Liver cancer, more specifically hepatocellular carcinoma (HCC), is a global health issue and one of the dominant causes of cancer death around the world. In the past few decades, remarkable advances have been achieved in the systemic therapy of HCC. Immune checkpoint inhibitors (ICIs) have become a therapy mainstay for advanced HCC and have shown promise in the neoadjuvant therapy before resection. Despite these significant advancements, the compositions and functions of the immune system occur various alterations with age, called "immunosenescence", which may affect the antitumor effects and safety of ICIs, thus raising concerns that immunosenescence may impair elderly patients' response to ICIs. Therefore, it is important to learn more about the immunosenescence characteristics of elderly patients. However, the real-world elderly HCC patients may be not accurately represented by the elderly patients included in the clinical trials, affecting the generalizability of the efficacy and safety profiles from the clinical trials to the real-world elderly patients. This review summarizes the characteristics of immunosenescence and its influence on HCC progression and immunotherapy efficacy as well as provides the latest progress in ICIs available for HCC and discusses their treatment efficacy and safety on elderly patients. In the future, more studies are needed to clarify the mechanisms of immunosenescence in HCC, and to find sensitive screening tools or biomarkers to identify the patients who may benefit from ICIs.

The efficacy and safety of pembrolizumab in treating advanced hepatocellular carcinoma (HCC) are inconsistent across studies. This study sheds light on the efficacy and safety of pembrolizumab in advanced HCC patients.

Several databases were comprehensively searched up to January 13, 2025, to identify studies assessing pembrolizumab for advanced HCC. Outcome indicators included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), rash, adverse events (AEs), and severe adverse events (SAEs). Pooled effects were estimated through hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs). R 4.4.1. was employed for statistical analyses.

Twenty-two studies involving 2964 patients were encompassed. Meta-analysis indicated that pembrolizumab demonstrated an ORR of 28% in single-arm analyses. Pembrolizumab significantly improved ORR in comparison to placebo (OR = 2.57, 95% CI: 1.32-5.03) but showed no significant advantage over nivolumab. Pembrolizumab markedly enhanced PFS (HR = 0.76, 95% CI: 0.69-0.85) and OS (HR = 0.78, 95% CI: 0.70-0.88) compared to placebo, but no significant differences were observed when compared to nivolumab. Pembrolizumab significantly raised the risk of rash in comparison to placebo (OR = 2.27, 95% CI: 1.55-3.31) but showed no significant difference versus nivolumab. The pembrolizumab group showed a higher incidence of AEs (OR = 1.94, 95% CI: 1.42-2.64) and SAEs (OR = 2.10, 95% CI: 1.04-4.25) than the placebo group, with no significant difference between pembrolizumab and nivolumab.

This study proves that pembrolizumab may have promising therapeutic effects in patients with advanced HCC, although no clear advantage over nivolumab was observed. The occurrence of AEs warrants attention in clinical practice.

Hepatocellular carcinoma (HCC) is the sixth most common malignancy and the third leading cause of cancer-related death worldwide. Contemporary advances in systemic and locoregional therapies have led to changes in peer-reviewed guidelines regarding systemic therapy as well as the possibility of downstaging disease that may enable some patients with advanced disease to ultimately undergo partial hepatectomy or transplantation with curative intent. This review focuses on all modalities of therapy for HCC, guided by modern-day practice-changing randomized data where available. The surgical management of HCC, including resection and transplantation, both of which have evolving criteria for what is considered biologically resectable and transplantable, as well as locoregional therapy (i.e., therapeutic embolization, ablation, radiation, and hepatic arterial infusion), are discussed. Historical and modern-day practice-changing trials evaluating immunotherapy with targeted therapies for advanced disease, as well as adjuvant systemic therapy, are also summarized. In addition, this article examines the critical dimension of toxicities and patient-oriented considerations to ensure a comprehensive and balanced discourse on treatment implications.

Hepatocellular carcinoma (HCC) remains one of the major threats to human health worldwide. The emergence of systemic therapeutic options has greatly improved the prognosis of patients with HCC, particularly those with advanced stages of the disease. In this review, we discussed the pathogenesis of HCC, genetic alterations associated with the development of HCC, and alterations in the tumor immune microenvironment. Then, important indicators and emerging technologies related to the diagnosis of HCC are summarized. Also, we reviewed the major advances in treatments for HCC, offering insights into future prospects for next-generation managements.

Hepatocellular carcinoma (HCC) is a primary liver cancer characterized by poor immune cell infiltration and a strongly immunosuppressive microenvironment. Traditional treatments have often yielded unsatisfactory outcomes due to the insidious onset of the disease. Encouragingly, the introduction of immune checkpoint inhibitors (ICIs) has significantly transformed the approach to HCC treatment. Moreover, combining ICIs with other therapies or novel materials is considered the most promising opportunity in HCC, with some of these combinations already being evaluated in large-scale clinical trials. Unfortunately, most clinical trials fail to meet their endpoints, and the few successful ones also face challenges. This indicates that the potential of ICIs in HCC treatment remains underutilized, prompting a reevaluation of this promising therapy. Therefore, this article provides a review of the role of immune checkpoints in cancer treatment, the research progress of ICIs and their combination application in the treatment of HCC, aiming to open up avenues for the development of safer and more efficient immune checkpoint-related strategies for HCC treatment.

Overall survival (OS) is recommended as a gold standard endpoint but has some limitations. We aimed to finding more effective surrogate endpoints for advanced hepatocellular carcinoma (HCC) treated with immune checkpoint inhibitors (ICIs).

Three online databases were searched for randomized control trials (RCTs) on HCC, published between January 2015 and July 2023, that evaluated ICIs and reported progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and OS. The correlation between the potential surrogate endpoints and OS was evaluated at the trial, arm, and patient levels. The prediction models were validated in single-arm or non-RCTs. Individual data were collected from a real-world (RW) cohort with advanced HCC underwent ICI monotherapy at three tertiary medical centers in China.

Ten RCTs (6023 participants) with 11 comparisons were included. PFS had a moderately significant association with OS (R2 = 0.50, p = 0.014). ORR, DCR, and OS showed weak correlations. On limiting the analysis to ICI monotherapy studies, the correlations of OS with PFS became stronger (R2 = 0.85, p = 0.02). The RW cohort also verified that PFS was closely related to OS when patient received with ICI monotherapy.

