[Errors in the clinical staging of prostatic cancer].

The relationship between the clinical and pathological stages of clinically localized prostate cancer (PCa) was analyzed in 68 patients. All of then underwent ilio-obstructive lymphadenectomy and node affectation was found in 16 patients (23%). Out of 64 patients undergoing radical prostatectomy, 23 (36%) presented invasion of prostate capsule and/or seminal vesicle infiltration. Of the total 68 patients, 28 (41%) showed local dissemination and/or nodular affectation. A direct correlation was seen between clinical stage and both incidence of local dissemination and nodular affectation. Pre-operative PSA and tumoral grade were correlated to the pathological stage.
