What this trial studies

This study evaluates how a Modified Mediterranean Diet affects the intestinal microbiota in patients with metastatic colorectal cancer undergoing chemotherapy. Participants will be randomized into two groups: one following the modified diet and the other maintaining their usual diet. The study will assess nutritional status, collect biological samples, and monitor clinical progress over several visits. The goal is to understand the relationship between diet, microbiome diversity, and patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a diagnosis of metastatic colorectal cancer who are undergoing first-line chemotherapy.

Not a fit: Patients with a MUST score greater than 2 or those requiring parenteral or enteral nutrition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the quality of life and treatment outcomes for colorectal cancer patients through dietary modifications.

How similar studies have performed: Other studies have shown promising results with dietary interventions in cancer treatment, suggesting potential benefits, though this specific approach is relatively novel.
