title: [Pharmacological and pharmacodynamic aspects of cancer chemotherapy, with special reference to 5-fluorouracil and its derivatives].
abstract: 5-FU analogs being investigated in Japan are; 5-FU, FT, FD-1, HCFU, UFT, TAC-278, 5'-DFUR, FF-705, and TK-117. They exert antitumor activity via 5-FU which is an intermediate metabolite of those derivatives. In this paper, UFT, TAC-278, and 5'-DFUR, were particularly investigated from the point of view of pharmacokinetics of those drugs (or 5-FU) in the blood, normal and tumor tissues of patients with gastric cancer. As a result, it is concluded that observation of the sequential changes of 5-FU level in various tissues of humans is potential in designing cancer chemotherapy.
