| الوصف: | We determine the incidence of biopsy detectable prostate cancer in men with clinical benign prostatic hyperplasia (BPH) and prostate specific antigen (PSA) elevation who are candidates for open prostatectomy, and the histology of prostatic tissue of men who underwent surgery.Sextant peripheral zone prostate biopsies were performed in 128 consecutive men with obstructive voiding symptoms who had digital rectal examination not suspicious for cancer, PSA greater than 4.0 ng./ml. and prostate volume 75 ml. or greater. Of the patients 59 also underwent transition zone biopsy. Median PSA was 9.9 ng./ml. (range 4.1 to 80.0), median prostate volume was 92 ml. (range 75 to 220), median PSA density was 0.10 ng./ml./ml. (range 0.03 to 0.80) and median percent free PSA in 43 patients was 23.6 (range 8.8 to 41.3).Of the 128 patients 16 (13%) had malignant biopsy including 1 who had cancer detected with transition zone biopsy only. Gleason score of tumors ranged from 4 to 8 (median 5). Of 57 patients who underwent prostatectomy 6 (11%) had stage T1a and 2 (4%) had stage T1b cancer. Among men without an indwelling urethral catheter due to acute urinary retention mean PSA, PSA density and percent free PSA were not significantly different in those with benign and malignant biopsies and/or prostatectomy specimens.Greater than 10% of men with PSA elevation who are potential candidates for open prostatectomy will have biopsy detectable prostate cancer. This diagnostic yield, while lower than that reported for unselect men with normal digital rectal examination and PSA elevation, may justify preoperative peripheral zone biopsy to avoid surgical misadventure during open enucleation. Among patients with benign peripheral zone biopsy there is a less than 5% prevalence of large volume tumors that may complicate open enucleation. |
