The efficacy of percutaneous vertebroplasty for palliation of pain in vertebral metastases associated with solid malignancies

e20670 Background: Painful vertebral metastases are a debilitating and common complication of a number of solid malignancies. Percutaneous vertebroplasty appears beneficial for patients with acute compression fractures of multiple aetiologies including myeloma, and osteoporosis. There are few reports on its use in the setting of metastatic solid malignancy. Methods: We identified all individuals who had undergone percutaneous vertebroplasty at our institution since 2004 and focused on those with metastatic solid malignancies. Their clinical characteristics and outcomes were investigated. Results: From 136 cases that underwent percutaneous vertebroplasties, 19 were performed mainly in breast, prostate, lung, and renal cancers.
