Combination chemotherapy with vincristine, bleomycin, and methotrexate for advanced head and neck cancers

Abstract

Thirty-three patients with a histologically confirmed diagnosis of advanced squamous cell carcinoma of the head and neck were treated with a combination of vincristine, methotrexate, and bleomycin. The regimen was as follows: Day 1, vincristine (2 mg iv) and methotrexate (200 mg/m2 iv over 24 hours); Day 2, bleomycin (15 mg/day by iv infusion for 48 hours). Folinic acid rescue began 36 hours after the start of methotrexate. The regimen was repeated at intervals of 3 weeks. Toxicity was minimal but the overall response rate was only 24% (three complete responses and five partial responses) and the median duration of remission was only 16 weeks overall. The combination of vincristine, methotrexate, and bleomycin in this dosage schedule has a response rate lower than that reported with single-agent treatment of advanced head and neck cancers.
