A 53-year-old-man, who suffered from advanced gastric carcinoma with liver metastasis (P0H3S2N1; stage IV) underwent simple gastrectomy. After the operation, the patient was treated by chemotherapy (1/2 MFC, M: mitomycin C, F: FT-207, C: Cylocide) combined with immunotherapy (PSK, lentinan) and intraarterial injection (mitomycin C & Lipiodol). Liver metastases disappeared soon after the combined therapy, and these findings were confirmed by CT and US. Moreover, the serum level of CEA and CA 19-9 also decreased from 160 ng/ml and 51 U/ml to the normal level. The duration of the complete disappearance of the liver metastasis was not so long, but quality of life was well maintained for 2 and one half years. This case suggested that combined therapy may well be effective for advanced gastric cancer with liver metastases.
