Abstract:
Objective To retrospectively study the character, surgical interventions of chordomas in the cervical spine. Methods All the clinical data of 8 cases of chordoma arising in the cervical spine which under went surgical treatment in our department from 1989 to 2006 were retrospectively reviewed, which including 5 males and 3 females. The patients ranged from 34 to 72 years at diagnosis, with an average age of 53.8 years. Surgical interventions were defined according to WBB criteria. 3 patients underwent subtotal centrum or total centrum resection, 2 patients underwent sagital resection and 2 patients received subtotal or total spondylectomy. Extracapsular excision was performed in a intradural invasion case. Autogenic iliac blocks were used as bone graft in 5 cases and titanium mesh with bone cement filling-in for anterior pedestal in 2 cases for reconstructing the stability of spine. Radiation therapy was given as an adjuvant treatment after surgery. Results Symptom of nerve root irritation disappeared or relieved prominently and the patients suffering spinal cord compression symptom got well recovery with at least 1 or 2 levels after operation. The typical “Physaliphorous cell” could be found in the oncologic examination in all those cases. Follow-up average 43.5 months, ranged from 3 to 120 months. All the internal fixation got well fusion and the rate of fusion for the bone graft was 100%. There were 4 cases in which the postoperative local recurrence of the tumor can be seen, with one patient dead of complications of high paralysis, but no local recurrence was observed in the cases which received total spondylectomy. No evidence of distant metastasis was observed in 7 cases for our series except the special intradural case which had the operation history for “sacral chordoma” before. So we consider it as a intradural metastasis case of the primary sacral chordoma. Conclusion Chordomas are rarely seen in the cervical spine and the typical clinical manifestation is rare in pristine cases. So we should think highly of the CT and MR examination for diagnosis. Total spondylectomy with postoperative radiation therapy could lower the rate of local recurrence.
