[Kilovolt-megavolt irradiation techniques for malignant tumors. Characteristics, indication and limits (author's...

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.
