Résumé : Two prior surveys were carried out in 1995 and 1999 to evaluate the use of radiotherapy in the treatment of non-malignant disease. In 2016, the same questionnaire was used and sent to the 24 centers of the country: 22 responded. A major decrease was observed in the number of patients treated: 360 in 2016 in contrast to 954 in 1999 and 1113 in 1995. The most frequent indications remain the prevention of heterotopic bone formation, keloids or gynecomastia. A new indication was observed: trigeminal nevralgia treated with radiosurgery. Two frequent indications in the past disappeared: the prevention of coronary restenosis and the macular degeneration. A great agreement was observed regarding the possible indications for radiotherapy but also to avoid it for inflammatory pathologies.
