Brief Summary:
The purpose of this study is to evaluate the tolerance of one year of ketogenic diet associated with vitamin supplementation in patients treated for a metastatic renal cell carcinoma.

Condition or disease Intervention/treatment Phase
Metastatic Renal Cancer Dietary Supplement: Ketogenic diet Not Applicable

Detailed Description:

This research study is a pilot study evaluating the tolerance of a ketogenic diet associated with a standard of care in patient with metastatic renal cell carcinoma.


Cancer cells are known to have an increased glycolytic activity that allows them to product energy from anaerobic degradation of glucose. A ketogenic diet places the body in ketosis state. It forces the body to burn fat instead of glucose. Fat metabolism occurs via the mitochondrial oxidative phosphorylation. By reducing sugar intake and regulating energy metabolism, the ketogenic diet could contribute to limit tumor progression.

This diet will be introduced during one year, patient will be monitored closely with biological tests and radiological assessments every three month.
