目的 :研究脊柱骨巨细胞瘤的影像学特点 ,探讨手术方式及对其预后的影响。 方法 :5 6例均行手术治疗 ,早期实施单纯肿瘤病灶切除术 ,后期施行肿瘤整块切除术和病椎次全切除术 ,同时给予坚强的内固定。结果 :术后所有患者局部疼痛均有不同程度的缓解 ,77.3 %的患者神经体征得到改善。随访 42例 (平均随访 5年 4个月 )中预后良好无复发者 2 5例 ( 5 9.5 % ) ,局部仍有瘤灶存在但病变不超过术前者 11例 ( 2 6.2 % ) ,病变扩大、恶变倾向或肺部转移者 6例 ( 14 .3 % )。 结论 :脊柱骨巨细胞瘤之影像学表现有其特殊性 ;肿瘤彻底切除、植骨融合及坚强的内固定是手术成功的关键 ,单纯肿瘤病灶切除术存在一定的复发率 ;骨巨细胞瘤的临床行为具有一定的不可测性
Objective: To study the imaging features of giant cell tumor of the spine and to explore the surgical method and its influence on the prognosis. Methods : Sixty-six patients underwent surgical treatment. Early neoplastic resection was performed. Tumor resection and subtotal lobectomy were performed at the same time. Strong internal fixation was also given. RESULTS: Local pain was relieved to varying degrees in all patients after surgery, and neurological signs improved in 77.3% of patients. During the follow-up of 42 patients (mean follow-up 5 years and 4 months), there were 25 patients with good prognosis without recurrence (55.5%), and local lesions still existed but the lesions did not exceed 11 (26.2%) before surgery. There were 6 cases (14. 3%) with malignant transformation tendency or pulmonary metastasis. Conclusion: The imaging findings of giant cell tumor of the spine have its particularity; thorough tumor resection, bone graft fusion and strong internal fixation are the key to successful operation. There is a certain recurrence rate in simple tumor resection; giant cell tumor of bone Clinical behavior is untestable
