OBJECTIVES: To investigate whether coexistence of high-grade prostatic intraepithelial neoplasia (HPIN) should change our therapeutic approach to infravesical obstruction.
MATERIAL AND METHODS: Of 505 patients who underwent sextant transrectal ultrasonography (TRUS)-guided prostate biopsy, 65 (12.8%) had HPIN and 29 of them underwent prostatectomy (23 transurethral resection of prostate (TURP), 6 open) due to obstructive urinary symptoms. Patients without carcinoma were followed up with semiannual prostate-specific antigen (PSA) and digital rectal examination. After a follow-up of 24.8 +/- 11.0 months, 19 of 29 patients who accepted our call had another sextant biopsy.
RESULTS: Mean age and initial mean PSA values of 29 patients were 67.6 +/- 6.7 years and 9.26 +/- 5.91 ng/ml, respectively. The final pathological evaluation of the surgical specimens revealed 2 prostatic adenocarcinomas both in the TURP group. The remaining 27 (93.2%) patients were found to have benign prostatic hyperplasia (BPH) and their serum PSA levels declined from 9.26 +/- 5.91 to 4.59 +/- 2.0 ng/ml 3 months after prostatectomy. Of the 19 patients who had another biopsy with a mean PSA value of 4.06 +/- 4.61 ng/ml, 15 and 4 of them had BPH and HPIN respectively.
CONCLUSIONS: Our preliminary data indicate that the presence of HPIN on TRUS-guided biopsies is not a factor to delay an indicated surgical intervention for infravesical obstruction.
