What this trial studies

This pilot study is a single center, randomized controlled trial involving 24 participants diagnosed with brain metastases. It compares the effects of a ketogenic diet against an alternative diet over a 16-week intervention period. Participants will receive education, recipes, and food supplies to support their assigned diet, while their quality of life will be monitored through psychosocial and behavioral inventories. The study aims to explore how a ketogenic diet may enhance the effectiveness of surgery and radiation therapy in treating brain metastases.

Who should consider this trial

Good fit: Ideal candidates are adults with measurable brain lesions, a BMI of 18 kg/m2 or higher, and an ECOG performance status of 0-1.

Not a fit: Patients undergoing whole brain radiation therapy or with certain medical conditions such as type 1 diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel dietary approach to improve treatment outcomes for patients with brain metastases.

How similar studies have performed: While there have been preclinical studies suggesting benefits of ketogenic diets in enhancing cancer treatment, this specific approach in brain metastases is novel and has not been extensively tested in clinical settings.
