Management of advanced hepatocellular carcinoma is challenging. With an increasing number of options for the first and second-line treatment, understanding and developing optimal systemic treatment strategies are crucial. In second line, two tyrosine kinase inhibitors (TKI) and one monoclonal antibody have been approved after sorafenib by both the European Medicines Agency and the Food and Drug Administration based on the results of phase 3 trials: cabozantinib, regorafenib and ramucirumab. Cabozantinib has demonstrated an improved overall survival and progression-free survival in the phase 3 CELESTIAL study in second and third line, in patients in good general condition (performance status 0– 1) and with a normal liver function Child-Pugh class A. Analysis of subgroups has shown that even elderly patients over 65 years, or patients with high baseline alpha-fetoprotein ≥ 400 ng/mL benefit from cabozantinib. The choice in second-line between the three drugs should be based on factors such as previous tolerance of sorafenib, safety profile of drugs and quality of life. In this review, we will analyze clinical data available on cabozantinib, clarifying the choice between the different possible treatments. However, the upcoming of a new standard in first line with the combination atezolizumab and bevacizumab will change the game and will warrant further investigations to define the accurate subsequent sequence of TKIs. Cabozantinib is also actually tested in first-line in combination with atezolizumab, results of the phase 3 COSMIC trial are eagerly awaited.

Hepatocellular carcinoma (HCC), the most prevalent malignancy of the digestive tract, is characterized by a high mortality rate and poor prognosis, primarily due to its initial diagnosis at an advanced stage that precludes any surgical intervention. Recent advancements in systemic therapies have significantly improved oncological outcomes for intermediate and advanced‐stage HCC, and the combination of locoregional and systemic therapies further facilitates tumor downstaging and increases the likelihood of surgical resectability for initially unresectable cases following conversion therapies. This shift toward high conversion rates with novel, multimodal treatment approaches has become a principal pathway for prolonged survival in patients with advanced HCC. However, the field of conversion therapy for HCC is marked by controversies, including the selection of potential surgical candidates, formulation of conversion therapy regimens, determination of optimal surgical timing, and application of adjuvant therapy post‐surgery. Addressing these challenges and refining clinical protocols and research in HCC conversion therapy is essential for setting the groundwork for future advancements in treatment strategies and clinical research. This narrative review comprehensively summarizes the current strategies and clinical experiences in conversion therapy for advanced‐stage HCC, emphasizing the unresolved issues and the path forward in the context of precision medicine. This work not only provides a comprehensive overview of the evolving landscape of treatment modalities for conversion therapy but also paves the way for future studies and innovations in this field. Setting a foundation for future research and advancements in HCC treatment, aligning with the emerging paradigm of precision medicine; addressing the need for a holistic approach in managing advanced‐stage HCC, and advocating for a balance between aggressive treatment and quality of life considerations.

INTRODUCTION:The efficacy and safety of combined immunotherapy and transarterial radioembolization (TARE) were suggested in preclinical and early-phase trials, but these were limited by small sample sizes. We sought to compare the efficacy of combined therapy and immunotherapy alone in patients with advanced hepatocellular carcinoma (HCC).METHODS:The National Cancer Database was used to identify patients with advanced HCC diagnosed between January 1, 2017, and December 31, 2019. We included patients who received combined therapy or immunotherapy alone as first-line treatment. Multivariable logistic regression was conducted to determine predictors of combined therapy. Kaplan-Meier and Cox regression approaches were used to identify predictors of overall survival and to compare hazards of mortality between the patients who received combined therapy and immunotherapy alone.RESULTS:Of 1,664 eligible patients with advanced-stage HCC, 142 received combined TARE/immunotherapy and 1,522 received immunotherapy alone. Receipt of combination therapy was associated with care at an academic center and inversely associated with racial/ethnic minority status (Hispanic and Black individuals). The median overall survival was significantly higher in the combination group than in the immunotherapy alone group (19.8 vs 9.5 months). In multivariable analysis, combined therapy was independently associated with reduced mortality (adjusted hazard ratio 0.50, 95% confidence interval: 0.36-0.68, P < 0.001). Results were consistent across subgroups and in sensitivity analyses using propensity score matching and inverse probability of treatment weighting.DISCUSSION:The combination of TARE and immunotherapy was associated with improved survival compared with immunotherapy alone in patients with advanced-stage HCC. Our findings underly the importance of large clinical trials evaluating combination therapy in these patients.

