Makiuchi T, Sobue T, Kitamura T, et al. - Researchers undertook a population-based prospective cohort analysis in Japan, to determine the risk of biliary tract cancer (BTC) in correlation with meat and fish consumption. They used the Cox proportional hazard model to estimate hazard ratios and 95% confidence intervals. In this study, the enrolled men and women, of ages 45-74 years, were 43,177 and 49,323, respectively. These were observed for 607,757.0 person-years (men) and 728,820.3 person-years (women) until 2012, during which time 217 male and 162 female BTC cases were recognized. In Japan, a lower risk of BTC was observed in men who consumed more meat, especially red meat. There was no link between fish intake and BTC risk.
