## TL;DR

This paper reviews current and future immunotherapy strategies for treating hepatocellular carcinoma, a deadly liver cancer with limited treatment options.

## Contribution

The paper provides a comprehensive overview of immunotherapeutic approaches and combination strategies to overcome resistance in hepatocellular carcinoma.

## Key findings

- Hepatocellular carcinoma is highly resistant to conventional and modern therapies due to its molecular heterogeneity and immunosuppressive tumor environment.
- Combination immunotherapy strategies may offer new opportunities to overcome immune resistance in advanced hepatocellular carcinoma.
- Immune checkpoint blockade and oncolytic virus therapy are promising but have limited durable clinical responses in hepatocellular carcinoma.

## Abstract

Hepatocellular carcinoma (HCC) accounts for approximately 90% of primary liver cancers and remains a leading cause of cancer-related mortality worldwide. The management of HCC poses a major therapeutic challenge due to its pronounced molecular heterogeneity, frequent late-stage diagnosis, and intrinsic resistance to both conventional and modern therapeutic modalities. Furthermore, the relatively low tumor mutational burden and the presence of a profoundly immunosuppressive tumor microenvironment (TME) substantially limit the efficacy of immune-based interventions, particularly in advanced disease stages. In recent years, novel immunotherapeutic approaches—including immune checkpoint blockade (ICB), oncolytic virus therapy, and genetically engineered immune cell-based therapies—have garnered significant attention. Nevertheless, durable clinical responses and meaningful improvements in overall survival remain limited, underscoring the complexity of achieving effective immune control in HCC. Emerging evidence suggests that rational combination immunotherapy strategies may offer new therapeutic opportunities by overcoming immune resistance mechanisms. In this review, we provide a comprehensive overview of current therapeutic strategies for HCC, with particular emphasis on immunotherapeutic approaches. We discuss common clinical challenges spanning diagnosis to treatment resistance, critically evaluate key clinical trial outcomes, and highlight future directions aimed at improving therapeutic efficacy and long-term disease control.
