Abstract
Radiation therapy is generally considered to be the best primary treatment for early glottic carcinoma, with surgery reserved for local failure. In a series of 150 cases of T1 glottic carcinoma 138 were given radiation alone. In these patients the survival was 88 per cent at 3 years and 77 per cent at 5 years. Local control remained unchanged at 82 per cent after 6 years. When the results of surgery are included, local control was raised to 93 per cent. Preservation of the larynx was obtained in 92 per cent of survivors. Local extension or radiation dose levels had no influence on local control. The optimum dose could be lower than generally recommended. Voice quality after radiation therapy is superior to postsurgical laryngeal function. Since survival rates are identical, radiation therapy alone is the treatment of choice in all early glottic carcinomas.
