Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

SBRT with 9 Gy x 3 fractions to the treatment site.

SBRT with 7 Gy x 5 fractions to the treatment site

Arm Description

Patients will be treated with SBRT delivering 9 Gy x 3 fractions (BED10: 51.3 Gy) to the treatment site.

Patients will be treated with SBRT delivering 7 Gy x 5 fractions (BED10: 59.5 Gy) to the treatment site.

Outcomes

Primary Outcome Measures

Pain relief (response rate) measured with the Visual Analog Scale (VAS) from Baseline to 3 months after treatment.
The Visual Analog Scale is a validated, subjective measure for pain. Possible scores ranges between zero (no pain) and ten (worst possible pain). The primary endpoint was defined as pain relief > 2 points from Baseline to 3 months after treatment.
