Use of Hepatocellular Carcinoma Surveillance in Patients With Cirrhosis: A Systematic Review and Meta-Analysis

Current impact in the treatment of advanced hepatocellular carcinoma: The challenge remains

Hepatocellular carcinoma remains a significant cause of mortality worldwide, particularly among patients with liver cirrhosis. In most cases, surveillance in cirrhotic patients is neglected, leading to a diagnosis when the neoplasm is at an advanced stage. Within this context, Zhou et al carried out a network meta-analysis to demonstrate the effectiveness of hepatic arterial infusion chemotherapy, concluding that it is a superior approach compared to sorafenib and transarterial chemoembolization in the treatment of advanced hepatocellular carcinoma. Unfortunately, the meta-analysis in question lacks methodological rigor, preventing the authors from making more definitive assertions. Additionally, we understand that transarterial chemoembolization, when properly indicated, is a highly effective therapeutic option, and that sorafenib, given the results of new therapies based on immune checkpoint inhibitors, is no longer the recommended drug for the treatment of these patients. Therefore, we believe the use of hepatic arterial infusion chemotherapy is increasingly limited and lacks strong scientific support.

Health inequalities in hepatocellular carcinoma surveillance, diagnosis, treatment, and survival in the United Kingdom: a scoping review

BACKGROUND

Hepatocellular carcinoma (HCC) remains a deadly cancer in the UK despite advancements in curative therapies. Societal conditions and health inequalities influence the development of chronic liver disease and outcomes from complications including HCC. Scoping this emergent evidence-base is required to inform research and solutions for the NHS.

METHODS

A PRISMA scoping review was performed up to September 2023. Articles exploring health inequalities in HCC involving the UK population were included.

RESULTS

This review has characterised axes of health inequality and their impact across the HCC care continuum in the UK. Studies predominantly employed a cohort design or population-based analyses, with meta-analyses of surveillance utilisation including only a single UK study. These methodologies provided an appropriate lens to understand longitudinal trends and identify disadvantaged groups. However, important evidence gaps remain, including exploration of patient perspectives, intersectional analyses, and statistical measures of socioeconomic inequity in HCC.

CONCLUSIONS

HCC is a rapidly growing cause of cancer mortality and disproportionally affects underserved groups, presenting a major public health concern. Further research is required to innovate and evaluate surveillance and management pathways to reduce systemic inequities. Direction is needed at the national level to improve prevention, early diagnosis and access to curative treatment.

Dedicated Automatic Recall Hepatocellular Cancer Surveillance Programme Demonstrates High Retention: A Population-Based Cohort Study

INTRODUCTION

Patient, clinician, and system-related barriers may affect adherence to hepatocellular carcinoma (HCC) surveillance programmes. The impact of a dedicated automated recall HCC surveillance programme on retention rates in patients eligible for screening is unknown. We aimed to describe and evaluate a large HCC surveillance programme in a publicly funded healthcare system.

METHODS

Data were collected from January 1, 2013, to December 31, 2022, from a retrospective cohort of subjects enrolled in a publicly funded automated recall semi-annual surveillance programme as per the American Association for the Study of Liver Disease HCC guidance in the Calgary Health Zone (~1.6 million), Canada. Patients were excluded if there was incomplete data or did not meet indications for surveillance. Cox regression was used to identify predictors of non-retention to surveillance.

RESULTS

A total of 7269 patients were included. The median was age 55.5 years (IQR: 45.5-63.8), 60% were male, 46% were of Asian descent, 51% had HBV infection, and 36% had cirrhosis (35% alcohol-related). Median follow-up was 4.9 years (IQR: 1.5-7.2). Overall, 52% (n = 3768) of patients were retained in the surveillance programme, while 8.3% (n = 603) left for potential medical reasons, and 40% (n = 2898) were lost in follow-up. The median time in the programme for those lost in follow-up was 0.81 years (IQR: 0.0-2.8) compared to 6.75 years if retained (IQR: 5.6-8.6; p < 0.001). In multivariable Cox regression analysis, HCV aetiology (HR 1.41; CI 1.23-1.62, p < 0.01), African ethnicity (HR 1.20, CI 1.02-1.42, p = 0.03), and cirrhosis (HR 1.16, CI 1.05-1.28, p < 0.01) increased risk of dropout. On interaction analysis, Hepatitis B amongst cirrhotic patients also increased risk of dropout (HR 1.48, CI 1.05-2.07, p = 0.02).

CONCLUSION

A dedicated automated recall HCC surveillance programme has a high retention rate in a large multi-ethnic cohort of patients while identifying certain marginalised patient populations, such as those with viral liver disease, cirrhosis, or African ethnicity, as particularly vulnerable to loss to follow-up.

Cost-effectiveness of an outreach program for HCC screening in patients with cirrhosis: a microsimulation modeling study

Background

Patients with cirrhosis are at high risk for hepatocellular carcinoma (HCC), but few undergo guideline-recommended semi-annual screening. Randomized clinical trials (RCTs) demonstrate that mailed outreach can increase screening versus visit-based screening. We estimated the costs and cost-effectiveness of an outreach strategy versus usual care.

Methods

We built a 10-year Markov chain Monte Carlo microsimulation model to conduct a cost-effectiveness analysis comparing a mailed outreach program versus usual care for HCC screening in a cohort of 10,000 patients with cirrhosis. Model inputs were based on literature review (2005-current), and costs were based on inflation-adjusted estimates from Surveillance, Epidemiology, and End Results (SEER)-Medicare claims data. We conducted one-way sensitivity analyses for HCC incidence, outreach costs, efficacy of the outreach strategy to increase screening, and efficacy of curative (versus palliative) HCC treatments.

Findings

Mailed outreach was estimated to cost $32.45 per patient in the first year and $21.90 per patient in subsequent years. The outreach program increased the number of HCC patients detected at an early stage by 48.4% and increased quality-adjusted life years (QALYs) by 300. Cost savings from these increases offset the costs of mailed outreach. Mailed outreach remained cost-effective across a wide range of HCC incidence rates, outreach costs, efficacy of the outreach strategy to increase screening, and the efficacy of curative HCC treatments. Annual out-of-pocket patient costs in the outreach arm were low at $13 per year.

Interpretation

Mailed outreach to encourage HCC screening in patients with cirrhosis dominates usual care and should be considered for implementation in routine practice.

Alcohol-Related Liver Disease, Followed by Metabolic Dysfunction-Associated Steatotic Liver Disease, Emerges as the Fastest-Growing Aetiologies for Primary Liver Cancer in the United States

OBJECTIVE

Primary liver cancer (PLC) is projected to be the third leading cause of cancer mortality in the United States in 2040. We examine the burden of PLC in the United States, stratified by sex, state and aetiological risk factors.

METHODS

Data on PLC prevalence, incidence, death and disability-adjusted life years (DALYs) were extracted from the Global Burden of Disease Study 2021. Changes in these parameters were calculated using the Joinpoint regression model.

RESULTS

There were 47,970 cases, 31,450 incident cases, 24,770 deaths and 576,920 DALYs from PLC in the United States. The highest prevalence (16,980), incidence (12,040), death (9840) and DALYs (213,410) from PLC were due to chronic hepatitis C virus infection. From 2000 to 2021, PLC incidences increased by 141%, and PLC deaths increased by 136%. Age-standardised incidence rates (ASIRs) and death rates (ASDRs) per 100,000 population for PLC increased, primarily driven by alcohol-related liver disease (ALD) (ASIR: annual percent change [APC]: +2.40%; ASDR: APC: +2.22%) and metabolic dysfunction-associated steatotic liver disease (MASLD) (ASIR: APC: +2.32%; ASDR: APC: +2.04%).

CONCLUSION

The burden of PLC in the United States has risen in the past two decades, driven mainly by ALD and followed by MASLD. These findings offer policymakers an accurate assessment of the PLC burden and emphasise the need for targeted risk factor mitigation, especially regarding alcohol related policy.

Phase 3 Validation of PAaM for Hepatocellular Carcinoma Risk Stratification in Cirrhosis

BACKGROUND & AIMS

Hepatocellular carcinoma (HCC) risk stratification is an urgent unmet need for cost-effective HCC screening and early detection in patients with cirrhosis to improve poor HCC prognosis.

METHODS

Molecular (prognostic liver secretome signature with α-fetoprotein) and clinical (aMAP [age, male sex, albumin-bilirubin, and platelets] score) variable-based scores were integrated into PAaM (prognostic liver secretome signature with α-fetoprotein plus age, male sex, albumin-bilirubin, and platelets), which was subsequently validated in 2 phase 3 biomarker validation studies: the statewide Texas HCC Consortium and nationwide HCC Early Detection Strategy prospective cohorts, following the prospective specimen collection, retrospective blinded evaluation design. The associations between baseline PAaM and incident HCC were assessed using Fine-Gray regression, with overall death and liver transplantation as competing events.

