Patients with unresectable hepatocellular carcinoma have a poor prognosis, and treatments with long-term benefits are needed. We report results from the preplanned interim analysis of the CheckMate 9DW trial assessing nivolumab plus ipilimumab versus lenvatinib or sorafenib for unresectable hepatocellular carcinoma in the first-line setting.

This open-label, randomised, phase 3 trial enrolled patients aged 18 years or older with unresectable hepatocellular carcinoma without previous systemic therapy at 163 hospitals and cancer centres across 25 countries in Asia, Australia, Europe, North America, and South America. Patients had at least one measurable untreated lesion per Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1, a Child-Pugh score of 5 or 6, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1) via an interactive response technology system to receive nivolumab (1 mg/kg) plus ipilimumab (3 mg/kg) intravenously every 3 weeks for up to four doses, followed by nivolumab 480 mg every 4 weeks or investigator's choice of either oral lenvatinib (8 mg or 12 mg mg daily depending on bodyweight) or oral sorafenib (400 mg twice daily). Randomisation was stratified by aetiology; the presence of macrovascular invasion, extrahepatic spread, or both; and baseline alpha-fetoprotein concentration. The primary endpoint was overall survival, which was assessed in all randomly assigned patients; safety was an exploratory endpoint and was assessed in all randomly assigned patients who received at least one dose of study medication. This trial is registered with ClinicalTrials.gov, NCT04039607 (ongoing).

Between Jan 6, 2020, and Nov 8, 2021, 668 patients were randomly assigned to nivolumab plus ipilimumab (n=335) or lenvatinib or sorafenib (n=333). Early crossing of the overall survival Kaplan-Meier curves reflected a higher number of deaths during the first 6 months after randomisation with nivolumab plus ipilimumab (hazard ratio 1·65 [95% CI 1·12-2·43]) but was followed by a sustained separation of the curves thereafter in favour of nivolumab plus ipilimumab (0·61 [0·48-0·77]). After a median follow-up of 35·2 months (IQR 31·1-39·9), overall survival was significantly improved with nivolumab plus ipilimumab versus lenvatinib or sorafenib (median 23·7 months [95% CI 18·8-29·4] vs 20·6 months [17·5-22·5]; hazard ratio 0·79 [0·65-0·96]; two-sided stratified log-rank p=0·018); respective overall survival rates were 49% (95% CI 44-55) versus 39% (34-45) at 24 months and 38% (32-43) versus 24% (19-30) at 36 months. Overall, 137 (41%) of 332 patients receiving nivolumab plus ipilimumab and 138 (42%) of 325 patients receiving lenvatinib or sorafenib had grade 3-4 treatment-related adverse events. 12 deaths were attributed to treatment with nivolumab plus ipilimumab and three were attributed to treatment with lenvatinib or sorafenib.

Nivolumab plus ipilimumab showed a significant overall survival benefit versus lenvatinib or sorafenib and manageable safety in patients with previously untreated unresectable hepatocellular carcinoma. These results support nivolumab plus ipilimumab as a first-line treatment in this setting.

To explore the efficacy and safety of RALOX-HAIC (raltitrexed plus oxaliplatin) combined with lenvatinib in the treatment of elderly patients with unresectable hepatocellular carcinoma (uHCC), aiming to provide a safer and more effective therapeutic strategy for this patient population.

A retrospective analysis was conducted on the clinical data of 82 elderly patients with uHCC who received treatment in the Department of Interventional Radiology at Wuhan Union Hospital from January 2019 to December 2022. Patients were divided into two groups based on their treatment strategy: HAIC + Lenvatinib group (N = 39) and TACE group (N = 43). The primary endpoints were the objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) in the two groups. The secondary endpoint was the incidence of treatment-related adverse events in both groups.

The ORR and DCR after treatment were higher in the HAIC + Lenvatinib group compared to the TACE group (61.5% vs. 37.2%, 82.1% vs. 58.1%, P < 0.05). The HAIC + Lenvatinib group had a longer median progression-free survival (mPFS,9.2 months vs. 4.6 months, P < 0.001) and ​median overall survival(mOS, 18.1 months vs. 10.6 months, P < 0.001) compared to the TACE group. The incidence of abdominal pain and fever was significantly higher in the TACE group than in the HAIC + Lenvatinib group (including all grades and grades 3/4, P < 0.05). The incidence of hand-foot syndrome (all grades) was higher in the HAIC + Lenvatinib group compared to the TACE group (15.4% vs. 0.0%, P = 0.009), but there was no significant difference in the incidence of grade 3/4 hand-foot syndrome between the two groups (2.6% vs. 0.0%, P = 0.476).

This study demonstrates that RALOX-HAIC combined with lenvatinib provides superior survival outcomes and tolerability compared to TACE alone ​in elderly patients (≥ 70 years) with unresectable HCC. This combination therapy may be a feasible and safe option for improving the prognosis of elderly patients with uHCC.

Advanced hepatocellular carcinoma (HCC) is characterized by poor prognosis, primarily due to limited therapeutic options and resistance to treatment. Although the combination of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) has shown promising potential, the underlying mechanisms remain inadequately understood. Here, serine/threonine-specific protein phosphatase (PP1A) is upregulated in Lenvatinib-resistant HCC cells and correlates with poor prognosis. Functional experiments revealed that PP1A promotes HCC progression both in vitro and in vivo. Transcriptomic analysis and ferroptosis metabolite profiling (e.g., ROS, Fe2⁺, lipid-ROS, and GSH) demonstrated that PP1A inhibits Lenvatinib-induced ferroptosis by dephosphorylating Keap1 at site 104. This disruption of the Keap1-Nrf2 interaction enhances the transcription of ferroptosis-related markers and immune checkpoint PD-L1. Notably, single-cell sequencing and co-culture experiments revealed that PP1A knockdown alleviates T cell exhaustion and immune evasion, thereby improving antitumor immunity. In vivo experiments further demonstrated that PP1A knockdown significantly enhances the efficacy of Lenvatinib-ICIs combination therapy. Overall, our findings highlight PP1A as a critical regulator of ferroptosis and antitumor immunity, suggesting its potential as a predictive biomarker and therapeutic target for improving outcomes in advanced HCC.

