RTAD-05 LOCAL RECURRENCE AND RADIONECROSIS WITH 3-FRACTION STEREOTACTIC RADIOTHERAPY FOR POSTOPERATIVE CAVITIES AND INTACT BRAIN METASTASES: A PROSPECTIVE REGISTRY STUDY
Abstract Objective Stereotactic radiotherapy has been increasingly used for brain metastases though differences between single fraction and hypofractionated regimens remain incompletely defined. We performed a lesion-level competing-risk analysis to evaluate cumulative incidence of radiation necrosis (RN) and local rec...
