Primary Malignant Tumors of the Spine

Primary malignant tumors of the spine account for less than 5% of primary bone tumors. Data from the SEER program suggest that the most common bone sarcomas are osteosarcoma, chondrosarcoma, Ewing's sarcoma, chordoma, and malignant fibrous histiocytoma/fibrosarcoma. During the last two decades, tremendous progress has been made in clinical aspects, surgical approaches, and reconstruction with instrumentation at all levels of the spine. Stabilization procedures, including vertebroplasty and kyphoplasty, have further allowed palliation of pain and symptom relief from compression fractures. Improved radiation techniques have offered the potential for improved local control. This article reviews the changes in surgical philosophy in the management of malignant spinal tumors during the past two decades.
