Brain stereotactic radiosurgery (SRS) and spine stereotactic body radiation therapy (SBRT) are commonly treated by a multidisciplinary team of neurosurgeons, radiation oncologists, and medical physicists. However the treatment objectives, constraints, and technical considerations involved can be quite different between the two techniques. In this interactive session an expert panel of speakers will present clinical brain SRS and spine SBRT cases in order to demonstrate real-world considerations for ensuring safe and accurate treatment delivery and to highlight the significant differences in approach for each treatment site. The session will include discussion of topic such as clinical indications, immobilization, target definition, normal tissue tolerance limits, and beam arrangements.
- 1.Understand the differences in indications and dose/fractionation strategies for intracranial SRS and spine SBRT.
- 2.Describe the different treatment modalities which can be used to deliver intracranial SRS and spine SBRT.
- 3.Cite the major differences in treatment setup and delivery principles between intracranial and spine treatments.
- 4.Identify key critical structures and clinical dosimetric tolerance levels for spine SBRT and intracranial SRS.
- 5.Understand areas of ongoing work to standardize intracranial SRS and spine SBRT procedures.
