ABSTRACT
PURPOSE: This study aimed to investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), and the systemic immune-inflammation index (SII) with the clinical and pathological parameters of 118 laryngeal cancer patients, as well as their effects on the survival of the disease.
METHODS: For the calculation of SII, PLR, and NLR, hemogram tests were conducted before treatment. Receiver-operating characteristic (ROC) analysis was used to calculate the cut-off value of SII, NLR, and PLR for overall survival (OS) and disease-free survival (DFS).
RESULTS: A statistically significant relationship was found between SII and lymphovascular invasion and between NLR and local recurrence, and lymphovascular invasion. In a univariate analysis, SII (p < 0.001) and NLR (p = 0.001) for OS and SII (p < 0.001), PLR (p = 0.043), and NLR (p < 0.001) for DFS were detected as prognostic factors. In a multivariate analysis for OS, SII (HR = 10.54, 95% CI 1.28-86.77; p = 0.029) and extracapsular extension (HR = 3.08, 95% CI 1.15-8.21; p = 0.024) were identified as independent prognostic factors. In a multivariate analysis for DFS, only an extracapsular extension presence (HR = 3.32, 95% CI 1.37-8.08; p = 0.008) was detected as an independent prognostic factor.
CONCLUSION: In laryngeal cancer, high SII values were determined as poor independent prognostic factors for OS. High SII, NLR, and PRL have been identified as poor prognostic factors in DFS. A correlation was found between NLR and local recurrence, and lymphovascular invasion and between SII with lymphovascular invasion positivity.
