Gallstones, cholecystectomy, and cancer risk: an observational and Mendelian randomization study
This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50–4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17–5.16), kidney cancer (aOR=2.04, 95% CI 1.05–3.94), and bladder cancer (aOR=2.23, 95% CI 1.01–5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12–2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29–4.49), colorectal cancer (aOR=1.83, 95% CI 1.18–2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11–6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.
