Vertebral compression fracture during stereotactic body radiotherapy for spinal metastasis: A rare case of tracking failure

Cancer Radiother. 2020 Dec;24(8):866-869. doi: 10.1016/j.canrad.2020.03.016. Epub 2020 Oct 29.


Spinal metastasis are a daily challenge in clinical practice. Stereotactic body radiotherapy (SBRT) allows delivery of definitive treatment with excellent long-term control rates. Its implementation needs dedicated devices and day-to-day image-guided radiotherapy (IGRT). The XSight™ spine tracking system, integrates with the CyberKnife® (Accuray™), provides a fiducial-free tracking system for spinal SBRT. We report a rare case of tracking failure during treatment due to the occurrence of a vertebral compression fracture (VCF).
