Abstract

Treatment paradigms for patients with spine metastases have evolved significantly over the past decade. Incorporating stereotactic radiosurgery into these paradigms has been particularly transformative, offering precise delivery of tumoricidal radiation doses with sparing of adjacent tissues. Evidence supports the safety and efficacy of radiosurgery as it currently offers durable local tumor control with low complication rates even for tumors previously considered radioresistant to conventional radiation. The role for surgical intervention remains consistent, but a trend has been observed toward less aggressive, often minimally invasive, techniques. Using modern technologies and improved instrumentation, surgical outcomes continue to improve with reduced morbidity. Additionally, targeted agents such as biologics and checkpoint inhibitors have revolutionized cancer care, improving both local control and patient survivals. These advances have brought forth a need for new prognostication tools and a more critical review of long-term outcomes. The complex nature of current treatment schemes necessitates a multidisciplinary approach including surgeons, medical oncologists, radiation oncologists, interventionalists, and pain specialists. This review recapitulates the current state-of-the-art, evidence-based data on the treatment of spinal metastases, integrating these data into a decision framework, NOMS, which integrates the 4 sentinel decision points in metastatic spine tumors: Neurologic, Oncologic, Mechanical stability, and Systemic disease and medical co-morbidities.

摘要

过去十年中,脊柱转移瘤患者的治疗模式发生了重大变化。将立体定向放射外科纳入这些模式尤其具有变革性,它能够精确地提供肿瘤杀伤剂量,同时保护相邻组织。目前,放射外科的安全性和有效性得到了证据支持,即使是对于以前被认为对常规放疗有抗性的肿瘤,它也能提供持久的局部肿瘤控制和低并发症率。手术干预的作用仍然一致,但人们观察到一种倾向,即采用侵袭性较小、通常为微创的技术。通过使用现代技术和改进的仪器,手术结果继续改善,同时发病率降低。此外,靶向药物,如生物制剂和检查点抑制剂,彻底改变了癌症治疗方式,提高了局部控制和患者生存率。这些进展带来了对新预后工具的需求和对长期结果的更严格审查。目前治疗方案的复杂性需要多学科方法,包括外科医生、肿瘤内科医生、放射肿瘤学家、介入治疗师和疼痛专家。这篇综述回顾了当前治疗脊柱转移瘤的最新技术和循证数据,并将这些数据整合到一个决策框架中,即 NOMS,该框架整合了转移性脊柱肿瘤的 4 个关键决策点:神经功能、肿瘤学、机械稳定性和全身性疾病及合并症。
