Critical modules and genes associated with disease progression were identified. The prognostic value and expression changes of these genes were evaluated, and their expression patterns across disease states were validated in external datasets to confirm key genes involved in the inflammation-cancer transformation into gastric cancer.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      WGCNA identified four key modules: pink, purple, red, and magenta. The first three modules were most strongly associated with low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia, and early gastric cancer, respectively, while magenta was linked to all three stages. Functional analysis reveals: Pink module: Enriched in inflammation-related pathways. Purple module: Involved in chemical carcinogenesis and beta-alanine metabolism. Red module: Associated with immune response and inflammation, participating in NF-kappa B and Toll-like receptor signaling pathways. Magenta module: Linked to complement activation and immune response, enriched in cytokine-cytokine receptor interaction and chemokine signaling pathways. Core genes are filtered based on gene significance (GS &amp;gt; 0.2) and module membership (MM &amp;gt; 0.8). Among 20 shared core genes across disease stages, 13 genes (e.g.,\n                      <jats:italic>FCRL3<\/jats:italic>\n                      ,\n                      <jats:italic>EFEMP1<\/jats:italic>\n                      ,\n                      <jats:italic>ANKRD29<\/jats:italic>\n                      ,\n                      <jats:italic>STOX2<\/jats:italic>\n                      ) were identified as unfavorable prognostic factors for gastric cancer.
