Irradiation at the University of Michgan in the 1960's was carried out in 192patients with endolaryngeal carcinoma. Thirty-two and 66% of the cases were located inthe supreaglottic and glottic regions respectively. Cases were classified in stages appropiate TNM GROUPING. Results were analyzed with respect to tumor location, size, anddose-time relationship. Early lesions were controlled more often than advanced ones. Radical surgery to the primary and/or neck improved overall survival, which was 89% at 5years for 127 glottic carcinoma cases and 61% for 61 patients with supraglottic tumors. No significant complications were found following radiation therapy.
