Long-Term Survival After Radical Prostatectomy Versus External-Beam Radiotherapy for Patients With High-Risk Prostate Cancer CANCER Boorjian, S. A., Karnes, R. J., Viterbo, R., Rangel, L. J., Bergstralh, E. J., Horwitz, E. M., Blute, M. L., Buyyounouski, M. K. 2011; 117 (13): 2883-2891


The long-term survival of patients with high-risk prostate cancer was compared after radical prostatectomy (RRP) and after external beam radiation therapy (EBRT) with or without adjuvant androgen-deprivation therapy (ADT).In total, 1238 patients underwent RRP, and 609 patients received with EBRT (344 received EBRT plus ADT, and 265 received EBRT alone) between 1988 and 2004 who had a pretreatment prostate-specific antigen (PSA) level = 20 ng/mL, a biopsy Gleason score between 8 and 10, or clinical tumor classification = T3. The median follow-up was 10.2 years, 6.0 years, and 7.2 years after RRP, EBRT plus ADT, and EBRT alone, respectively. The impact of treatment modality on systemic progression, cancer-specific survival, and overall survival was evaluated using multivariate Cox proportional hazard regression analysis and a competing risk-regression model.The 10-year cancer-specific survival rate was 92%, 92%, and 88% after RRP, EBRT plus ADT, and EBRT alone, respectively (P = .06). After adjustment for case mix, no significant differences in the risks of systemic progression (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.51-1.18; P = .23) or prostate cancer death (HR, 1.14; 95% CI, 0.68-1.91; P = .61) were observed between patients who received EBRT plus ADT and patients who underwent RRP. The risk of all-cause mortality, however, was greater after EBRT plus ADT than after RRP (HR, 1.60; 95% CI, 1.25-2.05; P = .0002).RRP alone and EBRT plus ADT provided similar long-term cancer control for patients with high-risk prostate cancer. The authors concluded that continued investigation into the differing impact of treatments on quality-of-life and noncancer mortality will be necessary to determine the optimal management approach for these patients.
