Predictive value of prostate specific antigen density in the detection of prostate cancer in patients with elevated prostate specific antigen levels and normal digital rectal findings or stage A prostate cancer

We compared the usefulness of PSA and PSA density (PSAD) in diagnosing prostate cancer in 102 men who had a PSA value higher than 4.0 ng/ml and normal digital rectal examination and who had undergone transrectal ultrasonography-guided systematic sextant biopsies of the prostate between August 1996 a...

Zusammenfassung:We compared the usefulness of PSA and PSA density (PSAD) in diagnosing prostate cancer in 102 men who had a PSA value higher than 4.0 ng/ml and normal digital rectal examination and who had undergone transrectal ultrasonography-guided systematic sextant biopsies of the prostate between August 1996 and October 1999. In addition, for a group of 53 patients who underwent retropubic simple prostatectomy, PSA, PSAD and PSA transition zone (PSA-TZ) examination results for those with stage A prostate cancer were compared with the results for those with benign prostatic hyperplasia (BPH). Of the former 102 men, 20 (19.6%) had prostate cancer. There was no significant difference in mean PSA level between patients with negative and those with positive biopsy results (mean 9.3 and 11.8, respectively, p = 0.295), but the mean PSAD of patients with positive biopsy results was significantly higher than that of those with negative results (mean 0.55 and 0.29, respectively, p = 0.0007). Of the 53 men who underwent retropubic simple prostatectomy, 10 (18.9%) were diagnosed with stage A prostate cancer. There was no significant difference in mean PSA, PSAD and PSA-TZ examination results between patients with BPH and those with stage A prostate cancer. For all 102 patients and for 71 patients with PSA levels of 4.1-10.0 ng/ml, a PSAD cutoff value of 0.1 reduced the number of biopsies 15.7% (16 of 102 cases), and 22.5% (16 of 71 cases), respectively. These results suggest that by measurement of PSAD some patients with benign disease could be spared a biopsy which would have been performed based on PSA results alone
