Southwest Oncology Group study of Mitoxantrone for treatment of patients with advanced squamous cell carcinoma of the head and neck.

Twenty-two patients are evaluable for response in a Phase II trial of Mitoxantrone for advanced squamous cell carcinoma of the head and neck. One patient had a partial response, one an improvement and twenty had progressive disease. The major toxicities were leukopenia and thrombocytopenia. There was no significant antitumor activity of Mitoxantrone in this group of patients with head and neck cancer, most of whom were previously treated with radiation and chemotherapy.
