Examining bile acids and microbiome changes in early colorectal cancer development

Bile Acids and Microbiome - Possible Novel Progression Factors and Diagnostic Indicators in Early Colorectal Carcinogenesis

Observational Vilnius University · NCT06502704

This study is trying to see how changes in bile acids and gut bacteria might affect the development of colorectal cancer in adults who have polyps or cancer.

What this trial studies

This observational study investigates the relationship between bile acid metabolism and microbiome composition in patients with colorectal neoplasms, including small and large adenomas and invasive colorectal cancer. The study aims to understand how these changes may contribute to the progression from adenoma to carcinoma. Adult participants referred for colonoscopy will provide fecal samples for analysis, alongside healthy controls, to identify potential biomarkers associated with colorectal cancer development.

Who should consider this trial

Good fit: Ideal candidates include adults with clinical indications for colonoscopy who have been diagnosed with small or large adenomas or invasive colorectal cancer.

Not a fit: Patients who are pregnant, immunocompromised, or have a history of colorectal diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and early detection strategies for colorectal cancer.

How similar studies have performed: While the relationship between bile acids, microbiome, and colorectal cancer is being explored, this specific approach is relatively novel and has not been extensively tested.
