Construction of a Prognostic Model for Lung Adenocarcinoma Based on Necrosis by Sodium Overload-Related Genes and Identification of DENND1C as a New Prognostic Marker.

ABSTRACT: Background: Lung adenocarcinoma (LUAD) remains a leading cause of cancer-related mortality. The prognostic significance and functional role of sodium overload-induced necrosis (a novel form of regulated cell death driven by disrupted sodium homeostasis, hereafter abbreviated as NECSO) in LUAD are largely unexplored. Methods: A prognostic model was constructed utilizing the NECSO key gene TRPM4 and analyzed through Cox, LASSO, and multivariate Cox regression analyses. LUAD patients were stratified into high- and low-risk groups. The model's predictive performance was evaluated using time-dependent ROC curves and nomograms. Functional enrichment analysis elucidated underlying biological disparities. The tumor immune microenvironment was characterized using ESTIMATE, ssGS
