BACKGROUND: Since chordoma is refractory to chemotherapy and conventional radiotherapy, radical surgical resection is mandatory. However, it is surgically demanding in the craniocervical junction (CCJ) and upper cervical spine. OBJECTIVE: To analyze long-term surgical results of cervical chordomas. METHODS: We retrospectively reviewed 12 consecutive patients who underwent surgical treatment for CCJ or upper cervical chordomas from 2001 to 2009 in 2 academic institutions. We analyzed the progression-free survival and overall survival and compared the results between gross total resection (GTR) cases and partial resection (PR). Complications were analyzed by comparing primary and recurrent tumor. We also delineated the type of radiotherapy. RESULTS: Of the 12 patients, 5 underwent GTR and 7 underwent PR. GTR of the tumor was achieved by intralesional piecemeal removal. No recurrence occurred in the GTR group. PR group had 6 cases of regrowth (85.7%). Ten patients (83.3%) underwent any kind of radiation therapy. There were 3 (60%) patients in the GTR group and 7 (100%) in the PR group. Compared to PR, GTR revealed a better 3-yr progression-free survival rate (100% vs 14.3%) as well as a better 3-yr overall survival rate (100% vs 71.4%). Surgical complication rate (40% for GTR vs 42.9% for PR) was not significantly different between the groups. The surgical complication rates of primary and revision surgery were 25% and 75%, respectively. Complication associated with radiation occurred in 2 patients. CONCLUSION: Gross total intralesional piecemeal resection with perioperative radiation therapy is an acceptable strategy for CCJ and the upper cervical chordoma management.
背景:由于 chordoma 对化疗和常规放疗具有抗性,因此必须进行根治性手术切除。然而,在颅颈交界区(CCJ)和颈椎上部进行手术具有很高的要求。
目的:分析颈椎 chordoma 的长期手术结果。
方法:我们回顾性分析了 2001 年至 2009 年在 2 所学术机构中接受手术治疗的 12 例 CCJ 或颈椎上段 chordoma 患者的资料。我们分析了无进展生存率和总生存率,并比较了完全切除(GTR)病例和部分切除(PR)病例的结果。通过比较原发性肿瘤和复发性肿瘤分析并发症。我们还描绘了放疗类型。
结果:12 例患者中,5 例接受 GTR,7 例接受 PR。肿瘤的 GTR 通过肿瘤内部分切除实现。GTR 组无复发。PR 组有 6 例复发(85.7%)。10 例患者(83.3%)接受了任何形式的放射治疗。GTR 组有 3 例(60%),PR 组有 7 例(100%)。与 PR 相比,GTR 具有更好的 3 年无进展生存率(100%比 14.3%)和更好的 3 年总生存率(100%比 71.4%)。GTR 组的手术并发症发生率(40%)与 PR 组(42.9%)无显著差异。初次手术和翻修手术的并发症发生率分别为 25%和 75%。2 例患者发生与放疗相关的并发症。
结论:在围手术期进行 GTR 肿瘤内部分切除和放射治疗是治疗 CCJ 和颈椎上段 chordoma 的一种可接受的策略。