RESULTS

Of 2156 patients with cirrhosis in the Texas HCC Consortium, PAaM identified 404 (19%) high-risk, 903 (42%) intermediate-risk, and 849 (39%) low-risk patients with annual HCC incidence rates of 5.3%, 2.7%, and 0.6%, respectively. Compared with low-risk patients, high- and intermediate-risk groups had sub-distribution hazard ratios for incident HCC of 7.51 (95% CI, 4.42-12.8) and 4.20 (95% CI, 2.52-7.01), respectively. Of 1328 patients with cirrhosis in the HCC early detection strategy, PAaM identified 201 high-risk (15%), 540 intermediate-risk (41%), and 587 low-risk (44%) patients, with annual HCC incidence rates of 6.2%, 1.8%, and 0.8%, respectively. High- and intermediate-risk groups were associated with sub-distribution hazard ratios for incident HCC of 6.54 (95% CI, 3.85-11.1) and 1.77 (95% CI, 1.02-3.08), respectively. Subgroup analysis showed robust risk stratification across HCC etiologies, including metabolic dysfunction-associated steatotic liver disease and cured hepatitis C infection.

CONCLUSIONS

PAaM enables accurate HCC risk stratification in patients with cirrhosis from contemporary etiologies.

Persisting challenges in the early detection of hepatocellular carcinoma

INTRODUCTION

Prognosis in patients with HCC is largely determined by stage at diagnosis, highlighting the importance of effective early detection strategies. HCC surveillance is associated with increased early detection and reduced HCC-related mortality and is currently recommended in patients with cirrhosis or chronic HBV infection.

AREAS COVERED

We performed a targeted literature review to identify limitations of current HCC surveillance practices and strategies for improvement.

EXPERT OPINION

Semi-annual ultrasound continues as the cornerstone modality for HCC surveillance but has limited sensitivity for detecting early-stage HCC, particularly in patients with obesity and non-viral etiologies. Although sensitivity for early-stage HCC can be improved by using ultrasound with alpha fetoprotein, this strategy misses over one-third of HCC at an early stage. Emerging imaging and biomarker-based surveillance strategies currently remain in varying stages of validation and are not yet ready for routine use in practice. The cost-effectiveness of surveillance in patients with non-cirrhotic liver disease related to hepatitis C or metabolic dysfunction-associated steatotic liver disease continues to be debated, although subgroups with advanced fibrosis may warrant surveillance. Finally, the effectiveness of surveillance is diminished by underuse in clinical practice, particularly in racial minority and low-income groups, highlighting a need for interventions to increase utilization.

Innovative Drugs First Implemented in Type 2 Diabetes Mellitus and Obesity and Their Effects on Metabolic Dysfunction-Associated Steatohepatitis (MASH)-Related Fibrosis and Cirrhosis

Metabolic dysfunction-associated steatotic liver disease (MASLD), a progressive liver disease frequently associated with metabolic disorders such as type 2 diabetes mellitus (T2DM) and obesity, has the potential to progress symptomatically to liver cirrhosis and, in some cases, hepatocellular carcinoma. Hence, an urgent need arises to identify and approve new therapeutic options to improve patient outcomes. Research efforts have focused on either developing dedicated molecules or repurposing drugs already approved for other conditions, such as metabolic diseases. Among the latter, antidiabetic and anti-obesity agents have received the most extensive attention, with pivotal trial results anticipated shortly. However, the primary focus underlying successful regulatory approvals is demonstrating a substantial efficacy in improving liver fibrosis and preventing or ameliorating cirrhosis, the key advanced outcomes within MASLD progression. Besides liver steatosis, the ideal therapeutic candidate should reduce inflammation and fibrosis effectively. Although some agents have shown promise in lowering MASLD-related parameters, evidence of their impact on fibrosis and cirrhosis remains limited. This review aims to evaluate whether antidiabetic and anti-obesity drugs can be safely and effectively used in MASLD-related advanced fibrosis or cirrhosis in patients with T2DM. Our paper discusses the molecules closest to regulatory approval and the expectation that they can address the unmet needs of this increasingly prevalent disease.

Significant Disparities in Hepatocellular Carcinoma Outcomes by Race/Ethnicity and Sociodemographic Factors

BACKGROUND

Hepatocellular carcinoma (HCC) disproportionately affects racial/ethnic minorities. We evaluated the impact of income and geography on racial/ethnic disparities across the HCC care cascade in the United States.

METHODS

Using NCI registry data spanning 2000 to 2020, adults with HCC were evaluated to determine race/ethnicity-specific differences in tumor stage at diagnosis, delays and gaps in treatment, and survival. Adjusted regression models evaluated predictors of HCC outcomes.

RESULTS

Among 112,389 adults with HCC, cohort characteristics were as follows: 49.8% non-Hispanic White (NHW), 12.0% African American(AA), 20.5% Hispanic, 16.5% Asian/Pacific Islander, and 1.1% American Indian/Alaska Native. Compared with NHW patients, AA patients had lower odds of localized-stage HCC at diagnosis [adjusted odds ratio (aOR), 0.84], lower odds of HCC treatment receipt (aOR, 0.77), greater odds of treatment delays (aOR, 1.12), and significantly greater risk of death [adjusted hazards ratio (aHR), 1.10]. Compared with NHW patients from large metro areas, AA patients from large metro areas had 8% higher mortality risk (aHR, 1.08), whereas AA patients from small-medium metro areas had 17% higher mortality risk (aHR, 1.17; all P < 0.05).

CONCLUSIONS

Among a population-based cohort of US adults with HCC, significant race/ethnicity-specific disparities across the HCC care continuum were observed. Lower household income and more rural geography among racial/ethnic minorities are also associated with disparities in HCC outcomes, particularly among AA patients.

IMPACT

Our study shows that lower income and less urban/more rural geography among racial/ethnic minorities are also associated with disparities in HCC outcomes, particularly among AA patients with HCC. This contextualizes the complex relationship between sociodemographic factors and HCC outcomes through an intersectional lens.

Benefits and harms of hepatocellular carcinoma screening outreach in patients with cirrhosis: a multicenter randomized clinical trial

BACKGROUND

The value of hepatocellular carcinoma screening is defined by the balance of benefits from early tumor detection vs harms because of false-positive results. We evaluated the value of a mailed outreach strategy for hepatocellular carcinoma screening in patients with cirrhosis.

METHODS

We conducted a multicenter pragmatic randomized clinical trial comparing mailed outreach for hepatocellular carcinoma screening (n = 1436) and usual care with visit-based screening (n = 1436) among patients with cirrhosis at 3 health systems from March 2018 to September 2021. Outcomes of interest were early stage hepatocellular carcinoma detection (ie, screening benefit) and diagnostic evaluation for false-positive or indeterminate results (ie, screening harm). Screening harm was categorized as mild, moderate, and severe based on number and type of diagnostic exams. All patients were included in intention-to-screen analyses.

RESULTS

Of 125 patients diagnosed with hepatocellular carcinoma (67 outreach and 58 usual care), 71.2% were found at an early stage per the Milan criteria. Early tumor detection did not statistically significantly differ between the outreach and usual care arms (64.2% vs 79.3%; P = .06). The proportion of patients with physical harms also did not differ between the outreach and usual care arms (10.8% vs 10.7%; P = .95) with 5.9% in both arms having mild harms; 4.0% and 3.8%, respectively, with moderate harms; and 0.9% and 1.0%, respectively, with severe harms.

CONCLUSION

Most patients enrolled in hepatocellular carcinoma screening were detected at an early stage, and a minority experienced physical harms. A mailed outreach strategy did not increase early hepatocellular carcinoma detection or physical harms compared with usual care.

The importance of equity in transplant oncology

PURPOSE OF REVIEW

Transplant oncology encompasses and utilizes liver transplantation (LT) in combination with other aspects of cancer care to offer improved long-term outcomes for patients with liver cancer, but not all patients have equal access and ability to undergo LT. Social determinants of health may negatively impact a patient's ability to receive liver-related oncologic care, including LT. This review highlights recent work exposing gaps in access to LT, including transplant oncology, and interventions to ameliorate these disparities.

RECENT FINDINGS

Members of racial and ethnic minorities and indigenous groups, females, socioeconomically disadvantaged persons, and patients from rural areas are less likely to undergo LT. Recent studies have also described programs that have successfully mitigated some of the barriers in access to transplant oncology that these patients experience, including targeted outreach programs and access to virtual healthcare.

SUMMARY

Disparities in access to LT for liver cancer are increasingly well described, but additional research is needed to find effective ways to ameliorate these differences.

A Phase 3 Biomarker Validation of GALAD for the Detection of Hepatocellular Carcinoma in Cirrhosis

BACKGROUND & AIMS

Better surveillance tests for hepatocellular carcinoma (HCC) are needed. The GALAD score (gender, age, α-fetoprotein [AFP] L3, AFP, and des-γ carboxyprothrombin) has been shown to have excellent sensitivity and specificity for HCC in phase 2 studies. We performed a phase 3 biomarker validation study to compare GALAD with AFP in detecting HCC.

