Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 45-84 who are at average risk for colorectal cancer and are scheduled for a standard screening colonoscopy.

Probably not a fit

Patients who have a history of colorectal cancer or other malignancies, or those undergoing colonoscopy for symptoms related to CRC risk, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the performance of the Signal-C™ plasma circulating free-DNA test in detecting colorectal cancer and advanced precancerous lesions in individuals aged 45 and older who are considered at average risk. Participants will undergo a standard screening colonoscopy and provide a blood sample prior to the procedure. The study will follow participants for one year to gather data on the test's effectiveness. The goal is to improve early detection methods for colorectal cancer.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and non-invasive screening methods for colorectal cancer, potentially improving early detection and patient outcomes.

How similar studies have gone: Other studies evaluating similar blood-based tests for colorectal cancer detection have shown promising results, indicating potential for this approach.
