Racial and Ethnic Differences in Presentation and Outcomes of Hepatocellular Carcinoma

Health disparities in cirrhosis care and liver transplantation

Morbidity and mortality from cirrhosis are substantial and increasing. Health disparities in cirrhosis and liver transplantation are reflective of inequities along the entire spectrum of chronic liver disease care, from screening and diagnosis to prevention and treatment of liver-related complications. The key populations experiencing disparities in health status and healthcare delivery include racial and ethnic minority groups, sexual and gender minorities, people of lower socioeconomic status and underserved rural communities. These disparities lead to delayed diagnosis of chronic liver disease and complications of cirrhosis (for example, hepatocellular carcinoma), to differences in treatment of chronic liver disease and its complications, and ultimately to unequal access to transplantation for those with end-stage liver disease. Calling out these disparities is only the first step towards implementing solutions that can improve health equity and clinical outcomes for everyone. Multi-level interventions along the care continuum for chronic liver disease are needed to mitigate these disparities and provide equitable access to care.

Care fragmentation in hepatocellular carcinoma: Opportunities to fix a broken sector

BACKGROUND

Care fragmentation refers to receipt of health care services through multiple institutions. Although care fragmentation has been linked to inferior oncologic outcomes, it also captures "upgrades" to specialized centers. Herein, we investigate the association between care fragmentation and hepatocellular carcinoma survival in California.

STUDY DESIGN

Hepatocellular carcinoma cases occurring between January 1, 2007, and December 31, 2017, were retrospectively identified through a maintained, statewide database. Care fragmentation was measured (1) as a binary classification of fragmented or nonfragmented care, (2) by the number of facilities visited, and (3) in terms of care directionality through which care fragmentation occurred between Network of Comprehensive Cancer/National Cancer Institute-designated and -nondesignated centers, within 2 years of diagnosis. Multivariable time-varying covariate Cox regression analyses were used to model the impact of care fragmentation on overall survival.

RESULTS

Of 10,825 patients with hepatocellular carcinoma, 5,778 patients (53.4%) received fragmented care. Compared with nonfragmented care, fragmented care was associated with worse overall survival (hazard ratio, 1.81; 95% confidence interval, 1.72-1.91, P < .001) by our analyses. The quantity of centers visited also corresponded to a greater mortality (2 facilities: hazard ratio, 1.65; 95% confidence interval, 1.56-1.75, P < .001; 3 facilities: hazard ratio, 2.21; 95% confidence interval, 2.02-2.41, P < .001; 4+ facilities: hazard ratio, 2.66; 95% confidence interval, 2.35-3.02, P < .001). Compared with nonfragmented-designated, all other care fragmentation directionality patterns, including fragmented-designated and nondesignated care, decreased overall survival (hazard ratio, 1.74; 95% confidence interval, 1.55-1.95, P < .001). Care fragmentation in surgical patients showed a similar trend for the fragmented-designated and nondesignated pattern (hazard ratio, 1.67; 95% confidence interval, 1.30-2.14, P < .001).

CONCLUSION

In hepatocellular carcinoma, fragmented care is associated with worse survival. Although fragmented-designated and nondesignated care was expected to mitigate such effect, this was not observed. Additional mechanisms driving such findings warrant further investigation.

County-Level Food Insecurity and Hepatocellular Carcinoma Risk: A Cross-Sectional Analysis

Food insecurity (FI) is associated with several known hepatocellular carcinoma (HCC) risk factors, but few studies have directly examined FI in association with HCC risk. We aimed to investigate whether county-level FI is associated with HCC risk. We used data from 21 registries in the Surveillance Epidemiology and End Results database to obtain county-level counts of HCC cases from 2018 to 2021. We obtained the county-level FI rates for 2018-2021 from Feeding America's Map the Meal Gap. We used multi-level Poisson regression models with robust standard errors to calculate incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Overall, a one-standard-deviation (SD) increase in county-level FI was associated with an 8% increase in HCC risk in the fully adjusted model (IRR = 1.08, 95% CI = 1.06, 1.10). When stratified by age at diagnosis, a one-SD increase in county-level FI was associated with a 2% higher risk of HCC in the ≥65 age group (IRR = 1.02, 95% CI = 1.00, 1.05) and a 15% higher risk in the <65 age group (IRR = 1.15, 95% CI = 1.11, 1.19; interaction p-value < 0.001). If confirmed in other studies, these findings support the need for interventions and policies addressing FI in populations at increased risk for HCC.

Racial Disparities in Liver Transplant for Hepatitis C-Associated Hepatocellular Carcinoma

BACKGROUND

In the United States, hepatitis C virus-associated hepatocellular carcinoma incidence and mortality are highest among minorities. Socioeconomic constraints play a major role in inequitable treatment. We evaluated the association between race/ethnicity and outcomes in a population that overcame treatment barriers.

METHODS

We report a retrospective cohort study of 666 patients across 20 institutions in the United States Hepatocellular Carcinoma Liver Transplantation Consortium from 2015 to 2019 with hepatitis C virus-associated hepatocellular carcinoma who completed direct-acting antiviral therapy and underwent liver transplantation. Patients were excluded if they had a prior liver transplantation, hepatocellular carcinoma recurrence, no prior liver-directed therapy, or if race/ethnicity data were unavailable. Patients were stratified by race/ethnicity. Primary outcomes were recurrence-free survival and overall survival, and secondary outcome was major postoperative complication.

RESULTS

Race/ethnicity was not associated with differences in 5-year recurrence-free survival (White 90%, Black 88%, Hispanic 92%, Other 87%; p = 0.85), overall survival (White 85%, Black 84%, Hispanic 84%, Other 93%; p = 0.70), or major postoperative complication.

CONCLUSIONS

Race/ethnicity was not associated with worse oncologic or postoperative outcomes among those who completed direct-acting antiviral therapy and underwent liver transplantation, suggesting that overcoming socioeconomic constraints equalizes outcomes across racial/ethnic groups. Eliminating barriers that prohibit care access among minorities must be a priority.

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.

Atezolizumab plus bevacizumab as first-line systemic therapy for hepatocellular carcinoma: a multi-institutional cohort study

BACKGROUND

Atezolizumab plus bevacizumab is the standard of care for advanced hepatocellular carcinoma (HCC) in the first-line setting, although was only evaluated in patients with Child-Pugh (CP) A liver function in the IMbrave150 trial. We sought to determine the outcomes of these patients based on CP score and ALBI grade in the US population.

METHODS

This multicenter cohort study included patients with HCC who received atezolizumab with bevacizumab as first-line systemic therapy between March 2018 and November 2023. Overall survival (OS) was determined using the Kaplan-Meier method and multivariate analyses were performed using Cox proportional hazard regression method.

RESULTS

Among 322 patients, 226, 86, and 10 patients had CP-A, CP-B, and CP-C liver function, respectively. Median age was 66.5 years, 78.6% were male, and 82.6% were White. Median OS (mOS) was 21.6 months for those with CP-A, 9.1 months for those with CP-B7, and 4.7 months for those with CP-B8-C12 (P < .0001). Among patients with CP-A, those with ALBI grade 1 had an mOS of 34.9 months versus 14.2 months in those with grade 2. In multivariate analyses, CP score, ALBI grade, hepatitis B, performance status, and macrovascular invasion were significantly associated with survival.

CONCLUSIONS

CP score is an important prognostic tool for patients with HCC receiving atezolizumab plus bevacizumab, and this regimen remains a viable option for patients with CP-B7 with no additional safety concern, although the benefit is significantly less than those with CP-A. ALBI score has independent predictive value in patients with CP-A liver function.

Trends in Hepatocellular Carcinoma Mortality Rates in the US and Projections Through 2040

Importance

The burden of liver cancer varies worldwide. An upward trend in both hepatocellular carcinoma (HCC) incidence and mortality in the past 2 decades has been observed.

Objective

To assess observed HCC-related age-standardized mortality rates (ASMRs) in the US for 2006 to 2022 and provide ASMR projections through 2040.

Design, Setting, and Participants

This cross-sectional study used data from the National Vital Statistics System, which is accessible through the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research website. Data on deaths attributed to HCC (from January 1, 2006, to December 31, 2022) were obtained for adults 25 years or older and were stratified by liver disease etiology, age, sex, and race and ethnicity. Etiologies included alcohol-associated liver disease (ALD), hepatitis B virus (HBV), hepatitis C virus (HCV), and metabolic dysfunction-associated steatotic liver disease (MASLD).

Main Outcomes and Measures

The main outcomes were (1) observed ASMRs of HCC per 100 000 persons using Joinpoint regression (National Cancer Institute) to assess trends during 2006 to 2022 and (2) ASMRs projected for 2023 to 2040 using Prophet and AutoARIMA modeling.

