Supplement, keto diet may boost immunotherapy

• About 13% of cisgender men around the world will receive a prostate cancer diagnosis in their lifetime.
• Despite improved screening and early detection methods, about one in 44 men die from prostate cancer.
• Using a mouse model of prostate cancer, researchers from the University of Notre Dame have now found adding a pre-ketone supplement to immunotherapy may make it more efficient in treating this form of cancer.

About 13% of cisgender men worldwide will receive a diagnosis of prostate cancer during their lifetime, making it the second most commonly diagnosed cancer globally.

Despite improved screening and early detection methods, more advanced stages of prostate cancer can be difficult to treat — scientists estimate about one in 44 men will die of prostate cancer.

Now, a new study from researchers at the University of Notre Dame — published in Cancer Research — has found that adding a component of the keto diet called a pre-ketone supplement may help a newer type of prostate cancer treatment called immunotherapy be more efficient in treating the cancer, via a mouse model.
