BRCA1 missense polymorphisms are associated with poor prognosis of pancreatic cancer patients in a Chinese population.

ABSTRACT: Pancreatic cancer is a highly lethal disease with limited prognostic marker. BRAC1 and BRCA2 are two classic tumor suppressor genes which play an important role in DNA repair. Somatic mutations and germline genetic variants on BRCA1/2 have been found associated with the tumorigenesis of pancreatic cancer. However, the correlations between BRCA1/2 polymorphism and pancreatic cancer prognosis remained unknown. In this study, we genotyped three tag missense variants on BRCA1/2 in 603 sporadic pancreatic cancer patients in a Chinese population. We found rs1799966 on BRCA1 was associated with poor prognosis of pancreatic cancer patients with hazard ratio being 1.23 (95% CI: 1.09-1.40, P = 0.0010). Further stratification analyses showed that significant correlation was particularly in locally ad