Results

This study included 188 280 HCC-related deaths from 2006 to 2022. Most deaths occurred among males (77.4%). The annual percentage change was 4.1% (95% CI, 2.2% to 7.7%) for 2006 to 2009 and decreased to 1.8% (95% CI, 0.7% to 2.0%) for 2009 to 2022, with an overall observed ASMR of 5.03 per 100 000 persons in 2022 and a projected ASMR of 6.39 per 100 000 persons by 2040, with consistent trends for both sexes. By etiology, ASMRs decreased for HCV- and HBV-related mortality but increased for ALD- and MASLD-related mortality. In 2022, MASLD surpassed HBV as the third-leading cause of HCC-related death and was projected to overtake HCV in 2032 as the second-leading cause; ALD was projected to be the leading cause of HCC-related death in 2026. In 2022, the ASMR was higher among individuals aged 65 years or older compared with those aged 25 to 64 years (18.37 vs 1.79 per 100 000 persons). The American Indian or Alaska Native population had the largest increase in projected ASMR by 2040 (14.71 per 100 000 persons) compared with the Asian population (3.03 per 100 000 persons).

Conclusions and Relevance

In this cross-sectional study, ASMRs for ALD- and MASLD-related HCC death increased rapidly from 2006 to 2022; ALD-related HCC was projected to be the leading cause by 2026, with MASLD as the second-leading cause by 2032. These findings may serve as a reference for public health decision-making and timely identification of groups at high risk of HCC death.

The impact of congenital heart disease on treatment and survival of patients with hepatoblastoma: A single-center experience

BACKGROUND

Patients with hepatoblastoma (HB) have a higher risk of congenital heart defects (CHD). There is limited literature on the management and outcomes of these patients. The purpose of this study was to identify demographics and outcomes of these patients in a single tertiary referral center.

METHODS

An Institutional Review Board (IRB)-approved retrospective chart review of patients with newly diagnosed HB from October 2004 to January 2021 was performed. CHD was defined as the presence of a septal defect, patent ductus arteriosus, pulmonary atresia, or bicuspid aortic valve. Chi-square and t-test were utilized for statistical analyses.

RESULTS

Of the 151 patients diagnosed with HB during the study timeframe, 29 patients were found to have CHD. Five-year overall survival (OS) for non-CHD HB patients was 81.9% compared to 68.9% in the CHD cohort (p = .12). The 5-year OS for patients without surgically intervened CHD was 63.6% compared to 70.5% for those with surgically repaired CHD (p = .88). Pre-treatment extent of tumor IV was present more often in patients with HB and CHD who passed away (6/9, 66.7%) compared to those who survived (3/16,18.8%, p = .01).

CONCLUSIONS

Patients with HB and CHD have similar survival compared to those without CHD. Our data support that patients with HB and CHD should be treated with curative intent including cardiac surgical intervention, medical oncology therapy, and oncological surgery for their HB.

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.

Overall Survival in Real-World Patients with Unresectable Hepatocellular Carcinoma Receiving Atezolizumab Plus Bevacizumab Versus Sorafenib or Lenvatinib as First-Line Therapy: Findings from the National Veterans Health Administration Database

Background/Objectives: This study evaluated comparative overall survival (OS) of United States veterans with unresectable hepatocellular carcinoma (uHCC) receiving first-line (1L) atezolizumab plus bevacizumab vs. sorafenib or lenvatinib, overall and across racial and ethnic groups. Methods: In this retrospective study, patients with uHCC who initiated atezolizumab plus bevacizumab (post-2020) or sorafenib or lenvatinib (post-2018) were identified from the Veterans Health Administration National Corporate Data Warehouse (1 January 2017-31 December 2022). Patient characteristics were evaluated in the year prior to 1L treatment initiation. Kaplan-Meier and multivariable Cox regression methods were used to compare OS starting from treatment between cohorts, both overall and by race and ethnicity. Results: Among the 1874 patients included, 405 (21.6%) received 1L atezolizumab plus bevacizumab, 1016 (54.2%) received sorafenib, and 453 (24.2%) received lenvatinib, with a median follow-up time of 8.5, 7.6, and 8.2 months, respectively. Overall, patients receiving atezolizumab plus bevacizumab had longer unadjusted median OS (12.8 [95% CI: 10.6, 17.1] months) than patients receiving sorafenib (8.0 [7.1, 8.6] months) or lenvatinib (9.5 [7.8, 11.4] months; both log-rank p < 0.001). After adjustment, atezolizumab plus bevacizumab was associated with a reduced risk of death by 30% vs. sorafenib (adjusted HR: 0.70 [95% CI: 0.60, 0.82]) and by 26% vs. lenvatinib (0.74 [0.62, 0.88]; both p < 0.001). OS trends in the White, Black, and Hispanic patient cohorts were consistent with that of the overall population. Conclusions: Atezolizumab plus bevacizumab was associated with improved survival outcomes compared with sorafenib and lenvatinib in patients with uHCC, both overall and across racial and ethnic subgroups.

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.

Survival Outcomes Among Patients With Hepatocellular Carcinoma in a Large Integrated US Health System

Importance

Hepatocellular carcinoma (HCC) is the leading oncologic cause of death among patients with cirrhosis, but large studies examining mortality trends are lacking.

Objective

To evaluate survival among patients with HCC in one of the largest integrated health care systems in the US.

Design, Setting, and Participants

This retrospective cohort study included 3441 adult patients who received a diagnosis of HCC between January 1, 2006, and December 31, 2019, with end of follow-up on December 31, 2020. The study period was further categorized as era 1, defined as 2006 to 2012, and era 2, defined as 2013 to 2019. Statistical analysis was conducted from January 2021 to June 2024.

Exposures

Patient demographic characteristics and disease factors.

Main Outcomes and Measures

All-cause and HCC-specific mortality were used as primary end points, and survival probabilities were estimated using the Kaplan-Meier method. Cox proportional hazards regression analyses were adjusted for age at diagnosis, sex, race and ethnicity, cause of disease, Barcelona Clinic Liver Cancer (BCLC) stage, alpha-fetoprotein level, and treatment type.

Results

Of 3441 patients with HCC, 2581 (75.0%) were men, and the median age was 65 years (IQR, 58-73 years). A total of 1195 patients (34.7%) received curative treatment, 1374 (39.9%) received noncurative treatment, and 872 (25.3%) received no treatment. During the study period, 2500 patients (72.7%) experienced all-cause mortality, and 1809 (52.6%) had HCC-specific mortality. In multivariable analysis, being 70 years of age or older (adjusted hazard ratio [AHR], 1.39; 95% CI, 1.22-1.59), male sex (AHR, 1.20; 95% CI, 1.07-1.35), BCLC stage C or D (AHR, 2.40; 95% CI, 2.15-2.67), increasing alpha-fetoprotein level (vs <20 ng/mL; 20-99 ng/mL: AHR, 1.20; 95% CI, 1.04-1.38; ≥1000 ng/mL: AHR, 2.84; 95% CI, 2.45-3.25), noncurative treatment (AHR, 2.51; 95% CI, 2.16-2.90), and no treatment (AHR, 3.15; 95% CI, 2.64-3.76) were associated with higher all-cause mortality, while Asian or Other Pacific Islander race and ethnicity (vs non-Hispanic White; AHR, 0.76; 95% CI, 0.65-0.88) was associated with lower all-cause mortality. Survival improved in diagnosis era 2 (2013-2019; n = 2007) compared with diagnosis era 1 (2006-2012; n = 1434).

Conclusions and Relevance

This large, racially and ethnically diverse cohort study of patients with HCC found improving survival over time, especially among individuals with early-stage HCC receiving potentially curative treatments. This study highlights the importance of surveillance for detection of HCC at early stages, particularly among groups at risk for poorer outcomes.

Disparities Associated with Decision to Undergo Oncologic Surgery: A Prospective Mixed-Methods Analysis

BACKGROUND

Underrepresented minority patients with surgical malignancies experience disparities in outcomes. The impact of provider-based factors, including communication, trust, and cultural competency, on outcomes is not well understood. This study examines modifiable provider-based barriers to care experienced by patients with surgical malignancies.

METHODS

A parallel, prospective, mixed-methods study enrolled patients with lung or gastrointestinal malignancies undergoing surgical consultation. Surveys assessed patients' social needs and patient-physician relationship. Semi-structured interviews ascertained patient experiences and were iteratively analyzed, identifying key themes.

