 Remarkable advances in clinical and pathological evaluation of superficial esophageal cancer have been achieved in the last thirty years in Japan. Upper gastrointestinal endoscopy aided by iodine staining made possible the surveillance of esophageal cancer and many patients with mucosal cancer have been detected. Because of the frequent occurrence of mucosal cancers of the esophagus clinical and pathological estimation of them improved significantly and resulted in treatment by endoscopic mucosal resection (EMR) in 1989. The clinical result of EMR for mucosal cancer was excellent and was accepted as the alternative to the radical esophagectomy. The gross classification of superficial esophageal cancer facilitated the differentiation of mucosal cancer from submucosal cancer. The subclassification of the depth of cancer invasion and developments in endoscopic ultrasonography (EUS) using 20 MHz also encouraged further research on superficial esophageal cancer. Esophagography had not been an important measure in either early detection or clinical estimation of mucosal cancer of the esophagus, but, recently, x-ray study has become recognized as a reliable means for the clinical estimation of m3 and sm1 esophageal cancers. EUS has played a leading role in the clinical estimation of lymph node metastasis.
