A 78-year-old female patient with locally advanced breast cancer, bleeding from a deep ulcer, and with multiple bone, lung and distant lymph node metastases was successfully treated with 5'-DFUR alone. She was at first treated with docetaxel + 5'-deoxy-5-fluorouridine (5'-DFUR) + tamoxifen, but they were discontinued because of deep venous thrombosis. She underwent simple mastectomy due to periodically recurring bleeding and infection. After administration of 5'-DFUR alone, a decrease of abnormal accumulation on a bone scintigram was obtained in 10 months, the lung metastases were diagnosed as being in complete remission (CR) at 11 months and the lymph node metastases were diagnosed as being in CR at 14 months. These states have continued to the present. The administration of 5'-DFUR alone is suitable for tumor dormancy in some cases.
