The metastatic tumor of spine is one of most common metastatic bone tumors. Conservative treatments such as chemotherapy and radiotherapy were preferred in most cases. However neurologic impairments were not improved in most of them, and quality of life was poor. We have reviewed and analysed 13 cases of spine metastatic tumor, who had received surgical treatments for intractable pain and paraplegia, and have a minimum follow up of 4 months at the Department of Orthopaedic Surgery, Catholic University Medical College from Jan. 1986 to Dec. 1991. The purpose of this study was to show the efficacy of the surgical treatments for metastatic lesions in terms of postoperative neurologic improvement and survival time. The results are as follows; 1. Primary tumors were identified in 8 cases; thyroid in 2, lung 2, kidney 2, prostate 1 and cervix 1. 2. Lumbar spine was involved in 6 cases (46%), cervical spine in 4 (30%) and dorsal spine in 3 (27%). 3. Decompressive laminectomy was performed in 8 cases, corpectomy in 4 cases (Moss ring fixation in 3, anterior interbody fusion in 1) and posterior stabilization, corpectomy and Moss ring fixation in 1. 4. Among 8 patients who had preoperative paraplegia, 6 (7596) were improved in neurologic status based on Frankel neurologic deficits. 5. During the follow-up period five patients died in average 6.6 months after operation, and other eight patients are still alive in average 17 months after operative treatment.
