Abstract
Introduction
In this prospective study, the efficacy and safety of radiotherapy combined with zoledronic acid was evaluated.
Materials and methods
Breast cancer patients with painful bone metastases were randomized to either high- or reduced-dose radiotherapy. All patients received zoledronic acid (4 mg) every 28 days from the beginning of radiotherapy. Analgesic and pain scores in addition to visual analog score (VAS) for treatment satisfaction and whole-body bone scintigraphy were evaluated.
Results and conclusion
No significant differences could be found in analgesic or pain scores and bone scintigraphy results between the groups. Our results suggest that reduced-dose radiotherapy produces similar response rates and response durations when used concomitantly with zoledronic acid.
