Objective To investigate the clinical characteristics, surgical staging of primary tumors of cervical spine, the effects of different surgical approach and operative method. Methods The location, characteristics,surgical staging, clinical manifestation of tumors, different operative approach and opertative methods were described respectively. Surgical staging of the tumors in 45 cases was divided into four stages 10 cases in stageⅠ,11 cases in stage Ⅱ, 9 cases in stage Ⅲ, 15 cases in stage Ⅳ. Eleven cases were treated with intracapsule excision, 18 cases by marginal excision, 15 cases by wide excision. Results The following up period lasted from 6 months to 10 years(average 3 years). One case with upper cervical spine tumor died from quadriplegia, respiratory and circulatory failure 10 days after operation. The short term results after operation were satisfactory in 44 cases. The local pain and neurological symptoms were improved or resolved. Megrim in 2 cases disappeared;1 cases with malignant nerve sheath tumors and 1 cases with chondrosarcoma died from metastasis, and systemic failure in 13 months, 24 months. Tumors focus recurred one year after the surgery in 1 case with osteoblastomas, 1 case with chondrosarcoma and 1 case with giant cell tumor. Conclusion The surgical approach and operative methods must be selected according to the location, surgical staging, characters of tumors; operative methods and postoperative comprehensive therapy play important roles on prognosis of the tumor cases.
