In Korea, carcinoma of the larynx constitutes approximately 2.3% of all malignancies among males and about 500 new patients occur in a year. It is well known that survival rate of laryngeal cancer is rather higher than any other head and neck malignancies. Authors are reporting the treatment result of 170 laryngeal cancers who were treated at Seoul National University Hospital since 1979. All 170 patients received curative therapy and analyzed by life table method. 3-year NED survival rates were estimated according to the stage, anatomical site and mode of treatment. All hypopharyngeal cancers were excluded. Results are as follows ; 1) Overall 3-year NED survival rate was 64%, and showed Stage I 91%, Stage II 77%, Stage III 67%, Stage IV 57%. 2) Glottic cancer showed much better prognosis(3-year NED 80%) than supraglottic cancer(3-year NED 53%). 3) 3-year NED survival rate according to treatment modality was 90% in surgery only group, 74% in surgery with postoperative radiation group, 45% in radiation only group, and 67% in salvage surgery group. 4) 3-year NED survival rate in patients with total laryngectomy was 77%.
