MONTESINO SEMPER, M. et al. Minimal prostatic adenocarcinomas in the biopsy treated with radical prostatectomy. Actas Urol Esp [online]. 2005, vol.29, n.5, pp.481-484. ISSN 0210-4806.

Fundamentals: Valuation about clinical pathologyc facts of patients having undergone a radical prostatectomy due to a minimal prostate adenocarcinoma shown at the biopsy. Methods: Retrospective analysis of patients having undergone a radical prostatectomy due to a minimal prostate adenocarcinoma shown at the biopsy in front of the remaining radical prostatectomies. Results: In 20 patients (7,6%) out of the 260 having undergone a radical prostatectomy between 1992 and 2004 the biopsy was informed as "minimal adenocarcinoma". These patients ranged 58 to 73 years with PSA levels from 5.2 to 17.1 ng./ml. Everyone except one were clinically T1c. At the definitive pathological study the Gleason was 6, 4, 3 and 2 in 3, 3, 8 and 4 patients respectively, with one having a minimal adenocarcinoma not graded and another one with a PIN ?. 3 showed only 1 focus with a tumoral volume less than 5% of the tissue (84.2% with significant tumor or multifocal). The final staging was 1 pT0 (PIN ?), 7 pT2a, 11 pT2b and 1 pT3a (62.5% bilaterals). Relating to the remaining patients under prostatectomy, patients with minimal adenocarcinoma presented significative differences in Gleason sum (p < 0.029) and staging (p = 0.02); no in PSA mean (p =0,243). Summary: Minimal adenocarcinomas of the prostate at the biopsy are significant but do present lower staging and grading in relation with the rest of patients.
