Radical Radiotherapy Results of Supraglottic Carcinoma

A total of eighty five cases with supraglottic carcinoma treated by radical radiotherapy in Yonsei Cancer Center between Jan. 1974 and Dec. 1980, was observed through retrospective analysis. This study is concerned with patients selection for irradiation alone or com bined treatment with surgery. Emphasis is directed to the analysis of effective ness of radical radiotherapy instead of partial laryngectomy in T - 1. T - 2 and early T - 3 lesion. A satisfactory control of laryngeal disease and preservation of a normal voice ranging from 100% for T1 N0 lesions, 61.1 % for T2 N0 to 50% for T3N0. But 47.1% of cases with node metastasis on admission had poor results to irradiation suggesting of necessicity of combined treatment. 5 year recurrence - free survivals was 43.3% in all cases with supraglottic carcinoma treated by irradiation alone, although it was 87'5% in T - 1 and 51.8% in T - 2.