RESULTS

The cohort included 24 patients (age 62 years; 63% White and 38% Black/African American). The most common cancers were lung (n = 18, 75%) and gastroesophageal (n = 3, 13%). Survey results indicated that food insecurity (n = 5, 21%), lack of reliable transportation (n = 4, 17%), and housing instability (n = 2, 8%) were common. Lack of trust in their physician (n = 3, 13%) and their physician's treatment recommendation (n = 3, 13%) were identified. Patients reported a lack of empathy (n = 3, 13%), lack of cultural competence (n = 3, 13%), and inadequate communication (n = 2, 8%) from physicians. Qualitative analysis identified five major themes regarding the decision to undergo surgery: communication, trust, health literacy, patient fears, and decision-making strategies. Five patients (21%) declined the recommended surgery and were more likely Black (100% vs. 21%), lower income (100% vs. 16%), and reported poor patient-physician relationship (40% vs. 5%; all p < 0.05).

CONCLUSIONS

Factors associated with declining recommended cancer surgery were underrepresented minority race and poor patient-physician relationships. Interventions are needed to improve these barriers to care and racial disparities.

Hepatocellular carcinoma and lipid metabolism: Novel targets and therapeutic strategies

Hepatocellular carcinoma (HCC) is an increasingly prevalent disease that is associated with high and continually rising mortality rates. Lipid metabolism holds a crucial role in the pathogenesis of HCC, in which abnormalities pertaining to the delicate balance of lipid synthesis, breakdown, and storage, predispose for the pathogenesis of the nonalcoholic fatty liver disease (NAFLD), a disease precursor to HCC. If caught early enough, HCC treatment may be curative. In later stages, treatment is only halting the inevitable outcome of death, boldly prompting for novel drug discovery to provide a fighting chance for this patient population. In this review, we begin by providing a summary of current local and systemic treatments against HCC. From such we discuss hepatic lipid metabolism and highlight novel targets that are ripe for anti-cancer drug discovery. Lastly, we provide a targeted summary of current known risk factors for HCC pathogenesis, providing key insights that will be essential for rationalizing future development of anti-HCC therapeutics.

Short-Term Out-of-Pocket and Total Costs of Care After Ablation, Resection, or Transplant for Early-Stage Hepatocellular Carcinoma: A National SEER-Medicare Cost Comparison

BACKGROUND. Differences in survival and morbidity among treatment options (ablation, surgical resection, and transplant) for early-stage hepatocellular carcinoma (HCC) have been well studied. Additional understanding of the costs of such care would help to identify drivers of high costs and potential barriers to care delivery. OBJECTIVE. The purpose of this article was to quantify total and patient out-of-pocket costs for ablation, surgical resection, and transplant in the management of early-stage HCC and to identify factors predictive of these costs. METHODS. This retrospective U.S. population-based study used the SEER-Medicare linked dataset to identify a sample of 1067 Medicare beneficiaries (mean age, 73 years; 674 men, 393 women) diagnosed with early-stage HCC (size ≤ 5 cm) treated with ablation (n = 623), resection (n = 201), or transplant (n = 243) between January 2009 and December 2016. Total costs and patient out-of-pocket costs for the index procedure as well as for any care within 30 and 90 days after the procedure were identified and stratified by treatment modality. Additional comparisons were performed among propensity score-matched subgroups of patients treated by ablation or resection (each n = 172). Multivariable linear regression models were used to identify factors predictive of total costs and out-of-pocket costs for index procedures as well as for 30- and 90-day post-procedure periods. RESULTS. For ablation, resection, and transplant, median index-procedure total cost was US$6689, US$25,614, and US$66,034; index-procedure out-of-pocket cost was US$1235, US$1650, and US$1317; 30-day total cost was US$9456, US$29,754, and US$69,856; 30-day out-of-pocket cost was US$1646, US$2208, and US$3198; 90-day total cost was US$14,572, US$34,984, and US$88,103; and 90-day out-of-pocket cost was US$2138, US$2462, and US$3876, respectively (all p < .001). In propensity score-matched subgroups, ablation and resection had median index-procedure, 30-day, and 90-day total costs of US$6690 and US$25,716, US$9995 and US$30,365, and US$15,851 and US$34,455, respectively. In multivariable analysis adjusting for socioeconomic factors, comorbidities, and liver-disease prognostic indicators, surgical treatment (resection or transplant) was predictive of significantly greater costs compared with ablation at all time points. CONCLUSION. Total and out-of-pocket costs for index procedures as well as for 30-day and 90-day postprocedure periods were lowest for ablation, followed by resection and then transplant. CLINICAL IMPACT. This comprehensive cost analysis could help inform future cost-effectiveness analyses.

Disparities in hepatocellular carcinoma incidence among Hispanic and non-Hispanic adults in Arizona: Trends between 2009-2017

BACKGROUND

Hepatocellular carcinoma (HCC) is a highly lethal cancer with few treatment options available to patients. Most HCC cases in Arizona, a state with a high proportion of Hispanic adults, have not been included in recent reports of HCC incidence. This study describes trends in HCC incidence and stage at diagnosis among Arizona residents between 2009-2017 and reports on racial and ethnic disparities for these outcomes.

METHODS

The Arizona Cancer Registry was used to identify Arizonans aged 19 or older diagnosed with liver cell carcinoma diagnosed between 2009-2017. A total of 5043 cases were examined. Adjusted annual and 3-year HCC incidence rates (per 100,000) were examined for non-Hispanic White (NHW) and Hispanic adults.

RESULTS

The total age-adjusted HCC incidence rate increased significantly between 2009-2012 and then declined significantly between 2012-2017. Across nearly all years, age-adjusted HCC incidence in Hispanic adults was twice that of NHW adults. Hispanic adults were more likely to be diagnosed at a later stage across all time periods. The disparity in 3-year age-adjusted HCC incidence rate between NHW and Hispanic adults decreased between 2009-2017.

CONCLUSION

Whe total age-adjusted HCC incidence rate increased significantly between 2009-2012 and then declined significantly between 2012-2017. Across nearly all years, age-adjusted HCC incidence in Hispanic adults was twice that of NHW adults. Hispanic adults were more likely to be diagnosed at a later stage across all time periods. The disparity in 3-year age-adjusted HCC incidence rate between NHW and Hispanic adults decreased between 2009-2017.

Financial burden in a US cohort of patients with HCC

BACKGROUND

High financial burden for patients has been reported for multiple types of cancer, but there are limited data in those with HCC. We aimed to describe the financial burden for patients diagnosed with HCC and identify correlates of high financial burden.

METHODS

We used the IQVIA PharMetrics Plus for Academics database to identify commercially insured patients diagnosed with HCC between 2006 and 2021. Patient financial liability was defined as the difference between allowed and paid amounts from adjudicated insurance claims. We reported total and HCC-related financial liabilities (i.e., cost for HCC-related claims), with high total financial liability defined as ≥$3000 annually and high HCC-related financial liability as ≥$1000 annually. We used multivariable logistic regression modeling to identify factors associated with high total and HCC-related financial liability.

RESULTS

Among 11,609 patients with HCC, the median total financial liability during the year after HCC diagnosis was $2955 (Q1-Q3: $972-$6293). Nearly half (45%) of patients experienced high total financial liability, with the greatest liability incurred in the 3-month period immediately following HCC diagnosis. Older age, increased comorbidity, and cirrhosis-related complications were associated with higher total patient liability. Patient liability also varied by type of HCC treatment, with systemic therapy and liver transplantation having the highest financial liability in multivariable analysis. However, only 66.7% of the patients experienced HCC-related liability.

CONCLUSIONS

Patients with HCC experience significant financial liability underscoring a need for price transparency as well as financial counseling in this population.

Racial-ethnic differences in liver transplant waitlist outcomes in patients with hepatocellular carcinoma before and after recent changes to allocation policy

BACKGROUND

In May 2019, liver transplant (LT) allocation policy changed to limit MELD exception points for hepatocellular carcinoma (HCC) to median MELD at transplant minus three (MMaT-3). We evaluated this policy's impact on waitlist outcomes for HCC candidates, by race and ethnicity, hypothesizing that the introduction of the MMaT-3 reduced inequities in waitlist outcomes.

METHODS

Retrospective cohort study of the Scientific Registry for Transplant Recipients, including all adult LT candidates (N = 10 751) who received HCC exception points from May 17, 2017 to May 18, 2019 (pre-policy; N = 6627) to May 19, 2019 to March 1, 2021 (post-policy; N = 4124). We compared incidence of LT and waitlist removal for death or becoming too sick pre- and post-policy for non-Hispanic White, non-Hispanic Black, Hispanic/Latinx, and Asian patients using competing risk regression adjusted for candidate characteristics.

