Exercise may lead to faster prostate tumor growth
Date:4/13/2008

DURHAM, N.C. -- Prostate tumors grew more quickly in mice who exercised than in those who did not, leading to speculation that exercise may increase blood flow to tumors, according to a new study by researchers in the Duke Comprehensive Cancer Center (DCCC) and the Duke Prostate Center.

Our study showed that exercise led to significantly greater tumor growth than a more sedentary lifestyle did, in this mouse model, said Lee Jones, Ph.D., a researcher in the DCCC and senior investigator on this study. Our thought is that we may, in the future, be able to use this finding to design better drug delivery models to more effectively treat prostate cancer patients, and those with other types of cancer as well.

The findings were presented in a poster session at the American Association for Cancer Research annual meeting on April 13 in San Diego, Calif. The study was funded by the United States Department of Defense, the Prostate Cancer Foundation and the American Urological Association Foundation, Rising Star in Urology Award, given to Stephen Freedland, one of the studys investigators.

The researchers implanted prostate tumors subcutaneously in the flanks of 50 mice and then put half of the mice in cages with exercise wheels and half in cages with no wheels. All mice were fed the same diet. On average, the exercising mice ran more than half a mile each day.

We found that among the mice that had the opportunity to voluntarily exercise, tumors grew approximately twice as fast as they did among the mice that did not have the opportunity to exercise, Jones said.

Researchers and clinicians know that a challenge in delivering chemotherapy and radiation to tumors can be their poor blood flow, so these findings may hint at a way in which to improve blood flow to tumors, perhaps then allowing for better distribution of medicine, he said.

Were wondering, can we combine exercise with treatments such as chemotherapy, hormone
