[Evolving role of radiation therapy in nonmalignant disorders].

ABSTRACT

Various nonmalignant disorders have traditionally been treated with radiation therapy. It has almost completely been discontinued due to reports of secondary malignancy. During the past 15 years there has been an evolving role for radiation therapy in various nonmalignant disorders such as meningioma, A-V malformation, prevention of vascular restenosis and heterotopic bone formation. Appropriate follow-up of such patients for diagnosis of secondary malignancy is recommended. Radiation therapy should be carefully considered in diseases not successfully treated with conventional means.