RESULTS

One-year cumulative incidence of LT decreased significantly pre-/post-policy among White (77.4% vs. 64.5%; p < .01) and Black (76.2% vs. 63.1%; p < .01) candidates only, while a 1-year incidence of death/non-LT waitlist removal decreased significantly only among Hispanics (13.4% vs. 7.5%; p < .01). After covariate adjustment, the effect of the policy change was a significantly decreased incidence of LT for White (SHR: .63 compared to pre-policy; p < .001), Black (SHR: .62; p < .001), and Asian (SHR: .68; p = .002), but no change for Hispanic patients. Only Hispanic patients had a significant decrease in death/waitlist removal after the policy change (SHR:  .69; p = .04). Compared to White patients in the pre-policy era, Hispanic (SHR:  .88, p < .007) and Asian candidates (SHR:  .72; p < .001) had lower unadjusted incidence of LT. This disparity was mitigated in the post-policy era where Hispanic patients had higher likelihood of LT than Whites (SHR: 1.22; p = .002). For the outcome of death/non-LT waitlist removal, the only significant difference was a 42% lower incidence of waitlist removal for Asian compared to White patients in the post-policy era (SHR:  .58; p = .03).

CONCLUSION

Among LT recipients with HCC, racial/ethnic subpopulations were differentially affected by the MMAT-3 policy, resulting in a post-policy reduction of some of the previous disparities.

Systemic Therapy for Advanced Hepatocellular Carcinoma: ASCO Guideline Update

PURPOSE

To update an evidence-based guideline to assist in clinical decision-making for patients with advanced hepatocellular carcinoma (HCC).

METHODS

ASCO convened an Expert Panel to update the 2020 guideline on systemic therapy for HCC. The panel updated the systematic review to include randomized controlled trials (RCTs) published through October 2023 and updated recommendations.

RESULTS

Ten new RCTs met the inclusion criteria and were added to the evidence base.

RECOMMENDATIONS

Atezolizumab + bevacizumab (atezo + bev) or durvalumab + tremelimumab (durva + treme) may be offered first-line for patients with advanced HCC, Child-Pugh class A liver disease, and Eastern Cooperative Oncology Group performance status 0-1. Where there are contraindications to these therapies, sorafenib, lenvatinib, or durvalumab may be offered first-line. Following first-line treatment with atezo + bev, second-line therapy with a tyrosine kinase inhibitor (TKI), ramucirumab (for patients with alpha-fetoprotein [AFP] ≥400 ng/mL), durva + treme, or nivolumab + ipilimumab (nivo + ipi) may be recommended for appropriate candidates. Following first-line therapy with durva + treme, second-line therapy with a TKI is recommended. Following first-line treatment with sorafenib or lenvatinib, second-line therapy options include cabozantinib, regorafenib for patients who previously tolerated sorafenib, ramucirumab (AFP ≥400 ng/mL), nivo + ipi, or durvalumab; atezo + bev or durva + treme may be considered for patients who did not have access to these therapies in the first-line setting, and do not have contraindications. Pembrolizumab or nivolumab are also options for appropriate patients following sorafenib or lenvatinib. Third-line therapy may be considered in Child-Pugh class A patients with good PS, using one of the agents listed previously that has a nonidentical mechanism of action with previously received therapy. A cautious approach to systemic therapy is recommended for patients with Child-Pugh class B advanced HCC. Further guidance on choosing between options is included within the guideline.Additional information is available at www.asco.org/gastrointestinal-cancer-guidelines.

Immunotherapy as a Complement to Surgical Management of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the most common primary liver tumor in adults, and the fourth leading cause of cancer-related deaths worldwide. While surgical and ablative therapies remain the standard of care in early localized disease, late presentation with advanced stages of disease, impaired hepatic function, or local recurrence following surgical resection preclude operative management as the sole treatment modality in a subgroup of patients. As such, systemic therapies, namely immunotherapy, have become an integral part of the HCC treatment algorithm over the past decade. While agents, such as atezolizumab/bevacizumab, have well-established roles as first-line systemic therapy in intermediate- and advanced-stage HCC, the role of immunotherapy in disease amenable to surgical management continues to evolve. In this review, we will discuss the current evidence and aggregate impact of immunotherapy in the context of HCC amenable to surgical management, including its application in the neoadjuvant and adjuvant settings.

Factors affecting the compliance of hepatocellular carcinoma screening among high-risk populations: A systematic review and meta-analysis

BACKGROUND

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and the third leading cause of cancer mortality. HCC has high morbidity, high mortality, and low survival rates. Screening is one of the most significant methods of lowering incidence and death while also increasing survival.

OBJECTIVES

The aim of this study was to identify the facilitators and barriers to participation in HCC screening among high-risk populations.

METHODS

A comprehensive and systematic search was undertaken in PubMed, Web of Science, MEDLINE, EMBACE, EBSCOhost and the Cochrane Library. A combination of synonyms of the keywords including HCC, screening, factors and adherence were used for searching. Studies addressing the facilitators and barriers to HCC screening compliance in at-risk individuals were included. Data were synthesized using Review Manager version 5.4. A random/fixed effects model meta-analysis was performed to estimate the pooled data and expressed with odds ratio (OR) and 95% confidence interval (CI).

RESULTS

A total of seven articles met the inclusion criteria. Qualitative (n = 1) and quantitative (n = 6) studies using various types of surgery were conducted. The most commonly mentioned barriers were insufficient knowledge and awareness of HCC screening, unawareness of the necessity for early detection of HCC and lack of physician recommendation. A meta-analysis of seven studies showed that individuals with a family history of HCC increased screening uptake by nearly three times (OR: 2.69, 95% CI: 1.93, 3.75). Other most frequently reported facilitators include age, education level, and perceived risk et al.

CONCLUSIONS

Many barriers to HCC screening were found. Meanwhile, this review points out that improving the awareness of high-risk populations toward HCC screening is expected to enhance compliance, thereby promoting early diagnosis of liver cancer, reducing mortality, and alleviating the burden of HCC.

Pragmatic strategies to address health disparities along the continuum of care in chronic liver disease

Racial, ethnic, and socioeconomic disparities exist in the prevalence and natural history of chronic liver disease, access to care, and clinical outcomes. Solutions to improve health equity range widely, from digital health tools to policy changes. The current review outlines the disparities along the chronic liver disease health care continuum from screening and diagnosis to the management of cirrhosis and considerations of pre-liver and post-liver transplantation. Using a health equity research and implementation science framework, we offer pragmatic strategies to address barriers to implementing high-quality equitable care for patients with chronic liver disease.

Proportion of Time Covered by Hepatocellular Carcinoma Surveillance in Patients With Cirrhosis

INTRODUCTION

Hepatocellular carcinoma (HCC) surveillance is associated with improved early tumor detection, but effectiveness is limited by underuse. We characterized adherence to HCC surveillance using proportion of time covered (PTC) and estimated its association with clinical outcomes among patients with cirrhosis.

METHODS

We conducted a retrospective cohort study of patients diagnosed with HCC between January 2008 and December 2022 at 2 large US health systems. We characterized PTC by imaging in the 12 and 24 months before HCC diagnosis. We used multivariable logistic and Cox regression analyses to assess the association between PTC and early HCC detection, receipt of curative treatment, and overall survival.

RESULTS

Among 2,027 patients with HCC, 331 (51.4% Barcelona Clinic Liver Cancer 0/A) had been followed up for at least 12 months before diagnosis. The median PTC was 24.9% (interquartile range 1.1%-50.7%), with only 16.0% having semiannual imaging and 42.0% having annual surveillance. Semiannual and annual surveillance decreased to 6.3% and 29.6% when assessed over 24 months, although the median PTC remained unchanged at 24.9%. Receipt of gastroenterology/hepatology care had the strongest association with PTC, with median PTC of 36.7% and 3.8% for those with and without gastroenterology/hepatology care, respectively. PTC was independently associated with improved early HCC detection, curative treatment receipt, and overall survival. The median survival was 15.7, 26.8, and 32.7 months among those with PTC of <25% (n = 168 patients), PTC 25%-50% (n = 69 patients), and PTC >50% (n = 94 patients), respectively.

DISCUSSION

The proportion of time covered by HCC surveillance in patients with cirrhosis remains low, highlighting a need for multilevel interventions.

