What this trial studies

This observational study evaluates patients with colorectal cancer (CRC) by conducting longitudinal plasma ctDNA biomarker profiling alongside their standard treatment and disease monitoring. Participants will provide blood samples during routine surveillance visits to assess the presence of circulating tumor DNA (ctDNA). The study aims to enhance understanding of CRC progression and treatment response through genomic profiling. It involves multiple centers to gather diverse data on patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with known or suspected colorectal adenocarcinoma who are undergoing or have undergone surgical resection with curative intent.

Not a fit: Patients who are not willing to provide additional blood samples or have a pathology inconsistent with colorectal adenocarcinoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and personalized treatment strategies for colorectal cancer patients.

How similar studies have performed: Other studies utilizing ctDNA profiling in cancer monitoring have shown promising results, indicating potential for success in this approach.
