We evaluated the survival of patients with high-risk disease following radical prostatectomy (RP) and external beam radiation therapy (RT) during the PSA era. METHODS We identified 1,238 men who underwent RP and 609 men treated with RT between 1988–2004 who had a pretreatment prostate specific antigen (PSA) ≥ 20 ng/mL, biopsy Gleason score 8–10, or clinical stage ≥ T3. The impact of treatment modality on cancer-specific (CSS) and overall survival (OS) was analyzed using Cox proportional hazard regression models controlling for patient age, Charlson comorbidity index (CCI), and clinicopathologic tumor variables. RESULTS Patients treated with RT were older (p<0.0001), had a greater pretreatment PSA (p=0.02), higher biopsy Gleason score (p<0.0001), and more advanced clinical stage (p<0.0001). In total, 344 (57%) men who underwent RT were treated with adjuvant androgen deprivation therapy (ADT), while 418 (34%) men who underwent RP received adjuvant ADT and 136 (11%) received adjuvant RT. Median follow-up was 10.2, 6.0, and 7.2 years after RP, RT + ADT, and RT alone. Estimated 10-year CSS following RP and RT + ADT was equivalent (92%), and was modestly better than RT alone (88%; p=0.06). 10-year OS was significantly improved after RP (77%) versus RT + ADT (67%) or RT alone (52%; p<0.001). On multivariate analysis (Table), patients who underwent RT alone had a significantly increased risk of death from prostate cancer (p=0.0006) and overall mortality (p<0.0001) compared to patients treated with RP. No significant difference in the risk of cancer death was seen between RT + ADT and RP (p=0.90); however, men who received RT + ADT had a greater than 50% increased risk of overall mortality versus men who underwent RP (p=0.0005).

As surgery provides pathologic staging to guide the selected use of secondary therapies, prospective studies evaluating the differing impact of treatments on quality of life and non-cancer mortality are necessary to determine the optimal management approach to these men. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e355 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Stephen Boorjian Rochester, MN More articles by this author R.