Anlotinib, a novel multi-targeting tyrosine kinase inhibitor (TKI), has been investigated in a variety of malignant tumors. This retrospective study was designed to investigate the efficacy and safety of anlotinib as first- or second-line therapy for advanced or metastatic hepatocellular carcinoma (HCC), and to identify early predictors for disease control. This multicenter retrospective study included 158 patients with advanced HCC. 54 patients received anlotinib and 104 patients received sorafenib. Progression-free survival (PFS), overall survival (OS), and treatment response were compared. Subgroup analyses and biomarker evaluations were also conducted. Anlotinib demonstrated significantly improved OS compared with sorafenib in the second-line setting (13.0 vs. 11.0 months; P  = 0.010), although no significant differences in ORR, DCR, or PFS were observed. Subgroup analyses revealed that patients with AFP ≥ 400 ng/mL or HBV infection derived greater OS benefit from anlotinib. AFP response—defined as a ≥ 25% reduction at 4 weeks—was identified as an independent early predictor of disease control, and this association held true in both high-AFP and low-AFP subgroups. Anlotinib showed encouraging survival benefits and acceptable safety in advanced HCC, particularly in the second-line setting. AFP response may serve as an early biomarker for treatment efficacy. These findings warrant validation in future prospective studies.

Molecular targeted therapy combined with immunotherapy significantly improves the prognosis of patients with advanced liver cancer. Additionally, hepatic arterial infusion chemotherapy (HAIC) can improve the prognosis of patients with advanced liver cancer. This real-world study aimed to evaluate the clinical efficacy and safety of HAIC combined with molecular targeted therapy and immunotherapy in the treatment of primary unresectable hepatocellular carcinoma (uHCC). A total of 135 patients with uHCC were enrolled in this study. Progression-free survival (PFS) was the primary endpoint. The efficacy of the combination therapy was assessed based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST) guidelines. Overall survival (OS), adverse events (AEs) and surgical conversion rate were the secondary endpoints. Univariate and multivariate Cox regression analyses were performed to examine independent prognostic factors. For sensitivity analysis, inverse probability weighting (IPW) was used to balance the influence of the tested confounding factors between groups to verify the robustness of conversion surgery for survival benefits. The E-values were estimated to assess robustness to unmeasured confounders. The median number of therapies was three. Approximately 60% of the patients had portal vein tumour thrombosis (PVTT). The most common targeted drugs were lenvatinib and bevacizumab, whereas the most common immunotherapy drug was sintilimab. The overall objective response rate (ORR) was 54.1%, and the disease control rate (DCR) was 94.6%. A total of 97 (72%) patients experienced AEs of grades 3-4. Fatigue, pain and fever were the most common symptoms of grade 3-4 AEs. The median PFS was 28 months and 7 months in the successful and unsuccessful conversion groups, respectively. The median OS was 30 months and 15 months in the successful and unsuccessful conversion groups, respectively. Successful conversion surgery, sex, hapatic vein invasion, BCLC stage, baseline tumour size, AFP levels and maximum therapeutic response were independent prognostic factors for PFS. Successful conversion surgery, number of interventions, hapatic vein invasion and total bilirubin levels were independent prognostic factors for OS. After IPTW, no standardised differences exceeding 0.1 were found. IPW-adjusted Kaplan-Meier curves showed that successful conversion surgery was an independent prognostic factor for both PFS and OS. The E-values of successful conversion surgery were 7.57 and 6.53 for OS and PFS, respectively, which indicated a relatively robust impact of successful conversion surgery on the prognosis of patients. Patients with primary uHCC undergoing HAIC combined with immunotherapy and molecular targeted therapy have a higher tumour regression rate and the side effects are manageable. Patients undergoing surgery after combination therapy have survival benefits.