Race/ethnicity and socioeconomic position in emergency department utilization in patients with hepatocellular carcinoma

Aim: Evaluate the association of race/ethnicity and socioeconomic position (SEP) on emergency department (ED) visits for patients with hepatocellular carcinoma (HCC), which may reflect access to and quality of cancer care.Materials & methods: Patients with HCC identified from a commercial multi-payer claims database between 2015 and 2018 were matched to near-neighborhood social determinants of health (SDOH) and stratified by race/ethnicity and SEP (proxied by annual household income). Analyses evaluated the effect of race/ethnicity and SEP on ED utilization, adjusting for SDOH, demographic and clinical characteristics using multivariable regression methods.Results: A total of 22,247 patients were included. Black and Hispanic patients had 43 and 18% higher ED utilization than White patients at higher-income levels (p < 0.01); these differences were nonsignificant at lower-income. Regardless of income level, Asian patients had lower ED utilization.Conclusion: Further research on the intersectionality between race/ethnicity, SEP and other SDOH may guide structural-level interventions to address health inequities.

Racial and Ethnic Disparities in Hepatocellular Carcinoma Treatment Receipt in the United States: A Systematic Review and Meta-Analysis

BACKGROUND

Racial and ethnic disparities in hepatocellular carcinoma (HCC) prognosis exist, partly related to differential failures along the cancer care continuum. We characterized racial and ethnic disparities in treatment receipt among patients with HCC in the United States.

METHODS

We searched Medline, Embase, and CINAHL databases to identify studies published between January 2012 and March 2022 reporting HCC treatment receipt among adult patients with HCC, stratified by race or ethnicity. We calculated pooled odds ratios for HCC treatment using random effects models.

RESULTS

We identified 15 studies with 320,686 patients (65.8% White, 13.9% Black, 10.4% Asian, and 8.5% Hispanic). Overall, 33.2% of HCC patients underwent any treatment, and 22.7% underwent curative treatment. Compared with White patients, Black patients had lower odds of any treatment (OR 0.67, 95% CI 0.55-0.81) and curative treatment (OR 0.74, 95% CI 0.71-0.78). Similarly, Hispanic patients had lower pooled odds of curative treatment (OR 0.79, 95% CI 0.73-0.84).

CONCLUSIONS

There were significant racial and ethnic disparities in HCC treatment receipt, with Black patients having lower odds of receiving any and curative treatment while Hispanic patients having lower odds of curative treatment.

IMPACT

Racial and ethnic differences in treatment receipt serve as an intervention target to reduce disparities in HCC prognosis.

Hepatocellular Carcinoma Screening in a Contemporary Cohort of At-Risk Patients

Importance

Cohort studies demonstrating an association of hepatocellular carcinoma (HCC) screening with reduced mortality are prone to lead-time and length-time biases.

Objective

To characterize the clinical benefits of HCC screening, adjusting for lead-time and length-time biases, in a diverse, contemporary cohort of at-risk patients.

Design, Setting, and Participants

This retrospective cohort study of patients with HCC was conducted between January 2008 and December 2022 at 2 large US health systems. Data analysis was performed from September to November 2023.

Main Outcomes and Measures

The primary outcome was screen-detected HCC, defined by abnormal screening-intent abdominal imaging or α-fetoprotein level within 6 months before diagnosis. Cox regression analysis was used to characterize differences in overall survival between patients with screen-detected and non-screen-detected HCC; lead-time and length-time adjustments were calculated using the Duffy parametric formula.

Results

Among 1313 patients with HCC (mean [SD] age, 61.7 [9.6] years; 993 male [75.6%]; 739 [56.3%] with Barcelona Clinic Liver Cancer stage 0/A disease), HCC was screen-detected in 556 (42.3%) and non-screen detected in 757 (57.7%). Patients with screen-detected HCC had higher proportions of early-stage HCC (393 patients [70.7%] vs 346 patients [45.7%]; risk ratio [RR], 1.54; 95% CI, 1.41-1.70) and curative treatment receipt (283 patients [51.1%] vs 252 patients [33.5%]; RR, 1.52; 95% CI, 1.34-1.74) compared with patients with non-screen-detected HCC. The screen-detected group had significantly lower mortality, which persisted after correcting for lead-time bias (hazard ratio, 0.75; 95% CI, 0.65-0.87) in fully adjusted models. Both groups had similar tumor doubling times (median [IQR], 3.8 [2.2-10.7] vs 5.6 [1.7-11.4] months) and proportions of indolent tumors (28 patients [35.4%] vs 24 patients [38.1%]; RR, 0.93; 95% CI, 0.60-1.43). Adjustment for length-time bias decreased survival estimates, although 3-year and 5-year survival for patients with screen-detected HCC remained longer than that for patients with non-screen-detected HCC.

Conclusions and Relevance

The findings of this cohort study suggest that HCC screening is associated with reduced mortality even after accounting for lead-time and length-time biases. However, these biases should be considered in future studies.

Burden of liver cancer mortality by county, race, and ethnicity in the USA, 2000-19: a systematic analysis of health disparities

BACKGROUND

Understanding how specific populations are affected by liver cancer is important for identifying priorities, policies, and interventions to mitigate health risks and reduce disparities. This study aims to provide comprehensive analysis of rates and trends in liver cancer mortality for different racial and ethnic populations in the USA nationally and at the county level from 2000 to 2019.

METHODS

We applied small-area estimation methods to death registration data from the US National Vital Statistics System and population data from the US National Center for Health Statistics to estimate liver cancer mortality rates by county, racial and ethnic population, and year (2000-19) in the USA. Race and ethnicity were categorised as non-Latino and non-Hispanic American Indian or Alaska Native (AIAN), non-Latino and non-Hispanic Asian or Pacific Islander (Asian), non-Latino and non-Hispanic Black (Black), Latino or Hispanic (Latino), and non-Latino and non-Hispanic White (White). Estimates were adjusted using published misclassification ratios to correct for inaccuracies in race or ethnicity as recorded on death certificates, and then age-standardised. Mortality rate estimates are presented for all county and racial and ethnic population combinations with a mean annual population greater than 1000.

FINDINGS

Nationally, the age-standardised liver cancer mortality rate increased between the years 2000 (4·2 deaths per 100 000 population [95% uncertainty interval 4·1-4·3]) and 2016 (6·0 per 100 000 [5·9-6·1]), followed by a stabilisation in rates from 2016 to 2019 (6·1 per 100 000 [6·0-6·2]). Similar trends were observed across the AIAN, Black, Latino, and White populations, whereas the Asian population showed an overall decrease across the 20-year study period. Qualitatively similar trends were observed in most counties; however, the mortality rate and the rate of change varied substantially across counties, both within and across racial and ethnic populations. For the 2016-19 period, mortality continued to increase at a substantial rate in some counties even while it stabilised nationally. Nationally, the White population had the lowest mortality rate in all years, while the racial and ethnic population with the highest rate changed from the Asian population in 2000 to the AIAN population in 2019. Racial and ethnic disparities were substantial: in 2019, mortality was highest in the AIAN population (10·5 deaths per 100 000 [9·1-12·0]), notably lower for the Asian (7·5 per 100 000 [7·1-7·9]), Black (7·6 per 100 000 [7·3-7·8]), and Latino (7·7 per 100 000 [7·5-8·0]) populations, and lowest for the White population (5·5 [5·4-5·6]). These racial and ethnic disparities in mortality were prevalent throughout the country: in 2019, mortality was higher in minoritised racial and ethnic populations than in the White population living in the same county in 408 (87·7%) of 465 counties with unmasked estimates for the AIAN population, 604 (90·6%) of 667 counties for the Asian population, 1207 (81·2%) of 1486 counties for the Black population, and 1073 (73·0%) of 1469 counties for the Latino population.

INTERPRETATION

Although the plateau in liver cancer mortality rates in recent years is encouraging, mortality remains too high in many locations throughout the USA, particularly for minoritised racial and ethnic populations. Addressing population-specific risk factors and differences in access to quality health care is essential for decreasing the burden and disparities in liver cancer mortality across racial and ethnic populations and locations.

Incidence of Etiology-specific Hepatocellular Carcinoma: Diverging Trends and Significant Heterogeneity by Race and Ethnicity

BACKGROUND & AIMS

The main causes of hepatocellular carcinoma (HCC) include chronic hepatitis C and B viral infections (HCV, HBV), nonalcoholic fatty liver disease (NAFLD), and alcohol-related disease (ALD). Etiology-specific HCC incidence rates and temporal trends on a population-basis are needed to improve HCC control and prevention.

METHODS

All 14,420 HCC cases from the Florida statewide cancer registry were individually linked to data from the hospital discharge agency and the viral hepatitis department to determine the predominant etiology of each case diagnosed during 2010 to 2018. Age-adjusted incidence rates (AAIRs) were used to assess the intersection between etiology and detailed race-ethnicity. Etiology-specific temporal trends based on diagnosis year were assessed using Joinpoint regression.

