An 81-year-old man was referred to our hospital. Upper gastrointestinal endoscopy revealed a type 2 tumor in the antrum of the stomach. The histopathological findings showed a moderately differentiated HER2-negative adenocarcinoma. Two low-density areas of 17mm and 26mm in diameter were observed in the liver S6 and S8respectively at the CT scan. Nine courses of S-1 plus oxaliplatin(SOX)therapy were administered to this patient with gastric cancer and liver metastases. Since both the primary tumor and the liver metastases were significantly reduced by the chemotherapy, distal gastrectomy(D2 dissection)and partial liver resection(liver S6, S8)were performed. The histopathological findings revealed no tumor cells in the primary tumor, lymph nodes, and liver metastases, with a histologic effect of Grade 3. The patient underwent adjuvant therapy with S-1. He has been alive without recurrence for 11 months post-surgery.
