[Report of two cases successfully treated by chemo-radiation against lymph node metastasis after gastric cancer surgery].

A 68-year-old male patient with mediastinal node metastasis 40 months after total gastrectomy for advanced gastric cancer, and a 72-year-old male patient with para aortic node metastasis were treated with concurrent chemo-radiotherapy of 1.8 Gy × 5 × 6 week with S-1 (100 mg/body, days 1-14 and 22-35) + docetaxel (30 mg/body, days 1, 8, 22, 29). Although two patients developed a lymph node recurrence during multiple chemotherapies including S-1, they have responded well and demonstrated complete response after chemo-radio therapy. Grade 3 esophagitis was sole adverse side effect. In contrast to the western countries, chemo-radio therapy was not recognized as a standard treatment for gastric cancer in Japan. However, our report suggested that chemo-radio therapy can be an option for the treatment of advanced gastric cancer.
