This is a prospective, multicenter, observational study focusing on assessing and managing pain in patients with metastatic spinal tumors. Pain from spinal metastases adversely impacts quality of life, function, and treatment outcomes. Advances in surgical techniques have shown significant benefits. However, previous studies either lacked nuanced differentiations or simply categorized pain as mechanical or non-mechanical; explaining the highly variable pain outcome measurements in these studies. This study employs the AO Spine Cancer-Related Pain Classification to better categorize neoplastic spinal pain by etiology.
