Abstract Background: Vinorelbine is an active drug in the treatment of lung and breast cancers and has a favorable toxicity profile. Many clinical trials have demonstrated its antitumor activity in other tumor types including squamous cell carcinoma of the head and neck (SCCHN). We investigated the efficacy and tolerability of vinorelbine in patients with recurrent and/or metastatic SCCHN, previously untreated by chemotherapy. Patients and methods: Seventy-one patients with locoregional recurrent and/or metastatic SCCHN were treated with vinorelbine at a dose of 30 mg/m2/week i.v. by short-duration infusion on an out-patient basis. Doses were adjusted according to tolerance. Results: Two complete and seven partial responses were observed among 56 evaluable patients, yielding a response rate of 16% (95% confidence interval (CI): 8%–28%). The overall response rate of all eligible patients (63) was 14%. The responses were seen in recurrent tumors, lymph nodes and in lung metastases, and their median duration was 19 weeks (12–63). The main toxicity, severe and reversible neutropenia (grade 3–4) occurred in 53% of the 69 evaluable (for toxicity) patients. Twelve patients developed severe bronchopulmonary infections, which caused two early deaths. Constipation was observed in 31 patients (45%). Other gastrointestinal toxicities, asthenia, acute pain syndrome and peripheral sensory neuropathy, were mild to moderate. The median number of treatments was seven cycles and the median relative dose intensity of vinorelbine was 85% (25.5 mg/m2/week). Conclusions: Vinorelbine is an active drug, with acceptable toxicity, in recurrent and/or metastatic SCCHN, at the dose and schedule administered in the present study. Further evaluation in association with other agents and/or radiotherapy is warranted.
