t-initiated health checkup program (2012–2017), which collected lifestyle data, anthropometric measurements, and biochemical tests. Follow-up continued until 2021, with data linkage to National Cancer and Death Registries to ascertain the occurrence of cholangiocarcinoma and obtain vital status information. Fine and Gray models accounted for competing risks. During 35,879,371 person-years of follow-up, 6,117 cholangiocarcinoma cases were identified, with an incidence rate of 17.05 (95% CI: 15.90-18.20) per 100,000 person-years. Individuals with metabolic syndrome had significantly higher incidences of both intra- and extra-hepatic cholangiocarcinoma (p<0.0001). The multivariate-adjusted hazard ratio (HR) for cholangiocarcinoma among those with metabolic syndrome was 1.20 (1.14-1.27). Stratification analyses by age, sex, liver enzyme levels, and comorbidities consistently demonstrated an increased cholangiocarcinoma risk among individuals with metabolic syndrome.
