Advantage of systematic random ultrasound-guided biopsies, measurement of serum prostate-specific antigen level and determination of prostate volume in the early diagnosis of prostate cancer.
Two hundred and sixteen patients, presenting with a suspicious digital examination (stage T3 excluded) or a level of prostate-specific antigen (PSA) greater than or equal to 2.5 ng/ml, assessed by radioimmunoassay, underwent a transrectal ultrasound examination. Prostate volume was systematically calculated and correlated to PSA level. Biopsies were performed: (1) on suspicious peripheral hypoechoic areas; ultrasound-guided biopsies; (2) systematically on the 2 prostate lobes, whatever the result of transrectal ultrasound imaging:random systematic ultrasound-guided biopsies. In the 186 patients who had never undergone prostate surgery, ultrasound-guided biopsies showed 42 prostate cancers and random systematic ultrasound-guided biopsies showed 75; 14 of the 76 patients with normal digital rectal examination and transrectal ultrasound imaging had a prostate cancer. In the 30 patients who had previously undergone surgery for benign prostatic hypertrophy, random systematic ultrasound-guided biopsies showed 18 prostate cancers, 13% more than ultrasound-guided biopsies; 75% of patients with a serum PSA greater than 5 ng/ml had a prostate cancer. A very significant correlation was found between PSA level and prostatic volume (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
