Cancer of the tonsil: results of radical radiation therapy with surgery in reserve

American Journal of Surgery
P G GarrettW D Rider

Abstract

Three hundred seventy-two patients with squamous cell carcinoma of the tonsil were treated with primary irradiation of curative intent. Surgery was saved for subsequent treatment failure. The overall survival was 38 percent at 5 years. Local control was 63 percent for all patients. T1 and T2 lesions were controlled in 87 percent and 68 percent of patients, respectively, and T3 lesions were controlled in 50 percent of patients. Patients with healthy (N0) nodes and those with mobile nodes had a high degree of regional control, but fixed nodes were controlled in only 37 percent of patients with radiation alone. The most common site of treatment failure was in the primary tumor, which accounted for 45 percent of relapses, and isolated nodal relapses were present in only 24 percent of patients. Subsequent surgery was possible in 47 percent of patients in whom initial treatment failed. A higher degree of subsequent control was obtained with more aggressive surgery compared with simple local resection. There was a high rate of second respiratory tract malignancy, in fact, after 2 years, patients were dying more commonly of their second respiratory tract malignancies than of cancer of the tonsil.
