Abstract
BACKGROUND: Emerging evidence indicate that inflammation plays a crucial role in carcinogenesis and tumor progression. Inflammatory response biomarkers are recognized as promising prognostic factors in laryngeal squamous cell carcinoma (LSCC). OBJECTIVE: To evaluate the prognostic significance of preoperative derived neutrophil-to-lymphocyte ratio (dNLR) in patients with total laryngectomy. METHODS: This was a retrospective analysis of 137 patients with LSCC who received total laryngectomy from January 2009 to December 2015. The preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and dNLR were calculated. Receiver-operating characteristic (ROC) curve was used to determine the cut-off values of these parameters. Univariate analysis and multivariate Cox regression model were used to evaluate the association between these parameters and recurrence-free survival (RFS) and overall survival (OS). RESULTS: The optimal critical value of dNLR was 1.85, by which cases were divided into high dNLR group (dNLR ≥ 1.85) and low dNLR group (dNLR < 1.85). The elevated dNLR was significantly associated with decreased RFS (HR 2.72, 95% CI 1.56-4.75, p = .000) and remained significant in multivariate analysis (p = .034). However, we did not find any significant correlation between dNLR and OS. CONCLUSIONS: An elevated preoperative dNLR may be an independent prognostic biomarker for RFS in patients undergoing total laryngectomy with LSCC.
