Dietary changes to reduce heart damage in breast cancer patients

Protein and Calorie Restriction as Treatment for Prevention of Cardiotoxicity in Women Receiving Chemotherapy.

Not applicable Interventional Erasmus Medical Center · NCT06622954

This study is testing if a special diet that cuts calories and boosts protein can help protect the hearts of women with early-stage triple-negative breast cancer during chemotherapy.

What this trial studies

This clinical trial aims to evaluate the effects of a short-term diet that restricts calories and increases protein intake on cardiotoxicity in women with early-stage breast cancer undergoing anthracycline chemotherapy. Participants will be divided into two groups: one receiving the dietary intervention and the other following a regular diet. The primary outcome will be measured by the levels of high-sensitivity troponin T (hsTnT) to assess heart damage. The study focuses on newly diagnosed triple-negative breast cancer patients aged 18 to 75.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 75 with newly diagnosed triple-negative breast cancer who are about to start anthracycline-based chemotherapy.

Not a fit: Patients with a known history of cardiac dysfunction or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce heart damage in breast cancer patients undergoing chemotherapy.

How similar studies have performed: While dietary interventions in cancer treatment are being explored, this specific approach to prevent cardiotoxicity is relatively novel and has not been extensively tested in prior studies.
