Partial nephrectomy is not associated with an overall survival advantage over radical nephrectomy in elderly patients with stage Ib‐II renal masses: An analysis of the national cancer data base

BACKGROUND Partial nephrectomy (PN) is recommended for localized T1a (≤4 cm) renal masses and is preferred over radical nephrectomy (RN) for amenable T1b/T2 (>4 cm) tumors. The objective of the current study was to assess overall survival (OS) differences between PN and RN in patients with T1 and T2 renal cell carcinoma (RCC). METHODS The National Cancer Data Base was queried for patients with T1 and T2 RCC who underwent PN or RN from 2004 to...
