Fasting and its Therapeutic Impact in Brain Tumors

Abstract

Recent Findings

Each year 40,000 people are diagnosed with primary brain tumors. Malignant gliomas account for more than 50% of them and are universally fatal despite aggressive surgery and combined chemoradiotherapy. Identification of novel therapeutic targets has been challenging. New areas of interest are now focusing on exploiting special metabolic adaptations these tumors have developed in response to the stress caused by their rapid growth rate, exceeding their vascular supply.

Purpose of Review

This article is an attempt to review a controversial strategy of modulating tumor biology by understanding their metabolic characteristics, how they differ from normal healthy cells, and implementing therapies that include nutritional interventions.

Summary

Although fasting as part of the management of brain malignancies is controversial and may be contrary to popular opinion, developing supportive evidence in targeting their special metabolic profile is promising and fascinating.

This comment explains how chemotherapy-induced oxidative stress shrinks the tumor volume and also negatively impacts normal cells; however, if you induce short-term fasting before or after chemotherapy, the fasting state results in a protective differential stress resistance in normal cells that is not seen in cancer cells.
