, 95% CI = 1.02-1.32). Additionally, we performed subgroup analysis stratified by race, which revealed that ERCC2 rs13181 polymorphism increased the risk of pancreatic cancer in Asian populations. This work suggests that the ERCC2 gene rs13181 polymorphism is related to pancreatic cancer risk in Asians.
