Cholesterol-lowering Statins May Make Radiation More Effective at Treating Prostate Cancer

The study also demonstrated that men who took statins during high-dose radiation therapy had a lower rate of the cancer spreading to distant parts of the body.

"We were, indeed, surprised by the findings that statins used by these patients for other conditions was shown to improve the effectiveness of radiation treatment in killing prostate cancer cells,” said Michael J. Zelefsky, M.D., the senior author of the study and a radiation oncologist at Memorial Sloan-Kettering Cancer Center (New York, NY, USA). "The use of statins during radiation may also be effective in the treatment of other types of cancer. However, more studies are necessary to explore the association between statins and radiation treatment in curing cancers.”

The retrospective study involved nearly 900 men treated with high-dose radiation therapy for prostate cancer, some of whom were also taking statin drugs, from January 1995 to July 2000. Statins are a class of drugs used to lower the cholesterol level in individuals with or at risk of cardiovascular disease.

The study was presented at a scientific session October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th annual meeting held in Los Angeles, CA, USA.
