 The relationship between superficial early cancer and advanced cancer is interesting, however, there has been no evidence but speculations to demonstrate it. We designated superficial type tumors from the both morphological and histological viewpoints. Histological designation of superficial type tumor was that there was horizontal growth of cancer in the residual mucosa. Those cancers with the following features were regarded arising from superficial type tumors : 1) Invasion was deeper than the sm layer, 2) Their macroscopic shape was other than superficial type, and 3) Histological examination showed horizontal growth of cancer in the mucosa. The rates of arise from superficial tumor in each groups of depth of invasion were as follows : submucosal cancer ; 29.4%, muscularis propria cancer ; 7.1%, cancer with invasion deeper than the subserosa layer ; 2.3%. The cancer with invasion deeper than the muscularis propria layer usually loose cancer in the mucosa, therefore, the rates may not reflect actual incidence. The rate of submucosal cancer may be close to the actual rate at present. It may be useful to focus on the horizontal growing tumor of the colon for understanding the advance and development of colon tumors. At present horizontal growth would be considered in addition to flat neoplasm (FN), however, the essence of FN is horizontal growth, therefore, we strongly suggest that superficial tumor should be designated only by horizontal extension without FN.
