Thirty-six patients with carcinoma of the tonsillar region treated with radical radiotherapy at Yonsei Cancer Center between Jan. 1971 and Dec. 1980 were retrospectively reviewed. The purpose of this study is to evaluate the clinical characteristics and the treatment results. Seventy-five per cent of patients were in advanced stage when they were first seen. Incidence of nodal involvement at the time of initial presentation was $64\%$. Bilateral nodal involvement was found in $19\%$ of cases. Three-year local control rates for T1, T2, T3, and T4 were $88\%,\;46\%,\;25\%,\;and\;11\%$, respectively. Advanced neck nodes were poorly controlled $(N1\;70\%,\;N2\;20\%,\;N3\;12\%)$. The prognosis is mainly affected by the status of the primary and neck nodes Overall three-year local control rate was $42\%$.
