Detecting recurrent colorectal lesions using mutation analysis and clinical phenotype

Development and Clinical Utility of a New Method to Identify Patients With Risk of Recurrent Colorectal Lesions and Personalization of Their Surveillance Based on Mutation Burden and Clinical-pathological Phenotype

Observational Military University Hospital, Prague · NCT05929365

This study is testing if looking at genetic changes in colorectal polyps can help doctors better predict and monitor the risk of new lesions in patients who have had high-risk adenomas removed.

What this trial studies

This observational study aims to identify the risk of recurrent colorectal lesions in patients by analyzing somatic mutations in their colorectal polyps. It will involve mutation analysis of all synchronous lesions in 200 patients who have had high-risk adenomas removed, followed by surveillance colonoscopies at 1, 3, and 5 years to monitor for metachronous lesions. The study will correlate mutation profiles with clinical and histopathological parameters to optimize surveillance intervals for high-risk patients.

Who should consider this trial

Good fit: Ideal candidates are patients who have had colorectal polyps larger than 10mm removed and are willing to participate in the study.

Not a fit: Patients with hereditary colorectal cancer syndromes or severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective surveillance strategies for patients at high risk of colorectal cancer.

How similar studies have performed: While similar approaches have been explored, this study's specific focus on mutation analysis for surveillance intervals is relatively novel.