Abstract Background Unresectable hepatocellular carcinoma (uHCC) is a leading cause of cancer death. FDA-approved first-line systemic therapies include atezolizumab/bevacizumab (atezo/bev) and durvalumab/tremelimumab (durva/treme); however, there is a lack of comparative data. Methods We reviewed outcomes of patients with uHCC who initiated atezo/bev or durva/treme between 2017 and 2024, across six institutions. Overall survival (OS) and time to treatment discontinuation (TTD) were analyzed using the Kaplan–Meier and Cox models, adjusting for baseline characteristics. Results Four hundred fifty-two uHCC pts were included. Median age: 68 years; 77% male; 81% white. Most common etiologies were viral hepatitis (38.9%) and metabolic dysfunction-associated steatohepatitis (19.5%). Disease progression was the primary reason for treatment discontinuation, atezo/bev (56%) and durva/treme (42%). Outcomes were not statistically significant (median OS [month, m]: 14.0 vs 14.6 [P = .66]; median TTD [m]: 4.9 vs 3.9 [P = .42] for atezo/bev vs durva/treme). Outcomes were significantly different between Child-Pugh classes (CP: A, B7, B8/9, C) respectively, median OS(m): 19.0, 6.1, 5.1, 2.0 (P < .001); median TTD(m): 6.1, 2.3, 3.0, 1.3 (P < .001). Conclusions In this real-world study of uHCC, no significant difference in clinical outcomes was observed between atezo/bev and durva/treme in the first-line setting. CP scores were a key prognostic variable with both regimens.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and is the leading cause of cancer-related deaths worldwide. The majority of patients with HCC are diagnosed at an advanced stage, resulting in limited treatment options. In recent years, numerous clinical trials have confirmed that immunotherapy, particularly anti-programmed cell death 1 (anti-PD-1)/programmed cell death ligand 1 (PD-L1), has emerged as a promising treatment for advanced HCC. However, in real-world practice, the clinical efficacy of adding immunotherapy to locoregional therapies remains unknown, representing a knowledge gap. This meta-analysis aims to evaluate the clinical efficacy of immunotherapy combined with locoregional therapies, including transarterial chemoembolization (TACE), hepatic artery infusion chemotherapy (HAIC), and HAIC/TACE combined with targeted agents, versus locoregional therapies alone in patients with advanced HCC. Eligible studies were identified by searching Embase, PubMed, Cochrane Library, and Web of Science. The clinical outcomes were overall survival (OS), progression-free survival (PFS), disease control rate (DCR), objective response rate (ORR), and adverse events (AEs). Pooled hazard ratios (HRs), odds ratios (ORs), and meta-regression were used to estimate clinical outcomes. Quality assessments were performed using the Newcastle-Ottawa Quality Assessment Form. The funnel plot was used for detecting publication bias. Nineteen cohort studies with 3,720 patients with advanced HCC were included. The immunotherapy-added group was superior in prolonging OS [HR = 0.36, 95% confidence interval (CI) (0.29, 0.46) and < 0.001], PFS [HR = 0.41, 95% CI (0.31, 0.54) and < 0.001], DCR [OR = 2.17, 95% CI (1.80, 2.62), < 0.001], and ORR [OR = 1.85, 95% CI (1.62, 2.12), < 0.001]. The immunotherapy-added group had a higher risk of developing grade ≥3 AEs as compared to the locoregional-only therapy group [OR = 1.26, 95% CI (1.06, 1.49), = 0.009]. Pooled results also indicated an increased risk of fatigue (OR = 1.17, = 0.04), pneumonitis (OR = 2.97, < 0.01), and myocarditis (OR = 9.08, = 0.01) in the immunotherapy-added group. This meta-analysis compared the clinical outcomes of locoregional therapies versus immunotherapy plus locoregional therapies. This study found that adding immunotherapy was associated with improved OS, PFS, DCR, and ORR in patients with advanced HCC compared with those treated with locoregional regimens alone. Meanwhile, the addition of immunotherapy may be associated with an increased risk of grade ≥3 AEs and specific immune-related AEs in patients with advanced HCC. https://www.crd.york.ac.uk/PROSPERO/recorddashboard, identifier CRD420251039316.

