    Abstract:
    BACKGROUND Spinal metastases can cause metastatic epidural spinal cord compression (MESCC), which can result in neurological dysfunction and impaired quality of life. This study investigated the safety and effectiveness of posterior decompression surgery and radiofrequency ablation followed by vertebroplasty in spinal metastasis from lung cancer. MATERIAL AND METHODS From June 2008 to September 2015, a retrospective analysis was conducted in 15 patients with spinal metastasis from lung cancer. All cases suffered MESCC and underwent posterior decompression surgery to relieve the compression of spinal cord, and had radiofrequency ablation followed by vertebroplasty. All patients received postoperative multidisciplinary therapy. The operative time, blood loss, complications, pain, neurologic deficit, quality of life, and survival were assessed preoperatively and postoperatively. RESULTS Patients were followed from 6 to 56 months. The mean time of operation was 154±50 minutes and the mean blood loss was 210±90 mL. In the pre-operation analysis found the mean visual analogue scale (VAS) was 7.86±0.86. In the post-operation analysis at 3 months, the mean VAS score was 3.51±1.32. The VAS improved significantly (t=7.95, P<0.01). The Frankel grade was improved 1 grade or 2 grades in 14 patients when pre-operation was compared to post-operation. Only 1 patient kept Frankel grade D after surgery. Eight patients with sphincteric dysfunction preoperatively were improved after surgery. The EORTC QLQ-C30 score was 86.13±8.51 preoperatively and 52.21±13.28 postoperatively. The quality of life was improved significantly (t=11.8, P<0.01). The median survival time was 11 months. CONCLUSIONS Through posterior decompression surgery and radiofrequency ablation followed by vertebroplasty, the quality of life was improved significantly. This palliative treatment was effective and safe in spinal metastasis from lung cancer.
