Introduction: This study aims to investigate the prognostic significance of pre-treatment hemoglobin-red blood cell distribution width (RDW) ratio (HRR) in terms overall survival (OS) and disease-free (DFS) patients with locally advanced nasopharyngeal cancer (LANC) treated chemoradiotherapy. Methods: Patients LANC who attended oncology clinic between October 2010 June 2020 were retrospectively screened. HRR was calculated as hemoglobin (g/dL) divided by RDW (%). assigned either low group or...
