Functional enrichment analyses indicated that EIF4A1 was predominantly associated with the neutrophil extracellular trap (NET) network in colon cancer. Strong positive correlations between EIF4A1 expression and neutrophil infiltration were observed in both cancer subtypes. Notably, EIF4A1 exhibited divergent immune infiltration patterns: a strong positive correlation with CD8\n                      <jats:sup>+<\/jats:sup>\n                      T cells in colon cancer, versus a negative correlation with CD4\n                      <jats:sup>+<\/jats:sup>\n                      T cells in rectal cancer. EIF4A1 also showed strong positive correlations with immune checkpoint molecules (PD-1, PD-L1, CTLA4, and LAG-3) in colon cancer, whereas these correlations were weaker in rectal cancer.\n
