What is the pathologist saying? Interpretation of the prostate pathology report

Abstract

Management of patients presenting with elevated serum prostate-specific antigen levels, or those with previously diagnosed prostate carcinoma, is very much dependent on the pathology report on needle biopsy or radical prostatectomy specimens obtained from these patients. In contrast to a diagnosis of benignity or high-grade prostatic intraepithelial neoplasia, a diagnosis of atypia on needle core biopsy is usually an indication for a repeat biopsy; however, it is important to understand that atypia and other related terms are not specific diagnoses. The pathology report on different prostate specimens with a diagnosis of carcinoma usually includes the Gleason grade and extent of carcinoma among other morphological prognostic and predictive factors. Understanding the significance of these morphological factors and how they are evaluated and incorporated into the pathology report, as well as newer developments in this field, can assist urologists in the interpretation of the pathological findings and ultimately lead to better clinical care.
