title: [Effect of fluoropyrimidine, drugs of tegafur and UFT on transplanted tumor in liver-damaged mice].
abstract: 1-(2-Tetrahydrofuryl)-5-fluorouracil (FT) and UFT are masked compounds of 5-fluorouracil (5-FU) and considered to be gradually metabolized and converted to 5-FU in the liver. Therefore, it is important clinically to classify whether or not these anti-cancer drugs are effective in individuals with liver diseases. BALB/c mice were injected 4 ml/kg of 10% CCl4 intraperitoneally twice a week for two months to induce liver damage. On the 49th day after starting of giving CCl4, mouse sarcoma 180 was transplanted to the right thigh of mice and from the next day 5-FU (10, 20, 30 mg/kg/day), FT (50, 100, 200 mg/kg/day), UFT (10, 20, 30 mg/kg/day) or physiological saline solution for control were orally administered daily for 7 days. On the 61st day, all mice were sacrificed and the weight of excised tumor was measured to judge the effect of anti-cancer drugs. Dose-dependent effect of 5-FU was observed in the liver-damaged mice. FT was more effective in liver-damaged mice than control. It was assumed that the suppression of 5-FU decomposition was due to the insufficient liver function. Effect of UFT was similar in liver-damaged mice to control. These data show that the effects of FT and UFT were not reduced in tumor-bearing mice by liver damage.
