[An occurrence of a neurogenic sarcoma in an irradiated field following the combined surgical-radiologic treatment of a childhood adenosarcoma of the kidney].

Malignant neoplasias in childhood generally are an increased risk for the patient to fall ill with a second tumor. Second tumors in former irradiation field are seldom, but are acknowledged radiogenically if histology is different to that of the first tumor and a sufficiently long period is between the two tumors. A patient is represented who had been operated and irradiated because of an adenosarcoma of the kidney at the age of seven and who has fallen ill with a neurogenic sarcoma in irradiation area more than 30 years later. The same patient had to suffer from radiogenic retardation during differentiation of lumbar apparatus of attitude and locomotion and on the other hand he became father of a healthy daughter at the age of 32.

[Application of the NSD-concept for the ascertainment of tolerance doses in the region of the lung (author's transl)].

A clinical application of the NSD-concept using iso-ret plans for the recording of radiation pneumonitis is reported. The conditions of an ascertainment of tolerance values for single organs by help of the Ellis formula are discussed. Of the examined patients with Hodgkin's disease who had been exposed to irradiation of the unaffected mediastinum, 42% suffered from radiogenic lung complications. The calculated iso-ret plans reveal a limitation of the pneumonitic shadow zone identical to the 1200-ret isoline. The data in literature are in accordance with these results.
