Importance Rising cancer incidence combined with improvements in systemic and local therapies extending life expectancy are translating into more patients with spinal metastases. This makes the multidisciplinary management of spinal metastases and development of new therapies increasingly important. Spinal metastases may cause significant pain and reduced quality of life and lead to permanent neurological disability if compression of the spinal cord and/or nerve root occurs. Until recently, treatments for spinal metastases were not optimal and provided temporary local control and pain relief. Spinal stereotactic ablative radiotherapy (SABR) is an effective approach associated with an improved therapeutic ratio, with evolving clinical application. Objective To review the literature of spinal SABR for spinal metastases, discuss a multidisciplinary approach to appropriate patient selection and technical considerations, and summarize current efforts to combine spinal SABR with systemic therapies. Evidence Review The MEDLINE database was searched to identify articles reporting on spinal SABR to September 30, 2018. Articles including clinical trials, prospective and retrospective studies, systematic reviews, and consensus recommendations were selected for relevance to multidisciplinary management of spinal metastases. Results Fifty-nine unique publications with 5655 patients who underwent SABR for spinal metastases were included. Four comprehensive frameworks for patient selection were discussed. Spinal SABR was associated with 1-year local control rates of approximately 80% to 90% in the de novo setting, greater than 80% in the postoperative setting, and greater than 65% in the reirradiation setting. The most commonly discussed adverse effect was development of a vertebral compression fracture with variable rates, most commonly reported as approximately 10% to 15%. High-level data on the combination of SABR with modern therapies are still lacking. At present, 19 clinical trials are ongoing, mainly focusing on combined modality therapies, radiotherapy prescription dose, and oligometastic disease. Conclusions and Relevance These findings suggest that spinal SABR may be an effective treatment option for well-selected patients with spinal metastases, achieving high rates of local tumor control with moderate rates of adverse effects. Optimal management should include review by a multidisciplinary care team.

立体定向消融放疗治疗脊柱转移瘤:审查。

重要性癌症发病率上升,加上全身和局部疗法的改善,延长了预期寿命,正在转化为更多的脊柱转移患者。这使得脊柱转移瘤的多学科管理和新疗法的开发变得越来越重要。如果发生脊髓和/或神经根受压,脊柱转移可能会导致严重疼痛并降低生活质量,并导致永久性神经功能障碍。直到最近,脊柱转移瘤的治疗还不是最佳方法,只能提供暂时的局部控制和缓解疼痛。脊柱立体定向消融放射治疗(SABR)是一种有效的方法,可随着临床应用的不断发展提高治疗率。目的回顾脊柱SABR治疗脊柱转移的文献,讨论了适合患者选择和技术考虑的多学科方法,并总结了目前将脊柱SABR与全身疗法相结合的努力。证据审查检索MEDLINE数据库,以确定截至2018年9月30日有关脊柱SABR的报道。选择与临床研究,前瞻性和回顾性研究,系统评价和共识性推荐相关的文章,以与脊柱转移瘤的多学科管理相关。结果纳入了59篇针对5655例接受SABR脊柱转移治疗的患者的独特出版物。讨论了四个全面的患者选择框架。从头开始,脊柱SABR与一年的局部控制率相关,大约为80%至90%,术后为大于80%,并且在重新照射设置中大于65%。讨论最多的不良反应是椎体压缩性骨折的发生率发生变化,最常见的报道约为10%至15%。仍然缺乏有关SABR与现代疗法结合的高水平数据。目前,正在进行19项临床试验,主要侧重于联合疗法,放疗处方剂量和低转移性疾病。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。讨论最多的不良反应是椎体压缩性骨折的发生率发生变化,最常见的报道约为10%至15%。仍然缺乏有关SABR与现代疗法结合的高水平数据。目前,正在进行19项临床试验,主要侧重于联合疗法,放疗处方剂量和低转移性疾病。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。讨论最多的不良反应是椎体压缩性骨折的发生率发生变化,最常见的报道约为10%至15%。仍然缺乏有关SABR与现代疗法结合的高水平数据。目前,正在进行19项临床试验,主要侧重于联合疗法,放疗处方剂量和低转移性疾病。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。仍然缺乏有关SABR与现代疗法结合的高水平数据。目前,正在进行19项临床试验,主要集中在联合方式疗法,放疗处方剂量和低转移性疾病方面。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。仍然缺乏有关SABR与现代疗法结合的高水平数据。目前,正在进行19项临床试验,主要侧重于联合疗法,放疗处方剂量和低转移性疾病。结论和相关性这些发现表明,脊柱SABR对于选择良好的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。结论与相关性这些发现表明,脊柱SABR对于精选的脊柱转移瘤患者可能是一种有效的治疗选择,可以实现较高的局部肿瘤控制率和中等程度的不良反应。最佳管理应包括多学科护理团队的审查。
