Dietary Interventions Enhance Immunotherapy in Prostate Cancer

Research from the University of Notre Dame highlights the importance of dietary interventions in enhancing immunotherapy responses in prostate cancer. Investigators found that certain diets, such as the ketogenic diet, and bioactive compounds like white button mushroom extract, can modulate the tumor microenvironment and improve immunotherapy efficacy. Additionally, specific diet-derived factors have demonstrated anti-tumor immune effects, representing new avenues for combination therapy.

Key Takeaways:

• Prostate cancer is a leading cause of cancer-related mortality in men, with a poor survival rate and limited effective therapies.
• Emerging evidence suggests that dietary interventions can modulate the tumor microenvironment and enhance immunotherapy responses in preclinical and early clinical studies.
• The ketogenic diet, methionine restriction, and bioactive compounds like white button mushroom extract have been shown to modulate the tumor microenvironment and enhance immunotherapy efficacy.
• Specific diet-derived factors, such as beta-hydroxybutyrate, have demonstrated anti-tumor immune effects, representing new avenues for combination therapy.
• Immunotherapy has achieved significant success in other malignancies, but prostate cancer's immunosuppressive tumor microenvironment blunts immunotherapy efficacy.
• Integration of dietary interventions with immunotherapy may offer a streamlined perspective to augment treatment efficacy.
• Financial supporters for this research include the Interdisciplinary Interface Training Program at the University of Notre Dame, the Boler Family Foundation, the National Institutes of Health (NIH) - USA, and the United States Department of Defense.
