Cure8 research brief
People with UC and PSC may develop colorectal neoplasia earlier, at younger ages, and more often in the right colon; this could affect the timing and approach to colonoscopic surveillance.
Adults with ulcerative colitis, especially those diagnosed with primary sclerosing cholangitis; gastroenterologists and clinicians managing IBD surveillance; patients and caregivers interested in colorectal cancer risk and screening.
This retrospective nationwide Japanese study enrolled 808 patients with UC-associated colorectal neoplasia (UCAN) from 1983–2020, including 26 with PSC-UCAN and 782 without PSC. Patients with PSC developed UCAN at a younger age and after a shorter UC duration, and lesions were more often located in the right colon.
The PSC-UCAN group showed a higher proportion of early-stage cancers and a lower proportion of high-grade dysplasia, while 10-year overall and cancer-specific survival were similar between groups.
The authors conclude that people with PSC and UC may benefit from earlier initiation of surveillance colonoscopy, given the tendency toward earlier and right-sided neoplasia.
The report is a retrospective nationwide cohort with a small PSC subgroup (26 patients). Findings come from the article abstract; details such as surveillance interval recommendations, pathology protocols, or management changes are not provided in the abstract.

Preneoplastic (adenomatous and serrated) polyps can be precursors to colorectal cancer, so knowing how common they are and what raises risk may affect surveillance planning for people with ulcerative colitis.
