RTHP-12. NATIONWIDE DISTRIBUTION OF LINEAR ACCELERATOR VERSUS GAMMA KNIFE STEREOTACTIC RADIOSURGERY UTILIZATION FOR METASTATIC BRAIN DISEASE IN ACADEMIC VERSUS COMMUNITY HOSPITALS

摘要

Single-fraction stereotactic radiosurgery (SRS) is often the preferred treatment modality for metastatic brain disease, particularly when patients have a small enough volume of disease to preclude whole brain radiation therapy and its associated permanent cognitive morbidity. The two predominant SRS treatment modalities are Gamma Knife and linear accelerator (LINAC). The recent impact of SRS modality in academic versus community hospital settings in the United States (US) since the 2013 implementation of the American Tax Payer Relief Act (ATRA) has yet to be examined.
