Relationship Between Paralysis and the Epidural Spinal Cord Compression Scale in Spinal Metastasis.

This study is the first to examine the relationship between the epidural spinal cord compression (ESCC) scale, which measures circumferential compression, and the functional outcomes of treatment, which were assessed at regular intervals after treatment until death. A total of 191 patients who had grade D or worse paralysis on the American Spinal Injury Association (ASIA) classification scale and a grade 1b or more severe cord compression on the ESCC scale were included in the study. Patients had been treated with surgery combined with radiotherapy (n=146) or radiotherapy alone (n=45). Three spinal surgeons assessed the ESCC grade of for patient, and the grade agreed to by at least 2 surgeons was adopted. After 4 weeks, re-evaluations were conducted by the same examiners. The authors also calculated the mean kappa coefficients for inter- and intra-examiner variability (0.88 and 0.93, respectively). The distribution of the ASIA grade differed significantly among the ESCC scale grades (P=.0102). However, the degree of improvement in paralysis in terms of the ASIA grade (≥1 grade of improvement, no change, or ≥1 grade of aggravation) was not significantly associated with the ESCC grade (P=.2334). The ESCC scale was found to be a useful indicator of circumferential spinal cord compression but was not identified as a significant functional prognostic factor for paralysis.
