The Spine Service at MSKCC: Multidisciplinary Care
•Spine oncology requires multidisciplinary care
•Spine conference
•All physicians in the hospital bring their spine patient questions for multidisciplinary assessment—meets weekly
•Spine clinic
• Joint clinic with neurosurgery, interventional radiology and radiation oncology
•NOMS assessment

Radiosurgery Recommendations
A strong recommendation can be made with low-quality evidence that radiosurgery should be considered over
conventional fractionated radiotherapy for the treatment of solid tumor spine metastases in the setting of
oligometastatic disease and/or radioresistant histology in which no relative contraindications exist.

A strong recommendation is made that patients with solid
renal cell carcinoma in the absence of epidural disease
may benefit from stereotactic radiosurgery as first line
therapy rather than en bloc excision.

NOMechanical InstabilityS
•Recognition of instability as an indication for surgery or percutaneous cement augmentation prior to RT
•Spine Oncology Study Group (SOSG) created a scoring system Spine Instability Neoplastic Score or SINS1
-Integrates systematic literature review with expert opinion
-Reliable: High inter and intra-relater reliability2
-Valid: Substantial agreement between SINS score and expert opinion2

Summary
•NOMS provides a comprehensive approach to the multidisciplinary management of spine metastases
•Metastatic cancer patients are a unique cohort
•Integration of new technologies and therapeutic options
•Most effective and low impact = best palliatiion
•NOMS provides a vehicle for surgeons, medical and radiation oncologists to speak a common language
