A Complication-Stratified Dual-Stage Ensemble Model for Predicting Postoperative Outcomes in Gastric Cancer Surgery

2026-03-18

Abstract excerpt

<title>Abstract</title> <p> <bold>Background:</bold> Postoperative complications after gastric cancer surgery are characterized by an inherent and irreducible class imbalance (15–20%), which leads to low sensitivity for high-risk patients and heterogeneous length-of-stay (LOS) trajectories. This study aimed to develop and validate a complication-stratified dual-stage ensemble model addressing these methodologic...
