[Contribution of pathological anatomy before and after total prostatectomy]

Before radical prostatectomy, the pathologist analyzes the prostate biopsies. He has to affirm the diagnosis of cancer when present, and to provide prognosis parameters such as the Gleason score, the percentage of tumor, and to report an extraprostatic extension when present. After the radical prostatectomy, the pathologist has to analyze the surgical specimen. Two main features have to be reported including the tumor stage and the Gleason score.
