    Abstract:
    PURPOSE: To evaluate the efficacy of radiation therapy (RT) for symptomatic vertebral hemangioma (SVH). MATERIAL AND METHODS: Based on the Registry for Rare Benign Disorders (RRBD) of the German Cooperative Group on Radiation Therapy for Benign Diseases (GCG-BD), the clinical information, treatment plans and outcome data from seven cooperating German RT institutions were analyzed retrospectively. RESULTS: Over a period of 39 years (1969-2008), a total of 84 patients with 96 symptomatic lesions underwent RT. The predominant indication was pain in 97.6%, and, in addition, 28.6% of patients had neurological deficits. The median total dose was 34 Gy (4.5-45 Gy), and the median single dose 2.0 Gy (0.5-3.0 Gy). After a median follow-up of 68 months (6-422 months), complete symptom relief (CR) occurred in 61.9% of patients, 28.6% had partial relief, and 9.5% had no relief (NR). The overall response rate (CR + PR) was 90.5%. In 26.2% of patients, radiologic signs of remineralization were noted. After a median follow-up of 70 months (8-124 months), symptom progression occurred in eight patients (9.5%). Therefore, the long-term rate of local control was 80.9%. Multivariate statistical analysis revealed a significantly higher rate of symptom relief and local control for total doses > or = 34 Gy. Side effects > RTOG/EORTC grade 2 were not observed. CONCLUSION: RT is a safe and effective for treatment of SVH. Total doses of at least 34 Gy are recommended to achieve optimal treatment response.
