Superselective intraarterial chemotherapy in combination with irradiation: preliminary report

Since 1984, a new method for the intraarterial administration of antineoplastic drugs, termed "superselective intraarterial chemotherapy," has been used in combination with simultaneous irradiation in the treatment of 49 patients with squamous cell carcinoma of the head and neck. Under the fluoroscope, a retrograde catheter is inserted into the superficial temporal artery and the tip is led selectively into the main feeding artery of the tumor. In our series of 49 patients, catheter-related complications occurred in only 12.5%. Forty-five patients (91.8%) completed more than 80% of the planned irradiation dosage. The therapeutic effect was excellent. The initial response rate was 100%. Systemic toxicity was uncommon, but local mucositis was frequent in the infused area. These results demonstrate that this new combined therapy is easy, safe, effective, and confers the highest possible initial response rate.
