title: [Radiotherapy of precancerous conditions in the ENT area].
abstract: Precancerous lesions of the oral cavity and the larynx are usually treated by surgery, because a complete histological examination for detecting an invasive carcinoma is important and, on the other hand, modern surgery procedures yield very satisfactory functional results. High-dose irradiation of inoperable high-risk precancerous lesions of the larynx may be taken into account. Experiences in the irradiation of inoperable low-risk lesions with different doses are very rare. The carcinoma in situ should be treated like an invasive carcinoma. 10 years of experience in radiotherapy of precancerous lesions of the larynx in 23 patients are reported.
