Abstract

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).

摘要

脊柱转移是临床实践中的日常挑战。立体定向身体放射治疗（SBRT）可以提供具有出色长期控制率的确定性治疗。其实施需要专用设备和日常图像引导放射治疗(IGRT)。XSight™脊柱跟踪系统，与Cyberknife®(Accuray™)集成，提供了脊柱SBRT的无基准跟踪系统。我们报告了由于椎体压缩性骨折（VCF）的发生而导致治疗过程中跟踪失败的罕见病例。
