恶性肿瘤患者发生脊柱转移的几率为30%~40%,在前列腺癌、乳腺癌患者中脊柱转移癌发生率更是高达50%以上。脊柱转移癌会影响脊柱强度引起脊柱不稳,随着病情发展会引起神经根或脊髓受压。在所有恶性肿瘤患者中,出现脊柱转移并引起硬膜外脊髓受压(epidural spinal cord compression,ESCC)的占40%[1]。脊柱转移癌的治疗目标是缓解疼痛、改善神经症状、维持脊柱稳定性、提高患者 The incidence of spondylolisthesis in patients with malignant tumors is 30% to 40%, and the incidence of spinal metastases in patients with prostate cancer and breast cancer is as high as 50% or more. Spinal metastases can affect spine strength causing spinal instability, which can cause nerve root or spinal cord compression as the condition progresses. Spinal metastases occur in 40% of all malignant tumors and cause epidural spinal cord compression (ESCC) [1]. The goal of treatment for spinal metastases is to relieve pain, improve neurological symptoms, maintain spinal stability, and improve patient outcomes
