title: Five-year survival of patients with larynx carcinoma treated with irradiation.
abstract: 182 cases of laryngeal carcinoma treated with irradiation alone or combined surgery and radiotherapy are presented. The five-year survival of the whole series was 56%. 109 (60%) of the cases had a glottic, and 73 (40%) a supraglottic tumour. Of the patients with glottic tumour 58% and of those with supraglottic tumour 53% survived five years. There was no significant difference between cases treated with conventional X-rays and cobalt therapy except in T1 cases which were treated with radiotherapy alone: of the 21 cases treated with X-rays eleven (52%), and of 29 treated with cobalt 24 (83%) survived five years.
