We report herein a case of heterochronous hepatic metastasis of gastric cancer that responded well to chemotherapy using TS-1. The patient was a 72-year-old man who underwent total gastrectomy for gastric cancer. Liver metastasis (S8, 4 cm in diameter) was found 3 months after surgery. TS-1 (100 mg/day) was administered orally everyday for a total of 33 weeks, after which the liver metastasis showed CR. Grade 2 fever and grade 2 dermatitis were the only adverse reactions observed, and the patient did not require hospitalization by discontinuing TS-1 administration. The present case suggests the usefulness of chemotherapy using TS-1.
