 To elucidate therapeutic strategy and clinical courses of SGCTs(sporadic type of gastric carcinoid tumors), 30cases with them were collected through a questionnaire survey of 10 institutions in Japan. SGCTs 5mm or less in size were not observed metastasis. The MR(metastatic rate)of SGCTs 11mm or larger in size were significantly higher compared with the MR of SGCTs 10mm or less(p=0.042). There was no significant difference between the MR of SGCTs with NET(neuroendocrine tumor)G1 and that with NET G2, however the MR of SGCTs with NEC(neuroendocrine carcinoma)were significantly higher than that of NET G1+G2(p=0.018). The MR of SGCTs invaded to the proper muscularis were significantly higher compared with that of SGCTs located mucosa or submucosa(p=0.049). On the other hand, there was no significant difference between the MR of SGCT with and without invasion to vessels(p=0.072), but SGCT with invasion to vessels had the tendency of high MR.

 Indications of endoscopic treatment for SGCTs were considered to be as follows ; 1)10mm or less in size, and 2)NET G1 or NET G2 of histological type. Furthermore, we should undergo endoscopic ultrasonography to evaluate the depth of lesions before endoscopic removal.
