Abstract
OBJECTIVES: We aimed to determine the prognostic value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) in patients with laryngeal squamous cell carcinoma (LSCC). DESIGN AND SETTING: A retrospective analysis of patients with LSCC was conducted in our hospitals. Clinical information, including age, sex, TNM classification and other demographic and clinical data, was acquired and analysed. Progression-free survival (PFS) and overall survival (OS) were calculated and compared using the Kaplan-Meier method and log-rank test. PARTICIPANTS: A total of 147 patients with LSCC were included. RESULTS: According to the receiver operating characteristic (ROC) curve, the optimal cut-off points for NLR, PLR and SII were 1.88, 117.36 and 517.64. The analysis revealed NLR, PLR and SII to be independent predictors for OS and PFS (P < .05). CONCLUSIONS: Preoperative NLR, PLR and SII are promising prognostic predictors for patients with LSCC.
