Regular screening of esophageal cancer for 248 newly diagnosed hypopharyngeal squamous cell carcinoma by unsedated transnasal esophagogastroduodenoscopy

摘要

Objectives: Esophageal squamous cell carcinoma (ESCC) is common in hypopharyngeal squamous cell carcinoma (HSCC) patients. This prospective study is to reveal the prevalence of simultaneous ESCC in newly diagnosed HSCC patients by unsedated transnasal esophagogastroduodenoscopy (EGD) and to analyze the clinical predictors for simultaneous esophageal lesions and their survival.
