[5-FU concentration in tissues of gastric cancer patients with preoperative administration of UFT--especially in comparison with FT-207].
FT-207 or UFT was administered preoperatively to 74 patients with gastric cancer. The 5-FU and FT-207 concentrations in the serum and various tissues were investigated. The 5-FU concentration in various tissues was higher than in the serum after the administration of FT-207 or UFT. Especially it showed that 5-FU concentration in tumor was highest in other normal tissues. The 5-FU concentration in the tumor for the UFT group was higher than for the FT-207 group. There was a significant difference between the UFT and FT-207 groups (P less than 0.05). Levamisole had no influence on the concentration of 5-FU.
