The patient was a 77-year-old man. He was diagnosed with Stage IV gastric cancer with pancreatic invasion and pyloric stenosis. After gastrojejunostomy, S-1 monotherapy was started. Melena and fatigue appeared 2 months after chemotherapy, and Grade 3 anemia was confirmed. Palliative radiotherapy of 30 Gy in 10 Fr was administered to control bleeding from the lesion. The progression of anemia stopped and outpatient chemotherapy became possible. Palliative radiotherapy for persistent bleeding from unresectable advanced gastric cancer is considered an effective treatment option to control bleeding.
