[Prognosis and predictive factors of prostate cancer in the prostatic biopsy].

This paper reviews the morphological cancer diagnosis criteria on needle biopsies, the predictive meaning of the pathological lesions of HGPIN, HAA, and P.I.A and the peculiar histopathological patterns in prostatic adenocarcinoma. We present the histological parameters that the pathologist has to informe in the diagnositic, on the routine prostate needle biopsy: Gleason histological degree, histological type, number of invaded cilindres, percentage of tumor in each cylinder, location of the biopsy and ymphovascular invasion. We also emphasize the importance of new predictive biomarkers nowadays in study and probably involved in tumor progression.
