title: [Current topics and endoscopic characteristics of the diagnosis how to detect in early gastric or colon cancer].
abstract: It is now an era of diversity of treatment for early cancer. Endoscopic diagnosis for both early gastric and colon cancer have focused on the detection of small or minute cancers(smaller than 5 mm), which could be resected by endoscopically. It has been generally considered that endoscopic curative treatment for the small cancer (smaller than 10 mm) is useful from the data of lymph node metastasis in early gastric cancer, however, a high incidence of recurrence (7.5 approximately 22.9%) after endoscopic mucosal resectomy has been found. High cancer rates and high rates of sm invasion are recognized in the superficial type, especially IIc, IIc + IIa, IIa + IIc, of colon tumor. The degree of invasion should be defined and a criteria for indication of endoscopic treatment should be determined from the endoscopic findings.
