Total spondylectomy, by either en bloc or piecemeal method, could significantly reduce LRFS for spinal chordoma. Location of C3-L5 is a favorable factor for LRFS, while dedifferentiated subtype and preoperative Frankel scores A-C are adverse prognostic factors. In addition, total en bloc spondylectomy and KPS ≥ 80% significantly improve overall survival of patients with spinal chordoma.
