Childhood cancer survivors (CCSs) from high-grade malignancies, such as high-risk neuroblastoma, have been increased, and second malignant neoplasm, becomes a serious problem for CCSs. However, detailed reports about rare types of second cancer such as gastric cancer remain limited. We herein reported a female patient who developed diffuse type gastric carcinoma after 21 years from completion of treatment to high-risk neuroblastoma. We reviewed the previous cohort studies for second gastrointestinal cancer in CCSs and the case reports with second gastric carcinoma for CCSs. We presumed second gastric cancer was refractory for CCSs as well as for adult cancer survivors.
