ABSTRACT
Abstract

Introduction:

Systemic inflammatory biomarkers are promising predictive and prognostic factors for solid cancers. The neutrophil-lymphocyte ratio and derived neutrophil-lymphocyte ratio are used to predict inflammation and used as biomarker in several malignancies.

Objective:

The purpose of this study was to demonstrate the diagnostic, predictive and prognostic role of neutrophil-lymphocyte ratio and derived neutrophil-lymphocyte ratio in patients with laryngeal neoplasms.

Methods:

A retrospective study was conducted on medical records involving 229 patients with benign, premalignant and malignant laryngeal neoplasms between 2002 and 2015. The diagnostic, predictive and prognostic role of neutrophil-lymphocyte ratio and derived neutrophil-lymphocyte ratio were evaluated using uni- and multivariate analysis.

Results:

The neutrophil-lymphocyte ratio and derived neutrophil-lymphocyte ratio were not statistically different between patients with benign, premalignant and malignant laryngeal neoplasms. Both neutrophil-lymphocyte ratio and derived neutrophil-lymphocyte ratio were predictive factors for stage, lymph node metastasis, and distant metastasis. Patients with high neutrophil-lymphocyte ratio value (≥4) had a poor prognosis when compared with patients with low neutrophil-lymphocyte ratio value (5 year, Overall Survival 69.0% vs. 31.1%, p < 0.001; 5 year, disease free survival 70.0% vs. 32.7%, p ˂ 0.001; 5 year, locoregional recurrence free survival 69.7% vs. 32.0%, p < 0.001). Furthermore, neutrophil-lymphocyte ratio was an independent prognostic factor for 5 year Overall survival (HR = 2.396; 95% CI 1.408-4.077; p = 0.001), Disease free survival (HR = 2.246; 95% CI 1.322-3.816; p = 0.006) and locoregional recurrence free survival (HR = 2.210; 95% CI 1.301-3.753; p = 0.003).

Conclusion:

Pretreatment neutrophil-lymphocyte ratio is a useful and reliable predictive and prognostic biomarker for patients with laryngeal carcinoma.
RESUMO
Resumo

Introdução:

Biomarcadores inflamatórios sistêmicos são fatores preditivos e prognósticos promissores para cânceres sólidos. A relação neutrófilo-linfócito e a relação neutrófilo-linfócito derivada são utilizadas para predizer a inflamação e como biomarcadores em várias malignidades.

Objetivo:

O objetivo deste estudo foi demonstrar o papel diagnóstico, preditivo e prognóstico da relação neutrófilo-linfócito e relação neutrófilo-linfócito derivada em pacientes com neoplasias laríngeas.

Método:

Foi realizado um estudo retrospectivo em prontuários médicos de 229 pacientes com neoplasias laríngeas benignas, pré-malignas e malignas entre 2002 e 2015. O papel diagnóstico, preditivo e prognóstico da relação neutrófilo-linfócito e relação neutrófilo-linfócito derivada foi avaliado por meio de análise uni- e multivariada.

Resultados:

A relação neutrófilo-linfócito e a relação neutrófilo-linfócito derivada não foram estatisticamente diferentes entre pacientes com neoplasias laríngeas benignas, pré-malignas e malignas. Ambas as relação neutrófilo-linfócito e relação neutrófilo-linfócito derivada foram fatores preditivos para o estágio, metástase linfonodal e metástase a distância. Pacientes com valor alto da relação neutrófilo-linfócito (≥ 4) apresentaram pior prognóstico quando comparados com pacientes com valor mais baixo da relação neutrófilo-linfócito (5 anos, Sobrevida Global 69,0% vs. 31,1%, p < 0,001; 5 anos, sobrevida livre de doença 70,0% vs. 32,7%, p < 0,001; 5 anos, sobrevida livre de recorrência loco-regional 69,7% vs. 32,0%, p < 0,001). Além disso, a relação neutrófilo-linfócito foi um fator prognóstico independente para 5 anos Sobrevida global (HR = 2,396; IC95% 1,408-4,077; p = 0,001), sobrevida livre de doença (HR = 2,246; IC95% 1,322-3,816; p = 0,006) e sobrevida livre de recorrência loco-regional (HR = 2,210; IC95% 1,301-3,753; p = 0,003).

Conclusão:

A relação neutrófilo-linfócito no pré-tratamento é um biomarcador preditivo e de prognóstico útil e confiável para pacientes com carcinoma de laringe.
