ABSTRACT
OBJECTIVES: To evaluate PCa incidence in patients with one or more negative extended prostate biopsy who underwent repeat biopsy or TURP. MATERIAL AND METHODS: From June 2003 to February 2008, 308 patients were submitted to repeat prostate biopsy (median 20.5 cores) and 120 patients underwent TURP after one or more 12 cores prostate biopsy. Indications for biopsy were: abnormal DRE; PSA > 10 ng/mL; PSA included between 4.1-10 or 2.6-4 ng/mL with free/total PSA < or = 25% and < or = 20%, respectively 262 and 46 underwent a second and a third biopsy: 218 because for high levels of PSA, 40 and 50 patients for a previous diagnosis of HGPIN and ASAP, 28 had an abnormal DRE. PSA in patients who underwent TURP was 11.6 ng/mL (median); in all cases DRE was negative and only 76 patients referred LUTS. RESULTS: PCa incidence at repeat biopsy was 16.9%; 96.2% of cancers were diagnosed at a second biopsy and 3.8% at a third one. PCa incidence was higher in patients with previous ASAP (43.4% and 50%) vs patients with HGPIN (25% and 0%) or benign pathology (11.9% and 0%). PCa was diagnosed in 11.1% and 19% of patients who underwent TURP previously submitted to a first and a second biopsy, respectively. CONCLUSIONS: In case of persistent suspicion of PCa after a repeated negative saturation biopsy, TURP should be proposed as part of the diagnostic procedure aside from LUTS, especially in patients with a life expectancy greater than 10 years.
