[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.
