The Importance of Radiation Planning Guidelines in Spinal Stereotactic Body Radiotherapy.

Abstract

Introduction: Stereotactic body radiotherapy (SBRT) is a well-established treatment for spinal metastases. Official guidelines for radiation planning were published and revised by several groups. Here, we present real-world data about the importance of adhering to those guidelines.

Case report: A 42-year-old metastatic colon cancer patient presented with oligometastatic disease to L3 vertebra and underwent SBRT treatment. Due to lack of adhering to official guidelines both in dose regiment and in volume definition, he progressed locally and required re-treatment.

Conclusions: SBRT is a well-known established choice for oligometastatic spinal lesions. Thorough evaluation of imaging and adherence to clinical guidelines are crucial for achieving a high local control rate and reducing the likelihood of re-irradiation and associated complications.
