19 Disclosures None

20 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

21 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

22 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)

23 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

24 Surgery for Spine Metastases In 1980’s, newer techniques of surgery allowed for more aggressive extirpation of disease and reconstruction

25 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

26 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

27 Surgery for Spine metastases Recommendations 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

28 Surgery for Spine Metastases Surgical Approaches now available: –Posterior Laminectomy –Posterolateral TranspedicularCostotransversectomy Lateral Extracavitary –Lateral/Anterior RetroperitonealTransthoracic

29 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 Jun;49(6):609-18

30 Anterior/Lateral Approach Advantages: Directly address pathology Disadvantages: Requires two-stage operation

31 Posterolateral Approaches

32 Surgical Approach Posterolateral approaches (transpedicular, costotransversectomy) have become increasing popular Allows for circumferential decompression and stabilization

33 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)

34 Surgical technique – Transpedicular/Costotransversectomy From Wang et al. March 2004.J Neurosurg Spine Oct;1(3):

35 Surgical technique – Transpedicular decompression From Wang et al. March 2004.J Neurosurg Spine Oct;1(3):

36 Surgical technique - Stabilization From Wang et al. March 2004.J Neurosurg Spine Oct;1(3):

37 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 –Preop RT increases complication rate of surgery

38 Surgery for Spine Metastases Current/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

41 Metastatic Bone Disease Treatment Goals Reduce pain Eradicate or reduce tumor when primary tumors are involved Prevent neurologic complications Treat pathologic fractures and prevent recurrent fracture

42 Primary and Metastatic Bone Disease Available Treatments - Other 1 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.

46 Q&A Jack Rock, M.D. Department of Neurosurgery

47 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
