title: [T4 carcinoma of the oral cavity responsive to bilateral 5-FU intra-arterial infusion and simultaneous irradiation].
abstract: 5-FU intra-arterial infusion and simultaneous irradiation can cure head and neck cancer without leaving any functional disturbance. Catheters were inserted into the bilateral superficial temporal arteries in a case of T4 carcinoma of the oral cavity, and this treatment was performed. The patient was a 54-year-old male with squamous cell carcinoma involving the right tonsil, right and left sides of the soft palate, the uvula, right gingiva, right lingual margin, and right buccal mucous membrane. The right soft palate was partially defective. The total dose of intra-arterial 5-FU was 4,000 mg on the right side and 2,600 mg on the left side, and the total dose of irradiation was 40 Gy. After this treatment, residual cancer was found on the right margin of the uvula only. Due to the defect in the soft palate, the effect of intra-arterial infusion was considered to be insufficient for this region, and it was excised together with the surrounding tissue. Rhinolalia aperta remains, but there is no dysphagia, and the course has been good with no evidence of recurrence so far. When it is found that a catheter cannot be readily inserted, it can usually be inserted properly by using a guide wire. For fixing the catheter, a satisfactory result is obtained by cutting the protruding end to 15-20 cm, attaching a connector, and suturing it to the skin of the temporal region.
