AB - Two hundred and three male patients underwent transrectal ultrasonography(TRUS) examination because of palpable nodule or hard consistency of theprostate. Of these, 56 of 65 (86.2%) digital rectal examination (DRE)-abnormaland 34 of 138 (24.6%) DRE-normal patients received transrectal sonoguidedcore needle biopsy. Among the DRE-abnormal patients, 18 (32.1%)had prostatic adenocarcinoma by biopsy with 2 additional patients who hadinitial negative biopsies eventually found to have cancer by transurethralresection of the prostate. In contrast, only 2 (5.9%) of 34 DRE-normal patientshad cancers that were both hypoechoic and peripheral zone located. In 13patients with transitional zone located lesions (hypoechoic 9, isoechoic 4),none had cancer. Of 27 patients who had normal DRE and unsuspectedTRUS and received transurethral prostatectomy because of bladder outletobstruction, 4 (14.8%) had cancer. In this study, hypoechoic lesions werefound in 68 patients, among them 60 (88.2%) underwent biopsy but only 14(23.3%) had cancer. From the results of this study, we concluded that TRUScan be a useful adjunct of DRE in detecting prostatic malignancy, especiallywhen there has been an abnormal DRE, but its role on a digitally normalprostate requires further evaluation. Serum prostate-specific antigen can be anadditional indicator to increase the prostate cancer detection rate.
