Background: Determination of the appropriateness of invasive management in patients with spinal metastatic disease requires accurate pre-operative estimation of survival. The purpose of this study was to examine serum alkaline phosphatase as a prognostic marker in spinal metastatic disease.

Methods: Chart reviews from two tertiary care centres were used to identify spinal metastatic disease patients.