Introduction This study aimed to evaluate the safety and preliminary efficacy of serplulimab, a novel programmed death-1 inhibitor, with or without bevacizumab biosimilar HLX04 as first-line treatment in patients with advanced hepatocellular carcinoma. Methods This open-label, multicenter phase 2 study (clinicaltrials.gov identifier NCT03973112) was conducted in China and consisted of four treatment groups: group A (serplulimab 3 mg/kg plus HLX04 5 mg/kg, subsequent-line), group B (serplulimab 3 mg/kg plus HLX04 10 mg/kg, subsequent-line), group C (serplulimab 3 mg/kg, subsequent-line) and group D (serplulimab 3 mg/kg plus HLX04 10 mg/kg, first-line). Group D was the only group in which participants received the study treatment in the first-line setting. The primary endpoint was safety. Results Following previous report on groups A and B, results of group D are herein presented. As of February 7, 2023, 61 patients were enrolled and were followed up for a median of 25.5 months. Grade ≥ 3 treatment-emergent adverse events were reported by 29 (47.5%) patients. One patient died from adverse events that were considered related to study treatment. Among the patients with at least one post-baseline tumor assessment (n = 58), the objective response rate was 29.3% (95% CI: 18.1–42.7) as assessed by an independent radiological review committee (IRRC) per RECIST v1.1. IRRC-assessed median progression-free survival was 7.3 months (95% CI: 2.8–11.0), and median overall survival was 20.4 months (95% CI: 15.0–NE), respectively. Conclusion Serplulimab combination therapy with HLX04 showed a manageable safety profile as well as preliminary efficacy in patients with advanced HCC in the first-line setting.

Background With poor prognosis and limited treatment options for advanced hepatocellular carcinoma (HCC), development of novel therapeutic agents is urgently needed. This single-arm phase I study sought to assess the safety and preliminary efficacy of icaritin in human as a potential oral immunotherapy in addition to the immune-checkpoint inhibitors. Methods Eligible advanced HCC patients with Child-Pugh Class A or B were administered with a fixed oral dose of icaritin at either 600 or 800 mg b.i.d. The primary endpoint was safety, and the secondary endpoints included time-to-progression (TTP), overall survival (OS) and the clinical benefit rate (CBR). Icaritin treatment induced immune biomarkers and immune-modulating activities in myeloid cells were also explored. Results No drug-related adverse events ≥ Grade 3 were observed in all 20 enrolled HCC patients. Among the 15 evaluable patients, 7 (46.7%) achieved clinical benefit, representing one partial response (PR, 6.7%) and 6 stable disease (SD, 40%). The median TTP was 141 days (range: 20-343 days), and the median OS was 192 days (range: 33-1036 days). Durable survival was observed in PR/SD patients with a median OS of 488 days (range: 72-773). TTP was significantly associated with the dynamic changes of peripheral neutrophils ( p  = 0.0067) and lymphocytes ( p  = 0.0337). Icaritin treatment induced changes in immune biomarkers-and immune-suppressive myeloid cells were observed. Conclusions Icaritin demonstrated safety profiles and preliminary durable survival benefits in advanced HCC patients, which were correlated with its immune-modulation activities and immune biomarkers. These results suggested the potential of icaritin as a novel oral immunotherapy for advanced HCC in addition to antibody-based PD-1/PD-L1 blockade therapies.
