More than one-third of patients with cancer have vertebral metastases found at autopsy. Primary and metastatic tumors to the spinal column can lead to pain, instability, and neurologic deficit. Symptomatic lesions are most prevalent in the thoracic spine (70%), followed by the lumbar spine (20%) and cervical spine (10%). Lesions in larger vertebral bodies tend to be asymptomatic given the increased ratio between the diameter of the spinal canal and the traversing nerve roots.
超过三分之一的癌症患者在尸检时发现有椎体转移。脊柱的原发性和转移性肿瘤可导致疼痛、不稳定和神经功能缺损。有症状的病变最常见于胸椎（70%），其次是腰椎（20%）和颈椎（10%）。鉴于椎管直径与穿行神经根之间的比例增加，较大椎体的病变往往无症状。
