Summary description of the study

Comparison of two irradiation schemes for the treatment of bone metastases outside the spine

(BASEC)

Intervention under investigation

We want to investigate in this study whether high-precision radiotherapy over 3 sessions with 9 Gy per session within one week is as effective as high-precision radiotherapy over 5 sessions with 7 Gy per session within one week.
