T cell exhaustion markers in hepatitis C virus-related hepatocellular carcinoma: Expression patterns and prognostic significance in an Egyptian cohort

Elevated T cell exhaustion markers were linked to advanced disease and poor survival in Egyptian patients with HCV-related HCC. Machine learning and mediation analyses identified CD4/PD-1 and CD8/TIM-3 as independent prognostic biomarkers, reinforcing their potential as therapeutic targets. These findings provide novel insights from a high-HCV-prevalence setting, supporting the integration of immune exhaustion profiling into risk stratification for HCC.
