[Clinical phase I trial of S-1 in the combination with DOC using super-selective intra-arterial infusion with oral cancer].

The super-selective intra-arterial infusion, which has high anti-tumor effect to infuse high concentration of drugs into arterial in the control of tumor, has been expected to have local control. S-1, developed by the scientific theory of both potentiating antitumor activity of 5-fluorouracil(5-FU)and reducing gastrointestinal toxicity induced by 5-FU, is an active agent for squamous cell carcinoma of the head and neck(HNSCC). Docetaxel(DOC)is the drug Taxanes which has anti-tumor effect by mechanism different from conventional anti-tumor mechanism of action. In Yamaguchi University, DOC+CDDP+5-FU in the three-drug combination therapy shows high anti-tumor effect for advanced oral cancer. In the present study, we conducted a phase I study to examine local control of S-1 in the combination with DOC using super-selective intra-arterial infusion with oral cancer. The study performed super-selective intra-arterial infusion of DOC on the first day, and was considered as the schedule which prescribes three-week S-1 for patients every day from same day. Since blood toxicity nature grade 4 discovered the result in S-1: 65 mg/m(2)day and DOC: 50 mg/ m(2), we decided that recommended dose(RD)was S-1: 65 mg/m(2) and DOC: 40 mg/m(2).
