Percutaneous vertebral augmentation in metastatic disease: state of the art.

Improvements in diagnosis and treatment have prolonged cancer survival, with a consequent increase in the incidence of spinal metastases and vertebral compression fractures with associated axial pain, progressive radiculomyelopathy, and mechanical instability. Pain relief in malignant vertebral compression fractures is key to achieving a better quality of life in patients under palliative care. The gold standard for pain relief is nonsteroidal anti-inflammatory drugs and opioids. Nonresponsive cases are then treated with radiotherapy, which may require 2-4 weeks to take effect and in most cases does not provide complete pain relief. Percutaneous vertebroplasty and percutaneous kyphoplasty can in particular give relief in patients with vertebral body compression fractures that do not cause neurological deficits but severely compromise quality of life because of intractable pain.

Multimodal approach to the management of metastatic epidural spinal cord compression (MESCC) due to solid tumors.

PURPOSE: To assess the impact of a multidisciplinary approach for treatment of patients with metastatic epidural spinal cord compression in terms of feasibility, local control, and survival. METHODS AND MATERIALS: Eighty-nine consecutive patients treated between January 2004 and December 2007 were included. The most common primary cancers were lung, breast, and kidney cancers. Ninety-eight surgical procedures were performed. Radiotherapy was performed within the first month postoperatively. Clinical outcome was evaluated by modified visual analog scale for pain, Frankel scale for neurologic deficit, and magnetic resonance imaging or computed tomography scan. Nearly all patients (93%) had back pain before treatment, whereas major or minor preoperative neurologic deficit was present in 62 cases (63%). RESULTS: Clinical remission of pain was obtained in the vast majority of patients (91%). Improvement of neurologic deficit was observed in 45 cases (72.5%). Local relapse occurred in 10%. Median survival was 11 months (range, 0-46 months). Overall survival at 1 year was 43.6%. Type of primary tumor significantly affected survival. CONCLUSIONS: In patients with metastatic epidural spinal cord compression, the combination of surgery plus radiotherapy is feasible and provides clinical benefit in most patients. The discussion of each single case within a multidisciplinary team has been of pivotal importance in implementing the most appropriate therapeutic approach.
