[Epidermoid cancer of the esophagus: overview]

Abstract

Numerous extrinsic factors are involved in the pathogenesis of esophageal cancer. The disease exhibits clinical symptoms only at the advanced stage, often when no further curative possibilities exist; this delay is one of the main causes of the poor prognosis still associated with esophageal cancer. To secure early diagnosis, contrast GI series and endoscopy should be performed immediately whenever esophageal symptoms are present. Initial assessment of esophageal cancer should in any case include thoraco-abdominal scan. Bronchoscopy is indicated when the tumor is localized in the middle third of the organ. Surgery has long been considered the only valid treatment for esophageal cancer. However, the rule today is a multidisciplinary approach which offers either curative or palliative treatment designed to optimize therapy and minimize side effects. Promising results have recently been obtained with a combination of radiotherapy-chemotherapy followed by esophagectomy.
