[Radiosensitivity of malignant melanoma].

Based on case histories of 67 patients with malignant melanomas (14 primary tumors and 53 metastases to the lymph nodes) who underwent sole irradiation, the correlation between the total dose needed for a local healing and the period of treatment has been investigated. It appeared that excessively high doses are not necessary for healing. A dose of about 5500 rd in 35 days is regarded as sufficient. In long-term treatment, however, the total dose has to be increased more than, for example, with squamous cell carcinoma.
