Radical prostatectomy for high-risk clinically localized prostate cancer: a prospective single institution series

摘要

Objective: The objective of this paper is to report on the pathologic and biochemical progression-free outcomes of patients who underwent radical prostatectomy for high-risk localized prostate cancer. Methods: Data was collected prospectively from 299 patients who underwent radical prostatectomy for high-risk clinically localized prostate cancer by 2 surgeons at a single institution. High risk was defined as 1 or more of 3 adverse factors: prostate-specific antigen (PSA) >20, biopsy Gleason score 8 to 10 and clinical stage T3. PSA recurrence was defined as PSA >0.4 ng/mL or any salvage therapy. Results: Median age was 63.3 years (46.1–75.9). Median follow-up was 4.7 years (range 0.5–17.3 years). PSA at diagnosis was >20 ng/mL in 31.4%. Biopsy Gleason score was 8 to 10 in 66.9%. Clinical stage was T3 in 24.4%. 81.6% of patients had a single baseline risk factor, 15.7% had 2 risk factors and 2.7% had all 3 risk factors. Neoadjuvant therapy was administered to 184 patients (61.5%). Pathologic stage was organ-confined in 39.6%, specimen-confined in 26%, non-specimen-confined in 26.4%, and 8% had lymph node positive disease. Overall survival, cancer-specific survival and biochemical progression-free survival was 99%, 99.67% and 70.2%, respectively. Univariate analysis showed that PSA at diagnosis, percentage of cores positive and number of risk factors were predictors of PSA recurrence ( p 20 ng/mL is a significant independent predictor of PSA recurrence.
