 Gastric NETs complicated with type A gastritis are classified as type I gastric NETs. Type I gastric NETs are small in size, many in number, and histologically well-differentiated ; therefore, they have a good prognosis. Many past reports, including those from Japan, have reported these characteristics. However, it has recently been reported that type I gastric NETs complicated with lymph node and liver metastasis exist with a low incidence. The clinical features of such type I gastric NETs are as follows:1)tumor diameter ≧10mm, 2)high Ki-67 index, and 3)invasion beyond submucosa. Currently, a total of 200 cases have been registered and analyzed for studying type I gastric NET in Japan.
