Accuracy of Preoperative Scoring Systems for the Prognostication and Treatment of Patients with Spinal Metastases.

Abstract

BACKGROUND: In patients with spinal metastatic disease, survival prognosis is a key consideration in selection for surgery and determining the extent of treatment. Individual survival prediction however remains difficult. We sought to validate the prognostic accuracy of seven preoperative scoring systems. METHODS: 61 patients surgically treated for spinal metastases were retrospectively reviewed. Preoperative scores were calculated for Tokuhashi, Revised Tokuhashi, Bauer, Modified Bauer, Sioutos, Tomita, and van der Linden scoring systems. Prognostic value was determined by comparison of predicted and actual survival. RESULTS: The Revised Tokuhashi and Modified Bauer scoring systems had the ..
