Prostate cancer detection in a clinical urological practice by ultrasonography, digital rectal examination and prostate specific antigen.

The prostate cancer detection rate from screening by digital rectal examination and tactilely guided prostate biopsy is approximately 1.7%. Among 1,807 men a detection rate of 14.6% was achieved in a clinical urological practice by physician-conducted prostate ultrasonography, digital rectal examination and determination of serum prostate specific antigen. Results are presented in 5-year increments as well as for the group as a whole. The possible benefit to be derived from an improved detection rate is undetermined. Recommendations are made regarding the clinical use of these diagnostic modalities.
