[A case of complete response after treatment with UFT and leucovorin for synchronous multiple liver metastases of rectal cancer].

The patient was a 55-year-old female who had multiple liver metastases of rectal cancer. This patient underwent hepatic arterial infusion chemotherapy after low anterior resection for rectal cancer. Hepatic arterial infusion was discontinued due to severe diarrhea, and the administration of UFT (300 mg/day) and LV(75 mg/day) was then begun. The carcinoembryonic antigen (CEA) level was normalized immediately after the start of this administration. One year later, liver metastases disappeared on computed tomography (CT) and a complete response (CR) was achieved. No adverse events were noted, and CR was maintained for 2 years. This therapy can serve as one of the chemotherapies for advanced colorectal cancer.