PFS are recommended as surrogate markers in patients with advanced HCC treated with ICI monotherapy.

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Multiple treatment modalities are available for the management of HCC, depending on its stage as determined by the Barcelona Clinic Liver Cancer staging system. Because liver transplantation (LT) theoretically removes the cancer and replaces the organ at risk for future malignancy, LT is often considered the most definitive and one of the most efficacious treatment options for HCC. Nevertheless, the success and efficacy of liver transplantation depend on various tumor characteristics. As a result, multiple criteria have been developed to assess the appropriateness of a case of HCC for LT, with the pioneering Milan Criteria established in 1996. Over the past 20 to 30 years, these criteria have been critically evaluated, expanded, and often liberalized to make LT for patients with HCC a more universally applicable option. Furthermore, the development of other treatment modalities has enabled downstaging and bridging strategies for HCC prior to LT. In this narrative and comprehensive review, we provided an update on recent trends in the epidemiology of HCC, selection criteria for LT, implementation of LT across different regions, treatment modalities available as bridges, downstaging strategies, alternatives to LT, and, finally, post-LT surveillance.

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death and the sixth most prevalent cancer worldwide. However, most patients with HCC are at an advanced stage at the time of clinical diagnosis, making surgery impossible. In the past, targeted therapeutic drugs such as sorafenib and lenvatinib were the main treatments. With recent breakthroughs in medicine, immunotherapy, particularly immune checkpoint inhibitors (ICIs), has garnered interest and has been extensively studied for clinical treatment. In addition to single-agent therapies, combination regimens involving ICIs have also been developed. Despite this progress, not all patients with HCC benefit from immunotherapy. Therefore, to improve the treatment response rates, it is crucial to identify patients with HCC who are suitable for immunotherapy. The exploration and validation of markers to predict the outcomes of immunotherapeutic treatments in patients with HCC are of clinical importance. In this article, we provide a comprehensive review of research progress in immunotherapy, particularly ICIs and combination therapies, for HCC. Furthermore, we summarize the clinical indicators and tumor markers discovered in recent years to forecast immunotherapy outcomes in patients with HCC. We also outline predictive markers for the occurrence of immune-related adverse events in patients with HCC receiving immunotherapy and discuss future research directions in the immunotherapeutic treatment landscape.

Background: Hepatocellular carcinoma (HCC) is a prevalent and highly lethal form of liver cancer, with limited effective treatment options, particularly in the advanced stages. Immunotherapy using PD-1 inhibitors has emerged as a promising treatment modality, yet a substantial proportion of patients exhibit resistance or fail to respond to such therapies. This study aimed to elucidate the role of G0/G1 Switch 2 (G0S2) in regulating PD-L1 expression in monocytes within the HCC tumor microenvironment and to investigate its impact on the efficacy of PD-1 inhibitors. Methods: Gene expression data among HCC patients treated with PD-1 inhibitors were obtained from the HCC single-cell sequencing database; immunohistochemistry was performed to detect G0S2 expression in liver cancer tissues and adjacent non-tumorous tissues of HCC patients; flow cytometry was utilized to analyze the expression of G0S2, PD-L1, CD206, and CD14 in PBMCs from HCC patients; and CD8+T cell proliferation and IFN-γ secretion were used to evaluate the impact of G0S2 knockdown. Results: Utilizing single-cell sequencing data from HCC patients, we identified that G0S2 expression was significantly elevated in the non-responders (NR) compared to responders (R) to PD-1 inhibitor therapy. The immunohistochemical analysis confirmed higher levels of G0S2 in HCC tumor tissues and adjacent non-tumorous tissues, while the flow cytometry revealed the increased expression of G0S2, PD-L1, and CD206 in peripheral blood mononuclear cells (PBMCs) from NR patients compared to R patients and healthy controls. The functional experiments involving the knockdown of G0S2 in the THP-1 monocyte cell line resulted in a significant reduction in PD-L1 expression and a concomitant increase in CD8+T cell proliferation and IFN-γ production. Conclusions: These findings indicate that G0S2 facilitates the upregulation of PD-L1 in monocytes, thereby suppressing T cell activity and contributing to resistance against PD-1 inhibitors in HCC. The high expression of G0S2 in peripheral blood monocytes offers a non-invasive and easily detectable biomarker for predicting the efficacy of PD-1 inhibitor therapy. Consequently, targeting G0S2 may enhance the responsiveness to immunotherapy in HCC patients, providing a new avenue for optimizing treatment strategies and improving patient outcomes.

Hepatocellular carcinoma (HCC) remains one of the most prevalent and lethal forms of liver cancer, contributing significantly to global cancer-related mortality. Conventional treatments, including surgical resection, liver transplantation, and systemic therapies such as multikinase inhibitors and immune checkpoint inhibitors, often face limitations such as systemic toxicity and drug resistance, emphasizing the urgent need for more effective therapeutic strategies. In this study, we developed a galactose-functionalized dendrimer (Gal24) conjugated with a natural flavonoid, silibinin, (Gal24-Sil), for HCC therapy. In our previous study, we developed a Gal24 dendrimer to target hepatocytes in vivo. Here, we further demonstrated that the conjugation of silibinin to Gal24 dendrimer platform significantly enhanced its solubility and efficacy. In vitro studies demonstrated that Gal24-Sil conjugates significantly improved the anticancer efficacy of silibinin in HepG2 and Hep3B liver cancer cells. The conjugate induced an inflammatory response and reactive oxygen species (ROS) generation, triggering cellular apoptosis and necrosis. Furthermore, Gal24-Sil effectively reduced cell proliferation by promoting mitochondrial membrane potential (MMP) depolarization and inducing DNA damage. Our findings demonstrate the potential of Gal24-Sil as a promising nanoplatform for HCC therapy, offering enhanced therapeutic efficacy over free Silibinin. This study highlights the broader applicability of the Gal24 dendrimer platform for addressing various liver diseases.

Locoregional therapies play a fundamental role in the treatment of patients with early and intermediate and locally advanced hepatocellular carcinomas. With encouraging recent advances in immunotherapy-based systemic therapies, locoregional therapies are being both promoted and challenged by new systemic therapy options. Combined locoregional and systemic therapies might enhance treatment outcomes compared with either option alone. This Series paper summarises the existing data on locoregional and systemic therapies for hepatocellular carcinoma, and discusses evidence from studies investigating their combination with a focus on their synergistic efficacy and safety.

