A 70-year-old female presented with epigastralgia. Gastrointestinal endoscopic examination showed advanced gastric cancer type 2. Computed tomography(CT)showed a liver tumor of 37mm in segment 6. She was treated with oral S-1, 80 mg/body for 14 days, followed by a 7-day rest, and CDDP 20mg/m2(day 1 and 8). After ten courses of treatment, CT showed reduction of the primary cancer, the liver tumor, and the affected lymph nodes. Then, distal gastrectomy, lymph node dissection, and partial liver resection were performed. The histological diagnosis was no viable cancer cells found in stomach, liver or lymph nodes. One year and 1 month postoperatively, the patient is alive without recurrence.
