Cancer in the transition zone represents 20-25% of cases, its diagnosis is often incidental, being identified clinically as suspected adenomas. Objective: To determine the incidence of adenocarcinoma in the transitional Prostate Zone and identify the degree of adenocarcinoma and precancerous stages thereof. Methods: Longitudinal retrospective study from 2013-2018 in the city of Cochabamba-Bolivia; Study population: patients undergoing simple, retropubic and / or transvesical prostatectomy. Data collection: from medical records, in patients with benign prostatic hyperplasia and who have no atypia and neoplasms. Results: 76 patients were identified, of which; 5 patients resulted with adenocarcinoma and 9 patients among: High Grade Prostatic Intraepithelial Neoplasia 2.6%, small atypical acinar proliferation 7.9%, thus representing 10.5%. As for the invasion, they represented 5.3% with perineal invasion, 2.6% lymphovascular invasion and none with extravascular invasion. Discussion: Patients with transitional prostate cancer have a high specific prostate antigen susceptible to adenocarcinoma. However, this investigation found high-risk prostate adenocarcinoma with total prostate antigen total less than 4 ng / ml. Despite the clinical instruments and indications for the decision of surgical therapy of an alleged benign prostatic hyperplasia, there is a 6.5% incidence of adenocarcinoma in the Transitional Area, with a 10.5% incidence of presentation of forms of Proliferation of Atypical Small Acini and 17.1% of the patients in the study are at risk of lethality of the disease.