METHODS

This is a prospective study of patients with cirrhosis enrolled at 7 centers. Surveillance for HCC was performed every 6 months at each site, and HCC diagnosis was confirmed per American Association for the Study of Liver Diseases guidelines. Blood for biomarker research was obtained at each follow-up visit and stored in a biorepository. Measurements of AFP, AFP-L3, and des-γ carboxyprothrombin) were performed in a FujiFilm laboratory by staff blinded to clinical data. The performance of GALAD in detecting HCC was retrospectively evaluated within 12 months before the clinical diagnosis. All analyses were conducted by an unblinded statistician in the Early Detection Research Network data management and coordinating center.

RESULTS

A total of 1,558 patients with cirrhosis were enrolled and followed for a median of 2.2 years. A total of 109 patients developed HCC (76 very early or early stage), with an annual incident rate of 2.4%. The areas under the curve for AFP and GALAD within 12 months before HCC were 0.66 and 0.78 (P < .001), respectively. Using a cutoff for GALAD of -1.36, the specificity was 82%, and the sensitivity at 12 months before HCC diagnosis was 62%. For comparison, performance of AFP at 82% specificity showed 41% sensitivity at 12 months before HCC diagnosis (P = .001).

CONCLUSIONS

GALAD score, compared to AFP, improves the detection of HCC within 12 months before the actual diagnosis.

Clinical Applications of Artificial Intelligence (AI) in Human Cancer: Is It Time to Update the Diagnostic and Predictive Models in Managing Hepatocellular Carcinoma (HCC)?

In recent years, novel findings have progressively and promisingly supported the potential role of Artificial intelligence (AI) in transforming the management of various neoplasms, including hepatocellular carcinoma (HCC). HCC represents the most common primary liver cancer. Alarmingly, the HCC incidence is dramatically increasing worldwide due to the simultaneous "pandemic" spreading of metabolic dysfunction-associated steatotic liver disease (MASLD). MASLD currently constitutes the leading cause of chronic hepatic damage (steatosis and steatohepatitis), fibrosis, and liver cirrhosis, configuring a scenario where an HCC onset has been reported even in the early disease stage. On the other hand, HCC represents a serious plague, significantly burdening the outcomes of chronic hepatitis B (HBV) and hepatitis C (HCV) virus-infected patients. Despite the recent progress in the management of this cancer, the overall prognosis for advanced-stage HCC patients continues to be poor, suggesting the absolute need to develop personalized healthcare strategies further. In this "cold war", machine learning techniques and neural networks are emerging as weapons, able to identify the patterns and biomarkers that would have normally escaped human observation. Using advanced algorithms, AI can analyze large volumes of clinical data and medical images (including routinely obtained ultrasound data) with an elevated accuracy, facilitating early diagnosis, improving the performance of predictive models, and supporting the multidisciplinary (oncologist, gastroenterologist, surgeon, radiologist) team in opting for the best "tailored" individual treatment. Additionally, AI can significantly contribute to enhancing the effectiveness of metabolomics-radiomics-based models, promoting the identification of specific HCC-pathogenetic molecules as new targets for realizing novel therapeutic regimens. In the era of precision medicine, integrating AI into routine clinical practice appears as a promising frontier, opening new avenues for liver cancer research and treatment.

Prevention of liver cancer in the era of next-generation antivirals and obesity epidemic

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly HCC and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease. Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients. The recent development of new therapeutic agents and modalities has opened unprecedented opportunities to refine primary, secondary, and tertiary HCC prevention strategies. For primary prevention (before exposure to risk factors), public health policies, such as universal HBV vaccination, have had a substantial prognostic impact. Secondary prevention (after or during active exposure to risk factors) includes regular HCC screening and chemoprevention. Emerging biomarkers and imaging modalities for HCC risk stratification and detection may enable individual risk-based personalized and cost-effective HCC screening. Clinical studies have suggested the potential utility of lipid-lowering, antidiabetic/obesity, and anti-inflammatory agents for secondary prevention, and some of them are being evaluated in prospective clinical trials. Computational and experimental studies have identified potential chemopreventive strategies directed at diverse molecular, cellular, and systemic targets for etiology-specific and/or agnostic interventions. Tertiary prevention (in conjunction with curative-intent therapies for HCC) is an area of active research with the development of new immune-based neoadjuvant/adjuvant therapies. Cholangiocarcinoma prevention may advance with recent efforts to elucidate risk factors. These advances will collectively lead to substantial improvements in liver cancer mortality rates.

Synthesising enablers and barriers to hepatocellular carcinoma surveillance-A systematic review of qualitative findings

BACKGROUND & AIMS

This systematic literature review of qualitative findings aims to identify the perceived barriers and enablers for hepatocellular carcinoma (HCC) surveillance from patient and clinician perspectives.

METHODS

A systematic search of databases using key term combinations with the following inclusion criteria: 1) qualitative and quantitative (survey) studies exploring barriers and enablers of HCC surveillance, and 2) qualitative and quantitative (survey) studies exploring barriers and enablers of enagagement in clinical care for patients with cirrhosis and/or viral hepatitis.

RESULTS

The search returned 445 citations: 371 did not meet the study criteria and were excluded. 74 studies proceeded to full-text review, leading to 21 included studies (15 studies from searching with a further six studies from citation review) progressing to data extraction by two independent reviewers. Results from studies exploring patients' perspectives reinforce that barriers are experienced by patients across different health settings, cultures, and regions. Logistical barriers including costs and transportation, and knowledge/awareness barriers were commonly identified. Studies that included clinician perspectives highlighted the need for healthcare provider education and system-level interventions to optimize HCC surveillance uptake in clinical practice.

CONCLUSION

These findings highlight the critical need for interventions that enable engagement in HCC surveillance in health services.

Outcomes of radiofrequency ablation for hepatocellular carcinoma with concurrent steatotic liver disease

BACKGROUND

Steatotic liver disease (SLD) is an emerging liver disease that has been associated with an increased risk for hepatocellular carcinoma (HCC). The impact of concurrent SLD on the prognosis of HCC remains unknown. This study investigates how concurrent SLD affects the outcomes of patients with HCC undergoing curative radiofrequency ablation (RFA) therapy.

METHODS

A retrospective analysis of patients with early-stage HCC receiving curative RFA at a tertiary medical center was conducted. Laboratory data and HCC characteristics were recorded and analyzed by a Cox proportional hazards regression model to predict recurrence and all-cause mortality after RFA.

RESULTS

A total of 598 patients with HCC were included between 2005 and 2015, with 139 and 459 classified in SLD and non-SLD groups, respectively. The SLD group exhibited a significantly better liver reserve and a lower cumulative incidence of HCC recurrence and liver-related and all-cause mortality after a median follow-up of 51 months. After adjusting for metabolic dysfunction, liver reserve, and HCC characteristics, the presence of SLD reduced all-cause mortality (adjusted hazard ratio [aHR], 0.67; 95% confidence interval [CI], 0.45-0.996; p = .048), which was supported by inverse probability weighting analysis (aHR, 0.65; 95% CI, 0.42-1.00; p = .049). Poor liver functional reserve (high albumin-bilirubin grades) increased all-cause mortality dose dependently. Barcelona Clinic Liver Cancer staging and a higher Fibrosis-4 index were predictors for HCC recurrence, whereas SLD was not.

CONCLUSIONS

Among patients with HCC undergoing curative RFA, those with concurrent SLD had a lower risk of all-cause mortality compared to those with poor liver functional reserve.

PLAIN LANGUAGE SUMMARY

The present research demonstrated that patients with both liver cancer and steatotic liver disease who received curative radiofrequency ablation for liver cancer survived longer compared to those without steatotic liver disease. Maintaining good liver function is an important prognostic factor for survival.

Differences between hepatocellular carcinoma caused by alcohol and other aetiologies

Alcohol-related liver disease is the third cause of hepatocellular carcinoma worldwide and the leading cause in Europe. Additionally, the recent definition of Metabolic dysfunction-Associated Steatotic Liver Disease with increased alcoholic intake will enrich this population with a more nuanced phenotype, reflecting recent epidemiological trends. In these patients, hepatocellular carcinoma diagnosis is often delayed and less frequently detected through screening programs. Moreover, at the time of diagnosis, patients with alcohol-related hepatocellular carcinoma tend to have a poorer general condition, more severely impaired liver function, and a higher prevalence of comorbidities, leading to increased competitive mortality. However, when hepatocellular carcinoma is diagnosed during surveillance programs in patients with alcohol-related liver disease or metabolic dysfunction-Associated steatotic liver disease with increased alcoholic intake, the rate of allocation to first-line curative treatments is high (56%) and comparable to that of patients with virus-related hepatocellular carcinoma. As a consequence, the etiology of the underlying cirrhosis cannot be considered an independent prognostic factor in patients with hepatocellular carcinoma. Instead, prognosis is driven by liver function, general condition, and tumor burden. This underscores the crucial role of early diagnosis through periodic surveillance in patients with Alcohol-related liver disease or Metabolic dysfunction-Associated Steatotic Liver Disease with increased alcoholic intake -related cirrhosis.

