 Early gastric carcinoma of differentiated and undifferentiated mixed type was considered, using 508 early gastric carcinomas surgically resected from 2002 to 2006 in Shizuoka Cancer Center. We examined relationships between clinicopathological features and the rate of lymph node metastasis. There were statistically significant differences between purely differentiated type and mixed type (in which differentiated type were predominant) in tub 2, gender, size of the lesion and lymphovascular involvement. It was found that the rate of lymph node metastasis in mixed type (in which the differentiated type was predominant) was higher than that in the purely differentiated type. In this study, there was no lymph node metastasis regardless of ulceration and size of tumor in mixed typed cancers (in which differentiated type was predominant) with depth M and no lymphovascular involvement. ESD treatment for differentiated and undifferentiated mixed type of adenocarcinoma needs to be investigated further, because there are fewer cases on, which to base our conclusions.