Side effects from tyrosine kinase inhibitors (TKIs) are common and burdensome. Olanzapine is useful for managing symptoms from conventional chemotherapy, but its role in treating TKI-related side effects is unclear.

Examine the efficacy of olanzapine for TKI-induced nausea, vomiting, anorexia, weight loss, and insomnia.

All patients prescribed olanzapine with lenvatinib, cabozantinib, axitinib, or tivozanib at Mayo Clinic between January 2018 and June 2024 were assessed for inclusion. For baseline assessment, clinical notes documenting symptoms and indication(s) for starting olanzapine were reviewed. Notes and portal messages from the first three months after starting olanzapine were then evaluated for qualitative descriptions of change in symptom burden. Data were categorized as "improved," "worsened," "stable," or "missing data," with each symptom domain analyzed independently, when olanzapine was prescribed for multiple interrelated symptoms.

Sixty patients received olanzapine, most commonly 5 mg (n = 37, 61.7%) or 2.5 mg (n = 16, 26.6%). Indications included nausea without vomiting (n = 35), anorexia (n = 25), nausea with vomiting (n = 16), weight loss (n = 16), and insomnia (n = 11). It was given for multiple symptoms in 32 patients. Within the first 3 months, 85% of patients had improvement in nausea without vomiting, 93% in nausea with vomiting, 74% in appetite, and 85% in sleep. Among 34 patients with weight loss prior to olanzapine, 50% gained weight (median: 6.1 kg), 26% stabilized (±1 kg), and 24% continued to lose weight. Only 4 patients discontinued olanzapine due to side effects.

Olanzapine appears effective in treating TKI-induced nausea, vomiting, anorexia, insomnia, and weight loss, warranting further investigation in prospective studies.

The efficacy of atezolizumab-bevacizumab in patients with hepatocellular carcinoma (HCC) has not been studied separately in cirrhotic and non-cirrhotic patients. Our aim was to evaluate the efficacy of atezolizumab-bevacizumab in these patients, in relation to baseline values of the neutrophil-to-lymphocyte ratio (NLR).

We divided 57 atezolizumab-bevacizumab-treated HCC patients according to baseline NLR (>3: NLR-H, ≤3: NLR-L) and studied overall survival (OS) and progression-free survival (PFS) in 4 groups: group A, non-cirrhotic/NLR-L; group B, non-cirrhotic/NLR-H; group C, cirrhotic/NLR-L; and group D, cirrhotic/NLR-H.

The 4 groups were comparable except for etiology, ALBI grade, macrovascular invasion, Barcelona Clinic Liver Cancer stage and prior therapy. Median OS and PFS were 30, 10, 12 and 5 months, and 14, 4, 8 and 2 months, for groups A, B, C, D, respectively (P<0.001). By Cox regression, cirrhotic/NLR-H patients showed significantly worse OS and PFS. Cirrhotic/NLR-L patients had better OS (12 vs. 5 months, P=0.002) and PFS (8 vs. 2 months, P=0.028) compared to cirrhotic/NLR-H. NLR was significantly correlated with OS (P=0.015). Non-cirrhotic/NLR-L patients had better OS (30 vs. 10 months, P=0.006) and PFS (15 vs. 4 months, P=0.01) compared to non-cirrhotic/NLR-H patients. Prior therapy was significantly correlated with better OS (30 vs. 8 months, P<0.001) and PFS (24 vs. 4 months, P<0.001) in non-cirrhotic patients.

Cirrhotic/NLR-H HCC patients presented the worst survival. NLR is an independent risk factor for worse survival in cirrhotic patients. Prior therapy is the only factor significantly correlated with OS and PFS in non-cirrhotic patients.

The recent introduction of the term metabolic-dysfunction-associated steatotic liver disease (MASLD) has highlighted the critical role of metabolism in the disease's pathophysiology. This innovative nomenclature signifies a shift from the previous designation of non-alcoholic fatty liver disease (NAFLD), emphasizing the condition's progressive nature. Simultaneously, MASLD has become one of the most prevalent liver diseases worldwide, highlighting the urgent need for research to elucidate its etiology and develop effective treatment strategies. This review examines and delineates the revised definition of MASLD, exploring its epidemiology and the pathological changes occurring at various stages of the disease. Additionally, it identifies metabolically relevant targets within MASLD and provides a summary of the latest metabolically targeted drugs under development, including those in clinical and some preclinical stages. The review finishes with a look ahead to the future of targeted therapy for MASLD, with the goal of summarizing and providing fresh ideas and insights.

The gut microbiota is often altered in chronic liver diseases and hepatocellular carcinoma (HCC), and increasing evidence suggests that it may influence response to cancer immunotherapy. Strategies to modulate the gut microbiome (i.e., fecal microbiota transplant (FMT)) may help to improve efficacy of immune checkpoint inhibitors (ICIs) or even overcome resistance to ICIs. Here, we describe the design and rationale of FAB-HCC, a single-center, single-arm, phase II pilot study to assess safety, feasibility, and efficacy of FMT from patients with HCC who responded to PD-(L)1-based immunotherapy or from healthy donors to patients with HCC who failed to achieve or maintain a response to atezolizumab plus bevacizumab.

In this single-center, single-arm, phase II pilot study (ClinicalTrials.gov identifier: NCT05750030), we plan to include 12 patients with advanced HCC who failed to achieve or maintain a response to atezolizumab/bevacizumab. Patients will receive a single FMT via colonoscopy from donors with HCC who responded to PD-(L)1-based immunotherapy or from healthy individuals, followed by atezolizumab/bevacizumab every 3 weeks. The primary endpoint is safety, measured by incidence and severity of treatment-related adverse events. The main secondary endpoint is efficacy, as assessed by best radiological response according to RECISTv1.1 and mRECIST. Additional exploratory endpoints include data on the effect of FMT on recipient gut microbiota, as well as metagenomic analysis of stool samples, analyses of circulating immune cells and serum and stool proteomic, metabolomic and lipidomic signatures.

