Radiotherapy of skin tumors.

Abstract

The incidence of cancers of the skin is increasing, as is life expectancy among most of the population. Besides surgery, all skin cancers can be treated with radiotherapy, with excellent results. Unfortunately, both less training and less equipment are available than earlier, which means that dermatologists also have less experience in this field. We would like to propose radiotherapy for medium-sized or larger lesions, especially on the face in elderly people. Good indications are keratoacanthomas, extensive actinic keratoses, Bowen's disease including erythroplasia of Queyrat, basal cell and squamous cell carcinomas, but also lentigo maligna and lentigo maligna melanomas. These tumors can be treated in a curative way. Excellent results of palliative X-ray therapy are achieved in Kaposi's sarcoma and in lymphomas, and also in Merkel cell tumors. After 100 years of treatment of skin cancers by radiotherapy, dermatologists should not forget that if appropriate principles are followed and precautions are taken, X-ray treatment is still a safe and effective method.
