Objective: To investigate the effectiveness of the Tokuhashi score in predicting the prognosis among Chinese patients with spinal metastasis who underwent the surgeries. Methods: A total of 109 patients with spinal metastasis underwent the surgeries between 2008 and 2018 were enrolled in this study. Rank correlation was used to assess the relationship between Tokuhashi score and the actual survival time. Log-Rank test was used to analyze the survival data. A univariate survival analysis was carried out using the Kaplan-Meier method. Results: There were 68 cases at score 0-8, 37 at score 9-11 and 4 at score 12-15 on the basis of Tokuhashi score. Our findings showed no statistical differences in the actual survival time (R=0.111, P=0.253) and median survival time (P=0.326) among the three scouring groups. The median survival time of score 0-8 was 10.90 (95%CI: 6.40-13.80) months, of score 9-11 was 13.90 (95%CI: 6.20-26.20) months, and of score 12-15 was 59.80 (95%CI: 5.40-59.80) months. Conclusion: Tokuhashi score may be not an accurate tool for predicting the prognostic survival in Chinese patients with spinal metastasis.
