Personalized nutrition intervention for breast cancer patients

A Phase 2 Single-blinded Randomized Study of Algorithm-based Personalized Nutrition Intervention Compared to Standard Diet Intervention in Patients Treated With Endocrine Therapy for Early Stage, Hormone Receptor Positive Breast Cancer

NA · Sheba Medical Center · NCT04079270

This study is testing if a personalized diet based on gut health can help women with hormone receptor-positive breast cancer manage weight gain and improve their overall health while they are on treatment.

What this trial studies

The Breast Cancer Personalized Nutrition study evaluates how a microbiome-based personalized diet can help manage weight gain and improve health outcomes in hormone receptor-positive breast cancer patients undergoing adjuvant endocrine treatment. The study recognizes that weight gain is a common issue for breast cancer survivors, particularly those on endocrine therapy, and aims to tailor dietary interventions based on individual microbiome analysis. By analyzing stool samples and using algorithms to predict glycemic responses, the study seeks to create personalized dietary plans that may enhance treatment adherence and reduce recurrence risk.

Who should consider this trial

Good fit: Ideal candidates are hormone receptor-positive breast cancer patients who have completed surgery and are currently receiving adjuvant endocrine therapy.

Not a fit: Patients who are currently on oral antibiotics or antifungals may not benefit from this study due to potential interference with microbiome analysis.

Why it matters

Potential benefit: If successful, this study could provide a personalized dietary approach that helps breast cancer patients manage weight gain and improve their overall health during treatment.

How similar studies have performed: Other studies have shown promising results with personalized nutrition approaches, particularly in managing metabolic responses in cancer patients, suggesting this study builds on established concepts.
