497Background: Although several guidelines outline management options for patients with renal masses, few studies describe treatment strategies and outcomes in octogenarians. We sought to review outcomes in this population managed with active surveillance (AS), partial nephrectomy (PN), or radical nephrectomy (RN). Methods: Data were collected on 113 octogenarian patients referred for management of renal masses at Moffitt Cancer Center between 2000 and 2013. Patients were treated with AS, PN, or RN. Univariate and multivariable Cox regression models measured association of management modality and survival. Kaplan-Meier survival analysis was used for overall survival and log-rank tests were used to compare survival curves. Covariates include age, Eastern Cooperative Oncology Group (ECOG) score, clinical and pathologic stage, tumor size, creatinine, creatinine clearance, and overall survival. Results: Out of 113 patients, 27 (22%) underwent AS, 33 (26.8%) underwent PN, and 53 (43%) underwent RN. The mean ag...
