Introduction
The Prostate Cancer Prevention Trial, or PCPT, is a study designed to see whether the drug finasteride (trade name Proscar) can prevent prostate cancer in men ages 55 and older. (See a summary of the protocol.)
In June 2003, the PCPT was stopped early because of a clear finding that finasteride reduced the incidence of prostate cancer. However, those trial participants who did develop prostate cancer while taking finasteride experienced a slightly higher incidence of high-grade tumors. Researchers are continuing to analyze the data to find out whether finasteride actually caused high-grade tumors.
The links on the left of this page will take you to more detailed information about the trial and its results so far.
Prostate cancer is a critical public health problem: more than 220,000 men will be diagnosed with prostate cancer in the United States this year and almost 29,000 will die of the disease.
