The use of prostate-specific antigen (PSA) in the diagnosis of prostate cancer is controversial due to false-positive results caused by benign prostatic hyperplasia. Several groups have suggested the usefulness of the percentage of free PSA (%fPSA) in patients with PSA levels between 4 and 10 microg/l. Based on previously obtained results, biopsy is carried out in our hospital if the PSA is greater than 10 microg/l or if the %fPSA is lower than 20% and PSA is between 4-10 microg/l. In this study, we have compared these results with those obtained with a logistic regression model based on the determination of PSA and %fPSA. The diagnostic efficacy of the logistic regression model is greater than that of the currently used model. The posterior construction of a nomogram based on the data obtained greatly facilitates the application of the logistic regression model.
