ABSTRACT
Barrie Rathbone,1 Janusz Jankowski,2 Michael Rathbone31University Hospitals of Leicester, Leicester, 2Sir James Black Professor Queen Mary University of London, 3St George's University of London, London, United KingdomAbstract: Esophageal cancer is the sixth commonest cause of cancer death worldwide. It predominantly occurs in two histological types, ie, squamous cell carcinoma and adenocarcinoma, each with its own distinct geographical distribution and natural history. The incidence of esophageal adenocarcinoma is rising, as is that of its precursor lesion, Barrett's esophagus, which consists of metaplastic change in the squamous mucosa of the esophagus in response to damage by gastroesophageal reflux disease. The principal risk factors for esophageal cancer are cigarette smoking and alcohol consumption, reflux disease, and obesity. In tumors without local invasion or distant metastases, surgery remains the treatment option of choice, although there are considerable differences of opinion regarding the roles of chemotherapy and radiotherapy. A wide variety of endoscopic treatments are available for dysplastic lesions and palliation. Despite the availability of increasingly complex imaging modalities and expensive and possibly ineffective attempts at screening, the evidence base is conflicted and the prognosis remains poor. However, from a recent large systematic review, three clear recommendations can be made, ie, use of endoscopic resection for high grade dysplasia, use of radiofrequency ablation for residual premalignant lesions, and, finally, prevention of risk factors for cancer, such as smoking, alcohol consumption, and obesity.Keywords: cancer, Barrett's, esophagus, squamous cell carcinoma, adenocarcinoma