The results of this study will help to define the potential of FMT as add-on intervention in the systemic treatment of advanced HCC, with the potential to improve efficacy of immunotherapy or even overcome resistance.

Hepatocellular carcinoma (HCC) remains a major global health concern, as it is the most common primary liver cancer and the fourth leading cause of cancer-related mortality.

Immune checkpoint inhibitors (ICIs) have significantly shifted the treatment paradigm, offering promising survival outcomes. However, the controlled conditions of randomized clinical trials (RCTs) often fail to reflect real-world complexities, emphasizing the necessity for strong real-world evidence (RWE). RWE, in most cases derived from observational studies, provides critical insights into the effectiveness, safety, and tolerability of systemic therapies across diverse populations and settings. The authors searched MEDLINE, Ovid Embase, and Scopus for full-text published articles in any language from the inception to 30 June 2024.This review evaluates RWE on systemic therapies for advanced HCC, including tyrosine kinase inhibitors (TKIs) like sorafenib and lenvatinib, ICIs such as nivolumab and pembrolizumab, and combination therapies like atezolizumab/bevacizumab and durvalumab/tremelimumab.

Studies reveal discrepancies in treatment efficacy and adverse event profiles between RCTs and routine clinical practice, underscoring the need for individualized treatment strategies. RWE highlights the influence of liver disease etiology, liver function, and tumor burden on treatment outcomes, guiding therapy selection.

Hepatocellular carcinoma (HCC) is a primary liver cancer often associated with chronic liver disease and characterized by multifocal tumor lesions with synchronous and metachronous lesions, which poses treatment challenges due to potential genomic heterogeneity. This study aims to assess the consistency of actionable mutation profiles across synchronous and metachronous lesions in HCC patients.

This study analyzed 68 patients with multifocal HCC, including 193 tumor lesions (82 synchronous, 111 metachronous). Genomic profiling of 72 HCC-related genes was performed using next-generation sequencing. We collected clinical and pathological data, including tumor size, grade, fibrosis, and etiology. Patients were categorized into two groups based on the consistency of actionable mutations among multifocal HCC. Statistical analyses compared clinicopathological features between these groups.

A total of 252 and 445 somatic mutations were identified in synchronous and metachronous tumors, respectively. Synchronous tumors had an average of 3.1 somatic mutations and 0.7 actionable mutations per lesion. Metachronous tumors had 4.0 somatic mutations and 1.0 actionable mutations per lesion. Actionable variants were found in 12 (36.4%) of 33 patients and 20 (24.4%) of 82 nodules in the synchronous tumors, and 23 (65.7%) of 35 patients and 42 (37.8%) of 111 nodules in the metachronous tumors. Compared to synchronous tumors, metachronous tumors exhibited significantly aberrant signaling pathways including the Wnt/β-catenin (p = 0.009) and KEAP1/NRF2 (p = 0.022) pathways. There was no correlation with significant clinical differences in tumor characteristics between the consistent and divergent actionable mutation groups. Notably, divergent actionable mutations were identified in 45.6% of patients, which may be beneficial for changing potential therapies for individual tumors.

The study shows substantial inter-tumoral heterogeneity in multifocal HCC, indicating the necessity for comprehensive molecular profiling for tailored treatment strategies. Divergent actionable mutations across lesions suggest that a uniform treatment approach may not be effective in some patients with multifocal HCC.

Lenvatinib is a tyrosine kinase inhibitor that effectively inhibits vascular endothelial growth factor signaling and is used for treating hepatocellular carcinoma. However, angiogenesis inhibitors often cause hypertension. Although lenvatinib-induced hypertension has been proposed as a potential surrogate marker for better prognosis, studies on blood pressure elevations and outcomes following lenvatinib initiation are limited. This study included 67 patients who underwent lenvatinib therapy at the Department of Gastroenterology, Kagoshima University Hospital, between May 2018 and December 2023. The median age of the cohort was 71 years, and 82.1% of the patients were male. The median blood pressure at admission was 128/73 mmHg, which significantly increased to 136/76 mmHg the day after lenvatinib administration. Grade 3 hypertension (≥160/100 mmHg) occurred in 37.3% of patients during hospitalization. The median increase in systolic blood pressure from admission to its peak during hospitalization was 26 mmHg. Patients who experienced an increase in blood pressure of ≥26 mmHg were classified into the blood pressure elevation group, which showed a significantly lower mortality rate than that of the blood pressure non-elevation group (35.3% vs. 81.8%, log-rank p = 0.007), even after adjusting for age, sex, disease stage, performance status, and liver reserve function. This study demonstrated that patients who experienced earlier blood pressure elevation after lenvatinib administration had lower overall mortality rates. These findings suggest that blood pressure elevations after lenvatinib initiation may serve as valuable prognostic indicators in patients with cancer undergoing lenvatinib therapy. • Early Blood Pressure Elevation Following Lenvatinib Administration Significant blood pressure elevation was observed from the day after Lenvatinib administration, with a median systolic blood pressure increase of 26 mmHg. Grade 3 hypertension (≥160/100 mmHg) was observed in 38% of patients during hospitalization. •Blood Pressure Control Antihypertensive therapy was intensified in 39% of patients during hospitalization, yet 12% still had Grade 3 hypertension the day before discharge. • Association Between Blood Pressure Elevation and Prognosis Even after adjusting for age, sex, disease stage, performance status, and liver function reserve, blood pressure elevation was suggested as a better prognostic factor.

Ripretinib has been approved for the treatment of gastrointestinal stromal tumors (GIST). As a novel therapy, several adverse reactions remain unidentified, necessitating a thorough safety evaluation. This study analyzes real-world data from the US Food and Drug Administration Adverse Event Reporting System (FAERS) to investigate adverse events (AEs) associated with ripretinib.

