Abstract
Early-stage esophageal cancer is almost asymptomatic. The endoscopic findings are
minimal, and there is no esophageal stenosis. However, a risk of malignant propagation
into vessels and lymph nodes is present in small tumors. Endoscopic destruction or
resection should be performed only at the predissemination stage. We present here
a critical analysis of whether endoscopic detection and treatment is feasible and
efficacious, based on the pathology of esophageal tumors.
