Abstract

Abstract : Supplemental Digital Content is available in the text Abstract : Abstract: There is increasing evidence that the neutrophil-to-lymphocyte ratio (NLR) is a stage-independent predictor of poor outcome in patients with cancer. The purpose of this study was to investigate the association between cancer-specific survival (CSS), overall survival (OS), and the preoperative NLR in patients with advanced laryngeal squamous cell carcinoma (LSCC) undergoing total laryngectomy (TL). All patients with a new diagnosis of advanced laryngeal cancer (stages III and IV) presenting at the Department of Head and Neck Oncology, Sun Yat-sen University Cancer Center between January 1990 and July 2010 (n = 420) were included. To evaluate the independent prognostic relevance of the NLR, univariate and multivariate Cox regression models were used. CSS and OS were estimated using the Kaplan-Meier method. Four-hundred twenty patients were enrolled in this study. Patients with an NLR ≥2.59 showed a significantly lower CSS ( P = .014) and OS ( P = .032) than patients with an NLR <2.59. The Cox proportional multivariate hazard model showed that a higher preoperative NLR was independently correlated with a poor CSS and OS, with hazard ratios of 1.42 (95% confidence interval [CI] 1.06–1.91, P = .018) and 1.31 (95% CI 1.00–1.71, P = .046), respectively. The NLR may be an independent prognostic marker for CSS and OS in patients with advanced LSCC undergoing TL.
