Compared with conventional radiotherapy, SBRT enables delivery of a higher biologically effective dose while maintaining high precision.\n\nThe Institute of Oncology Ljubljana initiated spinal SBRT treatments in 2017 and introduced an institutional SBRT spine protocol in 2019. As SBRT is technically demanding, strict adherence to standardized planning and delivery procedures is essential to ensure treatment quality and patient safety.\n\nThis clinical program aims to support structured implementation and continuous development of the institutional SBRT spine protocol in routine clinical practice.
