The Experience of the Intensity Modulated Radiation Therapy for Abdominal Lymph Node Metastases from Gastric Cancer

: The recurrence ofgastric cancer has a poor prognosis in spite ofsystemic chemotherapy. We report three cases oflocal control ofdisease after the recurrence owing to intensity modulated radiation therapy(IMRT). The first case was a 66-yearsold man. He was received distal gastrectomy after neoadjuvant chemotherapy for advanced gastric cancer. Abdominal lymph node metastases appeared 1 year and 7 months after the surgery. IMRT was performed and he keeps CR for 1 year and 8 months. The second case was a 72-years-old man. He received proximal gastrectomy for early gastric cancer. Abdominal lymph node metastasis appeared 1 year and 9 months after the surgery. IMRT was performed and he keeps CR for 1 year. The third case was a 71-years-old woman. She received distal gastrectomy for advanced gastric cancer. Abdominal lymph node metastasis appeared 2 years after the surgery. IMRT was performed and she keeps CR for 10 months. We experienced longtime CR after IMRT against abdominal lymph node metastasis. IMRT could be one ofthe strategies ofthe comprehensive treatment for the recurrence of gastric cancer.
