The screening programs for prostate cancer will affect a number increasing of patients over 50 years with consequence rising the bioptic demand. Nevertheless the istopathologic results are negatives for carcinoma in the most part of patients. It's evident that a part of carcinomas are lost at biopsy. Two hundred four patients where submitted at second bioptic session after a maximum of 12 months. Our results show a percent probability of positive findings in 12%. In 75% cancer diagnosed in that second session had clinically significance. Prostate specific antigen (PSA) value, in our study, is the most positive predictive parameter for prostate cancer at second biopsy. Patients with PSA > 10 ng/ml have a risk 7 times greater of having a prostatic cancer respect to patients with PSA <10 ng/ml. PSA density, PSA velocity and the presence of ipoecoic areas previously biopsied, aren't risk factors for detection of prostate cancer at second bioptic session.
