Time for hepatocellular carcinoma immunotherapy:insights for successful clinical applications in this challenging tumor

摘要

The multiplicity and phenotype of intratumoral immune infiltrate have been shown to influence the clinical outcome of hepatocellular carcinoma (HCC), thus providing a strong rationale to therapeutic interventions aimed at restoring the dysfunctional immune response against the tumor. Improving the knowledge of the complex interactions between transformed hepatocytes, nonparenchymal resident cells, and infiltrating immune cells (characterizing the HCC microenvironment) will be instrumental to increase the success rate of existing immunotherapeutic strategies and to identify new potential targets for intervention or biomarkers to optimize the selection of candidate patients.