Over the past years, there has been a remarkable advance in the systemic treatment options for advanced HCC. The overall survival has gradually increased over time, with larger benefits for patients with sensitive tumors and preserved liver function, the latter being an essential condition for the delivery of sequential lines of treatment and optimization of clinical outcomes. With the approval of new first-line agents and the introduction of immune checkpoint inhibitor-based therapies, the treatment landscape of advanced HCC is becoming wider than ever. Atezolizumab plus bevacizumab and, more recently, durvalumab plus tremelimumab have entered the clinical practice and are the current standard of care for treatment-naïve patients, surpassing sorafenib and lenvatinib monopoly. As no head-to-head comparisons are available among all the first-line treatment options, the recommendation for the most appropriate choice and sequence is patient-driven and integrates efficacy data with clinical comorbidities, background liver disease, and the safety profile of available drugs. In addition, predictive biomarkers for successful patients' stratification are yet to be available and constitute the focus of ongoing research. The treatment algorithm is likely to become even more complex since systemic therapeutic approaches are now being translated into earlier stages of the disease, with an impact on the evolution of the sequential treatment of patients with HCC.

Hepatocellular carcinoma (HCC) is one of the common malignant cancers worldwide. Although immunotherapy has improved the treatment outcome in HCC, a significant percentage of patients with advanced HCC still cannot benefit from immunotherapy. Therefore, developing new targets or combination therapeutic strategies to improve the efficacy of immunotherapy is urgently needed. A deeper understanding of the mechanisms underlying immune regulation may help in this regard. The tumor microenvironment (TME) consists of a diverse set of components modulating the efficacy of immunotherapy. Cancer-associated fibroblasts (CAFs) are critical components of the TME and can regulate both tumor and immune cells through secreted cytokines and exosomes that impact various signaling pathways in target cells. CAF-derived cytokines can also participate in extracellular matrix (ECM) remodeling, thereby impacting cancer progression and tumor responsiveness to immunotherapy among other effects. A thorough understanding of the phenotypic and functional profile dynamism of CAFs may lead the way for new treatment strategies and/or better treatment outcomes in HCC patients. In this review, we outline the biomarkers and functional heterogeneity of CAFs in HCC and elaborate on molecular mechanisms of CAFs, including anti-programmed cell death protein 1 (PD-1)/PD-ligand 1 (PD-L1) immunotherapy. We also examine current clinical implications of CAFs-related targets as potential therapeutic candidates in HCC.

Overwhelming evidence suggests that the gut microbiota modulates tumor response to immune checkpoint inhibitors (ICIs). The probiotic Bacteroides fragilis (BF839) was extensively used in China to improve gut microbiota dysbiosis-related symptoms. We hypothesized that probiotic BF839 could enhance tumor sensitivity to ICIs.

In the preclinical studies, mice received BF839 orally, PD-1 intraperitoneal injection, or a combination therapy of the two agents. The antitumor effect of BF839 was investigated by assessing the tumor growth and tumor immune microenvironment. Mice fecal samples were collected for 16S rRNA sequencing. Fresh tumor samples were collected for 16S RNA sequencing. The data of 29 patients with advanced solid tumor who received BF839 adjuvant therapy were retrospectively evaluated. The primary endpoint was overall survival (OS).

Among patients with advanced solid tumors undergoing ICIs and chemotherapy, patients in BF839 long-term adjuvant treatment group had longer OS (p = 0.0101) than the BF839 short-term adjuvant treatment group. In the preclinical studies, we found that monotherapy with BF839 or anti-PD-1 antibody significantly inhibit tumor growth. Interestingly, BF839 worked synergistically with anti-PD-1 antibody and induced tumor regression, mediated by increased CD8+T cell infiltration. Mechanistically, BF839 induced tumor suppression was regulated by the cGAS-STING pathway. 16S rRNA sequencing results of mice fecal samples showed that BF839 treatment increased gut microbiota diversity.

Overall, our data suggest that BF839 enhanced tumor sensitivity to ICIs through cGAS-STING signaling. In the future, the application of probiotic BF839 to regulate gut microbiota may be a new strategy to enhance the efficacy of ICIs.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, with chronic infections by hepatotropic viruses such as hepatitis B virus (HBV), and hepatitis C virus (HCV), being major risk factors. Chronic infections with these viruses are the leading cause of HCC worldwide, with HBV alone responsible for over 50% of cases. Despite advances in direct-acting antivirals (DAAs) for HCV and nucleos(t)ide analogues (NAs) for HBV, challenges remain in HCC prevention, early detection, and treatment. Recent research highlights the role of viral-induced metabolic alterations, such as the Warburg effect, mitochondrial dysfunction, and lipid dysregulation, in promoting HCC. Moreover, immune checkpoint inhibitors have emerged as effective treatments for advanced HCC, though responses vary between HBV- and HCV-related cancers. Additionally, novel therapeutic approaches and metabolic-targeted therapies offer promising avenues for virus-associated HCC treatment. Advancements in liquid biopsy biomarkers and artificial intelligence-driven diagnostics are improving HCC surveillance and risk stratification, potentially enabling earlier interventions. While HBV vaccination has significantly reduced HCC incidence, disparities in global vaccination coverage persist. Furthermore, antiviral therapies combined with structured surveillance programs have proven effective in reducing HCC incidence and mortality. This review highlights the complex connection between viral, genetic, and environmental factors in HCC development and underscores the importance of integrated prevention strategies to reduce its burden globally.

Lenvatinib (LEN) is the recommended first-line therapy for unresectable hepatocellular carcinoma (uHCC), but resistance frequently develops, and limited data exist on second-line treatments. This study evaluated the efficacy and safety with a focus on the sorafenib (SOR) or regorafenib (REG)- based monotherapy or combination therapy in patients with uHCC after failure of first-line LEN.

Patients with first-line LEN failure between May 2018 and December 2023 were retrospectively collected. Based on second-line regimens, 70 patients were divided into two groups: the TKI group (n = 21) and the TKI-ICI group (n = 49). Overall survival (OS) and progression-free survival (PFS) were analyzed by Kaplan-Meier methods, and multivariate analysis was performed to identify prognostic factors.