Adverse event reports (AERs) related to ripretinib were extracted from FAERS ASCII data spanning from the second quarter of 2020 to the second quarter of 2024. Following standardization, various disproportionality analyses, including the reporting odds ratio (ROR), proportional reporting ratio (PRR), bayesian confidence propagation neural network (BCPNN), and empirical bayes geometric mean (EBGM), were employed to identify potential safety signals linked to ripretinib. The data provided by medical professionals underwent sensitivity analysis to assess the robustness of the results.

A total of 3,105 ripretinib-related AERs were identified, categorized into 22 system organ classes (SOCs) and 84 preferred terms (PTs). Common AEs, such as alopecia, constipation, and muscle spasms, were consistent with the drug label and clinical trial findings. Notably, the risk of skin cancer associated with ripretinib was further elucidated. Additionally, new signals, including liver abscess and prostatomegaly, were detected. Despite their lower frequency, these signals demonstrated significant strength. A substantial proportion of adverse reactions (n = 322, 39.80%) occurred within the first month of treatment, although a smaller fraction emerged after one year. The sensitivity analysis revealed that most PTs related to skin and subcutaneous tissue maintained high signal values, with 8 cases of skin squamous cell carcinoma-related AEs still reported.

The findings of this study align with established drug guidance and uncover new adverse event signals for ripretinib, thereby enhancing clinical monitoring and facilitating risk identification.

Recent advances in systemic therapy for hepatocellular carcinoma are remarkable. The treatment goal for advanced hepatocellular carcinoma is to prolong survival, while for intermediate-stage hepatocellular carcinoma, it is to achieve a cancer-free and drug-free status. Patients unsuitable for transarterial chemoembolization may benefit from prior systemic therapy with lenvatinib or atezolizumab plus bevacizumab. The TACTICS-L trial, a prospective phase II trial, demonstrated favorable progression-free and overall survival by lenvatinib-transarterial chemoembolization sequential therapy. The REPLACEMENT trial, a multicenter, prospective, single-arm phase II trial, confirmed combination immunotherapy efficacy with atezolizumab plus bevacizumabin a population exceeding up-to-seven criteria. In a proof-of-concept study, atezolizumab plus bevacizumab plus curative therapy showed a 35% complete response rate and 23% drug-free status in intermediate-stage hepatocellular carcinoma patients with a tumor burden exceeding up-to-seven criteria.

Recent advances in the systemic treatment of advanced hepatocellular carcinoma (HCC) with immunotherapy have once again reignited discussion over the role of combined therapy in earlier stages. This year, different international meetings have presented recent results from clinical trials on adjuvant therapy alone (IMBrave-050) and combined with transarterial chemoembolization (EMERALD-1 and LEAP-12). Increased enthusiasm for the use of adjuvant and neoadjuvant therapy for liver transplantation, surgery, and local-regional treatment of HCC has been shown. However, the initial results from these trials should be interpreted cautiously as we wait for final analyses and effects on overall survival. In this position paper from the special interest group from the Latin American Association for the Study of Liver Diseases (ALEH), we underline the caveats of the applicability of these potential treatments in our region, explore points of agreement, and highlight areas of uncertainty. Moreover, we underscore the role of hepatologists in the clinical decision-making process and management of these patients.

Epigenetic reprogramming and escape from terminal differentiation are poorly understood enabling characteristics of liver cancer. Keratin 19 (KRT19), classically known to form the intermediate filament cytoskeleton, is a marker of stemness and worse prognosis in liver cancer. This study aimed to address the functional roles of KRT19 in liver tumorigenesis and to elucidate the underlying mechanisms.

Using multiplexed genome editing of hepatocytes in vivo, we demonstrated that KRT19 promoted liver tumorigenesis in mice. Cell fractionation revealed a previously unrecognized nuclear fraction of KRT19. Tandem affinity purification identified histone deacetylase 1 and REST corepressor 1, components of the corepressor of RE-1 silencing transcription factor (CoREST) complex as KRT19-interacting proteins. KRT19 knockout markedly enhanced histone acetylation levels. Mechanistically, KRT19 promotes CoREST complex formation by enhancing histone deacetylase 1 and REST corepressor 1 interaction, thus increasing the deacetylase activity. ChIP-seq revealed hepatocyte-specific genes, such as hepatocyte nuclear factor 4 alpha ( HNF4A ), as direct targets of KRT19-CoREST. In addition, we identified forkhead box P4 as a direct activator of aberrant KRT19 expression in liver cancer. Furthermore, treatment of primary liver tumors and patient-derived xenografts in mice suggest that KRT19 expression has the potential to predict response to histone deacetylase 1 inhibitors especially in combination with lenvatinib.

Our data show that nuclear KRT19 acts as a transcriptional corepressor through promoting the deacetylase activity of the CoREST complex, resulting in dedifferentiation of liver cancer. These findings reveal a previously unrecognized function of KRT19 in directly shaping the epigenetic landscape in cancer.

Lenvatinib is a molecular-targeted agent with proven efficacy against hepatocellular carcinoma (HCC). We herein report a case of lenvatinib-associated Fournier gangrene. A 66-year-old man with advanced HCC presented with a high fever 4 weeks after switching to lenvatinib. He had severe erythema in the inguinal region, and abdominal computed tomography revealed extensive emphysema and scrotal abscesses. He was diagnosed with Fournier's gangrene, and his symptoms were successfully treated with local debridement and antimicrobial therapy. Although reports of lenvatinib-associated Fournier's gangrene are rare, they should be kept in mind, as the condition could progress rapidly and have poor outcomes.

