OBJECTIVE The aim of this study was to identify and discuss operative nuances utilizing image guidance in the surgical management of aggressive sacral tumors. METHODS The authors report on their single-institution, multi-surgeon, retrospective case series involving patients with pathology-proven aggressive sacral tumors treated between 2009 and 2016. They also reviewed the literature to identify articles related to aggressive sacral tumors, their diagnosis, and their surgical treatment and discuss the results together with their own experience. Information, including background, imaging, treatment, and surgical pearls, is organized by tumor type. RESULTS Review of the institutional records identified 6 patients with sacral tumors who underwent surgery between 2009 and 2016. All 6 patients were treated with image-guided surgery using cone-beam CT technology (O-arm). The surgical technique used is described in detail, and 2 illustrative cases are presented. From the literature, the authors compiled information about chordomas, chondrosarcomas, giant cell tumors, and osteosarcomas and organized it by tumor type, providing a detailed discussion of background, imaging, and treatment as well as surgical pearls for each tumor type. CONCLUSIONS Aggressive sacral tumors can be an extremely difficult challenge for both the patient and the treating physician. The selected surgical intervention varies depending on the type of tumor, size, and location. Surgery can have profound risks including neural compression, lumbopelvic instability, and suboptimal oncological resection. Focusing on the operative nuances for each type can help prevent many of these complications. Anecdotal evidence is provided that utilization of image-guided surgery to aid in tumor resection at our institution has helped reduce blood loss and the local recurrence rate while preserving function in both malignant and aggressive benign tumors affecting the sacrum.
目的 本研究旨在识别并讨论在侵袭性骶骨肿瘤手术治疗中利用影像引导的手术细微差别。方法 作者报告了他们在单一机构开展的、由多位外科医生参与的回顾性病例系列,该系列涉及2009年至2016年间经病理证实患有侵袭性骶骨肿瘤的患者。他们还查阅了文献,以识别与侵袭性骶骨肿瘤、其诊断及手术治疗相关的文章,并结合自身经验讨论结果。包括背景、影像学、治疗及手术要点等信息按肿瘤类型进行整理。结果 回顾机构记录发现,2009年至2016年间有6例骶骨肿瘤患者接受了手术。所有6例患者均采用锥形束CT技术(O型臂)进行影像引导手术。详细描述了所使用的手术技术,并展示了2个示例病例。作者从文献中收集了有关脊索瘤、软骨肉瘤、巨细胞瘤和骨肉瘤的信息,并按肿瘤类型进行整理,针对每种肿瘤类型详细讨论了背景、影像学、治疗以及手术要点。结论 侵袭性骶骨肿瘤对患者和治疗医生而言都是极具挑战性的难题。所选的手术干预方式因肿瘤类型、大小和位置而异。手术可能会带来包括神经受压、腰骶部不稳定和肿瘤切除不彻底等严重风险。关注每种类型的手术细微差别有助于预防许多此类并发症。有实例证据表明,在我们机构利用影像引导手术辅助肿瘤切除有助于减少出血量和局部复发率,同时在影响骶骨的恶性及侵袭性良性肿瘤中保留功能。