In the TKI-ICI group, median PFS was 5.27 months and median OS was 12.53 months. In the TKI group, median PFS was 3.10 months and median OS was 7.50 months. The objective response rate (ORR) was 19.1% in the TKI group and 16.3% in the TKI-ICI group. The disease control rate (DCR) was 85.7% in the TKI-ICI group and 61.9% in the TKI group. In the TKI-ICI cohort, multivariable Cox analysis revealed the high albumin to neutrophil ratio index (ANRI) was an independent predictor for PFS, while alpha-fetoprotein > 400 ng/mL was the independent predictor for OS. Safety profiles in both cohorts showed manageable toxicity, with no treatment-related deaths.

The combination of TKI and ICI presents a promising second-line treatment option after LEN failure, regardless of the specific second-line TKI used.

Circulating tumor cells (CTCs) are precursors of cancer metastasis. However, how CTCs evade immunosurveillance during hematogenous dissemination remains unclear.

We identified CTC-platelet adhesions by single-cell RNA sequencing and multiplex immunofluorescence of blood samples from multiple cancer types. Clinically, CTC-platelet aggregates were associated with significantly shorter progression-free survival and overall survival in patients with HCC. In vitro, ex vivo, and in vivo assays demonstrated direct platelet adhesions gifted cancer cells with an evasive ability from NK cell killing by upregulating inhibitory checkpoint CD155 (PVR cell adhesion molecule), therefore facilitating distant metastasis. Mechanistically, CD155 was transcriptionally regulated by the FAK/JNK/c-Jun cascade in a platelet contact-dependent manner. Further competition assays and cytotoxicity experiments revealed that CD155 on CTCs inhibited NK-cell cytotoxicity only by engaging with immune receptor TIGIT, but not CD96 and DNAM1, another 2 receptors for CD155. Interrupting the CD155-TIGIT interactions with a TIGIT antibody restored NK-cell immunosurveillance on CTCs and markedly attenuated tumor metastasis.

Our results demonstrated CTC evasion from NK-cell-mediated innate immunosurveillance mainly through immune checkpoint CD155-TIGIT, potentially offering an immunotherapeutic strategy for eradicating CTCs.

Portal and hepatic vein tumor thrombosis is associated with inferior outcomes in patients with hepatocellular carcinoma (HCC), and systemic treatment alone is often insufficient. This phase II trial evaluated the efficacy and safety of combining sorafenib with radiotherapy in advanced HCC with thrombosis.

Registered at ClinicalTrials.gov (NCT03535259), this phase II single-arm prospective trial targeted patients with HCC with portal or hepatic vein tumor thrombosis, liver minus gross tumor volume >700 ml, and Eastern Cooperative Oncology Group Performance Status scores of 0 or 1. Participants underwent 40-66 Gy radiotherapy for the hepatic primary tumor and vein tumor thrombosis, with concurrent oral sorafenib (400 mg twice daily) until disease progression or unacceptable adverse events. The primary endpoint was median overall survival (mOS) and the secondary endpoints included overall response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and Modified Response Evaluation Criteria in Solid Tumors (mRECIST), median progression-free survival (mPFS), time to tumor progression (TTP), tumor thrombosis control, and grade ≥3 adverse events.

Between May 2018 and January 2020, 86 patients were enrolled with a median radiotherapy dose of 54 Gy (40-65 Gy). At a median follow-up of 17.2 months, mOS, mPFS, and TTP stood at 16.5, 6.1, and 6.8 months, respectively. ORR reached 47.7% and 52.3% per RECIST and mRECIST, respectively. For the tumor thrombosis, 2-year control rates per mRECIST were 93.1%. No grade 5 adverse events were noted, whereas thrombocytopenia (22.1%) and leukopenia (14.0%) were the main grade 3 adverse events.

Concurrent sorafenib and radiotherapy is an effective and well-tolerated treatment for patients with HCC with portal or hepatic vein tumor thrombosis.

Treatment options for patients with hepatocellular carcinoma (HCC) and vascular tumor thrombus are limited. The efficacy and safety of concurrent sorafenib and radiation for HCC with portal or hepatic vein tumor thrombosis has not been elucidated. This phase II trial shows that concurrent sorafenib and radiotherapy is effective and well-tolerated in the treatment of advanced HCC with portal vein or hepatic vein tumor thrombosis.

This study is registered at ClinicalTrials.gov (NCT03535259).

Over the past several years, the therapeutic landscape for patients with advanced, unresectable, or metastatic hepatocellular carcinoma has been transformed by the incorporation of checkpoint inhibitor immunotherapy into the treatment paradigm. Frontline systemic treatment options have expanded beyond anti-angiogenic tyrosine kinase inhibitors, such as sorafenib, to a combination of immunotherapy approaches, including atezolizumab plus bevacizumab and durvalumab plus tremelimumab, both of which have demonstrated superior response and survival to sorafenib. Additionally, combination treatments with checkpoint inhibitors and tyrosine kinase inhibitors have been investigated with variable success. In this review, we discuss these advances in systemic treatment with immunotherapy, with a focus on understanding both the underlying biology and mechanism of these strategies and their efficacy outcomes in clinical trials. We also review challenges in identifying predictive biomarkers of treatments and discuss future directions with novel immunotherapy targets.

The use of targeted drugs and immunotherapy has significantly impacted the treatment of Colorectal Cancer. However, horizontal comparison among various regimens is extremely rare. Therefore, we evaluated the survival efficacy of multiple treatment regimens of targeted therapy and/or immunotherapy with or without chemotherapy in patients with Colorectal Cancer.

A systematic search was conducted in PubMed, EMBASE, and Cochrane databases, covering the period from the establishment of the databases to October 29, 2024. To obtain articles that met the inclusion and exclusion criteria and contained the required data for conducting a network meta-analysis (NMA). The NMA evaluated overall survival (OS) and progression-free survival (PFS).

A total of 90 studies were identified, comprising a sample size of 33,167 subjects. In terms of PFS, compared with simple chemotherapy strategies, most of the other single or combined strategies are significantly effective, among which targeted therapy strategies have more advantages. Encorafenib + Binimetinib + Cetuximab (ENC-BIN-CET) shows significant benefits in all comparisons except when compared with Chemotherapy + Cetuximab + Dalotuzumab (Chemo-CET-DAL), Encorafenib + Cetuximab (ENC-CET), and Panitumumab + Sotorasib (PAN-SOT). The ENC-CET and PAN-SOT targeted strategies also show significant benefits. Pembrolizumab (PEM) monotherapy has advantages over all others except when it is not superior to some targeted strategies. Chemotherapy + Bevacizumab + Atezolizumab is only inferior to some strategies. In terms of OS, the combinations of Chemotherapy + Bevacizumab, ENC-CET, Chemotherapy + Panitumumab, and ENC-BIN-CET are superior to simple chemotherapy regimens. ENC-BIN-CET shows OS benefits in all comparisons except some. ENC-CET significantly improves OS in most cases, and PEM also significantly improves OS in some regimens. In the probability ranking of OS and PFS, ENC-BIN-CET has the best effect, followed by ENC-CET.

