 With advancement of endoscopic treatment for early gastric carcinoma, expansion of the list of lesions indicated for endoscopic resection (ER) is being explored. For expanded use of ER in the future, importance it attached not only to accurate preoperative detection of lymph node (LN) metastasis from diagnostic imaging, but also to accurate postoperative prediction of LN metastasis from molecular analysis of ER specimens. At present, ER is indicated for a group of lesions identified for their statistically low probability of LN metastasis by the clinicopathological analysis of patients who have undergone surgical operation for early gastric carcinomas. Therefore, the possibility of LN metastasis cannot be ruled out completely even in the group with a significantly lower risk of LN metastasis. On the other hand, it is also a fact that there are lesions curable by ER but which are excluded from the general indication for ER because of the risk of LN metastasis. Expansion of the list of eligible lesions indicated for ER from a statistical view is approaching the limit. Expanded use of ER for early gastric carcinoma will be difficult unless problems, such as how accurately LN metastasis can be detected before ER and predicted after ER in individual patients, are solved.
