Testing gut microbiome for colorectal cancer screening
A Non-invasive Gut Microbiome-based Diagnostic Tool for the Screening of Colorectal Cancer
This study is trying to see if testing the gut bacteria of people aged 50-74 who have a positive stool test can help find colorectal cancer earlier and reduce the need for unnecessary colonoscopies.

What this trial studies
This observational study aims to develop a diagnostic tool based on gut microbiome testing to identify colorectal cancer (CRC) and advanced colorectal adenomas. It focuses on patients aged 50-74 who are participating in the national CRC screening program and have tested positive for fecal immunochemical testing (FIT). The study leverages evidence that specific alterations in the gut microbiome are associated with CRC, aiming to improve diagnostic accuracy and reduce unnecessary colonoscopies. By identifying microbial signatures that differentiate CRC patients from healthy individuals, the study seeks to enhance early detection methods.
Who should consider this trial
Good fit: Ideal candidates are patients aged 50-74 who are part of the national CRC screening program and have a positive FIT result.
Not a fit: Patients who are unfit for colonoscopy or have other oncological conditions or severe gastrointestinal diseases may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to more accurate and non-invasive screening for colorectal cancer, potentially reducing mortality rates.
How similar studies have performed: While the approach of using microbiome-based biomarkers for CRC screening is supported by emerging evidence, this specific study represents a novel application in clinical practice.