RESULTS

HCV remains the leading cause of HCC among men, but since 2017 NAFLD-HCC is the leading cause among women. HCV-HCC AAIRs are particularly high among U.S.-born minority men, including Puerto Rican (10.9 per 100,000), African American (8.0 per 100,000), and U.S.-born Mexican American men (7.6 per 100,000). NAFLD is more common among all Hispanics and Filipinos and HBV-HCC among Asian and Haitian black men. HCV-HCC surpasses HBV-HCC in Asian women. ALD-HCC is high among specific Hispanic male groups. Population-based HCV-HCC rates experienced a rapid decline since 2015 (-9.6% annually), whereas ALD-HCC (+6.0%) and NAFLD-HCC (+4.3%) are rising (P < .05).

CONCLUSIONS

New direct acting anti-viral drugs have impacted rates of HCV-HCC, offsetting important increases in both ALD- and NAFLD-HCC. Hispanics may be a group of concern because of higher rates for ALD- and NAFLD-HCC. HCC etiology varies remarkably and may warrant specific interventions by detailed race-ethnicity.

Current Perspectives on the Molecular and Clinical Relationships between Primary Biliary Cholangitis and Hepatocellular Carcinoma

Primary biliary cholangitis (PBC) is an autoimmune liver disease characterised by the immune-mediated destruction of small and medium intrahepatic bile ducts, with variable outcomes and progression. This review summarises the state of the art regarding the risk of neoplastic progression in PBC patients, with a particular focus on the molecular alterations present in PBC and in hepatocellular carcinoma (HCC), which is the most frequent liver cancer in these patients. Major risk factors are male gender, viral infections, e.g., HBV and HCV, non-response to UDCA, and high alcohol intake, as well as some metabolic-associated factors. Overall, HCC development is significantly more frequent in patients with advanced histological stages, being related to liver cirrhosis. It seems to be of fundamental importance to unravel eventual dysfunctional molecular pathways in PBC patients that may be used as biomarkers for HCC development. In the near future, this will possibly take advantage of artificial intelligence-designed algorithms.

Hepatocellular Carcinoma Surveillance Patterns and Outcomes in Patients With Cirrhosis

BACKGROUND & AIMS

Hepatocellular carcinoma (HCC) surveillance is associated with improved early detection and reduced mortality, although practice patterns and effectiveness vary in clinical practice. We aimed to characterize HCC surveillance patterns in a large, diverse cohort of patients with HCC.

METHODS

We conducted a retrospective cohort study of patients diagnosed with HCC between January 2008 and December 2022 at 2 large US health systems. We recorded imaging receipt in the year before HCC diagnosis: ultrasound plus α-fetoprotein (AFP), ultrasound alone, multiphasic contrast-enhanced computed tomography (CT)/magnetic resonance imaging (MRI), and no liver imaging. We used multivariable logistic and Cox regression analysis to compare early tumor detection, curative treatment receipt, and overall survival between surveillance strategies.

RESULTS

Among 2028 patients with HCC (46.7% Barcelona Clinic Liver Cancer stage A), 703 (34.7%) had ultrasound plus AFP, 293 (14.5%) had ultrasound alone, 326 (16.1%) had multiphasic CT/MRI, and 706 (34.8%) had no imaging in the year before HCC diagnosis. Over the study period, proportions without imaging were stable, whereas use of CT/MRI increased. Compared with no imaging, CT/MRI and ultrasound plus AFP, but not ultrasound alone, were associated with early stage HCC detection and curative treatment. Compared with ultrasound alone, CT/MRI and ultrasound plus AFP were associated with increased early stage detection.

CONCLUSIONS

HCC surveillance patterns vary in clinical practice and are associated with differing clinical outcomes. While awaiting data to determine if CT or MRI surveillance can be performed in a cost-effective manner in selected patients, AFP has a complementary role to ultrasound-based surveillance, supporting its adoption in practice guidelines.

Association between Patient Experience Scores and Low Utilization of Hepatocellular Carcinoma Treatment in the United States: A Surveillance, Epidemiology, and End Results-Consumer Assessment of Healthcare Providers and Systems Analysis (SEER-CAHPS)

PURPOSE

To study the experiences of patients with hepatocellular carcinoma (HCC) contributing to treatment discrepancy in the United States.

MATERIALS AND METHODS

Using Surveillance, Epidemiology, and End Results data from National Cancer Institute (NCI), Medicare (2002-2015) beneficiaries with HCC who completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey were included. Six CAHPS items (3 global scores: global care rating [GCR], primary doctor rating [PDR], and specialist rating [SR]; 3 composite scores: getting needed care [GNC], getting care quickly [GCQ], and doctor communication [DC]) assessed patient experience. Covariates assessed between treated and nontreated groups included patient, disease, hospital, and CAHPS items.

RESULTS

Among 548 patients with HCC, 211 (39%) received treatment and 337 (61%) did not receive treatment. Forty-two percent (GCR), 29% (PDR), 30% (SR), 36% (GNC), 78% (GCQ), and 35% (DC) of patients reported less-than-excellent experiences on the respective CAHPS items. Chronic liver disease (CLD) was present in 52% and liver decompensation (LD) in 60%. A minority of the hospitals were NCI-designated cancer centers (47%), transplant centers (27%), and referral centers (9%). On univariable analysis, patients with at least a high school degree (odds ratio [OR], 1.9), admittance to a ≥400-bed hospital (OR, 2.7), CLD (OR, 3.0), or LD (OR, 1.7) were more likely to receive treatment, whereas older patients (≥75 years) (OR, 0.5) were less likely to receive treatment. On multivariable, patients with CLD (OR, 6.8) and an excellent experience in GNC with a specialist (OR, 10.6) were more likely to receive treatment.

CONCLUSIONS

HCC treatment discrepancy may be associated with patient-related factors, such as lack of specialist care (GNC), and disease-related factors, such as absence of underlying CLD.

Assessing Adherence to US LI-RADS Follow-up Recommendations in Vulnerable Patients Undergoing Hepatocellular Carcinoma Surveillance

Purpose To assess adherence to the US Liver Imaging Reporting and Data System (LI-RADS) recommendations for hepatocellular carcinoma (HCC) surveillance and associated patient-level factors in a vulnerable, diverse patient sample. Materials and Methods The radiology report database was queried retrospectively for patients who underwent US LI-RADS-based surveillance examinations at a single institution between June 1, 2020, and February 28, 2021. Initial US and follow-up liver imaging were included. Sociodemographic and clinical data were captured from electronic medical records. Adherence to radiologist recommendation was defined as imaging (US, CT, or MRI) follow-up in 5-7 months for US-1, imaging follow-up in 3-6 months for US-2, and CT or MRI follow-up in 2 months for US-3. Descriptive analysis and multivariable modeling that adjusted for age, sex, race, and time since COVID-19 pandemic onset were performed. Results Among 936 patients, the mean age was 59.1 years; 531 patients (56.7%) were male and 544 (58.1%) were Asian or Pacific Islander, 91 (9.7%) were Black, 129 (13.8%) were Hispanic, 147 (15.7%) were White, and 25 (2.7%) self-reported as other race. The overall adherence rate was 38.8% (95% CI: 35.7, 41.9). The most common liver disease etiology was hepatitis B (60.6% [657 of 936 patients]); 19.7% of patients (183 of 936) had current or past substance use disorder, and 44.8% (416 of 936) smoked. At adjusted multivariable analysis, older age (odds ratio [OR], 1.20; P = .02), male sex (OR, 1.62; P = .003), hepatology clinic attendance (OR, 3.81; P < .001), and recent prior US examination (OR, 2.44; P < .001) were associated with full adherence, while current smoking (OR, 0.39; P < .001) was negatively associated. Conclusion Adherence to HCC imaging surveillance was suboptimal, despite US LI-RADS implementation.

Conditional survival probability of distant-metastatic hepatocellular carcinoma: A population-based study

BACKGROUND

The prognosis of many patients with distant metastatic hepatocellular carcinoma (HCC) improved after they survived for several months. Compared with traditional survival analysis, conditional survival (CS) which takes into account changes in survival risk could be used to describe dynamic survival probabilities.

AIM

To evaluate CS of distant metastatic HCC patients.

METHODS

Patients diagnosed with distant metastatic HCC between 2010 and 2015 were extracted from the Surveillance, Epidemiology and End Results database. Univariate and multivariate Cox regression analysis were used to identify risk factors for overall survival (OS), while competing risk model was used to identify risk factors for cancer-specific survival (CSS). Six-month CS was used to calculate the probability of survival for an additional 6 mo at a specific time after initial diagnosis, and standardized difference (d) was used to evaluate the survival differences between subgroups. Nomograms were constructed to predict CS.

