Early Postoperative Adverse Events (≤ 30 Days) in Spinal Oncology: Defining the Incidence, Severity, and Predictors in a Mixed Prospective Cohort Including Intradural and Metastatic Spinal Tumors

International Journal of Cancer, Volume 159, Issue 12, Page 2962-2972, 15 December 2026.
ABSTRACT Complication reporting in spinal tumor surgery remains inconsistently defined. We aimed to quantify the incidence, severity, and spectrum of early (≤ 30 days) postoperative adverse events (AEs) in spinal tumor surgery and to identify predictors of overall and serious complications using standardized severity grading.
