Abstract

To evaluate the pain response, local tumor control and toxicity of stereotactic body radiotherapy (SBRT) with helical tomotherapy (HT) in the patients with spine metastasis. From May 2009 to June 2010, 22 patients with 31 lesions were treated by SBRT. Dose scheme were 24 Gy in 3 fractions (87.1%), 30 Gy in 5 fractions (9.7%), and 16 Gy in a single fraction (3.2%). Pain was assessed using a numerical rating scale. Analgesic consumption was recalculated into the daily oral morphine-equivalent dose (OMED). The response criteria of International Bone Metastases Consensus Group (IBMCG) was used. The median follow-up duration was 10 months (range 3-23 months). After SBRT the mean pain score decreased significantly (4.32 before SBRT, 0.71 at 3 months). However, median OMED didn't decrease until 3 months after SBRT (Median OMED; 34.5 mg before SBRT, 45 mg at 3  months). Pain response rate and pain progression-free survival rate at 3 month was 96.8  and 93.5%, respectively. Local progression-free survival rate at 3 month was 93.5%. There was no severe acute toxicity. SBRT with HT is a safe and effective treatment modality for local tumor control and pain palliation associated with spine metastasis.
