title: [A case of advanced rectal cancer responding to radiation therapy and chemotherapy with S-1].
abstract: We report a case of a 72-year-old man with advanced rectal cancer who refused an operation for cancer therapy. We underwent radiation therapy (40 Gy) for the purpose of suppressing tumor bleeding. Consequently, we administered S-1 (100 mg/day) orally. As a result, the tumor has disappeared by radiation therapy and chemotherapy with S-1 for 2 years. We have recognized no side effects. This therapy seemed to be an effective treatment for poor-risk elderly patients.
