[Experiences with sole radiation therapy of primary osteogenic sarcomas (author's transl)].

In the course of the previous six years, nine osteogenic and three juxtacortical sarcomas have been irradiated for the single purpose of local tumor sanitation and final cure of the patient. Of nine cases with osteosarcomas, six are still alive. Two are surviving without recurrences these five years, three without metastasition. The 3-year survival amounts to 3/5. Radiation effects from high-dosage treatment are remarkably small. The cure rate after radiation therapy seems not to be inferior to the results after surgery.
