Abstract: |
This chapter provides an overview of spinal stereotactic body radiation therapy (SBRT), a highly advanced and precise form of radiation therapy used in the management of spine tumors. It begins with an introduction to the concept of SBRT and its application in treating spinal tumors, emphasizing its ability to deliver high doses of radiation with minimal toxicity to surrounding tissues. The chapter then highlights the neurologic, oncologic, mechanical, and systemic (NOMS) framework, which is integral in treatment planning, involving a multidisciplinary approach with various medical specialties. It further discusses the importance of imaging, particularly MRI, in identifying spine metastases and guiding treatment. The process of simulation for treatment planning, including the use of CT simulation and the importance of visualizing the spinal cord, is carefully described. The chapter then details the contouring process for both definitive and postoperative cases, explaining the delineation of target volumes and the consideration of anatomical structures. Dose fractionation strategies are discussed, highlighting different protocols for various patient conditions and tumor characteristics. The chapter also covers planning and treatment delivery, emphasizing the importance of balancing target coverage with the protection of organs at risk. Finally, it addresses on-treatment management and follow-up care, noting potential side effects and complications, and the importance of monitoring and supportive care post-treatment. The chapter is supplemented with figures and tables that provide visual and data-driven insights into the various aspects of spinal SBRT. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2025. |
