EMG/NCS, diagnostic injection; and 6) medical comorbidities included: obesity, anxiety/depression, extent of cancer, smoking, spinal cord injury and pre-existing chronic pain diagnosis. Consensus was reached for three descriptive categories necessary to comprehensively describe and spine cancer related pain including location, pain characterization and radiographic findings. Additional important variables helpful in guiding treatment decisions were included as modifiers. These were subsequently consolidated into a mechanism-based classification defining Mechanical (Axial/Radicular), Inflammatory (Axial/Radicular) and Neuropathic (Central/Peripheral) (see also Figure 1). Conclusion Expert consensus was reached regarding the key spine tumor pain assessment elements and a classification system was developed. This will provide the foundation for systematic evaluation and reporting of spine cancer-related pain and facilitate research and therapeutic decisions.
