Preoperative irradiation for squamous cell carcinoma of the head and neck. Does it improve five year survival or control figures?
1. A well defined group of patients have been studied. 2. Composite operation resulted in a 56 per cent five year disease-free survival rate. 3. Treatment of recurrent disease with irradiation increased the five year survival to 61 per cent. 4. Preoperative irradiation for squamous cell carcinoma of the intraoral cavity, stage III, is unwarranted unless this treatment plan can produce five year end results better than 61 per cent.
