THE EFFECT OF PRETREATMENT NEUTROPHIL/LEUCOCYTE RATIO ON SURVIVAL IN PATIENTS WITH LOCALLY ADVANCED ESOPHAGEAL CANCER RECEIVING CHEMORADIOTHERAPY

Abstract

Introduction: Esophageal cancer (EC) is a highly lethal malignancy. The majority of esophageal cancers are squamous cell or adenocarcinomas. Although the incidence of squamous cell carcinoma (SCC) is decreasing in the United States, the incidence of adenocarcinoma arising out of Barrett's esophagus is rising dramatically, although less so in the last few years. Treatment in locally advanced EC (LA-EC) must be multidisciplinary. There are only few factors which affects the prognosis. Our aim was to investigate the prognostic and predictive roles of pretreatment neutrophil/leucocyte (neu/leu) ratios in LA-EC patients receiving chemoradiotherapy (CRT).
