Brief Review of Sarcopenia as a Prognostic Factor for Mortality in Spine Surgery for Metastatic Tumors: Multicenter Retrospective Cohort— Zakaria 2020

This is a brief audio review. In the article Sarcopenia as a Prognostic Factor for 90-Day and Overall Mortality in Patients Undergoing Spine Surgery for Metastatic Tumors: A Multicenter Retrospective Cohort Study published, 2020 by Zakaria and Colleagues, The outcomes and key points are as noted: Sarcopenia, via psoas muscle size, is better than established methods to prognosticate survival like karnofsky performance score, in estimating the 90 day mortality of post operative spinal metastasis patients. Odds ratio 0.16, P=0.001. This was a Retrospective, observational, (Multivariate analysis, >20 variables) with 271 patients who were patients with spinal metastasis undergoing surgery.
