Special Issue Information

Dear Colleagues,

Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver. In recent years, the management of patients with HCC has changed considerably, due to improvements in molecular biology knowledge and the introduction of immunotherapy. To date, systemic therapy is authorized in patients with advanced HCC.

Moreover, there is increasing evidence that immunotherapy could also play a role as an adjuvant therapy in intermediate stages, pre-transplant downstaging, or post-liver-transplant recurrence.

Despite improvements over the years, these indications are not fully endorsed or stated in the guidelines due to the absence of studies and trials.

This Special Issue aims to explore the field of immunotherapy in liver cancer, evaluating innovative aspects and developing those that are poorly defined or already addressed. A first objective will be to gather evidence on the potential role of immunotherapy in all stages, not just the advanced stage.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: the role of immunotherapy in all stages of liver cancer and in combination with other treatment techniques. In addition, interesting data may concern the effect of immunotherapy on the tumor microenvironment.

We look forward to receiving insightful contributions.

Objectives: This study focused on the presence or absence of vascular invasion and extrahepatic metastasis in hepatocellular carcinoma (HCC) and examined their impact on systemic treatment outcomes. Methods: We retrospectively analyzed 362 patients with unresectable HCC who received first-line systemic therapy. The prognostic evaluation was based on the presence of vascular invasion and extrahepatic metastasis at the time of treatment initiation. Results: Patients with vascular invasion or extrahepatic metastasis (advanced group) had significantly worse outcomes than those without these features (intermediate group), with median survival times of 434 and 658 days, respectively. Further subdivision of the advanced group into three categories—patients with only extrahepatic metastasis (m group, n = 77), patients with only vascular invasion (v group, n = 78), and patients with both vascular invasion and extrahepatic metastasis (vm group, n = 52)—revealed that the m group had significantly better outcomes than those in the other two groups, with median survival times of 649, 323, and 187 days, respectively. A comparison of the clinical backgrounds among the three groups demonstrated that the m group had significantly better liver function at the time of treatment initiation than that in the other two groups. Multivariable analysis, including performance status, Child–Pugh score, and the use of immune checkpoint inhibitors as first-line therapy, identified the m group as an independent and significant prognostic factor (hazard ratio, 0.50). Conclusions: Unresectable HCC with extrahepatic metastasis and no vascular invasion represents a novel staging category for systemic treatment. Full article
