Phase II study of etoposide (VP-16) in the treatment of advanced head and neck cancer.

Eighteen patients with advanced and heavily pretreated squamous cell carcinoma of the head and neck were treated with etoposide (VP-16). Of 16 patients evaluable for response, two (13%) achieved partial response lasting 3 to 4 months, and five (31%) achieved stable disease status lasting 2 to 7 months. One patient achieved a partial response in regional lymph nodes and the primary site, while a second patient achieved a partial response of a regional lymph node recurrence. Toxicity was significant but acceptable, consisting mainly of leukopenia and alopecia. Thrombocytopenia and mild nausea were also seen. VP-16 demonstrated modest activity in this disease and might be considered for further trials.
