A 64-year-old male with advanced gastric cancer with multiple liver metastasis was treated with intensive chemotherapy including mitomycin C and tegafur after palliative gastrectomy. The patient was medicated with 30 mg iv of mitomycin C after surgery and 1,000 mg ir or 1,200 mg po of tegafur for one year for induction therapy and 400-600 mg po of tegafur for long-term maintenance therapy. All metastatic lesions in liver were completely eliminated three years after the start of treatment. As to acute and chronic toxicity, slight leukopenia was noted in the treatment, but the patient was found to show a good quality of life because of less toxicity. The patient has been healthy with no evidence of malignancy at nine years and nine months after the surgery. The total cumulative dose of tegafur in this treatment was 1,141.0 g, which is probably the largest dose ever reported in Japan, suggesting that the combination of mitomycin C and tegafur is indicated as a modality for advanced gastric cancer with liver metastasis.
