Capsule camera screening of the small intestine for people with Lynch syndrome
Small Bowel Capsule Endoscopy for (Pre)Neoplastic Lesion Screening in Patients With Lynch Syndrome
This project looks back at past small-bowel capsule endoscopy exams to see if they detect precancerous lesions or early cancer in people with Lynch syndrome.

What this trial studies
The iCARE4Lynch project is a retrospective cohort of people carrying a pathogenic MMR gene variant who underwent at least one small-bowel capsule endoscopy between January 1, 2000 and December 31, 2024. The primary aim is to estimate how well a first (index) capsule endoscopy detects small-bowel precancerous and cancerous lesions, while recording technical performance and adverse events. Secondary analyses include the performance of subsequent capsule exams, age at lesion diagnosis, therapeutic impact of detected lesions, and lesion frequency by specific MMR gene. Data come from routine clinical records at participating iCARE centers and no additional procedures are required for participants.
Who should consider this trial
Good fit: Ideal candidates are people with Lynch syndrome confirmed by a pathogenic MMR gene variant who had at least one small-bowel capsule endoscopy and did not oppose reuse of their clinical data.
Not a fit: People without a documented pathogenic MMR variant, those who never had capsule endoscopy at a participating center, or those who refuse reuse of their healthcare data would not be included and are unlikely to benefit directly.
Why it matters
Potential benefit: If positive, the findings could help doctors detect small-bowel precancers earlier in people with Lynch syndrome and inform better screening recommendations.
How similar studies have performed: Capsule endoscopy is proven for detecting small-bowel lesions in other clinical contexts, but its specific usefulness for screening people with Lynch syndrome is limited and not well established.
