Core Tip

Core Tip: Recent developments in the field of hepatocellular carcinoma have drawn attention to the immune aspects of this neoplasm. Understanding the immune features of hepatocarcinogenesis is instrumental in order to comprehend current advances in immune markers and immunotherapy. Intensifying research on immune markers may improve surveillance and allow for precision medicine. Immunotherapy is already first-line treatment for advanced hepatocellular carcinoma.
