 As endoscopic technique progresses, endoscopic treatment will become more widely acceptable for submucosal invasive colorectal cancer with deeper invasion(T1b/SM2-CRC). However, in T1b/SM2-CRC, there are foci of DLVI(discontinuous lymphovenous invasion), which is defined as lymphatic and/or venous cancer invasion apart from the invasive front in the deeper layer of the colon. In some cases of T1b/SM2-CRC with DLVI, cancer metastasizes to the liver or lung. In the General Rules for Clinical and Pathological Studies on Cancer of the Colon, Rectum, and Anus, 8th Edition, a revision will be offered concerning the depth of tumor invasion in the colonic layers of DLVI. Therefore, careful consideration of endoscopic treatment for T1b/SM2-CRC taking DLVI into account is necessary.
