Neurological Outcome Following Surgical Treatment of Spinal Metastases.

BACKGROUND

Spinal metastases lead to bony instability and spinal cord compression resulting in intractable pain and neurological deficits which affect ambulatory function and quality of life. The most appropriate treatment for spinal metastasis is still debated.

OBJECTIVE

The aim of this study is to evaluate clinical outcome, quality of life, complications, and survival after surgical treatment of spinal metastases.

METHODS

Retrospective review of patients with spinal metastases surgically treated at our facility between March 2008 and March 2013 was performed. Evaluations include hospital charts, initial and interval imaging studies, neurological outcome, and surgical complications. Follow-up examinations were performed every 3 months after surgery.

RESULTS

Seventy patients underwent surgical intervention for treatment of spinal metastasis in our institution. There were 27 women and 43 men. The preoperative pain was reported in 65 patients (93%), whereas postoperative complete pain relief was reported in 16 patients (24%), and pain levels decreased in 38 patients (58%). Preoperative 39 patients were ambulant and 31 patients were nonambulant. Postoperative 52 patients were ambulant and 18 patients were nonambulant. Postoperative complications were experienced in 10 (14.2%) patients, and the patient survival rate was 71% (50 patients) at 3 months, 49% (34 patients) at 1 year. The postoperative 30-day mortality rate was 4.2%.

CONCLUSION

Surgical decompression for a metastatic spinal tumor can improve the quality of life in a substantially high percentage of patients with acceptable complications rate.
