Background: This study is aimed to investigate the association between polymorphisms in UGT2B17 and the risk of developing pancreatic cancer in Chinese Han population.
Methods: A hospital-based case-control study was conducted, and 1579 healthy controls and 406 pancreatic cancer patients were enrolled. Real-time PCR was applied to identify the genetic polymorphisms in the subjects, and multivariable logistic regression analysis was performed to investigate the association between UGT2B17 polymorphisms and susceptibility to pancreatic cancer.
Results: The prevalence of the UGT2B17 del/del, del/ins, and ins/ins in cases were 72.9%, 24.0%, and 3.1%, respectively, and in controls 66.6%, 30.7%, and 2.7%, respectively. Multivariable logistic regression revealed that, compared with the del/del genotype, the del/ins genotype in UGT2B17 is related to a significant reduction in pancreatic cancer risk (OR = 0.77, 95% CI = 0.60 - 0.99; P = 0.04). In the female subjects, compared with the del/del genotype, the del/ins genotype was related to a substantial reduction in pancreatic cancer risk (OR = 0.59, 95% CI = 0.39 - 0.90, P = 0.01).
Conclusions: All these results indicate a higher ratio of UGT2B17 deletion polymorphisms in Asians. UGT2B17 deletion polymorphisms are associated with the risk of developing pancreatic cancer in Chinese Han population, especially in the female population.
