title: [Ionising rays and laryngeal carcinomas (author's transl)].
abstract: Review of the literature and report of a new care of laryngeal cancer after irradiation of a benign lesion of the neck. These cases obviously become rare since benign lesions are no longer irradiated. Today the risk of inducing a second carcinoma by a successful irradiation of the first tumor becomes more important. A study of 109 patients, irradiated for laryngeal carcinoma and surviving with no evidence of disease for a period of at least 5 years has been performed. 8 of these patients developed a second primary in the previously irradiated area after 7-15 years. These second carcinomas are not rare if one considers that most patients with laryngeal carcinoma are 60-70 years old and therefore the life expectance on an average is low. These facts should be taken into consideration when deciding between surgical or radiation therapy in younger patients with high life expectance.
