 The vascular involvement, tumor invasion of the cut end, lymph node metastasis and prognosis of seventeen cases of gastric sm cancer resected by EMR were analyzed by the depth of invasion. As for the lymph vessel invasion, only two out of seven cases (28.6%) with sm invasion less than 500 μm in depth had lymphatic vessel invasion compared to nine out of 10 cases (90%) with sm invasion deeper than 500 μm. All of the five cases with tumor invasion of the cut end (submucosal surface) had invasion deeper than 1,000 μm. Local recurrence and/or remnant were found in two cases, and lymph node metastasis was detected in one case. The submucosal layer of the EMR specimens was rough and was likely to be judged thicker, therefore criteria of the microinvasion might be changed to 500 μm in depth. So-called burning effect should be taken into consideration for the judgement of remnant of tumor at the cut end.
