The individual risk of symptomatic radionecrosis after brain metastasis radiosurgery is predicted by a continuous function of the V12Gy☆

Abstract

Highlights • Symptomatic radionecrosis risk after brain metastases SRS is predicted by the V12Gy.• A history of whole-brain radiotherapy did not increase the risk.• Location, DS-GPA, previous surgery or vascular disease were not predictors.
