The results of treatment of superficial esophageal cancer in 25 patients receiving subtotal esophagectomy and in six patients receiving curative irradiation were evaluated. As a result, the following treatments are recommended for the various endoscopic types of superificial esophageal cancer. The endoscopic types of operated cases consisted of six cases of superficial and protruded type; two cases of superficial and depressed type; 14 cases of slightly depressed type and three cases of flat type. 1) Superficial and protruding type (type 0-I)and superficial and depressed type (type 0-III), as viewed from the recurrent types of postoperative recurrent cases, require subtotal esophagectomy with extensive lymph node dissection of upper mediastinal cervical area. 2) Slightly elevated type (type 0-IIa) and slightly depressed type (type 0-IIc), as viewed from postoperative complications and "quality of life" aspects, subtotal esophagectomy with standard lymph node dissection around the esophagus is recommended. 3) The flat type (type 0-IIb) were all intraepithelium carcinoma with no lymph node metastasis. Consequently, to eliminate operative invasion, extraction of the esophagus without thoracotomy is recommended. 4) From a separate viewpoint, for cases in which severe dysfunction of the organs exist, curative irradiation would be the favored choice.
