Screening for prostatic carcinoma with prostate specific antigen.
The usefulness of prostate specific antigen (PSA) in screening for prostatic carcinoma was studied in 262 inpatients of the department of internal medicine. All patients underwent a rectal digital examination and determination of PSA by the Tandem-E method (Hybritech). The plan was to perform biopsies if there were suspicious findings on the rectal examination or if the PSA value was more than 10 ng/ml. The PSA values were < or = 4 ng/ml in 219 patients (83.6%), > 4 to 10 ng/ml in 27 patients (10.3%) and > 10 ng/ml in 16 men (6.1%). In consideration of the severity of disease which limited life expectancy we did not perform a biopsy on 37.5% of the patients with PSA > 10 ng/ml. 7 patients with prostatic carcinoma were found. Their PSA values varied between 11.2 and 875 ng/ml. The cancer detection rate was highest for the combination of a suspicious rectal examination and a PSA value > 10 ng/ml (70%).
