Tailored scope schedule may cut cancer risk in FAP patients
NCT ID NCT04677998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a personalized surveillance plan for people with familial adenomatous polyposis (FAP), a condition that raises the risk of polyps and cancer in the stomach and duodenum. Participants will have endoscopic exams at intervals tailored to their polyp severity, ranging from every 3 months to every 5 years. The goal is to see if this approach reduces the chance of advanced polyps or cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- personalized surveillance and intervention protocol
- What this could lead to
- If successful, this could provide a tailored monitoring schedule that reduces the risk of advanced polyps and cancer in people with FAP.
- What could go wrong
- This is an observational-style study without a control group, so it may not prove the protocol is better than standard care. Results depend on long-term follow-up.
