Future perspectives on immunotherapy for hepatocellular carcinoma.

In recent years, several global phase III trials have shown that combinations of immune checkpoint inhibitors (ICIs) offer superior efficacy and survival compared to multi-kinase inhibitors, establishing them as the gold standard for treating patients with advanced hepatocellular carcinoma (HCC). This success has led to investigations into expanding the use of immunotherapy into various other settings and populations, including neoadjuvant and adjuvant therapies, patients with decompensated liver function and those awaiting liver transplantation. Despite its proven efficacy, a significant number of patients still develop resistance to immunotherapy, highlighting the need for innovative strategies to address this challenge. Approaches aimed at enhancing tumour immunogenicity, such as combining immunotherapy with transarterial chemoembolization or radiation therapies, show significant promise. Additionally, novel immunotherapeutics - such as triplet therapy, bispecific antibodies, adoptive T-cell therapy and cancer vaccines - are in early development for HCC. These agents have demonstrated potential for synergistic effects with existing ICIs, with initial studies yielding positive outcomes. In this review, we offer our future perspective on immunotherapy, emphasizing emerging indications, novel combination strategies and the development of new immunotherapeutic agents. Overall, the future of immunotherapy in HCC is brimming with extraordinary potential, set to transform the treatment landscape and redefine the possibilities for managing this challenging disease.