The incidence and mortality rates of liver cancer in China remain elevated. Although early-stage liver cancer is amenable to surgical resection, a significant proportion of patients are diagnosed at advanced stages. Currently, in addition to surgical resection for hepatocellular carcinoma, the primary treatment modalities predominantly include chemotherapy. The widespread use of chemotherapy, which non-selectively targets both malignant and healthy cells, often results in substantial immunosuppression. Simultaneously, the accumulation of chemotherapeutic agents can readily induce drug resistance upon reaching the physiological threshold, thereby diminishing the efficacy of these treatments. Besides chemotherapy, there exist targeted therapy, immunotherapy and other therapeutic approaches. Nevertheless, the development of drug resistance remains an inevitable challenge. To address these challenges, we turn to nanomedicine, an emerging and widely utilized discipline that significantly influences medical imaging, antimicrobial strategies, drug delivery systems, and other related areas. Stable and safe nanomaterials serve as effective carriers for delivering anticancer drugs. They enhance the precision of drug targeting, improve bioavailability, and minimize damage to healthy cells. This review focuses on common nanomaterial carriers used in hepatocellular carcinoma (HCC) treatment over the past five years. The following is a summary of the three drugs: Sorafenib, Gefitinib, and lenvatinib. Each drug employs distinct nanomaterial delivery systems, which result in varying levels of bioavailability, drug release rates, and therapeutic efficacy.

Hand-foot-skin reaction (HFSR) is the most common side effect of multi-tyrosine kinase inhibitor therapy for unresectable hepatocellular carcinoma (uHCC). Sarcopenia has been reported to be a poor prognostic factor for HCC. Here, we performed a randomized controlled trial (RCT) of the efficacy of a β-hydroxy-β-methyl butyrate/l-arginine/l-glutamine (HMB/Arg/Gln) beverage and locomotion training as supportive care in the treatment of uHCC with lenvatinib.

A total of 20 patients were enrolled from the jRCTs031190252 trial in this pilot study. HFSR was the primary endpoint, and other adverse events and skeletal muscle index at the third lumbar level (L3-SMI) were secondary endpoints.

Twelve patients had albumin-bilirubin grade 1, and eight had grade 2. No difference in HFSR was observed. Although interesting differences were observed in the secondary endpoints, a slight retention of L3-SMI values in the intervention group compared with that in the control group was observed (96.5 % vs. 89.9 %, p = 0.407).

Although the HMB/Arg/Gln beverage and locomotion training did not reduce adverse events caused by lenvatinib, they might be useful in maintaining skeletal muscle mass. Further validation studies with a larger number of patients are warranted.

The real-world survival of patients with unresectable hepatocellular carcinoma (uHCC) treated with lenvatinib has been explored retrospectively with a small sample size. We conducted a prospective observational 2-year extension study (510 study) of a 1-year observational post-marketing study of lenvatinib (504 study) to evaluate the long-term overall survival (OS) of patients with uHCC treated with lenvatinib and associated factors with a large sample size.

Patients with uHCC included (July 2018 to January 2019) in the 504 study and who consented were eligible for the 510 study and were followed for up to 3 years after lenvatinib treatment initiation. Using the data from the 504 study and 510 study of the 504 study analysis set, we estimated the OS, the time from the first lenvatinib dose to all-cause death by the Kaplan-Meier method (ClinicalTrials.Gov Registration ID, 504 study: NCT03663114; 510 study: NCT04008082).

The 703 patients included in the analysis were followed for a median period (min, max) of 12.5 months (0.1, 44.8). The median OS (95% confidence interval) was 16.6 months (15.4, 18.5). OS was significantly (p < 0.05) associated with bile duct invasion (hazard ratio [HR]: 1.621), portal vein invasion (HR: 1.365), ≥ 4 intrahepatic lesions (HR: 1.437), extrahepatic lesions (HR: 1.357), Child-Pugh B/C (HR: 1.515), mALBI Grade 2a (HR: 1.331), and Grade ≥ 2b (HR: 1.811).

This large-scale, prospective, real-world study demonstrated a long OS, comparable to that reported in the global Phase III REFLECT trial. More advanced-stage tumors and worse hepatic function have been suggested as OS-associated factors, consistent with previous reports.

Recently, a systemic therapy for advanced hepatocellular carcinoma (HCC) has been developed. The regimen for unresectable HCC varies and includes single or multi-tyrosine kinase inhibitors, monoclonal antibodies, immune checkpoint inhibitors, or their combinations. Treatment with these agents begins with sorafenib as the first-line drug for unresectable HCC. Subsequently, several systemic therapies, including lenvatinib, ramucirumab, cabozantinib, and regorafenib have been investigated and established. With advances in systemic therapy for unresectable HCC, the prognosis of patients with unresectable HCC has improved significantly than previously. Conversion surgery, consisting of systemic therapy and surgery, showed the possibility of improving the prognosis than systemic therapy alone. Although a combination of atezolizumab and bevacizumab is mostly used for initially unresectable HCC to conduct conversion surgery because of the high response rate and fewer adverse events compared to others, many trials are being conducted to assess their efficacy for initially unresectable HCC. However, the appropriate timing of surgery and interval between systemic therapy and surgery remain controversial. To address these issues, a multidisciplinary team can play a vital role in determining the strategies for treating unresectable HCC. This review describes previous and current trends in the treatment of HCC, with a particular focus on conversion surgery for initially unresectable HCC.

Subcutaneous metastasis of endometrial cancer (EC) is an exceedingly rare phenomenon, and the mechanisms underlying its pathogenesis remain insufficiently elucidated. We report the case of a 69-year-old multiparous woman diagnosed with stage IB EC, histologically classified as grade 3 endometrioid and clear cell carcinoma. Approximately one month following primary surgical intervention, the patient developed subcutaneous masses on her back, axilla, and buttock. Histopathological evaluation, in conjunction with PET-CT, confirmed a systemic recurrence of EC. She was subsequently treated with a combination of paclitaxel and carboplatin, with a remarkable therapeutic response; after six cycles of chemotherapy, nearly all metastatic sites exhibited complete resolution. She was then transitioned to a regimen of lenvatinib and pembrolizumab. However, one week after the initiation of this treatment, she developed hepatic encephalopathy, which was presumed to be lenvatinib-induced, and was successfully managed with aminoleban injections, resulting in a full recovery of consciousness. Follow-up diagnostic imaging confirmed a complete response to therapy. The patient is currently receiving pembrolizumab as maintenance therapy and has remained recurrence-free for 18 months. While no standardized therapeutic protocol exists for the management of subcutaneous metastasis in EC due to its extremely low incidence, this report provides evidence for the potential efficacy of chemotherapy combined with targeted immunotherapy in the treatment of unresectable subcutaneous metastases in EC.

