Abstract
Summary Thirty-two patients with squamous cell carcinoma of head and neck not amenable to surgery or radiotherapy were treated with a combination of methotrexate 0.6 mg/kg IV weekly, bleomycin 15 mg IV weekly, and hydroxyurea 1,000 mg/m2 three oral doses weekly. Eleven complete responses and ten partial responses of more than 50% were observed. The mean duration was 43 weeks for complete responses and 35 weeks for partial responses. Toxicity consisted in leukopenia, thrombocytopenia, nausea, vomiting, stomatitis, and cutaneous alterations. Only one patient suffered reversible lung toxicity. These results suggest that a combination of three drugs in squamous cell head and neck cancer may be more effective than a combination of bleomycin and methotrexate only.