GALAD, or des-gamma-carboxy prothrombin compared with alpha-foetoprotein for the diagnosis of hepatocellular carcinoma in people with chronic liver disease

OBJECTIVES

This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To estimate the diagnostic accuracy of des-gamma-carboxy prothrombin, GALAD (Gender, Age, Lens culinaris agglutinin-reactive AFP, AFP and DCP), and alpha-foetoprotein for the diagnosis of hepatocellular carcinoma of any size, and at any stage, in adults with chronic liver disease, in either a surveillance programme or a clinical setting. We acknowledge the possibility that theoretically, the accuracy of the tests in a surveillance programme may differ from that in a clinical setting due to variation in inclusion criteria and the prevalence of the target condition. However, we do not plan a separate analysis for surveillance and clinical settings, as they are not clearly distinct in current clinical practice (Forner 2018; Poustchi 2011). In routine evaluation of people with chronic liver disease, index tests, as well as ultrasound, are already part of standard procedure. Given that HCC typically presents with no symptoms and is often asymptomatic, suspicion of the disease is typically based solely on the presence of advanced chronic liver disease. However, we do plan to consider the study setting as a potential source of heterogeneity. To compare the diagnostic accuracy of des-gamma-carboxy prothrombin (DCP) alone or GALAD alone versus alpha-foetoprotein (AFP), for the diagnosis of hepatocellular carcinoma (HCC) of any size, at any stage; in adults with chronic liver disease, either in a surveillance programme or a clinical setting. Secondary objectives To estimate the diagnostic accuracy of DCP or GALAD versus AFP, for resectable HCC in people with chronic liver disease, in a surveillance programme and a clinical setting. To investigate the following predefined sources of heterogeneity for each of the index tests: study design (case-control studies compared to cross-sectional studies); inclusion of participants without cirrhosis (studies including more than 10% of participants without cirrhosis compared to studies including less than 10% of participants without cirrhosis); study location (population differences): studies conducted in North and South America and Europe compared to Asia and Africa; prevalence of the target condition (studies with hepatocellular carcinoma prevalence more than 10% compared to studies with hepatocellular carcinoma prevalence less than 10%); participant selection (participants recruited from planned surveillance programmes compared to clinical cohorts); different reference standards (histology of the explanted liver compared to liver biopsy compared to another reference standard); different aetiology: studies including at least 90% of participants with chronic viral hepatitis compared to studies including less than 90% of participants with chronic viral hepatitis.

Cost-Effectiveness of a Biomarker-Based Screening Strategy for Hepatocellular Carcinoma in Patients with Cirrhosis

Introduction

Given suboptimal performance of ultrasound-based surveillance for early hepatocellular carcinoma (HCC) detection in patients with cirrhosis, there is interest in alternative surveillance strategies, including blood-based biomarkers. We aimed to evaluate the cost-effectiveness of biomarker-based surveillance in patients with cirrhosis.

Methods

We constructed a decision-analytic model to compare ultrasound/alpha-fetoprotein (AFP) and biomarker-based surveillance strategies in 1,000,000 simulated patients with compensated cirrhosis. Model inputs for adherence, benefits, and harms of each strategy were based on literature review, and costs were derived from the Medicare fee schedule. Primary outcomes were quality-adjusted life-years (QALY) and incremental cost-effectiveness ratio (ICER) of the surveillance strategies, with cost-effectiveness assessed at a threshold of USD 150,000 per QALY. We performed sensitivity analyses for HCC incidence, test performance characteristics, surveillance adherence, and biomarker costs.

Results

In the base case, both ultrasound/AFP and biomarker-based surveillance were cost-effective versus no surveillance, with ICERs of USD 105,620, and USD 101,295, per QALY, respectively. Biomarker-based surveillance was also cost-effective versus ultrasound/AFP, with an ICER of USD 14,800 per QALY. Biomarker sensitivity exceeding 80%, cost below USD 210, or adherence exceeding 58% were necessary for biomarker-based screening to be cost-effective versus ultrasound/AFP. In two-way sensitivity analyses, biomarker costs were directly related with test sensitivity and adherence, whereas sensitivity and adherence were inversely related. In a probabilistic sensitivity analysis, biomarker-based screening was the most cost-effective strategy in most (65%) simulations.

Conclusion

Biomarker-based screening appears cost-effective for HCC screening, but results are sensitive to test sensitivity, adherence, and costs.

Oncological outcomes of tumor ablation compared to surgical resection in early-stage hepatocellular carcinomas: a systematic review with meta-analysis

BACKGROUND

The optimal choice of treatment for early-stage hepatocellular carcinomas (HCC) remains controversial, with recent conflicted guidelines. This systematic review evaluated whether ablation is oncologically non-inferior to surgical resection.

METHODS

We performed a systematic search of the EMBASE, MEDLINE, CENTRAL and Web of Science databases to identify randomized controlled trials comparing tumor ablation and surgical resection for early-stage HCCs. A non-inferiority margin of 5% (RR 0.93) for overall survival (OS) was considered, following a consensus of clinical experts.

RESULTS

We identified 5829 citations from which 11 trials (n = 1736) were included. The non-inferiority of tumor ablation was not observed for OS (RR 0.92; 95%CI 0.85-1.00,I2 = 33%). Recurrence-free survival was reduced with ablation (RR 0.80; 95%CI 0.69-0.93,I2 = 49%). There was no difference in terms of extra-hepatic recurrence and minor complications. Tumor ablation was associated with decreased overall morbidity (RR 0.43; 95%CI 0.30-0.62,I2 = 31%) and major complications (RR 0.22; 95%CI 0.07-0.71,I2 = 66%). Intra-hepatic recurrence was higher with ablation (RR 1.28; 95%CI 1.10-1.48,I2 = 12%). Certainty of evidence was low to moderate.

CONCLUSION

We did not observe the oncological non-inferiority of tumor ablation when compared to surgical resection. Nevertheless, most analyses were of low quality of evidence, including the overall survival. We cannot exclude that the true effect of tumor ablation is different than the currently observed one.

Liver diseases and hepatocellular carcinoma in the Asia-Pacific region: burden, trends, challenges and future directions

Globally, nearly half of deaths from cirrhosis and chronic liver diseases (CLD) and three-quarters of deaths from hepatocellular carcinoma (HCC) occur in the Asia-Pacific region. Chronic hepatitis B is responsible for the vast majority of liver-related deaths in the region. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common form of CLD, affecting an estimated 30% of the adult population. Compared with people of European descent, people from the Asia-Pacific region carry more genetic variants associated with MASLD and its progression. Alcohol is a fast-growing cause of CLD and HCC in Asia as a result of the rising per-capita consumption of alcohol. Drug-induced liver injury is under-recognized and probably has a high prevalence in this region. The epidemiological and outcome data of acute-on-chronic liver failure are heterogeneous, and non-unified definitions across regions contribute to this heterogeneity. CLDs are severely underdiagnosed, and effective treatments and vaccinations are underutilized. In this Review, we highlight trends in the burden of CLD and HCC in the Asia-Pacific region and discuss the rapidly changing aetiologies of liver disease. We examine the multiple gaps in the care cascade and propose mitigating strategies and future directions.

Older Age But Not Comorbidity is Associated with Worse Survival in Patients with Hepatocellular Carcinoma

BACKGROUND & AIMS

Age and comorbidity are key factors in assessing patient prognosis and informing stopping rules for cancer screening eligibility, but their impact has not been rigorously evaluated in patients with hepatocellular carcinoma (HCC).

METHODS

We conducted a retrospective cohort study of patients diagnosed with HCC at 2 health systems between January 2010 and February 2023. We used multivariable logistic regression and Cox proportional hazards models to evaluate the associations between older age (≥65 years) and comorbidity burden (Charlson Comorbidity Index) with early-stage presentation, curative treatment receipt, and overall survival. We performed subgroup analyses in patients with early-stage HCC.

RESULTS

We identified 2002 patients with HCC (median age, 61 years; 76% male; 21% early-stage), with a median survival of 15.7 months. In adjusted analyses, curative treatment receipt was associated with higher comorbidity but not older age. Conversely, overall survival was significantly associated with older age (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.06-1.47) but not high comorbidity (HR, 0.92; 95% CI, 0.77-1.09). Older age continued to be associated with worse survival among patients with early-stage HCC (HR, 1.99; 95% CI, 1.45-2.73) and those who underwent curative treatment (HR, 1.52; 95% CI, 1.10-2.10). Median survival for younger versus older individuals was 20 versus 14 months overall, 65 versus 49 months for patients with early-stage HCC, and 113 versus 60 months for those with curative treatment.

