Phase II study of 10-EdAM in patients with squamous cell carcinoma of the head and neck, previously untreated with chemotherapy.

Fifteen patients with advanced head and neck cancer not curable with radiation or surgery were entered into a phase II study of 10-EdAM. None of the patients had received prior chemotherapy. 10-EdAM was administered intravenously at a dose of 80 mg/m2 each week. Four patients were not eligible for evaluation. Two died before completing four cycles of chemotherapy, one refused further treatment and one developed hepatic toxicity resulting in withdrawal. Of the remaining patients, three had a partial response. The major toxicities were leukopenia and mucositis.