Lenvatinib is a multi-target tyrosine kinase inhibitor widely used in the treatment of hepatocellular carcinoma (HCC). Its primary mechanism of action involves inhibiting signal pathways such as vascular endothelial growth factor receptors (VEGFR) and fibroblast growth factor receptors (FGFR), thereby reducing tumor cell proliferation and angiogenesis and affecting the tumor's immune microenvironment. In the treatment of liver cancer, although lenvatinib monotherapy has shown good clinical effect, the problem of drug resistance is becoming more and more serious. This resistance may be caused by a variety of factors, including genetic mutations, signaling pathway remodeling, and changes in the tumor microenvironment. In order to overcome drug resistance, the combination of lenvatinib and other therapeutic strategies has gradually become a research hotspot, and it is worth noting that the combination of lenvatinib and immune checkpoint inhibitors (ICIs) has shown a good application prospect. This combination not only enhances the anti-tumor immune response but also helps improve therapeutic efficacy. However, combination therapy also faces challenges regarding safety and tolerability. Therefore, studying the mechanisms of resistance and identifying relevant biomarkers is particularly important, as it aids in early diagnosis and personalized treatment. This article reviews the mechanisms of lenvatinib in treating liver cancer, the mechanisms and efficacy of its combination with immune checkpoint inhibitors, the causes of resistance, the exploration of biomarkers, and other novel combination therapy strategies for lenvatinib. We hope to provide insights into the use and research of lenvatinib in clinical and scientific settings, offering new strategies for the treatment of liver cancer.

Hepatocellular carcinoma (HCC) is one of the most common forms of primary liver cancer worldwide. Herein, we present a review article that provides a broad overview of the current landscape of HCC, including the etiology, potential risk factors, and molecular pathways that can serve as potential therapeutic targets. The risk factors tend to vary depending on the geographic distribution; hepatitis B-induced cirrhosis and HCC occur more frequently in Asia and Sub-Saharan Africa, whereas metabolic disorders are the culprits in Western Europe and the Americas. The exact molecular alterations that drive hepatocarcinogenesis have yet to be elucidated; however, a complex interplay exists between oxidative stress and chronic inflammation. Diagnostic modalities such as tri-phasic MRI or CT also have distinct patterns for HCC, which aid significantly in diagnosis. Furthermore, the review aims to highlight treatment strategies, including transplantation, locoregional radiation therapies, and interventional radiological techniques such as chemotherapy or radioembolization. Finally, systemic therapies will be discussed, taking advantage of molecular pathways that influence cellular proliferation and survival as well as immunotherapy.

The aim of this study was to investigate the efficacy and safety of the combined treatment regimen of D-TACE, HAIC, and Lenvatinib in patients with massive hepatocellular carcinoma, with the goal of providing a safer and more effective therapeutic strategy for individuals suffering from massive hepatocellular carcinoma.

A retrospective analysis was conducted using clinical data from 118 patients with unresectable massive hepatocellular carcinoma who underwent treatment at the Interventional Department of Wuhan Union Hospital between June 2018 and December 2021. Based on the treatment approach, the patients were divided into two groups: the D-TACE + HAIC + Lenvatinib group (N = 54) and the D-TACE + Lenvatinib group (N = 64). The primary study endpoints included the objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) of the two groups. Additionally, the occurrence of treatment-related adverse events in both groups was considered as a secondary study endpoint.

Following the treatment, the D-TACE + HAIC + Lenvatinib group exhibited significantly higher ORR and DCR compared to the D-TACE + Lenvatinib group (68.5% vs. 43.8%, 90.7% vs. 73.4%, P < 0.05). Moreover, the D-TACE + HAIC + Lenvatinib group demonstrated longer mPFS and mOS in comparison to the D-TACE + Lenvatinib group (8.6 months vs. 6.6 months, P = 0.005; 19.5 months vs. 14.1 months, P < 0.001). There was no statistically significant difference in the occurrence rate of common treatment-related adverse events between the TACE + HAIC + Lenvatinib group and the D-TACE + Lenvatinib group (P > 0.05).

The combined treatment regimen of D-TACE, HAIC, and Lenvatinib demonstrated superior therapeutic efficacy and safety in managing unresectable massive hepatocellular carcinoma. This combination therapy may serve as a viable option for improving the prognosis of patients with unresectable massive hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) represents a major public health concern and ranks among the leading cancer-related mortalities globally. Due to the frequent late-stage diagnosis of HCC, therapeutic options remain limited. Emerging evidence highlights the critical role of non-coding RNAs (ncRNAs) in the regulation of Aurora kinase A (AURKA), one of the key hub genes involved in several key cancer pathways. Indeed, the dysregulated interaction between ncRNAs and AURKA contributes to tumor development, progression, and therapeutic resistance. This review delves into the interplay between ncRNAs and AURKA and their role in hepatocarcinogenesis. Recent findings underscore the involvement of the ncRNAs and AURKA axis in tumor development and progression. Furthermore, this review also discusses the clinical significance of targeting ncRNA-AURKA axes, offering new perspectives that could lead to innovative therapeutic strategies aimed at improving outcomes for HCC patients.

The integration of transarterial chemoembolization (TACE) with systemic therapy has demonstrated improved survival outcomes in patients with unresectable hepatocellular carcinoma (HCC). However, there is limited evidence evaluating the combination of TACE with the systemic regimen of anti-PD-1/L1 inhibitor plus lenvatinib. This study aims to assess the efficacy and safety of TACE combined with lenvatinib and sintilimab in unresectable HCC patients.

