Abstract Background Treatments for cancer spinal metastasis were always palliative. This study was conducted to investigate the safety and effectiveness of IG-IMRT for these patients. Methods 10 metastatic lesions were treated with conventionally-fractionated IG-IMRT. Daily kilovoltage cone-beam computed tomography kV-CBCT scan was applied to ensure accurate positioning. Plans were evaluated by the dose-volume histogram DVH analysis. Results Before set-up correction the positioning errors in the
