[A case of advanced gastric cancer with multiple liver metastases responding completely to hepatic arterial infusion and systemic chemotherapies].

A 41-year-old male complaining of epigastric discomfort visited another hospital for a medical checkup. Gastrointestinal fiberscopic examination revealed a type 3 lesion on the lesser curvature of the lower portion, and biopsy specimens showed tubular adenocarcinoma. Abdominal CT demonstrated multiple liver metastases. After receiving a low-dose FP chemotherapy via IVH catheter for 1 week, the patient undertook a distal gastrectomy accompanied by D2 lymph node dissection. From the 19th postoperative day (POD), hepatic arterial infusion chemotherapy (HAIC) using 5-FU (500 mg/day) plus CDDP (10 mg/day) was performed for about 14 months. On the 47th POD, oral administration of UFT began and continued for 2 years. After 4 months of HAIC, the metastatic lesions of the liver disappeared completely. The patient has been free from recurrence since then for about 2 years. In the peripheral blood, Th1/Th2 ratio and activity of NK/LAK (IL-2 induced) kept increasing during this period. IHAC using 5-FU plus CDDP seems to be an efficient and worthy therapeutic modality if there are no other lesions except multiple liver metastases and a curative gastric resection is indicated.
