Integrated predictive model for prostatic cancer using clinical, laboratory and ultrasound data.

Objective: to develop a predictive model to estimate the probability of prostate cancer prior to biopsy.

Methods: from September 2009 to January 2014, 445 men underwent prostate biopsy in a radiology service. We excluded from the study patients with diseases that could compromise the data analysis, who had undergone prostatic resection or used 5-alpha-reductase inhibitors.
