Summary
Extracranial stereotactic body radiotherapy (SBRT) precisely delivers high radiation doses to tumors outside the brain. This advanced technique improves tumor control rates, rivaling surgical outcomes for various cancers.
Area of Science:
- Radiation Oncology
- Medical Physics
Background:
- Extracranial stereotactic body radiotherapy (SBRT) has evolved over 25 years.
- It enables precise delivery of ablative doses of hypofractionated radiotherapy to extracranial targets.
Purpose of the Study:
- To provide an overview of SBRT.
- To review the evidence supporting SBRT for common cancer sites.
Main Methods:
- Review of prospective Phase I and II studies.
- Evaluation of SBRT in non-small cell lung cancer, liver tumors, and spinal metastases.
Main Results:
- SBRT allows for intensified radiation dose and fractionation.
- Tumor control rates achieved with SBRT approach those of surgical resection.
Conclusions:
- SBRT is a refined therapeutic approach in radiation oncology.
- Evidence supports SBRT's efficacy in treating various extracranial malignancies.
