Objectives Nasopharyngeal cancer (NPC) is an endemic disease in Taiwan. Prognostic factors the anatomical TNM stage are important for its prognostic stratification. An elevated neutrophil‐to‐lymphocyte ratio (NLR) has been reported to be associated with poor prognosis in various solid tumours. In this study, we analysed the prognostic impact of the NLR in NPC in Taiwan. Design Single‐institution retrospective study. Setting Medical centre. Participants One hundred and eighty patients with NPC treated at the Far Eastern Memorial Hospital, Taiwan, from January 2007 to December 2013. Main outcome measures The association between the clinical or haematological presentations and the prognosis. Results The majority of the 180 patients included in this study were men (80%) and were <65 years old (91.7%). A neck mass (55.6%) was the most common clinical presentation, followed by nasal (39.4%) and aural (30.6%) symptoms. In addition, the majority (75.4%) of patients had advanced stage (III and IV) disease. Patients with a high NLR (≧3.6) had significantly lower progression‐free survival, overall survival and disease‐specific survival rates. The association between high NLR and poor prognosis was more pronounced in patients with advanced disease than in those with early‐stage NPC. The results of a multivariate analysis revealed that advanced age, clinical symptoms including headache, diplopia and facial numbness, advanced disease stage, and high NLR were independent prognostic factors. Conclusion A high NLR is an independent poor prognostic factor of NPC in Taiwan.
