ABSTRACT:

Background/aims

We conducted a nationwide population-based study to investigate incidence rates of colorectal and biliary cancers according to accompanying primary sclerosing cholangitis in Korean ulcerative colitis patients.

Methods

We used the Health Insurance Review and Assessment claim database from January 2007 to April 2020. Standardized incidence ratios of colorectal and biliary cancers in ulcerative colitis patients were calculated.

Among 35,189 newly diagnosed ulcerative colitis patients, 1,224 patients were diagnosed with primary sclerosing cholangitis.
