title: A prospective randomized administration of 5'-deoxy-5-fluorouridine as adjuvant chemotherapy for hepatocellular carcinoma treated with transcatheter arterial chemoembolization.
abstract: A prospective randomized trial was conducted to evaluate the efficacy of long-term oral administration of low-dose 5'-deoxy-5-fluorouridine (5'-DFUR) as an adjuvant chemotherapy, following transcatheter arterial embolization (TAE) in 40 patients with hepatocellular carcinoma (HCC). Forty eligible patients were randomized into two groups: 20 with TAE plus 5'-DFUR (400 mg/day) and 20 with TAE alone. A good necrosis rate or decrease in size of more than 70% of the original tumor mass was attained in 14 by the TAE plus 5'-DFUR arm, and in 12 by the TAE arm at 3 months after the first TAE. Although all five patients with HCC and 70-99% necrosis rate after the first TAE in the TAE alone arm showed a less than 70% necrosis rate at 12 months, four of the seven patients with a 70-99% necrosis in the TAE plus 5'-DFUR arm retained a necrosis of more than 70% at 12 months after the first TAE. The appearance rate of ascites and/or encephalopathy in patients with chemotherapy was not different from that of patients with TAE alone. One-year survival rates in the TAE plus 5'-DFUR arm and the TAE alone arm were 75.0% and 85.0%, 2-year rates were 64.2% and 66.2%, and 3-year rates were 64.6% and 49.7%, respectively. There was no significant difference in the survival curves. In conclusion, adjuvant therapy with 5'-DFUR was well tolerated without significant side effects, and it might maintain a good necrosis state of HCC after TAE. In order to confirm a beneficial effect of the chemotherapy on the survival period, a study using more patients and longer observation periods will be required.
