NCT06794931

Brief Summary

The study plans to evaluate the impact of the Modified Mediterranean Diet on the biodiversity of the intestinal microbiota (the set of physiological bacteria present at the intestinal level) in patients suffering from metastatic colorectal cancer undergoing chemotherapy treatment +/- biological agent, comparing the microbiota with that of patients following a Western or standard diet. Specifically, as well demonstrated in clinical studies, there are populations of bacteria that play a role in protecting the intestinal barrier and whose proliferation could be promoted by the Modified Mediterranean Diet. The study also intends to evaluate the influence of the microbiome on the clinical progress of the disease in terms of side effects and quality of life.

Outcome Measures

Primary Outcomes (1)

  • Evaluate the impact of the modified Mediterranean diet (DMM, Arm A) compared to a standard Western diet (DSO, Arm B) on microbiota

    Comparison of the Firmicutes/Bacteroidetes ratio after 45 days (V2) of first-line chemotherapy +/- biological agent (anti-Epidermal Growth Factor Receptor (EGFR), anti-VEGF) in patients on a modified Mediterranean diet (DMM) compared to patients on a standard Western diet (DSO)

    V2 (45 days after V1)

Secondary Outcomes (5)

  • Comparison of the percentage of patients with gastrointestinal effects

    V2 (45 days after V1)

  • Comparison of the percentage of patients with severe gastrointestinal effects

    V2 (45 days after V1)

  • Variation of the change in the Firmicutes/Bacteroidetes ratio

    Baseline (V1), after 45 day from baseline (V2), after 90 days from baseline (V3)

  • Variation of the overall composition of the microbiome

    Baseline (V1), after 45 day from baseline (V2), after 90 days from baseline (V3)

  • Variation of the microbiome and metabolome

    Baseline (V1), after 45 day from baseline (V2), after 90 days from baseline (V3)

Study Arms (2)

modified Mediterranean diet (DMM)

EXPERIMENTAL

It consists of a food plan in favor of bacterial biodiversity which focuses above all on foods containing high quality prebiotic fibres, instead reducing the total quantity of fibers compared to the indications provided by the Reference Intake Levels of Nutrients and Energy (LARN) for the Italian population, in consideration of the gastrointestinal side effects of chemotherapy.

Other: NutritionOther: Biological samples collection

standard western diet (DSO)

OTHER

The Western Diet or standard diet represents the diet most commonly used by the population in many developed countries; it reflects participants' daily eating habits, ensuring that the control group accurately represents typical eating behavior.

Other: Biological samples collection

Interventions

The patient will be instructed to follow the modified Mediterranean diet or his usual diet based on the assigned treatment group.

Also known as: Specific diet
modified Mediterranean diet (DMM)

Additional biological samples will also be collected.