RESULTS

Positive α-fetoprotein expression, higher T stage (T3 and T4), N1 stage, non-primary site surgery, non-chemotherapy, non-radiotherapy, and lung metastasis were independent risk factors for actual OS and CSS through univariate and multivariate analysis. Actual survival rates decreased over time, while CS rates gradually increased. As for the 6-month CS, the survival difference caused by chemotherapy and radiotherapy gradually disappeared over time, and the survival difference caused by lung metastasis reversed. Moreover, the influence of age and gender on survival gradually appeared. Nomograms were fitted for patients who have lived for 2, 4 and 6 mo to predict 6-month conditional OS and CSS, respectively. The area under the curve (AUC) of nomograms for conditional OS decreased as time passed, and the AUC for conditional CSS gradually increased.

CONCLUSION

CS for distant metastatic HCC patients substantially increased over time. With dynamic risk factors, nomograms constructed at a specific time could predict more accurate survival rates.

Racial Disparities in Candidates for Hepatocellular Carcinoma Liver Transplant After 6-Month Wait Policy Change

Importance

Racial disparities in liver transplant (LT) for hepatocellular carcinoma (HCC) may be associated with unequal access to life-saving treatment.

Objective

To quantify racial disparities in LT for HCC and mortality after LT, adjusting for demographic, clinical, and socioeconomic factors.

Design, Setting, and Participants

This cohort study was a retrospective analysis of United Network Organ Sharing/Organ Procurement Transplant Network (OPTN) data from 2003 to 2021. Participants were adult patients with HCC on the LT waiting list and those who received LT. Data were analyzed from March 2022 to September 2023.

Exposures

Race and time before and after the 2015 OPTN policy change.

Main Outcomes and Measures

Proportion of LT from wait-listed candidates, the proportion of waiting list removals, and mortality after LT.

Results

Among 12 031 patients wait-listed for LT with HCC (mean [SD] age, 60.8 [7.4] years; 9054 [75.3%] male; 7234 [60.1%] White, 2590 [21.5%] Latinx/o/a, and 1172 [9.7%] Black or African American), this study found that after the 2015 model of end-stage liver disease (MELD) exception policy changes for HCC (era 2), the overall proportion of LT for HCC across all races decreased while the proportion of dropouts on the LT waiting list remained steady compared with patients who did not have HCC. In Kaplan-Meier analysis, Asian patients demonstrated the lowest dropout rates in both era 1 and era 2 (1-year dropout, 16% and 17%, respectively; P < .001). In contrast, Black or African American patients had the highest dropout rates in era 1 (1-year dropout, 24%), but comparable dropout rates (23%) with White patients (23%) and Latinx/o/a patients in era 2 (23%). In both eras, Asian patients had the highest survival after LT (5-year survival, 82% for era 1 and 86% for era 2), while Black or African American patients had the worst survival after LT (5-year survival, 71% for era 1 and 79% for era 2). In the multivariable analysis for HCC LT recipients, Black or African American race was associated with increased risk of mortality in both eras, compared with White race (HR for era 1, 1.17; 95% CI, 1.05-1.35; and HR for era 2, 1.31; 95% CI, 1.10-1.56).

Conclusions and Relevance

This cohort study of LT candidates in the US found that after the 2015 MELD exception policy change for HCC, the proportion of LT for HCC had decreased for all races. Black or African American patients had worse outcomes after LT than other races. Further research is needed to identify the underlying causes of this disparity and develop strategies to improve outcomes for HCC LT candidates.

Association Between Socioeconomic Factors, Race, and Use of a Specialty Memory Clinic

BACKGROUND AND OBJECTIVES

The capacity of specialty memory clinics in the United States is very limited. If lower socioeconomic status or minoritized racial group is associated with reduced use of memory clinics, this could exacerbate health care disparities, especially if more effective treatments of Alzheimer disease become available. We aimed to understand how use of a memory clinic is associated with neighborhood-level measures of socioeconomic factors and the intersectionality of race.

METHODS

We conducted an observational cross-sectional study using electronic health record data to compare the neighborhood advantage of patients seen at the Washington University Memory Diagnostic Center with the catchment area using a geographical information system. Furthermore, we compared the severity of dementia at the initial visit between patients who self-identified as Black or White. We used a multinomial logistic regression model to assess the Clinical Dementia Rating at the initial visit and t tests to compare neighborhood characteristics, including Area Deprivation Index, with those of the catchment area.

RESULTS

A total of 4,824 patients seen at the memory clinic between 2008 and 2018 were included in this study (mean age 72.7 [SD 11.0] years, 2,712 [56%] female, 543 [11%] Black). Most of the memory clinic patients lived in more advantaged neighborhoods within the overall catchment area. The percentage of patients self-identifying as Black (11%) was lower than the average percentage of Black individuals by census tract in the catchment area (16%) (p < 0.001). Black patients lived in less advantaged neighborhoods, and Black patients were more likely than White patients to have moderate or severe dementia at their initial visit (odds ratio 1.59, 95% CI 1.11-2.25).

DISCUSSION

This study demonstrates that patients living in less affluent neighborhoods were less likely to be seen in one large memory clinic. Black patients were under-represented in the clinic, and Black patients had more severe dementia at their initial visit. These findings suggest that patients with a lower socioeconomic status and who identify as Black are less likely to be seen in memory clinics, which are likely to be a major point of access for any new Alzheimer disease treatments that may become available.

Racial Disparities in Liver Transplantation for Hepatocellular Carcinoma in the United States: An Update

BACKGROUND

Previous studies have demonstrated a disparity in liver transplantation (LT) for hepatocellular carcinoma (HCC) among races in the United States (U.S.).

AIMS

We aimed to update the literature on the odds, trends, and complications of LT in the treatment of hepatocellular carcinoma (HCC), among individuals of different racial backgrounds.

METHODS

This is a nationwide study of adult individuals admitted for LT with a primary diagnosis of HCC. Using weighted data from the National Inpatient Sample (NIS) database, we compared the odds of LT among different races from 2016 to 2020, using a multivariate regression analysis. We further assessed the trends and outcomes of LT among races.

RESULTS

A total of 112,110 adult were hospitalized with a primary diagnosis of HCC. 3020 underwent LT. When compared to Whites, the likelihood of undergoing LT for HCC was significantly reduced in Blacks (OR = 0.60, 95% CI = 0.46-0.78). Further, Blacks had increased mortality rates (7% in Blacks vs. 1% in Whites, p < 0.001), sepsis (11% in Blacks vs. 3% in Whites, p = 0.015), and acute kidney injury (AKI) (54% in Blacks vs. 31% in Whites, p < 0.001) following LT.

CONCLUSIONS

Individuals identifying as Blacks were less likely to undergo LT for HCC, and more likely to develop complications. Further initiatives are warranted to mitigate the existing disparities among racial groups.

Dysregulation of Type I Interferon (IFN-I) Signaling: A Potential Contributor to Racial Disparity in Hepatocellular Carcinoma (HCC)

African-American (AA)/Black hepatocellular carcinoma (HCC) patients have increased incidence and decreased survival rates compared to non-Hispanic (White) patients, the underlying molecular mechanism of which is not clear. Analysis of existing RNA-sequencing (RNA-seq) data in The Cancer Genome Atlas (TCGA) and in-house RNA-sequencing of 14 White and 18 AA/Black HCC patients revealed statistically significant activation of type I interferon (IFN-I) signaling pathway in AA/Black patients. A four-gene signature of IFN-stimulated genes (ISGs) showed increased expression in AA/Black HCC tumors versus White. HCC is a disease of chronic inflammation, and IFN-Is function as pro-inflammatory cytokines. We tested efficacy of ginger extract (GE), a dietary compound known for anti-inflammatory properties, on HCC cell lines derived from White (HepG2), AA/Black (Hep3B and O/20) and Asian (HuH-7) patients. GE exhibited a significantly lower IC50 on Hep3B and O/20 cells than on HepG2 and HuH-7 cells. The GE treatment inhibited the activation of downstream mediators of IFN-I signaling pathways and expression of ISGs in all four HCC cells. Our data suggest that ginger can potentially attenuate IFN-I-mediated signaling pathways in HCC, and cells from AA/Black HCC patients may be more sensitive to ginger. AA/Black HCC patients might benefit from a holistic diet containing ginger.

Prevention of Hepatocellular Carcinoma (HCC). White Paper of the Texas Collaborative Center for Hepatocellular Cancer (TeCH) Multi-stakeholder Conference

BACKGROUND & AIMS

Texas has the highest age-adjusted incidence rate of hepatocellular carcinoma (HCC) in the United States. The Cancer Prevention and Research Institute of Texas has funded the Texas Collaborative Center for Hepatocellular Cancer (TeCH) to facilitate HCC research, education, and advocacy activities with the overall goal of reducing HCC mortality in Texas through coordination, collaboration, and advocacy.

