Abstract

To determine the effect of prostatitis on serum prostate specific antigen in the diagnosis of prostate cancer in Middle Eastern men, H&E-stained sections of all consecutive prostate specimens were reviewed for diagnosis (malignant or benign) and pattern of inflammation. Inflammation was categorized into acute, active chronic and chronic inactive and graded semi-quantitatively according to previously published criteria. Results were correlated with serum PSA obtained from patients' records. Of 513 prostate specimens reviewed; 435 (84.8%) were benign and 78 (15.2%) were malignant. Chronic inactive prostatitis was present in 259 (204 benign, 55 malignant) and active chronic prostatitis in 221 (204 benign, 17 malignant). Acute prostatitis alone was not observed and prostatitis was absent in 33 (27 benign, 6 malignant). There was no significant difference in the prevalence of inactive chronic prostatitis between benign and malignant specimens (p < 0.071), but active chronic prostatitis was more prevalent in benign specimens (p < 0.001). Increasing serum PSA was observed for increasing grades of both inactive and active chronic prostatitis in both benign and malignant disease. Prostate cancer showed higher serum PSA levels than benign, at different cut-off points (4 ng/ml = p < 0.0001; 8 ng/ml = p < 0.0001; 12 ng/ml = p < 0.0001). However, significant numbers of patients with benign prostate biopsies presented with PSA above 12 ng/ml (82/260 = 32%). We conclude that active chronic prostatitis is common in Middle Eastern men with benign prostatic disease and a significant number of these present with very high PSA levels, some over 300 ng/ml.
