title: [FT, 5-FU and uracil concentrations of the blood, bile and tissue of hepatoma with liver cirrhosis after oral administration of UFT].
abstract: UFT was orally administered to eight patients with hepatocellular carcinoma (HCC) combined with liver cirrhosis and to five patients with normal liver. The concentrations of FT-207 (FT), 5-FU, and uracil in blood, tissue and bile were then respectively determined. The FT level in cancer tissue and non-cancer tissue was almost identical in patients with HCC. On the other hand, the 5-FU level in normal liver tissue was significantly higher (P less than 0.05) than that in cancer tissue, and the uracil level in normal liver tissue was lower than that in cancer tissue (P less than 0.05). Transportation of FT from blood to liver was significantly correlated with clearance of indocyanine green from the blood (ICGK). These results suggested that transportation of FT from blood to liver and activation of FT were impaired in HCC with liver cirrhosis. However, the 5-FU level in the cancer tissue of HCC tended to be higher than that in non-cancer tissue. The 5-FU level in the tissue had a significant correlation with the FT level in the tissue. In addition, it was presumed that cancer tissue was able to produce 5-FU from FT more quickly than non-cancer tissue.