In conclusion, pembrolizumab is still effective in prolonging survival. Dual- and triple-drug targeted strategies are the best in terms of OS and PFS, and the combination of targeted immunotherapy and chemotherapy also works. However, not all combinations are beneficial. As targeted drugs play an active role, specific drugs for colorectal cancer regimens should be carefully selected.

Understanding the relationship between the Objective Response Rate (ORR) and survival outcomes, notably Progression-Free Survival (PFS) and Overall Survival (OS), is relevant for assessing the efficacy of regimens in oncology. We evaluate the relationship between ORR, PFS and OS in immuno-oncology (IO) trials. Data from 68 clinical trials submitted to the FDA were evaluated, examining immunotherapy regimens, notably immune checkpoint inhibitors such as anti-programmed death (ligand)-1 [anti-PD-(L)1], cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) inhibitors and combination therapies [e.g., IO + IO, anti-PD-L1 + chemotherapy, anti-PD-L1 + CTLA-4, anti-PD-L1 + TKI (tyrosine kinase inhibitors)]. Studies were included based on their reporting of ORR, PFS, and OS. Of the 68 clinical trials reviewed, 55 were included in the analysis. The correlation between ORR and PFS was moderate across most immunotherapy regimens, indicating that ORR can serve as a useful predictor of short-term disease control. However, the correlation between ORR and OS was weaker, especially in trials including combination therapies, indicating that ORR alone may not reliably predict long-term survival outcomes. ORR predicts PFS better in first-line treatment but declines in later lines and remains a weak OS predictor overall. Differing degrees of correlation between ORR and survival metrics, particularly across treatment lines and combinations, are observed. While ORR can serve as a surrogate marker for PFS in IO trials, its utility in predicting OS is restricted and the interpretation of the relationship between ORR and PFS or OS is a key limitation. Rather, a decline in PFS with increasing ORR may reflect trial differences rather than a direct relationship. Future analyses should adopt better methodologies to capture these dynamics and focus on improving surrogate endpoints for immunotherapy to improve clinical trial design and patient outcomes.

Viral infections contribute to a higher incidence of cancer than any other individual risk factor. This study aimed to compare the clinical and molecular features of four viral-associated cancers: stomach adenocarcinoma (STAD), head and neck squamous cell carcinoma (HNSC), liver hepatocellular carcinoma (LIHC), and cervical squamous cell carcinoma (CESC). Patients were categorized based on viral infection status, as provided in the clinical data, into virus-associated and non-virus-associated groups, followed by a comprehensive comparison of clinical and molecular features. Our analysis disclosed that viral infections confer unique clinical and molecular signatures to their associated tumors. Specifically, human papillomavirus-associated (HPV+) HNSC and hepatitis B virus-associated (HBV+) LIHC patients were predominantly male, younger, and exhibited better clinical prognoses. Virus-associated tumors displayed enhanced immune microenvironments and high DNA damage response scores, while non-virus-associated tumors were enriched in stromal signatures. HPV+ HNSC and Epstein-Barr virus-associated (EBV+) STAD showed similarities across multi-omics features, including better responses to immunotherapy, lower TP53 mutation rates, tumor mutation burden (TMB), and copy number alteration (CNA). Conversely, HBV+, Hepatitis C virus-associated (HCV+) LIHCs and HPV+ CESC were more genomically unstable due to high TP53 mutation rates, TMB, and CNA. At the protein level, Caspase-7 and Syk were upregulated in HPV+ HNSC and EBV+ STAD, and positively correlated with the enrichment levels of CD8 + T cell, PD-L1, and cytolytic activity. Patient stratification based on infection status has significant clinical implications, particularly for patient prognosis and drug response.

Background/Objectives: Pembrolizumab, an immune checkpoint inhibitor targeting programmed death 1 (PD-1), is a widely employed therapy for various gastrointestinal (GI) cancers. We conducted a systematic review of clinical trials investigating pembrolizumab monotherapy in GI cancer patients to assess the spectrum and incidence of immune-related adverse events (irAEs) associated with pembrolizumab. Methods: A comprehensive search of PubMed/MEDLINE was performed to identify clinical trials investigating pembrolizumab monotherapy in GI cancer patients. Primary endpoints included the incidence of grade 3 or higher irAEs and the rate of treatment discontinuation due to irAEs. Secondary endpoints encompassed the incidence of any-grade irAEs, as well as specific irAEs. Results: Data extraction and analysis were performed on 25 articles. The analysis included 3101 patients with a median age of 62 years (range 53-68), with 30.2% being female. Tumor types encompassed were colorectal (12%), esophagogastric (46%), hepatocellular carcinoma (24%), and other GI tumor types (18%). The rate of treatment discontinuation due to irAEs was 6.8%. The most prevalent grade 3 or higher irAEs were hepatitis (3.6%), pneumonitis (0.8%), and colitis (0.7%). Death attributed to irAEs was infrequent (0.9%). Conclusions: In patients with GI cancers treated with pembrolizumab monotherapy, severe toxicities are infrequent, and irAEs leading to treatment discontinuation or death are uncommon.

Transarterial chemoembolisation (TACE) is standard care for unresectable, non-metastatic hepatocellular carcinoma. We aimed to evaluate the addition of lenvatinib and pembrolizumab to TACE versus dual placebo plus TACE in patients with unresectable, non-metastatic hepatocellular carcinoma.

