摘要:: Despite epidemiologic data, definitive evidence for the role of gallstones as a cause for gallbladder cancer is lacking. The goal of this study was to evaluate the association between gallstones, determined by ultrasound, and the risk of gallbladder cancer mortality in a large study of Korean men and women. In addition, the association between gallstones and cholecystectomy, and risk of hepatobiliary cancer mortality was investigated.,A cohort study was performed for 396,720 South Korean men and women who underwent a health checkup from 2002 to 2012. Hazard ratios for mortality outcomes were estimated using Cox-proportional hazards regression analysis. Vital status and cause of death assignment were based on linkage to the National Death Index of death certificate records.,From a total of 2,158,906.2 person-years of follow-up (median follow-up of 5.4 years), we identified 224 deaths from hepatobiliary cancer, comprising 174 cases of liver/intrahepatic bile ducts cancer, 20 cases of gallbladder cancer, and 30 cases of biliary tract cancer. Gallstones were significantly associated with increased risk of hepatobiliary cancer mortality, especially liver/intrahepatic biliary cancer, and gallbladder cancer mortality. The multivariable-adjusted hazard ratios (95% confidence intervals) for hepatobiliary cancer, liver/intrahepatic biliary cancer, and gallbladder cancer mortality comparing subjects having gallstones with those without gallstone disease were 2.74 (1.83-4.10), 2.34 (1.45-3.77), and 7.35 (2.60-20.8), respectively. Cholecystectomy was not significantly associated with hepatobiliary cancer mortality.,In this large cohort study, gallstones were associated with increased risk of hepatobiliary cancer mortality, especially liver/intrahepatic cancer, and gallbladder cancer mortality independent of potential confounders. Future studies with longer follow-up periods that include data on incident cancer cases should provide a more comprehensive view of the role of gallstones in cancer development.
