AbstractBackground: Colon cancer is a highly aggressive gastrointestinal malignancy with significant global health implications. Although mitochondrial ferroptosis-related genes have been implicated in colon cancer progression, their prognostic significance remains inadequately understood.Methods: We conducted a comprehensive analysis of the expression patterns and prognostic value of mitochondrial ferroptosis-related genes in patients with colon cancer, utilizing data from the TCGA and GEO databases. A prognostic risk model was established, followed by evaluations of the tumor microenvironment (TME), immune cell infiltration, tumor mutation burden (TMB), and predicted drug sensitivity.Results: Four key mitochondrial ferroptosis-associated genes—PDSS2, GRSF1, SLC39A8, and P4HA1—were identified. A nomogram combining the risk score and pTNM stage was constructed to predict patient outcomes. Immune microenvironment analysis revealed distinct differences in immune cell infiltration between the high- and low-risk groups. The risk score was significantly correlated with the expression of TME-related genes and immune checkpoint molecules, suggesting a more immunosuppressive microenvironment in high-risk patients. Furthermore, integrating the risk score with TMB enhanced the accuracy of survival prediction.Conclusions: This mitochondrial ferroptosis-based risk model represents a promising prognostic biomarker and may offer valuable insights for personalized treatment strategies in colon cancer management.Keywords: Colon cancer, Prognostic biomarker, Mitochondrial ferroptosis, Tumor microenvironment, Immunotherapy, Drug sensitivity.
