The significance and clinical utility of the detection of primary malignant circulating prostate cells: a review of the evidence

Abstract

Primary malignant circulating prostate cells (CPCs) are those detected in blood before definitive treatment for prostate cancer. CPCs can be detected in men with benign prostate disease; however, some methods to distinguish between benign and malignant prostate cells have to be validated. This study presents a review of the subject, including theoretical considerations for the selection of markers to detect them, the different methods used, and the utility of their detection in identifying men with prostate cancer and as a prognostic factor.
