Test stool DNA changes to screen or find colorectal cancer
Part of Cancer, Digestive system clinical trials.
This study checks whether a stool test that looks for tiny genetic signals can help detect colorectal cancer (or find it again after prior findings). You may be asked to provide a stool sample around the time you get a colonoscopy.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are being referred for a colonoscopy for screening, follow-up, or diagnosis
- Your age fits one of these groups: 50–75 (average risk), 30–80 with family history, or 18+ for surveillance/symptoms
- You may have one of these reasons for colonoscopy: screening, family history of colorectal cancer, prior polyps, prior colorectal cancer, or current bowel symptoms
- You can and are willing to give informed consent to join the study
- You do not have Lynch syndrome or a family history of Lynch syndrome
- You do not have certain bowel conditions or polyposis syndromes (including personal or family history of adenomatous/hamartomatous polyposis or serrated polyposis syndrome)

This study tests if a stool microbiome test can help find colorectal cancer early in people who already had a positive FIT screening test. You would give a stool sample and your microbiome results will be compared to what the colonoscopy finds.
This trial tests a new tool that looks at gut bacteria to help find colorectal cancer earlier. It's for people who already had a positive result on a standard stool test (FIT) as part of a national screening program.
This trial tests a new stool-based test (FIT) to see if it can help find colon cancer early in people with Lynch syndrome. You will collect stool samples at home and complete surveys before your regular colonoscopy.
This trial tests a new stool-based screening test that may find colorectal cancer and advanced adenomas (precancerous growths) early. It studies whether the test works well compared with the standard colonoscopy, so it could offer an easier, less invasive screening option in the future.
This study tests a stool sample test to see if it can find colorectal cancer or early warning signs (precancerous growths) as well as a colonoscopy does. You will provide a stool sample before your colonoscopy, and the results will be compared.
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
