Increasingly, patients with regional (N1) and distant (M1) metastases are being considered for definitive local therapy. We investigated the oncologic outcomes of surgery for patients categorized as HR, very-high risk (VHR), or with suspected metastatic (N1 and/or M1) PCa at the time of RP. METHODS: The MUSIC registry was queried for all RP from 1/2012 to 12/ 2018. Of the 9208 patients, 2023 patients (22%) were classified as having HR PCa or higher. HR PCa was defined as having PSA≥20 or cT3-4 or biopsy grade group (bGG) 4-5;VHR PCa was defined as having ≥2 HR features, or >4 cores of bGG 4-5, or primary pattern 5. Metastatic PCa was defined as clinical N1 and/or M1 disease. The pre-treatment and oncologic outcomes of the HR, VHR, and metastatic groups were compared. Kaplan-Meier analysis of biochemical recurrence (BCR) and multivariable analyses were performed with significance set at p<0.05. RESULTS: At median follow-up of 20.8 months after RP, overall 3-year BCR-free probability was 66% for HR, 49% for VHR, and 47% for metastatic PCa patients (p<0.001). In multivariable analysis, the highly significant (p<0.001) predictors of BCR included PSA (Hazard Ratio: 3.35 (95%CI:2.32,4.83) for PSA>50, 2.35 (1.87,2.96) for PSA 20-50, and 2.07 (1.71,2.51) for PSA 10-20 vs. PSA<10) and risk group (1.63 (1.22,2.18) for metastatic and 1.45 (1.18,1.77) for VHR vs. HR). bGG 3-5, cT2-T4, and African-American race were significant BCR predictors. CONCLUSIONS: Nearly 25% of RP were performed for HR or higher PCa. Although these patients are clearly at higher risk for BCR and many received additional treatments for PCa, the majority are disease-free 3 years after surgery. RP appears to be an oncologically-sound approach for patients with HR and VHR PCa. Patients with suspicion of N1 or M1 disease that undergo RP appear to have similar oncologic outcomes to non-metastatic VHR patients. The value of local treatment in the setting of confirmed metastatic disease is the focus of ongoing clinical trials, and is best performed in this setting.