In this multicentre, randomised, double-blind, phase 3 study (LEAP-012), patients were recruited from 137 global sites in 33 countries or regions. Eligible patients were age 18 years or older with unresectable, non-metastatic hepatocellular carcinoma not amenable to curative treatment, but with tumours amenable to TACE, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and Child-Pugh class A disease. Eligible participants were randomly assigned (1:1), stratified by study site, α-fetoprotein level, ECOG performance status, albumin-bilirubin grade, and tumour burden, by a central interactive response system, to receive TACE and either oral lenvatinib (bodyweight ≥60 kg: 12 mg; bodyweight <60 kg: 8 mg; once daily) plus intravenous pembrolizumab (400 mg once every 6 weeks for up to 2 years) or matched dual placebo (oral and intravenous). Primary endpoints were progression-free survival (threshold one-sided p=0·025), per Response Evaluation Criteria in Solid Tumours version 1.1 (modified for the current study to allow for up to five target tumours in the liver and requiring new intrahepatic tumours to meet LI-RADS 5 criteria to be considered progressive disease) by blinded independent central review, and overall survival (threshold one-sided p=0·0012) in the intention-to-treat (ITT) population (ie, all participants randomly assigned to treatment). Safety was assessed in the as-treated population (ie, all participants who were randomly assigned and received at least one dose of any study treatment). Here, we report results from the first interim analysis (final analysis for progression-free survival). This study is registered with ClinicalTrials.gov, NCT04246177, and is active but not recruiting.

Between May 22, 2020, and Jan 11, 2023, 847 patients were screened, of whom 480 (57%) were enrolled and randomly assigned to receive TACE plus lenvatinib plus pembrolizumab (n=237) or TACE plus dual placebo (n=243; ITT population). Median age was 66 years (IQR 58-73), 82 (17%) of 480 participants were female, 398 (83%) were male, 98 (20%) were White, 347 (72%) were Asian, four (1%) were Black or African American, and five (1%) were American Indian or Alaska Native. Median follow-up as of data cutoff (Jan 30, 2024) was 25·6 months (IQR 19·5-32·4). Median progression-free survival was 14·6 months (95% CI 12·6-16·7; 132 events [20 deaths and 112 progressions]) with lenvatinib plus pembrolizumab and 10·0 months (8·1-12·2; 154 events [eight deaths and 146 progressions]) with placebo (hazard ratio [HR] 0·66 [95% CI 0·51-0·84]; one-sided p=0·0002). 69 (29%) of 237 in the lenvatinib plus pembrolizumab group and 82 (34%) of 243 from the placebo group died, with a 24-month overall survival rate of 75% (95% CI 68-80) in the lenvatinib plus pembrolizumab group and 69% (62-74) in the placebo group (HR 0·80 [95% CI 0·57-1·11]; one-sided p=0·087). Grade 3 or worse treatment-related adverse events occurred in 169 (71%) of 237 participants in the lenvatinib plus pembrolizumab group and in 76 (32%) of 241 in the placebo group, the most common of which were hypertension (57 [24%] vs 18 [7%]) and platelet count decreased (27 [11%] vs 15 [6%]). Deaths due to treatment-related adverse events occurred in four (2%) participants in the lenvatinib plus pembrolizumab group (n=1 each due to hepatic failure, gastrointestinal haemorrhage, myositis, and immune-mediated hepatitis) and one (<1%) in the placebo group (due to brain stem haemorrhage).

TACE plus lenvatinib plus pembrolizumab showed significant, clinically meaningful improvement in progression-free survival in patients with unresectable, non-metastatic hepatocellular carcinoma compared with TACE plus placebo. The numerical improvement in overall survival is encouraging, but longer follow-up is necessary.

Pembrolizumab plus Lenvatinib is regarded as a significant treatment option for advanced unresectable hepatocellular carcinoma (HCC). This study aims to meticulously monitor and identify adverse events (AEs) related to this combined therapy, enhance patient safety, and offer evidence-based recommendations for the appropriate use of these drugs. We gathered adverse drug reactions (ADRs)-related data from the FAERS database for HCC patients who received Pembrolizumab, both alone and in combination with Lenvatinib from the first quarter of 2014 to the fourth quarter of 2023. ADRs signal detection was performed using the ROR, PRR, BCPNN, MHRA, and MGPS methods. We gathered data on 459 and 358 AEs from patients with HCC treated with pembrolizumab alone and in combination with lenvatinib, respectively. Using four signal quantification techniques, we identified 50 and 38 distinct AEs, which were classified into 15 different System organ class (SOC) categories. Notably, the most common AEs associated with pembrolizumab were gastrointestinal disorders and hepatobiliary disorders. In both patient groups, the most frequently reported AEs were hepatic encephalopathy, blood bilirubin increased and diarrhea. We also observed some unexpected significant AEs, such as dehydration, skin ulcers, and intestinal perforation. The countries reporting the highest number of AEs were the United States, followed by China, France, and Japan. The median onset time for AEs related to pembrolizumab alone and its combination with lenvatinib was 80.5 days (interquartile range 20.0-217.3 days) and 77.5 days (interquartile range 19.7-212.3 days), respectively. This study offers new insights into the monitoring and management of ADRs in HCC patients receiving pembrolizumab alone or in combination with lenvatinib. It is crucial to closely monitor the safety of this treatment regimen in HCC patients to avoid serious AEs.

Infiltrative hepatocellular carcinoma (HCC) is often associated with an unfavorable prognosis, posing a challenge in determining the optimal therapeutic approach. Immunotherapy, employing immune checkpoint inhibitors (ICIs), has become a preferred first-line treatment for advanced HCC. However, the overall effectiveness of ICIs in patients with infiltrative HCC remains unclear. This study aims to compare the effect of ICI treatment on clinical outcomes between patients with infiltrative and non-infiltrative HCC.

A retrospective cohort consisting of unresectable HCC patients who underwent immunotherapy with ICIs, categorized into infiltrative and non-infiltrative groups was studied. Primary outcomes comprised treatment response according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria, progression-free survival (PFS), and overall survival (OS).

Of 198 patients, 60 (30.3%) had infiltrative HCC, while 138 (69.7%) had non-infiltrative HCC. In the infiltrative group, the objective response rate (ORR) was 36.7% and the disease control rate (DCR) was 55.0%. For the non-infiltrative group, the ORR was 33.3% and the DCR was 56.5%, showing no significant difference between the two groups. However, patients in the infiltrative group had significantly shorter median of PFS and OS following immunotherapy, with a PFS of 4.1 months (95% CI: 2.5-6.7; p = 0.0409) and an OS of 10.4 months (95% CI: 6.7-14.4; p = 0.0268), compared with the non-infiltrative group, which had a PFS of 5.5 months (95% CI: 3.2-7.6) and an OS of 17.0 months (95% CI: 12.8-21.8).

