[ Summary ] To clarify the characteristics of advanced cancer originated in laterally spreading tumors (LST), ten cases of LST invading the deeper middle third of the submucosal layer (sm2,3) into the proper muscle layer (mp) were selected from 127 LST cases for this study. Three cases of sm2,3 and three cases of mp out of 68 cases of the granular type (8.8%) and four cases of sm2,3 out of 59 cases of the non-granular type (6.8%) were investigated. It was suggested that in the granular type, invasion into the deeper layer might have occurred with nodular formation in large LST ranging from 20 to 70mm in diameter. The non-granular type appeared to present deep invasion with minimal change of features in smaller LST in size.
