The treatment of glottic carcinoma: an analysis of 800 cases.

All patients with cancer of the glottis seen at the Ontario Cancer Institute from 1955 to 1971 are reviewed. Changes in referral patterns and treatment policy are noted. Particular attention is given to those patients who received radiation for cure, and the place of laryngectomy in their subsequent management is examined. Of the estimated incidence of the disease in the geographic region served, 95 percent are now being seen and of these 97 percent receive treatment with curative intent. Two-thirds or 67 percent are cured at five years and their larynges intact, while a further 18 percent are cured by subsequent laryngectomy.
