Radiation to the carotid arteries, e.g. in the context of head and neck cancer treatment, is one of several risk factors for artery stenosis. In principle, this fact may also have implications for stereotactic cervical spine radiotherapy, because long-term survival can be achieved in patients with oligometastatic disease and favorable prognostic features. Here, we suggest that radiation dose distributions with reduced dose to the carotid artery are achievable when planning stereotactic cervical spine radiotherapy. Patients with high likelihood of long-term survival may benefit from such vessel-sparing approaches.
例如在头颈部癌症治疗中，对颈动脉进行放疗是动脉狭窄的几个危险因素之一。原则上，这一事实可能也适用于立体定向颈椎放疗，因为寡转移疾病且具有良好预后特征的患者可实现长期生存。在此，我们认为在计划立体定向颈椎放疗时，可实现减少对颈动脉剂量的放射剂量分布。具有高长期生存可能性的患者可能会从这种血管保护方法中获益。
