PurposeThe aim of this study was to discuss the clinical presentation, imaging findings, treatments received, and outcome of therapies for patients with epidural spinal cord compression caused by thyroid spinal metastases, with the goal of emphasizing the importance of surgery in this setting and discussing therapeutic plan for treating these patients.MethodsA total of 22 patients with spinal cord compression due to thyroid tumor spinal metastases who received surgery in our department were identified from 2004 to 2011. The series of 22 patients collected from our institution over the past 7 years was used to discuss treatment options for thyroid cancer spinal metastases on the basis of literature review and our own extensive experience.ResultsThe mean age of the patients in this study was 57 years (range 37-78 years). The duration of the preoperative symptoms was 1-24 months, with an average of approximately 6 months. All patients attained improvement of at least one level of the Frankel classification after surgery. Two patients received more than one operation at our institution. Two patients died during follow-up, two patients had stable disease, and all other patients maintained a disease-free status during follow-up.ConclusionsAs thyroid tumor spinal metastases have a favorable prognosis, a radical therapeutic attitude should be considered in decision-making. Dorsal spinal decompression through curettage and stabilization can preserve or restore neurological function for most patients. For patients who have more than one metastatic lesion of the spine, surgeries can be sequentially performed based on the urgency of the case. In addition to treatment of primary disease, surgery and bisphosphonate treatment are the most important therapies for these patients.
