Preoperative irradiation for head and neck cancer: results of a prospective study.

Two hundred forty-eight patients with primary epidermoid carcinoma of the oral cavity, oropharynx, and hypopharynx, stages II, III, and IV were entered into a prospective randomized clinical trial of preoperative irradiation therapy (700 rads X 2) and surgery versus surgery alone. At 5 years both groups had a similar survival when analyzed according to stage of disease, primary site, or lymph node status. However, the group of patients receiving preoperative irradiation showed a lower incidence of local recurrence (22% versus 36%) preoperative irradiation showed a lower incidence of local recurrence (22% versus 36%) (P = 0.02). From this study we conclude that preoperative irradiation in this dose schedule has little influence on the ultimate outcome after surgical treatment of head and neck cancer.