For immunotherapy, infiltrative HCC exhibits treatment responses similar to non-infiltrative HCC. Nonetheless, infiltrative HCC is associated with shorter survival outcomes, compared with non-infiltrative type. Our findings emphasize the essential of considering type discrepancies when developing management strategies for immunotherapy.

Accumulating evidence suggests that microRNAs derived from macrophage exosomes can regulate the stemness and progression of cancer. However, the interaction mechanisms between HCC cells and tumor-associated macrophages remain unclear.

Exosomes were extracted from control or CD63 overexpression macrophages and co-cultured with HCC cells. The stemness, proliferation, epithelial-mesenchymal transition, and in vivo tumorigenicity of HCC cells were assessed to determine the role of CD63-high macrophage-derived exosomal miR-6876-5p in HCC. The binding relationship between miR-6876-5p and the PTEN/Akt axis was also investigated.

Elevated CD63 expression was associated with increased tumor-associated macrophage infiltration and poorer prognosis in HCC. CD63-high macrophage-derived exosomes enhanced HCC cell proliferation, stemness, and epithelial-mesenchymal transition. miR-6876-5p within these exosomes was identified as a key mediator, promoting HCC progression by targeting PTEN and activating the Akt signaling pathway. In vivo studies confirmed that CD63-high macrophage-derived exosomal miR-6876-5p accelerated tumor growth and enhanced stemness in HCC cells.

CD63-high macrophage-derived exosomes, particularly those enriched with miR-6876-5p, play a pivotal role in HCC progression by enhancing stemness and promoting epithelial-mesenchymal transition through the PTEN/Akt pathway. Targeting these exosomes and their microRNAs offers a promising therapeutic strategy forHCC.

Immunology-based therapies are emerging as an effective cancer treatment, using the body's immune system to target tumors. Immune checkpoints, which regulate immune responses to prevent tissue damage and autoimmunity, are often exploited by cancer cells to avoid destruction. The discovery of checkpoint proteins like PD-1/PD-L1 and CTLA-4 was pivotal in developing cancer immunotherapy. Immune checkpoint inhibitors (ICIs) have shown great success, with FDA-approved drugs like PD-1 inhibitors (Nivolumab, Pembrolizumab, Cemiplimab), PD-L1 inhibitors (Atezolizumab, Durvalumab, Avelumab), and CTLA-4 inhibitors (Ipilimumab, Tremelimumab), alongside LAG-3 inhibitor Relatlimab. Research continues on new checkpoints like TIM-3, VISTA, B7-H3, BTLA, and TIGIT. Biomarkers like PDL-1 expression, tumor mutation burden, interferon-γ presence, microbiome composition, and extracellular matrix characteristics play a crucial role in predicting responses to immunotherapy with checkpoint inhibitors. Despite their effectiveness, not all patients experience the same level of benefit, and organ-specific immune-related adverse events (irAEs) such as rash or itching, colitis, diarrhea, hyperthyroidism, and hypothyroidism may occur. Given the rapid advancements in this field and the variability in patient outcomes, there is an urgent need for a comprehensive review that consolidates the latest findings on immune checkpoint inhibitors, covering their clinical status, biomarkers, resistance mechanisms, strategies to overcome resistance, and associated adverse effects. This review aims to fill this gap by providing an analysis of the current clinical status of ICIs, emerging biomarkers, mechanisms of resistance, strategies to enhance therapeutic efficacy, and assessment of adverse effects. This review is crucial to furthering our understanding of ICIs and optimizing their application in cancer therapy.

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 a prevalent malignant tumour worldwide. Depending on the stage of the tumour and liver function, a variety of treatment options are indicated. Traditional radiotherapy and chemotherapy are ineffective against HCC; however, the U.S. Food and Drug Administration (FDA) has approved radiofrequency ablation (RFA), surgical resection, and transarterial chemoembolization (TACE) for advanced HCC. On the other hand, liver transplantation is recommended in the early stages of the disease. Tyrosine kinase inhibitors (TKIs) like lenvatinib and sorafenib, immunotherapy and anti-angiogenesis therapy, including pembrolizumab, bevacizumab, tremelimumab, durvalumab, camrelizumab, and atezolizumab, are other treatment options for advanced HCC. Moreover, to maximize outcomes for patients with HCC, the combination of immune checkpoint inhibitors (ICIs) along with targeted therapies or local ablative therapy is being investigated. This review elaborates on the current status of HCC treatment, outlining the most recent clinical study results and novel approaches.

In Asia-Pacific region, hepatocellular carcinoma is a serious health threat attributing to over 600,000 deaths each year and account for over 70% of global cases. Clinically, the major unmet needs are recurrence after curative-intent surgery, liver transplantation or local ablation and disease progression in those with hepatocellular carcinoma not eligible for resection or failed locoregional therapy. In the recent few years, new targeted therapy and immune-checkpoint inhibitors have been registered as systemic therapy to address these issues. Notably, new forms of systemic therapy, either as first-line or second-line therapy for unresectable hepatocellular or those not eligible for locoregional therapy, are now available. New data is also emerging with the use of systemic therapy to prevent hepatocellular carcinoma recurrence after curative-intent resection or local ablation therapy and to retard disease progression after locoregional therapy. In the future, further implementation of immune-checkpoint inhibitors and other forms of immunotherapy are expected to bring a new paradigm to the management of hepatocellular carcinoma. New insight related to immune-related adverse events with the use of immunotherapy has allso enabled optimization of the therapeutic approach to patients with hepatocellular carcinoma. The purpose of this clinical practice guideline is to provide an up-to-date recommendation based on clinical evidence and experience from expert Asia-Pacific key opinion leaders in the field of hepatocellular carcinoma. Three key questions will be addressed, namely: (1) Which patients with hepatocellular carcinoma should be considered for systemic therapy? (2) Which systemic therapy should be used? (3) How should a patient planned for immune checkpoint-based systemic therapy be managed and monitored?

Hepatocellular carcinoma (HCC), the most common primary liver cancer, is a major cause of cancer-related morbidity and mortality. Limited treatment options for advanced stages highlight the need for effective therapies.

