Metastatic Spinal Cord Compression as the First Manifestation of Malignancy – A Retrospective Study of Surgical Outcome from Single Institution Spine Tumor Registry

Abstract

Given the limited studies addressing the issue about the effect of different surgical modalities for metastatic spinal cord compression (MSCC) as the first malignancy manifestation, we conducted a retrospective case-control study to evaluate the surgical outcome of MSCC as the first malignancy manifestation. A total of 59 patients who were suspected of having metastatic spinal cord compression and underwent surgery from 2008 to 2017 were enrolled in the study. All patients were categorized into either ‘debulking group’ or ‘palliative group’. The primary outcome was progression-free survival (PFS). The secondary outcomes were overall survival (OS), Frankel scale, and Karnofsky scores. All the outcomes were analyzed with a data cutoff of December 31, 2017. There was a significant difference between groups in progression-free survival (PFS) (p = 0.0036). However, there was no significant difference between groups in the overall survival (OS) (p = 0.8669). Age of onset, gender, duration of symptoms, and location of spinal metastasis, initial Frankel, initial Tomita scores, and initial Karnofsky performance scale showed no significant differences between groups. In conclusion, debulking surgery was shown to provide better neurological recoveries and could be considered first in patients with metastatic spinal cord compression as the first malignancy manifestation.
