We have begun to apply arterial redistribution and preoperative embolization in superselective intra-arterial chemotherapy from the superficial temporal artery. This study examines two typical cases of upper gingival cancer. Case 1 was a male, age 61, with T4N0M0 upper gingival cancer. Drug dosage began with 50-100 mg/m 2 /day of 5-FU, while 15 mg/m 2 /hour of Docetaxel was also given once a week for three weeks. At the same time, radiation therapy with a total of 30 Gy(2 Gy at a time)was

... Immediately before the operation, embolization in the internal maxillary artery was performed in order to limit bleeding. Case 2 was a female, age 73, with T3N0M0 upper gingival cancer. This patient was also given 5-FU and Docetaxel for four weeks respectively with a total of 40 Gy radiation therapy. No operation was performed. Both cases gained CR with a sole side effect of grade 3 mucositis. Superselective intra-arterial chemotherapy with arterial redistribution in the oral area is highly effective due to local, concentrated dosage of anticancer drug and reduced side effects. It is a promising method to replace surgical operation especially in cases of upper gingival cancer, whose tumor is often limited to the internal maxillary artery alone.
