Disclosures • None
Surgery for Spine Metastases • Up to 35% of cancer patients will develop spine metastases • >20,000 new cases each year • Multiple levels of involvement in 40-70% • 12-20% of patients will present with spine symptoms as first manifestation of cancer
Spine Metastases • Because most mets originate in the vertebral body, the site of compression is usually ventral • Tumor infiltration can also cause mechanical instability due to weakening of the bone
Surgery for Spine Metastases • In the past, treatment was primarily radiation • Surgery sometimes offered, but without significant benefit • Retrospective studies demonstrated laminectomy resulted in neurologic improvement in a minority of patients and unsustained (Sorensen et al 1990, Constans et al 1983)
Surgery for Spine Metastases • In addition, outcomes compared to EBRT were equivalent with or without laminectomy (Byrne 1992, Young et al 1980) • Thus, nihilistic attitude regarding role of surgery in metastatic spine disease
Surgery for Spine Metastases In 1980’s, newer techniques of surgery allowed for more aggressive extirpation of disease and reconstruction
Surgery for Spine Metastases RCT recently demonstrated superiority of sugical decompression + EBRT vs. EBRT alone (Patchell, Lancet 2005) Surgery + EBRT both preserved and regained ambulation better than EBRT First Class I study demonstrating advantage of surgery in treatment of metastatic disease
Surgery for Spine Metastases • However, surgery is not without drawbacks • Morbidity as high as 20% in some series • Prolonged hospital time, rehabilitation time • Many patients cannot or are unwilling to tolerate surgery
Surgery for Spine metastasesRecommendations • Indications for surgery: • Rapid neurologic deterioration • Mechanical instability • Intractable radicular pain/myelopathy • Compression due to bony retropulsion • Relatively limited extant of bony disease/compression • Relatively limited extraspinal disease/good performance status • Prognosis > 3 months
Surgery for Spine Metastases • Surgical Approaches now available: • Posterior • Laminectomy • Posterolateral • Transpedicular • Costotransversectomy • Lateral Extracavitary • Lateral/Anterior • Retroperitoneal • Transthoracic
Posterior approach Advantages: Familiar approach, less invasive/morbid Disadvantages: Does not directly address pathology, can cause instability Has fallen out of favor in the surgical treatment of metastatic disease from “Review: complications of surgery for thoracic disc disease”.Fessler RG, Sturgill M.Surg Neurol. 1998 Jun;49(6):609-18
Anterior/Lateral Approach • Advantages: Directly address pathology • Disadvantages: Requires two-stage operation
Surgical Approach • Posterolateral approaches (transpedicular, costotransversectomy) have become increasing popular • Allows for circumferential decompression and stabilization
Posterolateral approach • Requires working around the spinal cord and sacrifice of nerve roots • Less common surgical approach, technically demanding • Small risk of cord infarct with nerve root sacrifice (esp. mid-lower thoracic)
Surgical technique – Transpedicular/Costotransversectomy From Wang et al. March 2004.J Neurosurg Spine. 2004 Oct;1(3):287-98.
Surgical technique – Transpedicular decompression From Wang et al. March 2004.J Neurosurg Spine. 2004 Oct;1(3):287-98.
Surgical technique - Stabilization From Wang et al. March 2004.J Neurosurg Spine. 2004 Oct;1(3):287-98.
Surgery for Spine Metastases Conclusions • For patients with good performance status and relatively limited disease, surgery should be strongly considered • Order of surgery vs RT should be considered as well • PreopRT increases complication rate of surgery
Surgery for Spine MetastasesCurrent/Future Investigations • More aggressive surgical extirpation – e.g. en bloc spondylectomy • Does histology matter? • Less aggressive surgical decompression followed by SRS • Intraoperative radiotherapy • Phase III trials comparing SRS and surgery

Bone Augmentation For Non-surgical Mets YahyaAlbeer, MD Department of RadiologyHenry Ford Health System
Metastatic Bone DiseaseTreatment Goals • Reduce pain • Eradicate or reduce tumor when primary tumors are involved • Prevent neurologic complications • Treat pathologic fractures and prevent recurrent fracture
Primary and Metastatic Bone DiseaseAvailable Treatments - Other1 • Radiation Therapy • Therapeutic: Reduce tumor in primary bone cancer • Palliative: Relieve pain related to bone metastasis • Surgery • To provide stability to compromised bone • To prevent neurologic deterioration after fracture 1. American Cancer Society, 2006.
Results for Tumor Treatment • Kyphoplasty and Vertebroplasty similar • Pain relief in 75-85% of malignant lesions treated with vertebroplasty • The presence of epidural tissue does NOT preclude treatment* • Shimony et al Radiology 2004;232:846-853 • Fourney et al J Neurosurg (Spine 1) 2003; 98:21-30 • J Clin Neurosci 2011 Jun;18(6):763-7.

Q&A Jack Rock, M.D. Department of Neurosurgery
Metastatic Spine Disease: Conclusions Most patients with metastatic disease involving the spine will be managed effectively either with observation or radiation For patients with spinal cord compression and rapidly progressing neurological deterioration or significant neurological compromise (i.e., non-ambulatory), tailored surgical decompression +/- fusion remains the gold standard For ambulatory patients with spinal cord compression, radiosurgery is proving to be effective in most cases As a treatment for painful spinal metastases vertebro- and kyphoplasty are effective augmentation procedures
