Core Tip

Core Tip: Hepatocellular carcinoma linked to hepatitis C virus (HCV) is a major health burden in Egypt. This study comprehensively evaluated T cell exhaustion markers, programmed death 1, T cell immunoglobulin and ITIM domain, and T cell immunoglobulin and mucin domain-containing protein 3, on CD4+ and CD8+ T cells across HCV-related liver disease stages. Using advanced analyses, including Random Forest modeling, Cox regression, and mediation analysis, we identified CD4 programmed death 1 and CD8/T cell immunoglobulin and mucin domain-containing protein 3 as robust prognostic biomarkers of poor survival. These findings highlight novel immune targets for risk stratification and potential immunotherapy in HCV-related hepatocellular carcinoma.
