From March of 1979 through December of 1982, 84 Patients with supraglottic carcinoma were seen and evaluated in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 68 patients were treated with a curative intent by employing either radiotherapy alone or a combined approach of radiotherapy Plus surgery. Sixteen patients refused to complete the treatment program. Seventy-three per cent of patients had $T_3;and;T_4$ lesions and $63\%$ of patients had lymph node metastasis at the time of diagnosis. Actuarial recurrence-free survival at 3 year was: Stage $I~II;62;%,;Stage;III ;54\%,;Stage;IV;18\%$, For $T_{1-2},;T_3;and;T_4$ lesions, the actuarial recurrence free survival at 3 years were 50\%,;34;%;and ;9\%$ respectively. Of 39 Patients with treatment failure, 29 Patients $(78\%)$ had uncontrol or ultimate recurrence at the primary site while 9 patients having lymph node recurrence, 14 patients$(21\%)$ had lymph node recurrence, and S patients had distant metastasis. It is suggested that planned combined radiotherapy is indicated for advanced but rescetable supraglottic carcinoma.
