Erratum: Preoperative Scoring and Limits of Prognostication: Functional Outcome after Surgical Decompression in Metastatic Spinal Cord Compression

Objective: To determine whether preoperative parameters correlate with the postoperative functional outcome in para- and tetraplegic patients with lung, kidney, breast and prostate cancer and metastatic spinal cord compression (MSCC). Methods: Information on 43 patients undergoing decompressive surgery and rehabilitation for MSCC was reviewed, including primary tumor, age, pre- and postoperative ambulation status, mobility subcategory of the Spinal Cord Injury Measure (mSCIM) and the Tokuhashi score. Differences between groups were analyzed by the nonparametric χ² test, and correlation coefficients (Spearman's rho) were computed. Results: Preoperative ambulation (p < 0.001), the American Spinal Injury Association Impairment Scale (p < 0.001) and the type of operation (p = 0.02) influenced the postoperative functional outcome. Any positive change in the mSCIM was influenced by preoperative ambulation (p < 0.001). Patients with breast carcinoma showed significantly more positive changes in the mSCIM compared with other tumors (p = 0.002). No correlation was found between the treatment categories of the Tokuhashi score and the preoperative ambulatory status (p = 0.13) or the change in ambulation status (p = 0.29). Conclusion: The postoperative functional outcome of MSCC patients shows a linear association between the categories of the Tokuhashi score and the change in ambulation status. We recommend surgical decompression even in a palliative situation (Tokuhashi score 0-8) with the aim of optimizing the short-term rehabilitation outcome. © 2014 S. Karger AG, Basel
