What is Stereotactic Body Radiation Therapy for Nonspine Bone Metastases: International Practice Patterns to Guide Treatment Planning about?

## Purpose: Stereotactic body radiation therapy (sbrt) is increasingly used for nonspine bone metastases (nsbm); however, there are limited data informing treatment planning. we surveyed international experts to better understand worldwide practice patterns in delivering nsbm-sbrt. ## Methods and materials: Nine international radiation oncologists were invited to participate based on demonstrated expertise with nsbm-sbrt. experts were sent gross tumor volume contours and planning computed tomography and magnetic resonance images for 11 nsbm cases that covered a range of bony sites, including metastases to long bones (femur, humerus), pelvic bones (ilium, ischium, acetabulum, pubic symphysis), and thoracic bones (rib, sternum, scapula, clavicle). experts were surveyed regarding treatment planning decisions and dose-fractionation selection. descriptive analysis was conducted on the survey data. ## Results: All experts participated and completed the survey. most (56%) routinely fused magnetic resonance imaging with planning computed tomography imaging for target delineation. dose fractionation schedules included single-fraction (18-24 gy/1), 2 fractions (24 gy/2), 3 fractions (28-30 g
