Predicting recurrence of high-risk colorectal polyps using microbiota and metabolites

Development and Validation of Microbiota and Metabolite-based Prediction Model for Recurrence of High-risk Colorectal Polyps After Polypectomy

Observational Peking Union Medical College Hospital · NCT06957626

This study is trying to see if the bacteria and substances in the gut can help predict if high-risk colorectal polyps will come back after they've been removed.

What this trial studies

This study analyzes the characteristics of intestinal microbiota in patients who have undergone polypectomy for high-risk colorectal polyps. It aims to understand the relationship between microbial communities and the recurrence of these polyps, which could provide insights into the etiology of adenoma recurrence. By developing a prediction model based on microbiota and metabolites, the research seeks to enhance patient management and outcomes following polypectomy.

Who should consider this trial

Good fit: Ideal candidates are patients aged 40-75 years who have at least one high-risk colorectal polyp and are undergoing colonoscopy.

Not a fit: Patients with severe physical diseases, previous gastrointestinal surgeries, or existing colorectal cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a predictive tool that helps identify patients at higher risk for polyp recurrence, allowing for more tailored surveillance and intervention strategies.

How similar studies have performed: While the specific approach of using microbiota and metabolites for prediction is novel, similar studies have shown promise in understanding the role of microbiota in colorectal health.
