Abstract
PURPOSE: To determine the significance of each parameter of the revised Tokuhashi score and identify which is associated with survival. BACKGROUND: Spinal metastases are common and can be a challenging medical issue. Treatment options depend on patients' prognosis. Many scoring systems in the literature help estimate prognosis, such as the Tokuhashi, revised Tokuhashi, and Tomita scoring systems. METHODS: A retrospective review of all patients from 2003 to 2012 treated for spinal metastases in one center was conducted. Imaging, pathology, and charts were reviewed to determine the modified Tokuhashi scores. Scores were then compared to the actual documented survival. Univariate and multiple regression analyses were used to assess the importance of each individual parameter and survival time. Linear regression was used to determine the relationship between the Tokuhashi score and weighted Tokuhashi score with survival time. RESULTS: A total of 126 patients were reviewed. All parameters in the revised Tokuhashi score were significantly associated with survival time except for primary site using univariate analysis. Only the number of spinal metastases and metastasis to major organs showed statistical significance when multiple variable analysis was used. CONCLUSION: A number of spinal metastases and metastasis to major organs were the most important predictors of actual survival. Modification to the score based on population characteristics would help better identify patients with spinal metastases that can benefit from surgery.
