Helping the immune system attack colorectal cancer by changing the tumor environment

Targeting the Immunosuppressive Tumor Microenvironment for Colorectal Cancer Treatment

NIH-funded research University of Kentucky · NIH-11173897

This project tests whether boosting ketone levels with a ketogenic diet or the ketone body β-hydroxybutyrate can help immunotherapy work better for people with colorectal cancer that currently does not respond to immune treatments.

What this research studies

Researchers are looking at how lowering cancer cells' suppression of the immune system might let immunotherapy work for more people with colorectal cancer. They will study whether a ketogenic diet or giving the ketone β-hydroxybutyrate changes cells in the tumor environment that block immune attacks. Much of the work uses laboratory and mouse models to understand how these changes affect immune cells and cancer-associated fibroblasts. The team hopes these findings could point to new ways to combine diet or ketone treatments with immune checkpoint drugs for patients.

Who could benefit from this research

Good fit: Ideal candidates would be people with metastatic colorectal cancer, especially those with microsatellite-stable tumors that do not respond to current immune checkpoint therapies.

Not a fit: Patients whose tumors already respond to immunotherapy (for example MSI-high tumors), patients with other cancer types, or people unable to follow a ketogenic diet may not directly benefit from this project.

Why it matters

Potential benefit: If successful, this approach could make immunotherapy effective for many patients with microsatellite-stable metastatic colorectal cancer who currently have few options.

How similar studies have performed: Preclinical studies, including work from this team in mouse models, have shown that ketogenic approaches and β-hydroxybutyrate can boost the effect of immunotherapy, but this strategy remains largely untested in people.