Unresectable HCC patients who received TACE in combination with sintilimab plus Lenvatinib as first-line treatment from 1 January 2020 to 31 March 2023 were included for the analysis. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR) were evaluated by modified Response Evaluation Criteria in Solid Tumors criteria. Exploratory biomarker analysis was conducted.

The study included 70 patients with unresectable HCC, predominantly male and infected with Hepatitis B. The median follow-up duration for the whole cohort was 13.8 months (95% CI 11.08-16.7). The ORR was 61.4% (95% CI, 49.0%-72.8%) and the DCR was 68.6% (95%CI, 56.4%-79.2%). The median PFS was 13.2 months (95% CI 11.0-NA), with a corresponding 1-year PFS rate of 50.3% (95% CI 39.7%-65.5%). The median OS was not reached, and the 1-year OS rate was 89.3% (95% CI 81.4%-97.9%). The most common treatment-related adverse events (TRAEs) were fatigue 38.6% (27/70), hypertension 32.9% (23/70), and hand-foot syndrome 31.4% (22/70). Most TRAEs were mild-to-moderate and manageable. In addition, significant predictive value was found in alpha-fetoprotein levels (AFP), with patients showing a level of decrease post-treatment having better PFS.

The combination regimen demonstrated promising efficacy in treating unresectable HCC, accompanied by manageable safety profiles. Furthermore, the results of this investigation suggest that AFP holds promise as predictive biomarkers for this treatment strategy.

Autoimmune liver diseases (AILD) are rare causes hepatocellular carcinoma (HCC), and data on the efficacy and tolerability of anti-tumor therapies are scarce. This pan-European study aimed to assess outcomes in AILD-HCC patients treated with tyrosine kinase inhibitors (TKIs) or transarterial chemoembolization (TACE) compared with patients with more common HCC etiologies, including viral, alcoholic or non-alcoholic fatty liver disease.

107 patients with HCC-AILD (AIH:55; PBC:52) treated at 13 European centres between 1996 and 2020 were included. 65 received TACE and 28 received TKI therapy. 43 (66 %) were female (median age 73 years) with HCC tumor stage BCLC A (34 %), B (46 %), C (9 %) or D (11 %). For each treatment type, propensity score matching was used to match AILD to non-AILD-HCC on a 1:1 basis, yielding in a final cohort of 130 TACE and 56 TKI patients for comparative analyses of median overall survival (mOS) and treatment tolerability.

HCC-AILD patients showed comparable mOS to controls for both TACE (19.5 vs. 22.1 months, p = 0.9) and TKI (15.4 vs. 15.1 months, p = 0.5). Adverse events were less frequent in AILD-HCC patients than controls (33 % % vs. 62 %, p = 0.003). For TKIs, there were no significant differences in adverse events (73% vs. 86%, p = 0.2) or interruption rates (44% vs. 36 %, p = 0.7).

In summary, this study demonstrates comparable mOS for AILD-HCC patients undergoing local and systemic treatments, with better tolerability than HCC of other causes. TKIs remain important therapeutic options for AILD-HCC patients, particularly given their exclusion from recent immunotherapy trials.

Liver cancer is one of the most prevalent malignant tumors worldwide. According to the Barcelona Clinic Liver Cancer staging criteria, clinical guidelines provide tutorials to clinical management of liver cancer at their individual stages. However, most patients diagnosed with liver cancer are at advanced stage; therefore, many researchers conduct investigations on targeted therapy, aiming to improve the overall survival of these patients. To date, small-molecule-based targeted therapies are highly recommended (first line: sorafenib and lenvatinib; second line: regorafenib and cabozantinib) by current the clinical guidelines of the American Society of Clinical Oncology, European Society for Medical Oncology, and National Comprehensive Cancer Network. Herein, we summarize the small-molecule-based targeted therapies in liver cancer, including the approved and preclinical therapies as well as the therapies under clinical trials, and introduce their history of discovery, clinical trials, indications, and molecular mechanisms. For drug resistance, the revealed mechanisms of action and the combination therapies are also discussed. In fact, the known small-molecule-based therapies still have limited clinical benefits to liver cancer patients. Therefore, we analyze the current status and give our ideas for the urgent issues and future directions in this field, suggesting clues for novel techniques in liver cancer treatment.

This study aimed to assess the effect of adjuvant therapy with different durations in patients with initially unresectable hepatocellular carcinoma (uHCC) after conversion surgery.

This study included 85 patients with initially uHCC who received conversion surgery between May 2019 and November 2022. They were divided into the long duration group (n = 57) and short duration group (n = 28) based on postoperative medication duration. Recurrence-free survival (RFS) and overall survival (OS) were analyzed and compared between the cohorts.

No significant difference in RFS or OS was found between the two groups [RFS: hazard ratio (HR) = 0.486; 95% confidence interval (CI), 0.229-1.034, P = 0.061; OS: HR = 0.377; 95% CI, 0.119-1.196, P = 0.098]. Patients without major pathologic response (MPR) in the long duration group had better RFS and OS results compared to those in the short duration group (RFS: HR = 0.242; 95% CI, 0.092-0.634, P = 0.004; OS: HR = 0.264; 95% CI, 0.079-0.882, P = 0.031). No significant difference was detected in RFS or OS between the two groups in patients with MPR (RFS: HR = 1.250; 95% CI, 0.373-4.183, P = 0.718; OS: HR = 7.389; 95% CI, 0.147-372.4, P = 0.317). After propensity score matching, 25 pairs of patients were selected and the results remained consistent.

At least 6 months of adjuvant therapy may be beneficial for patients without MPR after conversion surgery. However, in patients with MPR, the effect of adjuvant therapy remains unclear. Further studies are needed to confirm the optimal duration of adjuvant therapy.

The efficacy of systemic therapy for unresectable advanced hepatocellular carcinoma (aHCC) has not been proven in patients with Child-Pugh (C-P) B cirrhosis. Nevertheless, in real-world these patients are treated both with tyrosine kinase inhibitors (TKIs) and with metronomic capecitabine (MC). This study aimed to compare sorafenib and MC outcomes versus best supportive care (BSC) in C-P B patients.