METHODS

On September 17, 2022, TeCH co-sponsored a multi-stakeholder conference on HCC with the Baker Institute Center for Health and Biosciences. This conference was attended by HCC researchers, policy makers, payers, members from pharmaceutical industry and patient advocacy groups in and outside of Texas. This report summarizes the results of the conference.

RESULTS

The goal of this meeting was to identify different strategies for preventing HCC and evaluate their readiness for implementation.

CONCLUSIONS

We call for a statewide (1) viral hepatitis elimination program; (2) program to increase nonalcoholic steatohepatitis and obesity awareness; (3) research program to develop health care models that integrate alcohol associated liver disease treatment and treatment for alcohol use disorder; and (4) demonstration projects to evaluate the effectiveness of identifying and linking patient with advanced fibrosis and cirrhosis to clinical care.

Gender Differences in the Pathogenesis and Risk Factors of Hepatocellular Carcinoma

Several chronic liver diseases are characterized by a clear gender disparity. Among them, hepatocellular carcinoma (HCC) shows significantly higher incidence rates in men than in women. The different epidemiological distribution of risk factors for liver disease and HCC only partially accounts for these gender differences. In fact, the liver is an organ with recognized sexual dysmorphism and is extremely sensitive to the action of androgens and estrogens. Sex hormones act by modulating the risk of developing HCC and influencing its aggressiveness, response to treatments, and prognosis. Furthermore, androgens and estrogens are able to modulate the action of other factors and cofactors of liver damage (e.g., chronic HBV infection, obesity), significantly influencing their carcinogenic power. The purpose of this review is to examine the factors related to the different gender distribution in the incidence of HCC as well as the pathophysiological mechanisms involved, with particular reference to the central role played by sex hormones.

Association of nativity with survival among adults with hepatocellular carcinoma

INTRODUCTION

Immigrants comprise a considerable proportion of those diagnosed with hepatocellular carcinoma (HCC) in the United States. Nativity or birthplace affects incidence and risk factors for HCC, but little is known about its influence on survival after diagnosis.

METHODS

We identified 51 533 adults with HCC with available birthplace in the California Cancer Registry between 1988 and 2017. HCC cases were categorized as foreign born or US born and stratified by mutually exclusive race and ethnicity groups. Primary outcome was all-cause mortality. Race and ethnicity-specific Cox regression propensity score-weighted models evaluated the relationship between nativity and death as well as region of birth among foreign-born patients.

RESULTS

A total of 40% of all HCC cases were foreign born, and 92.2%, 45.2%, 9.1%, and 5.8% of Asian/Pacific Islander (API), Hispanic, White, and Black patients were foreign born, respectively. Five-year survival rates were higher in foreign-born patients compared with US-born patients: 12.9% vs 9.6% for White patients, 11.7% vs 9.8% for Hispanic patients, 12.8% vs 8.1% for Black patients, and 16.4% vs 12.4% for API patients. Nativity was associated with survival, with better survival in foreign-born patients: White patients: hazard ratio (HR) = 0.86 (95% confidence interval [CI] = 0.81 to 0.90), Hispanic patients: HR = 0.90 (95% CI = 0.86 to 0.93), Black patients: HR = 0.89 (95% CI = 0.76 to 1.05), and API patients: HR = 0.94 (95% CI = 0.88 to 1.00). Among foreign-born patients, lower mortality was observed in those from Central and South America compared with Mexico for Hispanic patients, East Asia compared with Southeast Asia for API patients, and East Europe and Greater Middle East compared with West/South/North Europe for White patients.

CONCLUSION

Foreign-born patients with HCC have better survival than US-born patients. Further investigation into the mechanisms of this survival disparity by nativity is needed.

Actionable Solutions to Achieve Health Equity in Chronic Liver Disease

There are well-described racial and ethnic disparities in the burden of chronic liver diseases. Hispanic persons are at highest risk for developing nonalcoholic fatty liver disease, the fastest growing cause of liver disease. Hepatitis B disproportionately affects persons of Asian or African descent. The highest rates of hepatitis C occur in American Indian and Alaskan Native populations. In addition to disparities in disease burden, there are also marked racial and ethnic disparities in access to treatments, including liver transplantation. Disparities also exist by gender and geography, especially in alcohol-related liver disease. To achieve health equity, we must address the root causes that drive these inequities. Understanding the role that social determinants of health play in the disparate health outcomes that are currently observed is critically important. We must forge and/or strengthen collaborations between patients, community members, other key stakeholders, health care providers, health care institutions, professional societies, and legislative bodies. Herein, we provide a high-level review of current disparities in chronic liver disease and describe actionable strategies that have potential to bridge gaps, improve quality, and promote equity in liver care.

Addressing racial and ethnic disparities in US liver cancer care

HCC, the most common form of primary liver cancer, is the fastest rising cause of cancer-related death in the United States. HCC disproportionately affects racial and ethnic minorities in the United States. A practical framework is needed to organize the complex patient, provider, health system, and societal factors that drive these racial and ethnic disparities. In this narrative review, we adapted and applied the National Institute on Minority Health and Health Disparities (NIMHD) Research Framework to the HCC care continuum, as a step toward better understanding and addressing existing HCC-related disparities. We first summarize the literature on HCC-related disparities by race and ethnicity organized by the framework's 5 domains (biological, behavioral, physical/built environment, sociocultural environment, and health care system) and 4 levels (individual, interpersonal, community, and societal) of influence. We then offer strategies to guide future research initiatives toward promotion of health equity in HCC care. Clinicians and researchers may help mitigate further inequities and better address racial and ethnic disparities in HCC care by prioritizing the following in HCC research: (1) increasing racial and ethnic minority representation, (2) collecting and reporting HCC-related data by racial and ethnic subgroups, (3) assessing the patient experience of HCC care by race and ethnicity, and (4) evaluating HCC-specific social determinants of health by race and ethnicity. These 4 priorities will help inform the development of future programs and interventions that are tailored to the unique experiences of each racial and ethnic group.

Qualitative evaluation of barriers and facilitators to hepatocellular carcinoma care in North Carolina

BACKGROUND

Many patients with hepatocellular carcinoma (HCC) never receive cancer-directed therapy. In order to tailor interventions to increase access to appropriate therapy, we sought to understand the barriers and facilitators to HCC care.

METHODS

Patients with recently diagnosed HCC were identified through the University of North Carolina (UNC) HCC clinic or local hospital cancer registrars (rapid case ascertainment, RCA). Two qualitative researchers conducted in-depth, semi-structured interviews. Interviews were audiotaped, transcribed, and coded.

RESULTS

Nineteen interviews were conducted (10 UNC, 9 RCA). Key facilitators of care were: physician knowledge; effective communication regarding test results, plan of care, and prognosis; social support; and financial support. Barriers included: lack of transportation; cost of care; provider lack of knowledge about HCC; delays in scheduling; or poor communication with the medical team. Participants suggested better coordination of appointments and having a primary contact within the healthcare team.

LIMITATIONS

We primarily captured the perspectives of those HCC patients who, despite the challenges they describe, were ultimately able to receive HCC care.

CONCLUSIONS

This study identifies key facilitators and barriers to accessing care for HCC in North Carolina. Use of the RCA system to identify patients from a variety of settings, treated and untreated, enabled us to capture a broad range of perspectives. Reducing barriers through improving communication and care coordination, assisting with out-of-pocket costs, and engaging caregivers and other medical providers may improve access. This study should serve as the basis for tailored interventions aimed at improving access to appropriate, life-prolonging care for patients with HCC.

Ethnic disparities in the epidemiology, treatment, and outcome of patients with hepatocellular carcinoma in the United States

There are significant ethnic disparities in incidence, tumor stage, curative therapy receipt, and survival among patients with hepatocellular carcinoma (HCC) in the US. While previous models had predicted an increasing trend in the incidence rate of HCC until 2030 in the US, recent studies have shown that HCC incidence plateaued in 2013 and then started to decline in 2015. The decreasing trend has been observed in all ethnicities except for American Indians/Alaska Natives, whose incidence rates of HCC continue to rise. Current evidence shows that African-Americans and Hispanics are two groups that are more likely to be diagnosed with late-stage HCC, and this finding has been consistent in different socioeconomic statuses of the patients. These two ethnic minority groups are also among those who are less likely to have curative therapy for early-stage HCC. Finally, advances in early diagnosis and treatment approaches have led to an improvement in HCC survival for all ethnicities; however, African-Americans continue to have the worst survival. More studies to find the causes of these disparities and interventions to eliminate them are urgently needed.
