ABSTRACT
Background:
Treatment of spine bone metastases with stereotactic radio-therapy (SBRT) may produce greater pain relief than palliative radiotherapy.Aim:
To evaluate the analgesic response to SBRT. Material andMethods:
A search was made in an electronic database of all patients treated by SBRT in our center. We found 20 patients that were treated with SBRT in the spine on 24 sites (lesions). Analgesic response was evaluated at 3 and 6 months after SBRT. Other factors such as age, sex, functional status, diagnosis, metastasis location, dosimetry and toxicity of the treatment were also described.Results:
The median follow-up was 8.1 months. Complete pain relief occurred at three months in 74% of the treated sites. At three months, 78% of the patients presented a functional status 0 (ECOG). The median dose used was 24 Gy in 2 fractions. No cases of G3 or greater toxicity were recorded.Conclusions:
The analgesic response to SBRT seems to be better than that reported for palliative radiotherapy.
