Purpose: The term atypical small acinar proliferation (ASAP) has been proposed by pathologists to indicate foci of small atypical acini found in prostatic biopsies that have some but not all of the features of adenocarcinoma. We determined the incidence of ASAP at our institution and evaluated the role of immediate radical prostatectomy (RP) in these patients.
Materials And Methods: From January 2001 to December 2002, 1,327 patients underwent systematic transrectal prostate biopsies because of increased prostate specific antigen (PSA).
