 In the case of positive vertical margin of submucosal cancer in EMR, is there necessity for radical operation? We evaluated the relationship of vertical margin and lymph node metastasis, residue of cancer in the colon and rectum. In our investigation, we focused on 45 submucosal colorectal cancers. Lymph node metastasis was found in 5 cases(11.1%), 4 of which were positive or almost positive for vertical margin. Residue of cancer in the resected colon and rectum after EMR was found in 2cases(5.7%), one of which was positive and another was almost positive for vertical margin. So, in cases of positive or almost positive vertical margin of submucosal cancer in EMR, radical operation is necessary.