CONCLUSIONS

Older age but not comorbidity burden is associated with worse survival, including among patients with early-stage HCC. Further studies are needed to define the role of comorbidity in HCC prognostication.

Effectiveness of mailed outreach and patient navigation to promote HCC screening process completion: a multicentre pragmatic randomised clinical trial

BACKGROUND

Hepatocellular carcinoma (HCC) is plagued by failures across the cancer care continuum, leading to frequent late-stage diagnoses and high mortality. We evaluated the effectiveness of mailed outreach invitations plus patient navigation to promote HCC screening process completion in patients with cirrhosis.

METHODS

Between April 2018 and September 2021, we conducted a multicentre pragmatic randomised clinical trial comparing mailed outreach plus patient navigation for HCC screening (n=1436) versus usual care with visit-based screening (n=1436) among patients with cirrhosis at three US health systems. Our primary outcome was screening process completion over a 36-month period, and our secondary outcome was the proportion of time covered (PTC) by screening. All patients were included in intention-to-screen analyses.

RESULTS

All 2872 participants (median age 61.3 years; 32.3% women) were included in intention-to-screen analyses. Screening process completion was observed in 6.6% (95% CI: 5.3% to 7.9%) of patients randomised to outreach and 3.3% (95% CI: 2.4% to 4.3%) of those randomised to usual care (OR 2.05, 95% CI: 1.44 to 2.92). The intervention increased HCC screening process completion across most subgroups including age, sex, race and ethnicity, Child-Turcotte-Pugh class and health system. PTC was also significantly higher in the outreach arm than usual care (mean 37.5% vs 28.2%; RR 1.33, 95% CI: 1.31 to 1.35). Despite screening underuse, most HCC in both arms were detected at an early stage.

CONCLUSION

Mailed outreach plus navigation significantly increased HCC screening process completion versus usual care in patients with cirrhosis, with a consistent effect across most examined subgroups. However, screening completion remained suboptimal in both arms, underscoring a need for more intensive interventions.

Impact of racial, ethnic, and socioeconomic disparities on presentation and survival of HCC: A multicenter study

BACKGROUND

Racial and ethnic disparities have been reported for HCC prognosis, although few studies fully account for clinically important factors and social determinants of health, including neighborhood socioeconomic status.

METHODS

We conducted a retrospective multicenter cohort study of patients newly diagnosed with HCC from January 2010 through August 2018 at 4 large health systems in the United States. We used multivariable logistic regression and cause-specific Cox proportional hazard models to identify factors associated with early-stage HCC presentation and overall survival.

RESULTS

Of 2263 patients with HCC (37.6% non-Hispanic White, 23.5% non-Hispanic Black, 32.6% Hispanic, and 6.4% Asian/other), 42.0% of patients presented at an early stage (Barcelona Clinic Liver Cancer stage 0/A). In fully adjusted models, there were persistent Black-White disparities in early-stage presentation (OR: 0.63, 95% CI: 0.45-0.89) but not Hispanic-White disparities (OR: 0.93, 95% CI: 0.70-1.24). Median survival was 16.2 (IQR: 5.8-36.8) months for White patients compared to 15.7 (IQR: 4.6-34.4) months for Hispanic, 10.0 (IQR: 2.9-29.0) months for Black, and 9.5 (IQR: 3.4-31.9) months for Asian/other patients. Black-White disparities in survival persisted after adjusting for individual demographics and clinical factors (HR: 1.30, 95% CI: 1.09-1.53) but were no longer observed after adding HCC stage and treatment (HR: 1.05, 95% CI: 0.88-1.24), or in fully adjusted models (HR: 0.97, 95% CI: 0.79-1.18). In fully adjusted models, Hispanic-White (HR: 0.87, 95% CI: 0.73-1.03) and Asian/other-White (HR: 0.85, 95% CI: 0.63-1.15) differences in survival were not statistically significant, although patients in high-SES neighborhoods had lower mortality (HR: 0.69, 95% CI: 0.48-0.99).

CONCLUSIONS

In a multicenter cohort of patients with HCC, racial and ethnic differences in HCC prognosis were explained in part by differences in tumor stage at diagnosis and neighborhood SES. These data inform targets to intervene and reduce disparities.

Impact of social determinants of health on hepatocellular carcinoma surveillance, treatment, and health care costs

BACKGROUND

The impact of clinical factors and social determinants of health on treatment patterns and health care costs among patients with HCC is unknown.

METHODS

Using 100% Medicare Fee-For-Service claims and a commercial multipayor claims database, we identified patients diagnosed with HCC from January 1, 2017, to December 31, 2020. Surveillance receipt was defined 12 months prior to HCC diagnosis, whereas treatment and health care costs were assessed post-HCC diagnosis. Multinomial logistic regression was used to assess the association between demographics, social determinants of health, and surveillance or HCC treatment. Multivariable generalized linear regression was used to identify factors associated with total health care costs.

RESULTS

Of the 32,239 patients with HCC (mean age 68 y, 67% male, 73% White), 70% received surveillance and only half (51%) received any treatment. Curative treatment receipt was higher among those with prior surveillance (24% with CT/MRI and 18% with ultrasound vs. 9% with no surveillance). Curative treatment was independently associated with HCC surveillance and inversely associated with Black race, lower education level, and diagnosis in the year 2020 (COVID-19 year). Higher health care costs were independently associated with Black race, low English proficiency, living alone, and diagnosis in 2018-2020, and inversely associated with CT/MRI-based surveillance.

CONCLUSIONS

Race and social determinants of health were independently associated with curative treatment receipt and health care costs. Increasing access to high-quality HCC surveillance may improve treatment receipt and reduce health disparities among patients with HCC.

National Liver Cancer Screening Trial (TRACER) study protocol

BACKGROUND

Professional guidelines recommend HCC screening in at-risk patients using semi-annual ultrasound with or without alpha-fetoprotein (AFP); however, this strategy has limited effectiveness due to low adherence and sensitivity. Increasing data support the potential role of blood-based biomarker panels, which could improve both aspects. The biomarker panel GALAD, comprised of sex, age, and 3 blood biomarkers (AFP, AFP-L3, and des-carboxy prothrombin des-carboxy prothrombin), has shown high sensitivity and specificity in biomarker phase II (case-control) and phase III (retrospective cohort) validation studies. However, prospective validation in a large phase IV biomarker clinical utility trial is necessary before its adoption in practice.

METHODS

The National Liver Cancer Screening Trial is an adaptive pragmatic randomized phase IV trial, which began enrollment in January 2024, comparing ultrasound-based versus biomarker-based screening in 5500 patients with chronic hepatitis B infection or cirrhosis from any etiology. Eligible patients are randomly assigned in a 1:1 ratio to semi-annual screening with ultrasound ± alpha-fetoprotein (arm A) or semi-annual screening with GALAD (arm B). Randomization is stratified by enrollment site, liver disease severity (per Child-Pugh class), liver disease etiology (viral, nonviral, and noncirrhotic HBV), and sex. Patients are being recruited from 15 sites (a mix of tertiary care academic referral centers, safety-net health systems, and large community health systems) over a 3-year period, and the primary endpoint, reduction in late-stage HCC, will be assessed at the end of year 5.5.

DISCUSSION

The results of this trial will inform the best strategy for HCC screening and early-stage detection in patients with chronic liver diseases. If GALAD shows superiority, HCC screening would primarily shift from an ultrasound-based strategy to the adoption of the biomarker panel.

Imaging of Cirrhosis and Hepatocellular Carcinoma: Current Evidence

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Early detection of HCC is a key factor in enabling curative therapies and improving overall survival. Worldwide, several guidelines are available for surveillance of at-risk populations and diagnosis of HCC. This article provides a current comprehensive update on screening and diagnosis of HCC.

Natural History of Indeterminate Liver Nodules in Patients With Advanced Liver Disease: A Multicenter Retrospective Cohort Study

INTRODUCTION

Indeterminate liver nodules (ILNs) are frequently encountered on diagnostic imaging after positive hepatocellular carcinoma (HCC) surveillance results, but their natural history remains unclear.

METHODS

We conducted a multicenter retrospective cohort study among patients with ≥1 newly detected LI-RADS 3 (LR-3) lesion ≥1 cm or LI-RADS 4 (LR-4) lesion of any size (per LI-RADS v2018) between January 2018 and December 2019. Patients were followed with repeat imaging at each site per institutional standard of care. Multivariable Fine-Gray models were used to evaluate associations between potential risk factors and patient-level time-to-HCC diagnosis, with death and liver transplantation as competing risks.

