A compound found in soybeans almost completely prevented the spread of human prostate cancer in mice, according to a study published in the March 15 issue of Cancer Research, a journal of the American Association for Cancer Research.
Researchers from Northwestern University say that the amount of the chemical, an antioxidant known as genistein, used in the experiments was no higher than what a human would eat in a soybean-rich diet.
They found that genistein decreased metastasis of prostate cancer to the lungs by 96 percent compared with mice that did not eat the compound in their chow, making the study the first to demonstrate genistein can stop prostate cancer metastasis in a living organism.
"These impressive results give us hope that genistein might show some effect in preventing the spread of prostate cancer in patients," said the study's senior investigator Raymond C. Bergan." Now we have all the pre-clinical studies we need to suggest genistein might be a very promising chemo preventive drug."
