This is also true of hepatobiliary cancers, which include hepatocellular cancer (HCC) and rarer entities of gallbladder cancer (GBC), intra\u2010 and extrahepatic cholangiocarcinoma (iCCA and eCCA), and ampullary cancer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Diagnostic data on 43 autoimmune diseases were collected from the Swedish Inpatient Register from 1987 to 2018, and cancer data were derived from the national cancer registry from 1997 onward. Relative risks were expressed as standardized incidence ratios (SIRs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In a population of 13.6\u00a0million, 1.1\u00a0million autoimmune diseases were diagnosed and subsequent hepatobiliary cancer was diagnosed in 3191 patients (17.2% of cancers). SIRs for HCC were 2.73 (men) and 2.86 (women), 3.74\/1.96 for iCCA, 2.65\/1.37 for GBC, 2.38\/1.64 for eCCA, and 1.80\/1.85 for ampullary cancer. Significant associations between autoimmune disease and HCC were observed for 13 autoimmune diseases, with the highest risks being for autoimmune hepatitis (48.92\/73.53, men\/women) and primary biliary cirrhosis (38.03\/54.48). GBC was increased after six autoimmune diseases, with high SIRs for ulcerative colitis (12.22\/3.24) and men with Crohn disease (9.16). These autoimmune diseases were also associated with a high risk of iCCA, which had seven other associations, and eCCA, which had five other associations. Ampullary cancer occurrence was increased after four autoimmune diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>An autoimmune disease is a common precursor condition for hepatobiliary cancers.