RESULTS

Of 307 patients with ILNs, 208 had LR-3 lesions, 83 had LR-4 lesions, and 16 had both LR-3 and LR-4 lesions. HCC incidence rates for patients with LR-3 and LR-4 lesions were 110 (95% CI 70-150) and 420 (95% CI 310-560) per 1,000 person-year, respectively. In multivariable analysis, incident HCC among patients with LR-3 lesions was associated with older age, thrombocytopenia (platelet count ≤150 ×10 9 /L), and elevated serum alpha-fetoprotein levels. Among those with LR-4 lesions, incident HCC was associated with a maximum lesion diameter >1 cm. Although most patients had follow-up computed tomography or magnetic resonance imaging, 13.7% had no follow-up imaging and another 14.3% had follow-up ultrasound only.

DISCUSSION

ILNs have a high but variable risk of HCC, with 4-fold higher risk in patients with LR-4 lesions than those with LR-3 lesions, highlighting a need for accurate risk stratification tools and close follow-up in this population.

Utility of pelvic CT in patients undergoing surveillance for hepatocellular carcinoma: A retrospective multi-institutional study

OBJECTIVE

To determine the frequency, characteristics and clinical significance of incidental pelvic findings reported on abdominopelvic CT performed for hepatocellular carcinoma (HCC) surveillance in at-risk patients.

MATERIAL AND METHODS

This two-center retrospective study received institutional review board approval with a waiver of informed consent. The radiologic reports of the CT exams performed 1/1/2010-2/28/2023 for HCC surveillance were reviewed. Exams were obtained with intravenous contrast material and included hepatic arterial and portal venous phases of the abdomen; images of the pelvis were acquired during the portal venous phase. Reported imaging findings and imaging-related recommendations either by the radiologists or the corresponding caregiver, if present, were retrospectively tabulated. The patient's medical records were reviewed to determine if there were any recommendations that were considered clinically important and culminated in any further interventions or treatments.

RESULTS

259 adults (1st center: mean age, 60 ± 11 years, 49% male and 2nd center: 56.26 ± 6.2 years, 48% male) at risk for HCC underwent 327 abdominopelvic CT exams for HCC surveillance at two centers. A total of 622 pelvic findings (mean, 2.2/ exam) were reported, including 131 bladder, 120 alimentary tract, 133 vascular, 51 gynecologic, 37 prostate, 33 lymph node, 27 inguinal, 44 peritoneal, and 46 skeletal. 52 of 622 reported findings (8.3%) were associated with actionable recommendations. 24 of the 52 actionable recommendations/clinical suggestions were implemented as follows: five complimentary imaging, ten additional laboratory tests, and nine non-imaging recommendations. Of note, only eight applied recommendations culminated in a clinical outcome, which included four urinary tract infection treatments.

CONCLUSION

Pelvic CT findings were associated with a clinical benefit to the patient in 1.3% of exams. These results suggest that pelvic imaging should be omitted from CT-based HCC surveillance.

CLINICAL RELEVANCE

Without compromising valuable information, patients undergoing HCC surveillance-CT may not require additional pelvic coverage.

Risk of Hepatocellular Carcinoma in Subcentimeter Liver Nodules Identified on Surveillance Ultrasound: A Systematic Review

BACKGROUND & AIMS

Guidelines recommend that sub-centimeter nodules on ultrasound be followed with short-interval surveillance ultrasound, given assumed low risk of hepatocellular carcinoma (HCC) and suboptimal diagnostic imaging performance in lesions <1 cm. We performed a systematic review to estimate HCC risk among patients with cirrhosis and sub-centimeter nodules detected on ultrasound.

METHODS

We systematically searched Ovid MEDLINE and EMBASE databases for relevant articles published between January 2005 and July 2024. A random-effects model was used to calculate the pooled proportion of incident HCC.

RESULTS

We identified 9 eligible studies, of which 5 provided both lesion- and patient-level data (n = 354 patients), 2 patient-level alone (n = 888 patients), and 2 lesion-level alone (n = 69 lesions). The pooled proportion of incident HCC was 31.9% (95% confidence interval [CI], 8.7%-69.7%) on a lesion-level and 21.3% (95% CI, 6.0%-53.6%) on a patient-level; however, pooled estimates were limited by high heterogeneity (I2 >90%). Among 2 studies with study periods post-dating 2015, HCC developed in only ∼5% of patients during a median follow-up of 2 years. Risk factors associated with incident HCC were older age, male sex, elevated alpha-fetoprotein levels, thrombocytopenia, and Child Pugh B cirrhosis. Limitations of studies included small sample sizes, selection bias, ascertainment bias for HCC, and failure to report factors associated with HCC.

CONCLUSION

Up to one-fifth of patients with sub-centimeter nodules may develop HCC, although contemporary cohorts report a substantially lower risk. Older patients and those with elevated alpha-fetoprotein levels or poorer liver function are at greatest risk of HCC, highlighting an unmet need for better risk stratification models.

Results of hepatocellular carcinoma downstaging through hepatic transarterial chemoembolization in liver transplantation

INTRODUCTION AND AIM

Liver transplantation plays an important role in treating hepatocellular carcinoma (HCC). However, diagnosis often occurs when the tumor size exceeds Milan criteria. In this context, locoregional treatments are frequently indicated. The aim of this study is to evaluate cirrhotic patients with HCC undergoing transarterial chemoembolization (TACE) for downstaging.

METHODS

This retrospective study assessed medical records of patients aged 18 years or older, diagnosed with HCC, who underwent TACE with the aim of downstaging. In the survival analysis, the Kaplan-Meier method was used. P-value <0.05 was considered statistically significant.

RESULTS

One hundred and twenty-three patients were evaluated, of which 44.7% underwent liver transplantation after downstaging. Mortality in these patients was 32.7% and the probability of survival at 1, 2, and 5 years after liver transplantation was, respectively, 80%, 70.8%, and 57%. When comparing with the unsuccessful group, there was a significant difference regarding number of nodules, size of the largest nodule, and response by Modified Response Evaluation Criteria in Solid Tumor. The characteristics of the group undergoing TACE for downstaging and the group undergoing TACE as a bridge to transplantation were also compared, and patients were selected through the propensity score. A more significant number of nodules was observed in patients who underwent downstaging (P = 0.014) and they exceeded Milan criteria in the explanted liver more frequently (P = 0.007). Survival in the downstaging group and in the bridge group was not different (P = 0.342).

CONCLUSION

Liver transplantation in patients with HCC after successful downstaging proved to be effective, as patients had adequate survival.

Novel Biomarkers for Early Detection of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality globally. Most patients present with late diagnosis, leading to poor prognosis. This narrative review explores novel biomarkers for early HCC detection. We conducted a comprehensive literature review analyzing protein, circulating nucleic acid, metabolite, and quantitative proteomics-based biomarkers, evaluating the advantages and limitations of each approach. While established markers like alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin, and AFP-L3 remain relevant, promising candidates include circulating tumor DNA, microRNAs, long noncoding RNAs, extracellular vesicle, and metabolomic biomarkers. Multi-biomarker panels like the GALAD score, Oncoguard, and Helio liver test show promise for improved diagnostic accuracy. Non-invasive approaches like urine and gut microbiome analysis are also emerging possibilities. Integrating these novel biomarkers with current screening protocols holds significant potential for earlier HCC detection and improved patient outcomes. Future research should explore multi-biomarker panels, omics technologies, and artificial intelligence to further enhance early HCC diagnosis and management.

Blood Magnesium Level and Risk of Hepatocellular Carcinoma in a Prospective Liver Cirrhosis Cohort

BACKGROUND

Higher magnesium intake was linked to a lower risk of hepatocellular carcinoma (HCC). However, the relationship between blood magnesium level and HCC has not been fully characterized, especially among patients with liver cirrhosis who are at a higher risk for HCC.

METHODS

In the Mass General Brigham Biobank, we developed a new prospective cohort of 1,430 patients with liver cirrhosis without liver cancer history using the validated International Classification of Diseases codes. We used Cox proportional hazards models to generate hazard ratios (HRs) with 95% confidence intervals (CI) for incident HCC and used generalized estimating equations to compare changes in liver biomarkers according to baseline blood magnesium, adjusting for age, sex, race, lifestyles, body mass index, type 2 diabetes, model for end-stage liver disease score, and hepatitis infection.

RESULTS

During a median follow-up period of 4.26 years, 109 patients developed HCC. Magnesium deficiency (<1.70 mg/dL; N = 158) was associated with a higher risk of HCC (HR = 1.93; 95% CI, 1.12-3.30) compared with magnesium sufficiency (≥1.70 mg/dL; N = 1282). This association remained robust in the 1-year lag analysis (HR = 2.18; 95% CI, 1.11-4.28) and in sensitivity analysis excluding patients with alcoholic liver disease (HR = 2.41; 95% CI, 1.23-4.74). Magnesium in the lowest quartile was associated with a faster increase in alanine transaminase (β = 4.35; 95% CI, 1.06-7.63), aspartate aminotransferase (β = 6.46; 95% CI, 0.28-12.6), direct bilirubin (β = 0.18; 95% CI, 0.01-0.35), and total bilirubin (β = 0.21; 95% CI, 0.03-0.39), compared with the highest quartile.

