OBJECT: Cervical chordomas are rare lesions and usually bring about challenges in treatment planning because of their wide extension and complicated adjacent anatomy. There are few large published series at present focusing on cervical chordomas. The authors studied a consecutive series of 14 patients with primary cervical chordomas who underwent surgical treatment and were observed between 1989 and 2008. By reviewing the clinical patterns and follow-up data, they sought to investigate the clinical characters, tailor the appropriate surgical techniques, and establish prognosis factors for cervical chordomas. METHODS: Hospitalization and follow-up data in the 14 patients were collected. All patients underwent piecemeal tumor excision and reconstruction for stability; total spondylectomy was achieved in 5 cases. Postoperative radiotherapy was administered in all patients. Kaplan-Meier plots were used to represent tumor recurrence and patient survival, and log-rank testing was used to determine the risk factors of local recurrence. RESULTS: Follow-up ranged from 8 to 120 months (mean 58.6 months). Symptom and neural status in most patients improved after surgery. The 1- and 5-year disease-free survival rates were 78.6% and 50%, respectively, and the 1- and 5-year survival rates were 92.9% and 85.7%, respectively. Log-rank tests revealed that the following variables were significantly associated with a high rate of tumor recurrence: age less than 40 years or greater than 70 years (p = 0.006) and an upper cervical tumor location (p = 0.019). CONCLUSIONS: Chordomas in the cervical spine are usually neoplasms that exhibit insidious growth and a wide extension by the time of diagnosis. Radical intralesional debulking surgery and postoperative radiotherapy have been effective treatment. A limited application of en bloc tumor resection and the highly likely intraoperative intralesional tumor seeding may partially explain the high local recurrence rate, whereas the chance of distant metastases, fortunately, is very low. Most recurrence were documented within 3 years. Some specific surgical techniques should be emphasized to minimize tumor seeding. Patients with upper cervical chordomas, younger adults, and elderly adults have worse prognosis. For patients with chordoma extending to both the anterior and posterior spinal columns, total spondylectomy combined with piecemeal excision is recommended for a better prognosis.
目的:颈椎脊索瘤是一种罕见的病变,由于其广泛的延伸和复杂的毗邻解剖结构,通常在治疗计划中带来挑战。目前很少有大型的已发表系列研究专门针对颈椎脊索瘤。作者研究了 1989 年至 2008 年间接受手术治疗的 14 例原发性颈椎脊索瘤患者的连续系列,并对其临床模式和随访数据进行了回顾,旨在探讨颈椎脊索瘤的临床特征,制定合适的手术技术,并确定预后因素。
方法:收集了 14 例患者的住院和随访资料。所有患者均采用分块肿瘤切除和重建以稳定病情;5 例患者行全脊椎切除术。所有患者均行术后放疗。采用 Kaplan-Meier 图表示肿瘤复发和患者生存情况,采用对数秩检验确定局部复发的危险因素。
结果:随访时间为 8 至 120 个月(平均 58.6 个月)。大多数患者术后症状和神经状态改善。1 年和 5 年无疾病生存率分别为 78.6%和 50%,1 年和 5 年生存率分别为 92.9%和 85.7%。对数秩检验显示,以下变量与肿瘤高复发率显著相关:年龄小于 40 岁或大于 70 岁(p = 0.006)和上颈椎肿瘤位置(p = 0.019)。
结论:颈椎脊索瘤通常是在诊断时表现出隐匿性生长和广泛延伸的肿瘤。根治性肿瘤内切除术和术后放疗是有效的治疗方法。广泛应用整块肿瘤切除术和术中肿瘤内种植的可能性较高,可能部分解释了局部复发率较高的原因,而远处转移的可能性则较低。大多数复发发生在 3 年内。应强调一些特定的手术技术,以最大限度地减少肿瘤种植。上颈椎脊索瘤、年轻成年人和老年人的预后较差。对于肿瘤延伸至前后脊柱柱的患者,建议行全脊椎切除术联合分块切除术以获得更好的预后。
