Surveillance of patients at high-risk of squamous cell esophageal cancer

文摘
Currently curative treatment for esophageal squamous cell cancer (ESCC) is possible only in patients with early-stage, usually asymptomatic disease. In Western countries, where the incidence of ESCC is relatively low, a screening of asymptomatic, average-risk population is untenable. In order to detect early-stage ESCC or its precursor lesions it is important to identify high-risk patients and consider endoscopic surveillance in these groups. These high-risk groups include patients after curative treatment for head and neck cancer, previous endoscopic resection of ESCC, caustic injury, and patients with tylosis or achalasia. This paper discuss the evidence and proposed method of endoscopy surveillance of these high-risk patients.
