Stereotactic Body Radiation Therapy for Oligometastatic Spine Disease

Abstract

30 n APPLIED RADIATION ONCOLOGY www.appliedradiationoncology.com September 2020 O disease (OMD) is an intermediate stage of cancer between an isolated tumor and widespread metastatic disease, where cancer cells from the primary tumor travel through the body/bloodstream to form a small number of clinically detectable metastatic lesions – typically less than 5 – elsewhere in the body. It is a disease state in which therapy may enable longterm disease management, much like with diabetes and heart disease, and unlike prior paradigms where metastatic disease was incurable, treatment may be potentially curative.1