This review explores immune checkpoint inhibitors (ICIs), specifically PD-1, PD-L1, and CTLA-4 inhibitors, as emerging treatments for advanced HCC. It discusses data from phase II and III trials evaluating ICI combinations with tyrosine kinase inhibitors (TKIs), anti-angiogenic agents, and locoregional treatments like Transarterial Chemoembolization (TACE). Clinical outcomes, including progression-free survival and response rates, were analyzed alongside the incidence and management of immune-related adverse events (irAEs). A systematic review approach ensured comprehensive, high-quality study inclusion.

ICI-based therapies and their combinations are transforming advanced HCC treatment, offering improved outcomes and potential survival benefits. However, these therapies need optimization in sequencing and selection, particularly considering variations in liver function and disease stage. Effective management of adverse effects is critical to maximize clinical benefits. Further research is required to develop personalized strategies, tailoring treatments to patient-specific factors and enhancing safety and effectiveness in HCC management.

For patients with advanced or unresectable hepatocellular carcinoma (HCC), safe and effective therapies are urgently needed to improve their long-term prognosis. Although the guidelines recommend first-line treatments such as sorafenib, lenvatinib, and atezolizumab in combination with bevacizumab (T+A) and second-line treatments such as regorafenib, the efficacy comparison between drugs is lacking, that is, a treatment is not recommended as the optimal or alternative choice for a specific patient population. Therefore, we will conduct a high-quality network meta-analysis based on Phase III randomized controlled trials (RCTs) to systematically evaluate and compare overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and serious adverse events (SAE) of different treatment protocols in the context of first-line and second-line therapies, which are critical for clinical decision making and prognostic improvement in advanced HCC patients.

The studies of interest were Phase III RCTs evaluating the efficacy or safety of first- or second-line therapies in patients with unresectable or advanced HCC. Literature published in English from the four databases of PubMed, Embase, Cochrane Library, and Web of Science was comprehensively searched from the inception to May 23, 2022. Outcomes of interest included OS, PFS, ORR, and SAE. A league table was developed to show the results of the comparison between different treatments. A histogram of cumulative probability was drawn to discuss the ranking probability of treatments based on different outcomes. The effectiveness and safety of various treatments were comprehensively considered and the two-dimensional diagram was plotted to guide clinical practice. The Gemtc package in R Studio was used for network meta-analysis in a Bayesian framework.

The results showed that HAIC-FO was superior to T+A regimen, regardless of OS, PFS or ORR. TACE combined with lenvatinib performed better than T+A in PFS, and ORR. In addition to the T+A regimen, Sintilimab combined with IBI305 and camrelizumab combined with apatinib were also associated with longer OS, PFS, and ORR, and their SAE incidence was not higher than that of T+A, especially for camrelizumab combined with apatinib, its safety was better than that of T+A regimen. There were no new treatments or combinations that were more effective than regorafenib. It was important to note that for PFS, the efficacy of apatinib and cabozantinib was not statistically different from that of regorafenib, so these two treatments could be used as alternative treatment options in cases where regorafenib was not tolerated or treatment failed.

We conducted a network meta-analysis to evaluate the efficacy and safety of multiple treatment modalities by integrating the results of direct and indirect comparisons. This study included high-quality multicenter Phase III RCTs, collated and summarized all treatments involved in advanced or unresectable HCC in first-line and second-line settings, and compared with T+A and regorafenib, respectively, and ranked based on efficacy and safety to support clinical decision making.

Hepatocellular carcinoma (HCC) ranks the sixth most common malignancy but the third leading cause of cancer-related mortality in the world. Significant breakthroughs have been made in systemic treatment for HCC over the past two decades, which have improved treatment outcomes. In addition to multiple tyrosine kinase inhibitors (mTKIs), immune checkpoint inhibitors (ICIs) and antiangiogenic drugs are increasingly being applied. The combination of ICI and antiangiogenic or dual ICIs has become the new standard of care due to remarkable response rates. However, currently available systemic regimens are primarily reserved for certain patients in the intermediate and advanced stages who will not benefit from locoregional treatments. Evidence supporting the use of systemic treatment as neoadjuvant or adjuvant therapies in patients with early-stage HCC, especially the high risk of recurrence after curative treatments, remains limited. This review identified recent developments in systemic therapy, including mTKIs and ICIs, considering results on first- and second-line treatment, role of neoadjuvant and adjuvant settings, and combination with loco-regional therapy. Various ongoing clinical trials regarding the role of systemic therapies and potential novel targets in patients with early-, intermediate-, and advanced-stage HCC were also summarized and revealed that systemic therapy is no longer limited to advanced-stage HCC. Moreover, the introduction of T-cell redirecting strategies, including bispecific antibodies and chimeric antigen receptor T cells, has revolutionized the treatment landscape for HCC. Future research should focus on an in-depth exploration of the mechanisms governing the establishment of tumor barriers.

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.

We aimed to characterize quality of life (QOL) trajectories among patients with intermediate and advanced hepatocellular carcinoma patients treated with immunotherapy.

Barcelona Clinic Liver Cancer (BCLC) stage B-C HCC patients receiving immunotherapy at Guangxi Medical University Cancer Hospital were included. Trajectories of QOL, assessed using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire, were identified through iterative estimations of group-based trajectory models. Associations with trajectory group membership were analyzed using multivariable multinomial logistic regression.

Three trajectory groups were identified (n=156): excellent (35.3%), poor (43.6%), and deteriorating (21.1%) QOL. The deteriorating trajectory group reported a mean QOL score of 124.79 (95% CI, 116.58-133.00), but then declined significantly at month-2 (estimated QOL score 98.67 [95% CI, 84.33-113.00]), and the lowest mean score is reached at month-6 (estimated QOL score 16.58 [95% CI, 0-46.07]). Factors associated with membership to the deteriorating group included no drinking (odds ratio [OR] vs yes [95% CI], 3.70 [1.28-11.11]), no received radiotherapy (OR vs yes [95% CI], 8.33 [1.41-50.00]), diabetes (OR vs no [95% CI], 6.83 [1.57-29.73]), and extrahepatic metastasis (OR vs no [95% CI], 3.08 [1.07-8.87]). Factors associated with membership to the poor group also included body mass index ≤24.0 kg/m2 (OR vs no [95% CI], 4.49 [1.65-12.22]).

This latent-class analysis identified a high-risk cluster of patients with severe, persistent post-immunotherapy QOL deterioration. Screening relevant patient-level characteristics may inform tailored interventions to mitigate the detrimental impact of immunotherapy and preserve QOL.