CONCLUSIONS

Lower blood magnesium level is associated with higher HCC risk and unfavorable liver biomarker changes.

IMPACT

If confirmed, our findings may potentially enable better identification of high-risk patients for HCC and inform better management strategies for liver cirrhosis.

Adjusting to living with chronic liver disease among patients who continue regular healthcare visits for hepatocellular carcinoma surveillance: A grounded theory study

AIM

To explore patients' process of living with chronic liver disease while continuing regular healthcare visits for hepatocellular carcinoma surveillance.

METHODS

Semistructured interviews and participant observations were conducted in this qualitative constructivist grounded theory study. The participants included 11 patients undergoing regular hepatocellular carcinoma surveillance every 1-6 months for 2-30 years. Data were analyzed using coding, memo-writing, theoretical sampling, and constant comparison.

RESULTS

The participants incorporated regular healthcare visits into their living cycle. The cycle's core comprised two categories ("inferring my liver condition" and "desiring status quo"). The cycle underwent a transition described by three phases ("seeking ways to live with my chronic liver disease," "being overwhelmed by living with my chronic liver disease," and "reconstructing my life to live with my chronic liver disease"). This transition involved adjusting to living with chronic liver disease while continuing regular healthcare visits. The relative importance of the cycle's core progressively shifted from "inferring my liver condition" to "desiring status quo."

CONCLUSIONS

This study revealed the transition phases of patients' living cycles in adjusting to living with chronic liver disease while continuing regular healthcare visits. Understanding the different phases in which patients are and the psychological impact of healthcare visits can help them look forward to recuperative actions. Furthermore, patients who have a sense of ownership experience loneliness because of regular healthcare visits. A support system including nurses as part of regular hepatocellular carcinoma surveillance should be established to help ease patients' sense of loneliness by utilizing their sense of ownership.

mhealth-based interventions to improving liver cancer screening among high-risk populations: a study protocol for a randomized controlled trial

BACKGROUND

Liver cancer (LC) screening, such as AFP test and abdominal ultrasound, is an effective way to prevent LC, one of the most common cancers worldwide. Despite the proven screening benefits, screening participation among high-risk populations for LC remains low. This suggests that targeted, systematic, and effective interventions should be provided to improve knowledge and awareness related to LC screening, enhance screening intentions, and thereby promote screening behaviors. Telephone is people's main medium of daily communication and mHealth-based programs offer a potential and effective solution for promoting health behaviors. The purpose of this study is to develop and implement a mHealth (WeChat app) based intervention guided by Fogg's Behavior Model (FBM) to augment the knowledge of LC prevention among people at risk of LC and enhance their motivation for screening, and to validate its effectiveness in improving LC screening.

METHODS

We propose a two-arm, single-blind randomized controlled trial with 82 at-risk individuals of LC, delivering a 6-month mHealth-based intervention program with optional health counseling. Recruitment will be through tertiary hospitals and community organizations in 4 districts in Heng Yang. In total, 82 individuals at high risk for HCC will be randomized 1:1 to intervention or control (usual care) groups. The intervention group will receive intervention, whose contents are based on the FBM model, via multiple forms of media including PowerPoint presentation, multimedia video, health information booklet and screening message, which is delivered in the WeChat Applet. Control dyads will be provided with usual health education. Outcomes will be assessed at baseline and post-intervention.

DISCUSSION

The findings of this study will provide evidence of the benefits of utilizing mHealth-based approaches in intervention development to enhance the effectiveness of screening adherence for high-risk people of LC. Further, the findings would provide reference to the potential incorporation of the targeted intervention in local community organizations.

Cost-effectiveness of a precision hepatocellular carcinoma surveillance strategy in patients with cirrhosis

Background

Hepatocellular carcinoma (HCC) surveillance is currently performed using a one-size-fits-all strategy with ultrasound plus AFP (US + AFP). There is increasing interest in risk-stratified and precision surveillance strategies incorporating individual risk and variance in surveillance test performance; however, the cost-effectiveness of these approaches has not been evaluated.

Methods

We conducted a cost-effectiveness analysis to evaluate four surveillance strategies (no surveillance, universal US + AFP surveillance, risk-stratified surveillance, and precision surveillance) in a simulated cohort of 50-year-old patients with compensated cirrhosis. The most cost-effective strategy was that with the highest incremental cost-effectiveness ratio (ICER) and below the willingness-to-pay (WTP) threshold of $150,000/QALY gained. Model inputs were based on literature review, and costs were derived from the Medicare fee schedule.

Findings

The precision surveillance strategy demonstrated variation in recommended surveillance test based on HCC risk category and patient factors. US + AFP, risk-stratified, and precision surveillance detected more HCC cases per 100,000 population than no surveillance, with a higher proportion of early-stage cases for precision surveillance (67.6%) than risk-stratified (63.8%), universal ultrasound (63.2%), and no surveillance (38.0%). Compared to no surveillance, precision surveillance was most cost-effective, with an ICER of $104,614/QALY gained, whereas US + AFP and risk-stratified surveillance were both dominated. Compared to US + AFP, risk-stratified surveillance was cost saving and dominated US + AFP, whereas precision surveillance was cost-effective, with an ICER of $98,103/QALY gained. Results were sensitive to survival with early-stage HCC, cost of early-stage HCC treatment, and surveillance utilization. Precision surveillance remained the most cost-effective when WTP thresholds exceeded $110,000/QALY gained.

Interpretation

A precision surveillance strategy is the most cost-effective method for HCC surveillance. This approach could maximize surveillance benefits in high-risk patients, while minimizing surveillance harms in low-risk individuals.

Anabolic deficits and divergent unfolded protein response underlie skeletal and cardiac muscle growth impairments in the Yoshida hepatoma tumor model of cancer cachexia

Cancer cachexia manifests as whole body wasting, however, the precise mechanisms governing the alterations in skeletal muscle and cardiac anabolism have yet to be fully elucidated. In this study, we explored changes in anabolic processes in both skeletal and cardiac muscles in the Yoshida AH-130 ascites hepatoma model of cancer cachexia. AH-130 tumor-bearing rats experienced significant losses in body weight, skeletal muscle, and heart mass. Skeletal and cardiac muscle loss was associated with decreased ribosomal (r)RNA, and hypophosphorylation of the eukaryotic factor 4E binding protein 1. Endoplasmic reticulum stress was evident by higher activating transcription factor mRNA in skeletal muscle and growth arrest and DNA damage-inducible protein (GADD)34 mRNA in both skeletal and cardiac muscles. Tumors provoked an increase in tissue expression of interferon-γ in the heart, while an increase in interleukin-1β mRNA was apparent in both skeletal and cardiac muscles. We conclude that compromised skeletal muscle and heart mass in the Yoshida AH-130 ascites hepatoma model involves a marked reduction translational capacity and efficiency. Furthermore, our observations suggest that endoplasmic reticulum stress and tissue production of pro-inflammatory factors may play a role in the development of skeletal and cardiac muscle wasting.

EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD)

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed non-alcoholic fatty liver disease (NAFLD), is defined as steatotic liver disease (SLD) in the presence of one or more cardiometabolic risk factor(s) and the absence of harmful alcohol intake. The spectrum of MASLD includes steatosis, metabolic dysfunction-associated steatohepatitis (MASH, previously NASH), fibrosis, cirrhosis and MASH-related hepatocellular carcinoma (HCC). This joint EASL-EASD-EASO guideline provides an update on definitions, prevention, screening, diagnosis and treatment for MASLD. Case-finding strategies for MASLD with liver fibrosis, using non-invasive tests, should be applied in individuals with cardiometabolic risk factors, abnormal liver enzymes, and/or radiological signs of hepatic steatosis, particularly in the presence of type 2 diabetes (T2D) or obesity with additional metabolic risk factor(s). A stepwise approach using blood-based scores (such as FIB-4) and, sequentially, imaging techniques (such as transient elastography) is suitable to rule-out/in advanced fibrosis, which is predictive of liver-related outcomes. In adults with MASLD, lifestyle modification - including weight loss, dietary changes, physical exercise and discouraging alcohol consumption - as well as optimal management of comorbidities - including use of incretin-based therapies (e.g. semaglutide, tirzepatide) for T2D or obesity, if indicated - is advised. Bariatric surgery is also an option in individuals with MASLD and obesity. If locally approved and dependent on the label, adults with non-cirrhotic MASH and significant liver fibrosis (stage ≥2) should be considered for a MASH-targeted treatment with resmetirom, which demonstrated histological effectiveness on steatohepatitis and fibrosis with an acceptable safety and tolerability profile. No MASH-targeted pharmacotherapy can currently be recommended for the cirrhotic stage. Management of MASH-related cirrhosis includes adaptations of metabolic drugs, nutritional counselling, surveillance for portal hypertension and HCC, as well as liver transplantation in decompensated cirrhosis.

