Comparison of Digital Rectal Examination and Prostate Specific Antigen in Early Detection of Prostate Cancer
This study compares the value of digital rectal examination (DRE) and prostate specific antigen (PSA) determination in the detection of prostate cancer. 1, 000 men aged>50 from the Osijek surroundings were examined. The subjects with prostatitis were excluded from the study. The subjects with elevated concentration of total prostate specific antigen and/or digital rectal examination suspect of carcinoma uderwent prostate biopsy. The rate of prostate cancer detection showed to be 3.3% for PSA>4 ng/ml, 2% for abnormal finding of DRE, and 3.7% for combination of the two methods. Out of 35 patients with prostate cancer detected, 19 had suspect DRE finding and 32 had PSA exceeding 4 ng/ml. Thus, PSA pointed to the diagnosis of prostate cancer in 91.4%, and abnormal finding of DRE in 54.2% of cases, the difference being statistically signicant. The positive predictive value was 48.7% for abnormal finding DRE, 47% for PSA>4ng/ml, and 80.0% for the combination of both. Although PSA determination detected a considerbale proportion of tumoris missed on DRE, the former alone was found to be insufficient as a screening method because of its inadequate sensitivity. When combined wtih digital rectal examination, the probability of prostate cancer detection increased considerably.
