[A case of recurrence with liver metastasis after total gastrectomy for StageIA gastric carcinoma successfully treated with S-1/CDDP combination followed by S-1 chemotherapy].

A 72-year-old man underwent total gastrectomy for gastric carcinoma. Postoperative staging was Stage IA. One year after operation, abdominal CT revealed a metastatic tumor in the left lateral posterior segment of the liver. He was given S-1/ CDDP combination chemotherapy(S-1 120mg/body, day 1-21, CDDP 95mg/body, day 8)every 5weeks as first-line treatment. After 2 courses of the treatment, the liver tumor was not detected by PET-CT. The clinical response was assessed to be complete response. After total 5 courses of the treatment, we changed to a single administration of S-1(120mg/body, day 1- 14)every 3 or 4 weeks as second-line chemotherapy. The effect has been continued for 18 months after the initial metastasis. S-1/CDDP and S-1 chemotherapy are effective for metachronous liver metastasis from gastric carcinoma, although prognosis of the disease is poor.
