Updating Prognostic Assessment for Spinal Metastases With a Combined Model of the Spinal Instability Neoplastic Score and the New Katagiri Score.

ABSTRACT: Study DesignProspective Cohort Study.ObjectivesThe rapidly evolving landscape of cancer care alters the prognostic accuracy of established scoring systems for metastatic spinal tumors. This study aimed to provide a contemporary assessment of patient survival and examine the independent and complementary roles of the new Katagiri score (a systemic prognostic tool) and the Spinal Instability Neoplastic Score (SINS, a mechanical instability tool) in predicting 6-month mortality, laying a foundation for future combined prognostic model development.MethodsWe prospectively analyzed 151 patients with metastatic spinal tumors treated between 2021 and 2023. Demographic, clinical, and treatment data, including the new Katagiri score and SINS, were collected. The primary endpoint was 6-month mortalit
