title: [Kilovolt-megavolt irradiation techniques for malignant tumors. Characteristics, indication and limits (author's transl)].
abstract: For curative effects of irradiation tumour doses of 5000 to 7000 rd are needed. They can be achieved in depth-therapy with conventional kilo-volt techniques only in carcinoma of the larynx and - via additional gamma rays - in radium-X-ray irradiation of the cervix. For all other indications mega-volt techniques are needed. If properly used, their side-effects are less. The kilo-volt technique for malignant tumors remains for palliative indications. Training will have to be undertaken in centres equipped for all types of therapy.
