What this trial studies

This study aims to determine if lifestyle modifications, including diet and exercise, combined with daily aspirin and vitamin D, can reduce the risk of colorectal cancer recurrence in patients with minimal residual disease. The primary objective is to estimate the clearance rate of circulating tumor DNA (ctDNA) after three months of these interventions. Secondary objectives include evaluating ctDNA dynamics and estimating the recurrence rate at one year for participants who complete the intervention. The study involves behavioral support counseling sessions to assist participants in making these lifestyle changes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with high-risk stage II, III, or IV colorectal adenocarcinoma who have no evidence of disease after local therapy and detectable ctDNA mutations.

Not a fit: Patients with concurrent malignancies, active gastrointestinal bleeding, or those unable to safely participate in physical activity may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly lower the chances of colorectal cancer returning in patients with minimal residual disease.

How similar studies have performed: Other studies have shown promising results with lifestyle interventions in cancer care, suggesting potential for success in this approach.
