Testing stool samples for cancer detection in colorectal cancer survivors

Official title: The Utility and Feasibility of Mt-sDNA as a Surveillance Procedure in Colorectal Cancer Survivors

Run by Case Comprehensive Cancer Center · NCT04624555 · Data updated 2026-11-12

This study is testing if a new stool test can help find polyps and cancer in colorectal cancer survivors to see if it works better than regular check-ups.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals diagnosed with Stage I, II, or III adenocarcinoma of the colon or rectum who have undergone preoperative colonoscopy and bowel resection.

Probably not a fit

Patients with Stage IV colorectal cancer or those with certain conditions such as inflammatory bowel disease or polyposis syndromes may not benefit from this study.

What this trial studies

This observational study aims to evaluate the effectiveness of multitarget stool DNA (mt-sDNA) testing in detecting polyps and cancer in colorectal cancer survivors diagnosed with Stage I-III adenocarcinoma. Participants will provide stool samples for mt-sDNA testing before their scheduled colonoscopies at one and four years post-diagnosis. Following the testing, participants will complete a questionnaire regarding their satisfaction with the mt-sDNA procedure. The study seeks to compare the results of mt-sDNA testing with standard surveillance methods.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive method for early detection of colorectal cancer recurrence and polyps, improving patient outcomes.

How similar studies have gone: Other studies have shown promising results with similar stool DNA testing approaches, indicating potential for success in this area.