Analysis of Serum Exosome Metabolites Identifies Potential Biomarkers for Human Hepatocellular Carcinoma

Currently, the clinical cure rate for primary liver cancer remains low. Effective screening and early diagnosis of hepatocellular carcinoma (HCC) remain clinical challenges. Exosomes are intimately associated with tumor development and their contents have the potential to serve as highly sensitive tumor-specific markers. A comprehensive untargeted metabolomics study was conducted using exosome samples extracted from the serum of 48 subjects (36 HCC patients and 12 healthy controls) via a commercial kit. An ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) strategy was used to identify the metabolic compounds. A total of 18 differential metabolites were identified using the non-targeted metabolomics approach of UPLC-QTOF-MS/MS. Pathway analysis revealed significant alterations in the arachidonic acid metabolism, linoleic acid metabolism, and unsaturated fatty acid metabolism pathways. ROC analysis indicated that three metabolites with AUC values exceeding 0.900 were selected as potential biomarkers: caprylic acid and linoleic acid were upregulated in the HCC group, whereas pentadecanoic acid was downregulated. Linoleic acid, caprylic acid, and pentadecanoic acid are potential biomarkers for diagnosing HCC. The significant alterations in these three metabolic pathways offer new insights into the mechanisms underlying HCC formation and progression.

Associations of tumor-related psychiatric symptoms and healthy behaviors with dynamic quality of life after hepatocellular carcinoma hepatectomy

OBJECTIVE

To assess the independent and combined associations of tumor-related psychiatric symptoms (TRPS) with dynamic health-related quality of life (HRQL) in patients with hepatocellular carcinoma (HCC) after hepatectomy and to identify related patterns of health behaviors.

METHODS

This prospective study included patients with HCC who underwent hepatectomy between September 2021 and May 2022. Independent and combined associations between TRPS and HRQL were identified by generalized linear model and weighted quantile sum model, respectively. Trajectories of HRQL were identified by latent class mixed model.

RESULTS

Among the 205 patients, 174 (84.9%) were male. For the outcome of HRQL at 6 months: Anxiety, depression, fatigue, and sleep disorder were independently associated with a decrease of HRQL (all P < 0.05). A negative combined effect of TRPS was also found (β =  - 5.07, 95% CI, - 10.01 to - 0.13), with depression emerged as the predominant contributor (49%). The health behaviors of body mass index, smoking, drinking, or physical exercise were not significantly modified the associations between combined TRPS and HRQL (all P > 0.05 for interaction). Similar results were also found for the HRQL at baseline and at 1 and 3 months. Three HRQL trajectory groups were identified: recover (44.9%), poor (44.4%), and deteriorating (10.7%). Deteriorating group was associated with higher incidence of TRPS (all P < 0.05).

CONCLUSIONS

TRPS were associated with a decrease of HRQL regardless of healthy behaviors in HCC patients. Therefore, healthy behaviors promotion alone might not substantially increase HRQL associated with TRPS, and other measures tackling TRPS are warranted.

Cost-Effectiveness of Hepatocellular Carcinoma Surveillance Strategies in Patients With Compensated Liver Cirrhosis in the United Kingdom

OBJECTIVES

This study aimed to evaluate the cost-effectiveness (CE) of 4 hepatocellular carcinoma (HCC) surveillance strategies in the United Kingdom, the GAAD algorithm, which combines Gender (biological sex) and Age with Elecsys® biomarker assays, alpha-fetoprotein (AFP) and protein induced by vitamin K absence-II (previously Des-γ-carboxy prothrombin); ultrasound (US); US + AFP and GAAD + US.

METHODS

A de novo microsimulation state-transition Markov model was developed in Microsoft Excel® from the perspective of the United Kingdom National Health Service to calculate life-years, quality-adjusted life-years (QALYs), costs, incremental CE ratios, and net monetary benefits. Parameters were sourced from peer-reviewed published literature, national guidelines, and public cost databases. Sensitivity and scenario analyses were performed to evaluate the impact of parameter and structural uncertainty on the results.

RESULTS

In a simulated cohort of 100 000 patients, discounted costs and QALYs per patient were £8663 and 6·066 for US, £9095 and 6·076 for US + AFP, £8719 and 6·078 for GAAD alone, and £9114 and 6·086 for GAAD + US. At a CE threshold of £20 000/QALY, GAAD was the most cost-effective strategy; however, although most costly, GAAD + US was the most clinically effective. Sensitivity and scenario analyses indicated that HCC incidence along with costs associated with diagnostic performance influence CE.

CONCLUSION

Considering the cost of US and low incidence of HCC in the United Kingdom, this study suggests that GAAD alone or in combination with US are cost-effective surveillance strategies compared with US and US + AFP. Although GAAD + US showed the highest QALY increase, GAAD alone is considered preferable regarding CE; however, better performance estimates for GAAD + US are needed to confirm.

Psychiatric disorders in patients with hepatocellular carcinoma: A large US cohort of commercially insured individuals

BACKGROUND/AIMS

Patients with hepatocellular cancer (HCC) are vulnerable to psychological distress given a new cancer diagnosis superimposed on pre-existing chronic liver disease. We aimed to characterise the psychiatric burden in HCC, risk factors for incident diagnosis and treatment patterns over time.

METHODS

Using IQVIA PharMetrics® Plus for Academics-a nationally representative claims database of the commercially insured US population-we identified psychiatric diagnoses and treatment among patients with newly diagnosed HCC. Multivariable logistic regression modelling identified factors associated with psychiatric diagnosis and treatment.

RESULTS

Of 11,609 patients with HCC, 2166 (18.6%) had a psychiatric diagnosis after cancer diagnosis with depression (58.3%) and anxiety (53.0%) being most common. Women (aOR 1.33, 95% CI [1.19-1.49]), pre-existing psychiatric diagnoses (aOR 9.12 [8.08-10.3]) and HCC treatment type (transplant: aOR 2.15 [1.66-2.77]; locoregional therapies: aOR 1.74 [1.52-1.99]; hospice: aOR 2.43 [1.79-3.29]) were significantly associated with psychiatric diagnosis. Female sex, ascites, higher comorbidity and treatment type were associated with incident psychiatric diagnosis. Pharmacotherapy was used in 1392 (64.3%) patients with a psychiatric diagnosis, with antidepressants (46.2%) and anxiolytics (32.8%) being most common. Psychiatric diagnoses increased from 14.8% in 2006-2009 to 21.1% in 2018-2021 (p < 0.001). In almost 20% of patients with pre-existing psychiatric conditions, therapy was discontinued after HCC diagnosis.

CONCLUSIONS

Nearly 2 of 10 patients with HCC were diagnosed with a psychiatric condition after cancer diagnosis with unique sociodemographic and clinical risk factors identified. This highlights a risk for increased psychological burden in need of early evaluation and treatment among patients with newly diagnosed HCC.

Implementation of a Hepatocellular Carcinoma Surveillance Program in a Community-Based Integrated Health System in Patients With Hepatitis C Cirrhosis

INTRODUCTION

Underutilization of hepatocellular cancer (HCC) surveillance has been reported, although data evaluating interventions to improve surveillance are sparse. We assessed the effect of a population-based HCC surveillance program on HCC surveillance utilization and outcomes.

METHODS

In this retrospective cohort study, we assessed preinclusion and postinclusion HCC surveillance patterns among 597 patients with hepatitis C virus cirrhosis enrolled in a program at an integrated health system between 2013 and 2020. Adequate surveillance was defined as at least 5 surveillance studies within 36 months pre-enrollment and postenrollment; a secondary outcome was proportion of time covered by surveillance over 36 months. Tumor size, stage, and receipt of curative therapy were compared between HCC detected on the first imaging examination (prevalent HCC) and surveillance-detected HCC (incident HCC). We performed Kaplan-Meier analysis and multivariable competing risk analysis to characterize the association between surveillance and mortality.

RESULTS

The surveillance program significantly improved surveillance completion (77.6% vs 5.0%, P < 0.001) and proportion time covered (80.9% vs 15.8%, P < 0.001). Compared with prevalent HCC, surveillance-detected cases were more likely unifocal (77.8% vs 44.8%, P < 0.001), early-stage (85.2% vs 44.8%, P < 0.001), with smaller maximum diameter (median 2.3 vs 3.2 cm), and more likely to undergo curative therapy (92.5% vs 72.4% P = 0.010). Survival was improved compared with prevalent cases hazard ratio (HR) 0.23 (0.11-0.51) after adjusting for age and Model for End Stage Liver Disease score.

DISCUSSION

Implementation of a population-based program resulted in significant improvement in HCC surveillance use and clinical outcomes among patients with hepatitis C virus cirrhosis. These findings may inform similar interventions by other healthcare systems.
