Stereotactic body radiotherapy

Stereotactic body radiotherapy delivers high dose per fraction radiation to the entire volume of the tumor.

Surrounding organs should be identified and can subsequently be spared from high dose radiation.

SBRT overcomes radio resistance in most tumors and delivers ablative doses of radiation.

SBRT can be associated with fracture progression, due to bone necrosis. Therefore, Pre-SBRT stabilization should be considered if the following factors are observed:

• Baseline vertebral compression fracture
• SINS score 7-12
• Planned SBRT with ≥20 Gy per fraction
