Is this trial a fit for you?

Likely a good fit

Adults (18+) with diagnosed Crohn disease or ulcerative colitis who require screening colonoscopy for dysplasia and meet the specified disease and extent criteria.

Probably not a fit

Patients with ileal Crohn disease or rectal ulcerative colitis, or those undergoing therapeutic endoscopy without prior or ongoing follow-up at a participating center, may not benefit from study findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter observational study focusing on IBD patients who require colonoscopy for dysplasia. It aims to characterize dysplastic lesions and stratify evolving colorectal cancer risk in Crohn disease and ulcerative colitis. The study collects endoscopic and clinical data to understand patterns of lesion development, persistence, and recurrence after endoscopic management. No intervention is specified within the protocol; data collection will inform future risk stratification and management strategies. The findings could support more personalized surveillance approaches for IBD-associated dysplasia.

Why it matters

Potential benefit: If successful, the study could improve risk stratification and guide personalized colonoscopy intervals and management for IBD patients with dysplasia.

How similar studies have gone: Prior work suggests evolving endoscopic techniques and closer surveillance can reduce progression risk, but this specific observational characterization of evolving dysplasia risk in IBD is relatively novel.
