Study: Ketogenic diet helps kill pancreatic cancer cells when combined with a triple-drug therapy

NewsGuard 100/100 Score

The findings of a new study suggest that a ketogenic diet -; which is low in carbohydrates and protein, but high in fat -; helps to kill pancreatic cancer cells when combined with a triple-drug therapy developed by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope.

In laboratory experiments, the ketogenic diet decreased glucose (sugar) levels in the tumor, suggesting the diet helped starve the cancer. In addition, this diet elevated ketone bodies produced by the liver, which put additional stress on the cancer cells. The study published in the journal Med.

By destabilizing the cancer cells, the ketogenic diet created a microenvironment in which the triple-drug therapy designed by TGen -; a combination of gemcitabine, nab-paclitaxel and cisplatin -; was more effective at knocking out the tumor, according to the study.

"By limiting glucose availability, the ketogenic diet may promote chemotherapy efficacy," said TGen Distinguished Professor Daniel D. Von Hoff, M.D., considered one of the nation's foremost authorities on pancreatic cancer. Dr. Von Hoff is one of the study authors and designers of the therapy.

In addition, the ketogenic diet was shown to have a favorable impact on antitumor immunity by inducing pro-inflammatory tumor gene expression, which further weakened the cancer.

Clinical trials at five locations

To test these laboratory findings, researchers initiated a clinical trial of up to 40 patients at five centers nationwide: HonorHealth in Scottsdale, USC in Los Angeles, Nuvance Health in Connecticut, Atlantic Health System in New Jersey, and South Texas Accelerated Research Therapeutics in San Antonio.

The clinical trial will test whether adding a ketogenic diet to the triple-drug therapy will increase overall survival in patients with pancreatic cancer. This clinical trial began in late 2020 and is anticipated to continue to accrue patients through June 2023.

Patients will be randomly assigned to either receive the triple-drug regimen while on a standard diet, while the other half will receive a ketogenic diet and the triple-drug therapy. The dietary aspects of the study are being carefully monitored.

Our laboratory experiments show that a ketogenic diet changes pancreatic cancer metabolism and its response to chemotherapy."

    I heard that cancer cannot thrive in a ketogenic environment.  It stands to reason that if you are eating ketogenic, which creates an environment wherein the cancer cannot thrive, then any cancer killing agent you introduce will do it's job better - does it also imply that a ketogenic diet alone might kill cancer?

      I don't know that they allow any trials where ketosis alone... or any other non-drug, natural therapy alone... is allowed to take place. It would seem they are only allowed to be acknowledged as an 'adjuvant' therapy, meaning, a treatment used AFTER they use the deadly toxic (and super expensive) therapies in their usual arsenal.
