Single‐fraction radiotherapy versus multifraction radiotherapy for palliation of painful vertebral bone metastases—Equivalent efficacy, less toxicity, more convenient

The Radiation Therapy Oncology Group (RTOG) trial 97‐14 revealed no difference between radiation delivered for painful bone metastases at a dose of 8 gray (Gy) in 1 fraction (single‐fraction radiotherapy [SFRT]) and 30 Gy in 10 fractions (multifraction radiotherapy [MFRT]) in pain relief or narcotic use 3 months after randomization. SFRT for painful vertebral bone metastases (PVBM) has not been well accepted, possibly because of concerns about efficacy and toxicity. In the current study, the authors evaluated the subset of patients that was treated specifically for patients with PVBM.
