Article Title: Functional and oncological outcomes of renal surgery for hilar tumors: Informing the decisions in risk-adapted management
Abstract: Objective: To describe the safety and efficacy of partial nephrectomy (PN) in comparison to radical nephrectomy (RN) for surgically managed renal hilar tumors. Materials and Methods: We retrospectively reviewed institutional records of patients with a small (<5 cm) solitary renal (hilar or non-hilar) mass who underwent PN or RN between 2008 and 2018. Hilar tumors were defined as those at medial position, abutting the renal vessels. Recurrence-free, cancer-specific, and overall survival were estimated using the Kaplan-Meier method. Results: Of 1,951 eligible patients, 399 had hilar tumors (292 scheduled for PN, 107 RN) and 1,552 had non-hilar tumors (scheduled for PN). We found no significant differences in survival measures between hilar and non-hilar tumors in patients selected for PN. Patients scheduled for PN for hilar tumors had higher rates of ≥grade II postoperative surgical complications compared to patients scheduled to receive PN for non-hilar tumors (13% vs 8.6%; log-rank P =.018) and non-statistically significantly elevated rates of ≥grade II complications compared to patients scheduled for RN for hilar tumors (13% vs 6.5%; difference 6%, 95% CI 0.4%, 13%; log-rank P =.07). Conclusion: PN for hilar and non-hilar renal masses (<5cm) experience comparable oncologic outcomes though increased risk of complications for hilar masses. PN for hilar tumors was associated with better renal function and overall survival with non-statistically elevated risk of grade II or higher complications than RN. A renal tumor located at the hilum should not be a contra-indication for performing PN. © 2021 Elsevier Inc.
