[A Case of Abdominal Para-Aortic Lymph Node Recurrence of Gastric Cancer Treated with Radiotherapy, Surviving More Than 5 Years].

A 66-year-old man was diagnosed with advanced type 2 gastric cancer and underwent total gastrectomy. The pathological diagnosis was T3N2H0P0CY0M0, stage ⅢB gastric cancer. Consequently, the patient received adjuvant S-1 therapy for 12 months. Thirty months after the operation, para-aortic lymph node recurrence was evident by computed tomography (CT). As a result, combination chemotherapy with paclitaxel, 5-fluorouracil, and cisplatin was initiated. However, after three courses of chemotherapy, abdominal CT showed progressive disease of the recurrent lymph node. Thereafter, radiotherapy at a total dose of 56 Gy was performed. After the radiotherapy treatment, abdominal CT demonstrated a remarkable reduction of the recurrent lymph node. The patient remains alive, with no signs of relapse, 70 months later. Therefore, this case suggests that radiotherapy may represent an effective treatment for localized remote lymph node recurrence of gastric cancer.
