Combined radiation-methotrexate therapy in preoperative management of carcinoma of the head and neck.

Fifty patients with primary carcinoma of the head and neck were treated preoperatively with 2,000 r and 500 mg/m2 of methotrexate. This combination reduces the tumor size in more than 90 per cent of patients, converts many of the tumors to a more manageable state, and appears to indicate that improved survival will occur.
