Is More Always Better? An Assessment of the Impact of Lymph Node Yield on Outcome for Clinically Localized Prostate Cancer with Low/Intermediate Risk Pathology (pT2-3a/pN0) Managed with Prostatectomy Alone

BACKGROUND: The clinical impact of lymph node dissection extent remains undetermined in the contemporary setting, as reflected in care pattern variations. Despite some series demonstrating a direct relationship between number of lymph nodes identified and detection of nodal involvement, the correlation between lymph node yield and disease control or survival outcomes remains unclear. METHODS: Patients with clinically localized prostate cancer, pre-RP PSA
