While certain associations between specific ADs, such as pancreatitis, and PC have long been well confirmed, population\u2010focused research investigating the broader spectrum of ADs and their relationship with PC risk remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We implemented a cohort study based on population data to analyze the relationships between ADs and PC susceptibility. Diagnostic information on 43 ADs was obtained from the Swedish Inpatient Register (1964\u20132018), while cancer incidence and mortality data were sourced from the National Cancer Registry and Cause of Death Register starting in 1997. Relative cancer risks were quantified using standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Within the study's total population of 16.4 million, 1.1 million cases of ADs were identified, and 3257 patients were later diagnosed with PC accounting for 5.42% of all cancer cases in the cohort. The SIRs for PC in patients with ADs were 1.24 (men) and 1.19 (women); 12 ADs were positively correlated with the incidence of PC. The SMRs for PC in patients with ADs were 1.28 (men) and 1.22 (women); 15 ADs were positively correlated with PC mortality. When the follow\u2010up time was less than 1\u2009year, the overall risk of PC in patients with ADs was 3.88; over 10\u2009years, the risk reached 1.12.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We have newly discovered the relationship between several ADs and the risk of PC incidence and mortality, including discoid lupus erythematosus, lupoid hepatitis, giant\u2010cell arteritis, and rheumatic fever.
