Thirty-five consecutive patients with primary unresectable head and neck cancers were considered eligible for protocol treatment with neoadjuvant intraarterial cisplatin. External carotid artery catheterizations were technically feasible in 29 patients (83%). Twenty-five patients with 28 primary tumors received intraarterial cisplatin, 100 mg/m2, every seven to 14 days for three cycles. The most common toxicity was nausea and vomiting. Ipsilateral hemialopecia, transient VII nerve palsy, and blurring of vision seem to be unique to this route of administration at this dose. A complete response was seen at the primary tumor site in nine of 28 (32%), with 14 of 28 partial responses (50%). In evaluating both primary tumor and nodal disease, five of 25 patients achieved a complete response and 15 of 25 a partial response. In previous reports, one complete response was observed in 74 patients with head and neck cancer treated with neoadjuvant intravenous (IV) cisplatin every 3 weeks. The overall response of 82% reported here is comparable to that reported with combination chemotherapy and suggests an advantage to the arterial administration of cisplatin when possible in the neoadjuvant setting.
