Cure8 research brief
The study suggests that mucosal abnormalities (low-grade dysplasia, adenomas) are stronger predictors of colorectal cancer risk in UC than inflammation or disease extent, which could influence how surveillance is targeted.
Adults with ulcerative colitis, clinicians who perform endoscopic surveillance, researchers studying CRC risk in IBD, and patients on biologic or immunomodulator therapy.
The study followed a very large incident UC cohort (about 90,780 subjects equivalent) with median 15 years of follow-up and analyzed 566 CRC cases versus 720 subcohort members using weighted multivariable models.
Key findings reported: pancolitis carried higher CRC risk than proctitis; low-grade dysplasia and adenomas conferred substantially higher CRC rates; inflammation severity showed no consistent association; and biologic or immunomodulator treatments were not associated with statistically significant CRC risk reduction.
How this might affect care If confirmed by further work, these results suggest surveillance strategies that focus on detecting mucosal abnormalities (dysplasia/adenomas) could be more informative for CRC risk stratification than relying primarily on inflammation severity or extent.
The authors note their findings do not support prevailing surveillance recommendations, indicating potential implications for guidelines and practice.

Obese patients with FibroScan-detected steatosis in this cohort had a high frequency of colitis and some cases of IBD, dysplasia, and cancer, which could affect screening and symptom evaluation decisions.
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.
The study will prospectively evaluate how often dysplasia occurs, how lesions look and behave after endoscopic resection, and what factors predict local or distant recurrence—information that could change surveillance...
