Although many prognostic factors have been identified for lung cancers, new ones are needed to determine the course of disease. Recently, a high neutrophil lymphocyte ratio (NLR) prior surgery or treatment has shown be an indicator prognosis cancer. The aim this study was investigate value NLR as factor and correlation between other probable clinical in non small cell cancer patients treatment.Data who were diagnosed with non-small our institution retrospectively reviewed.
