  • The most clinically useful model for predicting histologically identifiable residual cancer was either a serum PSA value greater than 2 or a PSA value less than or equal to 2 and abnormal TRUS findings. The positive and negative predictive values of the model were 84% and 83%, respectively. The model predicted biopsy results correctly in 26 of 31 patients (84%). Transrectal ultrasonography is recommended as a diagnostic tool for patients whose PSA level ranges from a detectable level to less than or equal to 2 ng/mL.
