Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 45-84 with suspected advanced adenomas or newly diagnosed colorectal cancer scheduled for surgery, as well as those at average risk undergoing routine colonoscopy.

Probably not a fit

Patients with a current diagnosis of cancer or those who have had a curative biopsy during colonoscopy will 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 collect blood samples and clinical data from participants suspected of having advanced adenomas or newly diagnosed with colorectal cancer. It will also include individuals at average risk undergoing routine colonoscopy. The goal is to optimize a circulating free DNA (cfDNA) marker panel for better detection of colorectal cancer and advanced adenomas. Participants will provide up to 40 ml of blood during the study visit after giving informed consent.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection of colorectal cancer and advanced adenomas, potentially saving lives.

How similar studies have gone: Other studies have shown promise in using cfDNA markers for cancer detection, indicating that this approach has potential based on previous findings.
