RESUMO
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.

BACKGROUND: Among patients with cirrhosis, it remains unclear whether there are racial/ethnic differences in cirrhosis complications and mortality. We examined the associations between race/ethnicity and risk for hepatocellular carcinoma (HCC), cirrhosis decompensation, and all-cause mortality overall and by cirrhosis etiology. METHODS: US Veterans diagnosed with cirrhosis from 2001 to 2014 (n = 120,992), due to hepatitis C virus (HCV; n = 55,814), alcohol-associated liver disease (ALD; n = 36,323), hepatitis B virus (HBV; n = 1,972), nonalcoholic fatty liver disease (NAFLD; n = 17,789), or other (n = 9,094), were followed through 2020 for incident HCC (n = 10,242), cirrhosis decompensation (n = 27,887), and mortality (n = 81,441). Multivariable Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). RESULTS: Compared with non-Hispanic White patients, Hispanic patients had higher risk for HCC overall (aHR, 1.32; 95% CI, 1.24-1.41) and by cirrhosis etiology, particularly for ALD- (aHR, 1.63; 95% CI, 1.42-1.87) and NAFLD-cirrhosis (aHR, 1.76; 95% CI, 1.41-2.20), whereas non-Hispanic Black patients had lower HCC risk in ALD- (aHR, 0.79; 95% CI, 0.63-0.98) and NAFLD-cirrhosis (aHR, 0.54; 95% CI, 0.33-0.89). Asian patients had higher HCC risk (aHR, 1.70; 95% CI, 1.29-2.23), driven by HCV- and HBV-cirrhosis. Non-Hispanic Black patients had lower risk for cirrhosis decompensation overall (aHR, 0.71; 95% CI, 0.68-0.74) and by cirrhosis etiology. There was lower risk for mortality among all other racial/ethnic groups compared with non-Hispanic White patients. CONCLUSIONS: Race/ethnicity is an important predictor for risk of developing HCC, decompensation, and mortality. IMPACT: Future research should examine factors underlying these racial/ethnic differences to inform prevention, screening, and treatment for patients with cirrhosis.

BACKGROUND & AIMS: Hepatitis C virus (HCV) eradication with direct-acting antivirals reduces hepatocellular carcinoma (HCC) risk. Pooled HCC incidence rates by cirrhosis status and fibrosis stage have not been estimated using meta-analysis. METHODS: We searched PubMed, Web of Science, Embase, and Cochrane Library from January 1, 2014 to December 31, 2020 to identify studies assessing HCC incidence or outcomes by cirrhosis status, in adults with HCV who achieved sustained virologic response (SVR) after direct-acting antivirals. Pooled estimates were obtained using random-effects modeling. Subgroup, sensitivity, and meta-regression analyses were performed to evaluate heterogeneity. RESULTS: We included 31 studies involving 27,711 patients with cirrhosis (mean follow-up, 2.1 years) and 11 studies involving 32,123 patients without cirrhosis (mean follow-up, 2.6 years). HCC incidence was 2.99/100 person-years (95% confidence interval [CI], 2.52-3.54; I2 = 75%) in patients with cirrhosis, 0.47/100 person-years (95% CI, 0.32-0.70, I2 = 71%) in patients without cirrhosis, and 0.63/100 person-years (95% CI: 0.34-1.20, I2 = 0%) in stage 3 (F3) fibrosis. Among patients with cirrhosis, HCC incidence was highest in studies with <1 year of follow-up (6.17/100 person-years [95% CI, 3.73-10.19]) and progressively lower in studies with longer follow-up (1-2 years: 2.75/100 person-years [95% CI, 2.48-3.06]; 2-3 years: 2.90/100 person-years [95% CI, 1.90-4.44]; ≥3 years: 1.83/100 person-years [95% CI, 0.88-3.80]). CONCLUSION: Pooled HCC incidence after SVR in patients with cirrhosis was very high (2.99/100 person-years) but may be declining as longer time accrues after SVR. In patients without cirrhosis, including F3 fibrosis, HCC incidence was lower than thresholds associated with cost-effective HCC screening. In patients with F3 fibrosis, the lack of between-study heterogeneity provides strong evidence that HCC screening may not be warranted.
