RESUMEN
INTRODUCTION: The aim of this study was to investigate the prognostic significance of the preoperative neutrophil-to-lymphocyte ratio in non-metastatic renal cell carcinoma. PATIENTS AND METHODS: We retrospectively analyzed the records of patients with non-metastatic renal cell carcinoma who were operated between 2004 and 2020 at our institution. The Kaplan-Meier method was utilized to graphically display survivor functions. Univariate and multivariate Cox's proportional hazards regression models were utilized to analyze the association between neutrophil-to-lymphocyte ratio and oncological outcomes. RESULTS: We included 202 patients. Patients with higher neutrophil-to-lymphocyte ratio had larger tumors (P=0.03), higher ASA score (P=0.014), clinical symptoms (P=0.04), sarcomatoid differentiation (P=0.03) and tumor necrosis (P=0.02). The rates of recurrence-free survival and metastasis-free survival were significantly lower in patients with a high neutrophil-to-lymphocyte ratio than in those with a low ratio (P=0.017; P=0.036 respectively). Multivariate analysis identified the neutrophil-lymphocyte ratio as an independent predictor of recurrence-free and metastasis-free survival (P=0.021; P=0.001 respectively). CONCLUSION: A higher neutrophil-to-lymphocyte ratio has been associated with a symptomatic renal cancer with a significant prognostic factor for both recurrence-free and metastasis-free survival. LEVEL OF PROOF: 3.

Malakoplakia is a rare inflammatory condition that can affect many organ systems, including genitourinary tract, it is associated with impaired immune function. It is characterized by distinctive Michaelis-Gutmann bodies. Very rare cases have been reported to present as a locally advanced renal mass.
