BACKGROUND: To assess the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced non-metastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy.
Material and methods: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, examined data from 478 radical nephrectomies for renal tumors and identified 187 patients with locally advanced non-metastatic ccRCC (pT3-T4 N0M0). The NLR was obtained preoperatively and calculated by dividing the absolute number of neutrophils by the absolute number of lymphocytes. OS and RFS were assessed by the Kaplan-Meier method. Cox proportional hazards regression models were used to assess predictors of RFS and OS.
RESULTS: Among 187 patients with ccRCC (mean age 63.4 ± 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. In univariate analysis, in patients with Fuhrman nuclear differentiation grade 3-4, the median time to recurrence was significantly shorter with NLR ≥ 4 than
CONCLUSION: For patients with locally advanced and non-metastatic ccRCC, RFS was reduced with high nuclear differentiation grade and high preoperative NLR. These results suggest an association between higher NLR and poorer results in locally advanced ccRCCs.
