Molecular Staging of Prostate Cancer: Dream or Reality?
February 01, 1999
The article by Drs. de la Taille, Olson, and Katz is an accurate and concise review of clinical studies for the detection of circulating prostate cancer cells using reverse transcriptase–polymerase chain reaction (RT-PCR) technology. These investigators from the Department of Urology at Columbia-Presbyterian Medical Center have as much experience as any group in the use of RT-PCR for this purpose. Initially very strong proponents of the efficacy of RT-PCR as a staging tool, they have become slightly more reserved in the current article. In this well-written review, the authors allude to a number of issues affecting RT-PCR results from prostate cancer patients that deserve further comment.
