RESUMO
The spine is a common site for metastatic tumors, with 5%-10% of patients developing epidural spinal cord compression (ESCC), which significantly reduces their quality of life and accelerates the process of death. When total en-bloc spondylectomy (TES) radical surgery does not achieve the desired tumor control, palliative care remains the primary treatment option. Traditional laminar decompression or partial tumor resection can only relieve local compression. Although the surgical trauma and complications are less, these methods cannot effectively address tumor recurrence and secondary compression. Therefore, separation surgery combined with radiofrequency ablation and bone cement strengthening was used to treat thoracolumbar metastatic tumors, aiming to achieve good clinical results. In this protocol, the steps and key points of separation surgery combined with radiofrequency ablation and bone cement reinforcement for thoracolumbar metastatic tumors are introduced in detail. Meanwhile, the clinical data of 67 cases of thoracolumbar metastatic tumors in our hospital meeting the inclusion criteria were retrospectively analyzed. Different treatment methods divided the patients into two groups: separation surgery combined with radiofrequency ablation and bone cement strengthening (group A, 33 cases) and the radiotherapy group (group B, 34 cases). All patients were evaluated using improved Tokuhashi, Tomita, SINS, and ESCC scores before treatment. VAS score, Frankel grading, and Karnofsky scores during different periods of the two treatments were compared to assess the clinical outcomes. Studies have shown that separation surgery combined with radiofrequency ablation and bone cement strengthening can significantly reduce pain, promote neurological function recovery, enhance mobility, and improve quality of life in treating thoracolumbar metastatic tumors.
