[A case of hepatocellular carcinoma with bone metastasis responding to oral administration of UFT].

A 63-year-old male patient with a mass in the left chest wall was referred to our hospital. An osteoclastic area was found in the mass of the left 4th rib by computed tomography; the mass was hard and little movable. There was an irregular and poorly demarcated low-density area, 5 cm in diameter, in the liver anterior superior segment. Aspiration from the mass of the chest wall indicated adenocarcinoma (class V) and forecast of metastatic lesion. The titer of serum AFP showed an extremely high level of 1,100 ng/ml. According to these findings, the patient was diagnosed as having hepatocellular carcinoma with bone metastasis and treated by the administration of oral UFT (300 mg/day). Six months later, the mass in the left chest wall was completely eliminated, the size of the hepatic lesion changed to 2.5 cm, and the titer of AFP decreased to the normal range (8.4 ng/ml). Treatment of hepatocellular carcinoma with bone metastasis is often ineffective, but this is a rare case showing the clinical effectiveness of oral administration of UFT.
