  • Studies Make Case for Finasteride to Prevent Prostate Cancer
    Three new analyses of data from a large prostate cancer prevention trial bolster the case for finasteride as a preventive agent against prostate cancer, according to an article published online May 18, 2008, by the journal Cancer Prevention Research.
  • Finasteride Not Linked to High-Grade Prostate Cancers
    According to two studies in the September 11, 2007, issue of the Journal of the National Cancer Institute, finasteride is unlikely to induce high-grade prostate cancers in men who take the drug to prevent the disease.
  • Prostate Cancer Risk Calculator Available Online
    Researchers have developed an online statistical tool for estimating an individual's risk of developing prostate cancer. The risk calculator is designed to help certain men and their physicians evaluate the potential risks and benefits of being screened for prostate cancer.
  • Prostate Cancer PSA Testing Limitations Demonstrated
    A large-scale study of prostate-specific antigen (PSA) screening for prostate cancer concluded that, contrary to current clinical practice, there is no definitive "cutpoint" PSA level to determine the level of risk for the disease, according to the July 6, 2005, issue of the Journal of the American Medical Association.
  • NCI Communicates Information on First Prostate Cancer Prevention Trial
    An article in the July-August, 2004, issue of Urologic Oncology describes the communication techniques used by NCI to deliver information to the public about the results of the Prostate Cancer Prevention Trial (PCPT).
  • No "Magic Threshold" for PSA Screening, Study Finds
    Data from the National Cancer Institute's (NCI) Prostate Cancer Prevention Trial (PCPT) published recently showed that a substantial number of men enrolled in the trial as controls were found to have prostate cancer despite consistently normal screening tests over the study period. The study results were published in the May 27, 2004, New England Journal of Medicine.
