    Abstract:
    OBJECTIVE: To evaluate surgical strategy and clinical outcomes for the treatment of thoracolumbar metastatic tumor. METHODS: From January 2009 to December 2010,42 patients with thoracolumbar metastatic tumor were treated surgically. Among the patients, 30 patients were male, and 12 patients were female, ranging in age from 28 to 76 years old, with an average age of 56.8 years old. Twenty-five patients had metastatic tumor in thoracic vertebraes, and 17 patients had metastatic tumor in lumbar vertebraes. Thirty-four patients had metastatic tumor in 1 segment, 6 patients had metastatic tumor in 2 segments and 2 patients had metastatic tumor in 3 segments. Two patients had no symptoms and 40 patients had back or leg pain. Eighteen patients had neurologic deficits, and 5 patients had injuries of A degree, 3 patients had injuries of B degree, 4 patients had injuries of C degree, 6 patients had injuries of D degree according to ASIA grading system. The operation goal was made according to Tomita evaluation. The surgical procedures included pallative decompression, tumor curettage and total vertebrectomy, which were decided based on Tomita classification. The pain, spinal cord function,part control of tumor,survival rate and conditions of internal fixation were evaluated at 1 week, 3 months, 6 months, 1 year and 2 years after operation. RESULTS: One patient died in the operation. Pain relief was obtained in 38 patients after operation. Among 18 patients suffering from spinal cord compromise, 17 patients improved 1 to 4 grades after surgery according to the ASIA grading system. All the patients were followed up and the duration ranged from 24 to 48 months, with a mean time of 34.2 months. Five patients got recurrence. The postoperative survival rates at 3 months, 6 months, 1 year and 2 years were 95.2%, 85.7%, 58.2%, 37.6% respectively. CONCLUSION: According to Tomita system, the different surgical treatments can be selected for patients with spinal metastatic tumors, which can relieve pain, improve the neurological status and spine stabilization, maintain local control, improve quality of life.
