Neutrophil–Lymphocyte Ratio as a Prognostic Factor in Laryngeal Carcinoma

Aim of this study; investigate whether neutrophils/lymphocyte ratio (NLR) could be used as a prognostic factor in larynx cancer. The correlation between preoperative peripheral blood NLR and age, gender, smoking, alcohol use, clinical stage and differentiation degree was examined. One hundered fourty-four patients in Dicle University Department of Otorhinolaryngology between the years of 2005 and 2014 were included in the study. Clinical and preoperative laboratory data of patients were screened retrospectively from archive files of otorhinolaryngology and the pathology results were screened retrospectively from archive files of pathology. The study was approved by the local ethics committee of the department and carried out in accordance with the declaration of Helsinki as amended in 2013. Statistical analyses were performed using the SPSS 15.0 software package for Windows (SPSS inc., Chicago, IL, USA). There was a significant difference between NLR and clinical stage (p = 0.003) smoking (p = 0,001) and alcohol use (p = 0.001). When NLR was analyzed in detail according to the degree of tumor differentiation; significant differences were observed between G1 and G2 (p = 0.007) and between G1 and G3 (p = 0.001). Light of these findings, NLR is a cheap and easily accessible marker which can be used as a prognostic faxtor in laryngeal cancer. It is thougkt to shed light on the studies which will be conducted with more patients.
