Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate, whether multi-fraction stereotactic body radiation therapy (SBRT) within 3 treatment fractions is non-inferior to the current standard of care of 5 fraction SBRT regarding pain response at 3 months after radiotherapy.
