[Radiotherapy for non-tumoral disorders : a brief history and indications in 2024].

Abstract

Radiotherapy for non-tumoral disorders has a long history. Lack of high-level evidence, therapeutic alternatives and fear of side effects (particularly radiation-induced cancer) reduced some indications to a trickle during the second half of the 20th century. Others were logically abandoned. There are two exceptions to this trend. On the one hand, some Central European countries (Germany in particular) still use radiotherapy regularly for diseases such as osteoarthritis, plantar fasciitis, chronic tendinopathies, Dupuytren's disease, etc. On the other hand, the development of stereotactic ablative radiotherapy has opened up new indications, whether cerebral (arteriovenous malformations, trigeminal neuralgia, obsessive-compulsive disorders) or cardiac (ventricular tachycardia). In this article, we present a non-exhaustive list of some indications (or rather possibilities) for radiotherapy in non-tumoral disorders in 2024.