Between 2008 and 2020, among 774 C-P B patients with aHCC not amenable/responsive to locoregional treatments, 410 underwent sorafenib, 62 MC, and 302 BSC. The propensity score matching method was used to correct the baseline unbalanced prognostic factors.

In the unmatched population, median OS was 9.7 months in patients treated with sorafenib, 8.0 with MC, and 3.9 months with BSC. In sorafenib vs. BSC-matched patients (135 couples), median OS was 7.3 (4.9-9.6) vs. 3.9 (2.6-5.2) months (p<0.001). ECOG-Performance Status, tumor size, macrovascular invasion, AFP, treatment-naive, and sorafenib were independent predictors of survival. In MC vs. BSC-matched patients (40 couples), median OS was 9.0 (0.2-17.8) vs.3.0 (2.2-3.8) months (p<0.001). Median OS did not differ (p = 0.283) in sorafenib vs. MC-matched patients (55 couples).

C-P B patients with aHCC undergoing BSC have poor survival. Both Sorafenib and MC treatment improve their prognosis.

Systemic therapy is the current standard treatment for hepatocellular carcinoma (HCC) with extrahepatic metastasis (EHM). However, some patients with HCC and EHM undergo transarterial chemoembolization (TACE) to manage intrahepatic tumors. Herein, we aimed to explore the appropriateness of TACE in patients with HCC and EHM in an era of advanced systemic therapy.

This study analyzed 248 consecutive patients with HCC and EHM (median age, 58.5 years; male, 83.5%; Child-Pugh A, 88.7%) who received TACE or systemic therapy (83 sorafenib, 49 lenvatinib, 28 immunotherapy-based) between January 2018 and January 2021.

Among the patients, 196 deaths were recorded during a median follow-up of 8.9 months. Patients who received systemic therapy had a higher albumin-bilirubin grade, elevated tumor markers, an increased number of intrahepatic tumors, larger-sized tumors, and more frequent portal vein invasion than those who underwent TACE. TACE was associated with longer median overall survival (OS) than sorafenib (15.1 vs. 4.7 months; 95% confidence interval [CI], 11.1-22.2 vs. 3.7-7.3; hazard ratio [HR], 1.97; P<0.001). After adjustment for potential confounders, TACE was associated with statistically similar survival outcomes to those of lenvatinib (median OS, 8.0 months; 95% CI, 6.5-11.0; HR, 1.21; P=0.411) and immunotherapies (median OS, 14.3 months; 95% CI, 9.5-27.0; HR, 1.01; P=0.973), demonstrating survival benefits equivalent to these treatments.

In patients with HCC and EHM, TACE can provide a survival benefit comparable to that of newer systemic therapies. Accordingly, TACE remains a valuable option in this era of new systemic therapies.

The dysregulation of kinases has emerged as a major class of targets for anticancer drug discovery given its node roles in the etiology of tumorigenesis, progression, invasion, and metastasis of malignancies, which is validated by the FDA approval of 28 small molecule kinase inhibitor (SMKI) drugs for cancer treatment at the end of 2015. While the preclinical and clinical data of these drugs are widely presented, it is highly essential to give an updated review on the medical indications, design principles and binding modes of these anti-tumor SMKIs approved by the FDA to offer insights for the future development of SMKIs with specific efficacy and safety.

Lenvatinib mesylate (LEN) is an oral tyrosine kinase inhibitor used to treat various cancers, including hepatocellular carcinoma (HCC). HCC treatment with LEN is associated with a very high incidence of adverse events. This study was aimed at investigating the incidence of LEN-induced palmar-planter erythrodysesthesia syndrome (PPES) and its relationship with patient demographics by analyzing clinical laboratory data of LEN-treated patients with HCC.

This was a single-centre, retrospective study of patients with HCC who received LEN between April 19, 2018, and September 30, 2020. The observation period was from 1 week before the start of LEN administration to 1 month after the end of administration.

Overall, 75 patients with HCC were enrolled. LEN-induced PPES was found in 48.0% (36/75 patients). In these patients, alkaline phosphatase (ALP), γ-Glutamyl transpeptidase (γ-GTP) and monocytes (MONO) were significantly high (ALP: p = 1.32 × 10-3, γ-GTP: p = 4.25 × 10-3 and MONO: p = 0.013). The cut off values of ALP, γ-GTP and MONO for LEN-induced PPES were estimated at 573 U/L, 89 U/L, and 310 counts/μL, respectively. In the multivariate analysis, γ-GTP and MONO were independent risk factors for LEN-induced PPES.

High γ-GTP and high MONO were risk factors for LEN-induced PPES.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related mortality worldwide. The emergence of combination therapy, atezolizumab (anti-PDL1, immune checkpoint inhibitor) and bevacizumab (anti-VEGF) has revolutionised the management of HCC. Despite this breakthrough, the best overall response rate with first-line systemic therapy is only about 30%, owing to intra-tumoural heterogeneity, complex tumour microenvironment and the lack of predictive biomarkers. Many groups have attempted to classify HCC based on the immune microenvironment and have consistently observed better outcomes in immunologically "hot" HCC. We summarised possible mechanisms of tumour immune evasion based on the latest literature and the rationale for combination/sequential therapy to improve treatment response. Lastly, we proposed future strategies and therapies to overcome HCC immune evasion to further improve treatment outcomes of HCC.

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the first for primary liver tumors. In recent years greater therapeutic advancement was represented by employment of tyrosine kinase inhibitors (TKIs) either in monotherapy or in combination with immune checkpoint inhibitors (ICIs).

Major attention was given to target therapies in the last couple of years, especially in those currently under phase II trials. Priority was given either to combinations of novel ICI and TKIs or those targeting alternative mutations of major carcinogenic pathways.

As TKIs are playing a more crucial role in HCC therapeutic strategies, it is fundamental to further expand molecular testing and monitoring of acquired resistances. Despite the recent advancement in both laboratory and clinical studies, further research is necessary to face the discrepancy in clinical practice.
