Racial and Ethnic Differences in Presentation and Outcomes of Hepatocellular Carcinoma.

ABSTRACT: BACKGROUND & AIMS:Racial and ethnic minorities are reported to have higher mortality related to hepatocellular carcinoma (HCC) than non-Hispanic whites. However, it is not clear whether differences in tumor characteristics or liver dysfunction among racial or ethnic groups affect characterization of causes for this disparity. We aimed to characterize racial and ethnic differences in HCC presentation, treatment, and survival. METHODS:We performed a retrospective study of patients diagnosed with HCC from January 2008 through July 2017 at 2 large health systems in the United States. We used multivariable logistic regression and Cox proportional hazard models to identify factors associated with receipt of curative therapy and overall survival. RESULTS:Among 1117 patients with HCC (35.9% white, 34.3% black, 29.7% Hispanic), 463 (41.5%) were diagnosed with early stage HCC (Barcelona Clinic Liver Cancer stage 0/A) and 322 (28.8%) underwent curative treatment. Hispanic (odds ratio [OR], 0.75; 95% CI, 0.55-1.00) and black patients (OR, 0.74; 95% CI, 0.56-0.98) were less likely to be diagnosed with early stage HCC than white patients. Among patients with early stage HCC, Hispanics were less likely to undergo curative treatment than whites (OR, 0.58; 95% CI, 0.36-0.91). Black patients with early stage HCC were also less likely to undergo curative treatment than white patients, but this difference was not statistically significant (OR, 0.66; 95% CI, 0.43-1.03). Black and Hispanic patients had shorter median survival times than white patients (10.6 and 14.4 mo vs 16.3 mo). After adjusting for type of medical insurance, Child-Pugh class, Barcelona Clinic Liver Cancer stage, and receipt of HCC treatment, black patients had significantly higher mortality (hazard ratio, 1.12; 95% CI, 1.10-1.14) and Hispanic patients had lower mortality (hazard ratio, 0.83; 95% CI, 0.74-0.94) than white patients. CONCLUSIONS:In a retrospective study of patients diagnosed with HCC, we found racial/ethnic differences in outcomes of HCC to be associated with differences in detection of tumors at early stages and receipt of curative treatment. These factors are intervention targets for improving patient outcomes and reducing disparities.

Project description:IntroductionHepatocellular carcinoma disproportionately affects minorities. Southern states have high proportions of black populations and prevalence of known risk factors. Further research is needed to understand the role of southern geography in hepatocellular carcinoma disparities. This paper examined racial disparities in hepatocellular carcinoma incidence, demographics, tumor characteristics, receipt of treatment, and all-cause mortality in southern and non-southern cancer registries.MethodsSurveillance Epidemiology and End Results data were probed in 2015 to identify 43,868 patients diagnosed with hepatocellular carcinoma from 2000 to 2012 (5,455 in southern registries [Atlanta, Louisiana, and Rural and Greater Georgia]).ResultsSouthern registries showed steeper increases of age-adjusted hepatocellular carcinoma incidence (from 2.89 to 5.29cases/100,000 people) versus non-southern areas (from 3.58 to 5.54cases/100,000 people). Blacks were over-concentrated in southern registries (32% vs 10%). Compared with whites, blacks were significantly younger at diagnosis, more likely diagnosed with metastasis, and less likely to receive surgical therapies in both registry groups. After adjustment, blacks had a significantly higher risk of all-cause mortality compared with whites in southern (hazard ratio=1.10, p=0.007) and non-southern areas (hazard ratio=1.08, p<0.001). For overall populations, southern registries had higher risk of all-cause mortality versus non-southern registries (hazard ratio=1.13, p<0.001).ConclusionsAge-adjusted incidence rates of hepatocellular carcinoma are plateauing overall, but are still rising in southern areas. Race and geography had independent associations with all-cause mortality excess risk among patients with hepatocellular carcinoma. Further studies are needed to understand the root causes of potential mortality risk excess among overall populations with hepatocellular carcinoma living in the South.Supplement informationThis article is part of a supplement entitled African American Men's Health: Research, Practice, and Policy Implications, which is sponsored by the National Institutes of Health.

Project description:ImportanceIndividuals of racial and ethnic minority groups may be less likely to use telemedicine in part due to lack of access to technology (ie, digital divide). To date, some studies have found less telemedicine use by individuals of racial and ethnic minority groups compared with White individuals, and others have found the opposite. What explains these different findings is unclear.ObjectiveTo quantify racial and ethnic differences in the receipt of telemedicine and total visits with and without accounting for demographic and clinical characteristics and geography.Design, setting, and participantsThis cross-sectional study included individuals who were continuously enrolled in traditional Medicare from March 2020 to February 2022 or until death.ExposureRace and ethnicity, which was categorized as Black non-Hispanic, Hispanic, White non-Hispanic, other (defined as American Indian/Pacific Islander, Alaska Native, and Asian), and unknown/missing.Main outcomes and measuresTotal telemedicine visits (audio-video or audio); total visits (telemedicine or in-person) per individual during the study period. Multivariable models were used that sequentially adjusted for demographic and clinical characteristics and geographic area to examine their association with differences in telemedicine and total visit utilization by documented race and ethnicity.ResultsIn this national sample of 14 305 819 individuals, 7.4% reported that they were Black, 5.6% Hispanic, and 4.2% other race. In unadjusted results, compared with White individuals, Black individuals, Hispanic individuals, and individuals of other racial groups had 16.7 (95% CI, 16.1-17.3), 32.9 (95% CI, 32.3-33.6), and 20.9 (95% CI, 20.2-21.7) more telemedicine visits per 100 beneficiaries, respectively. After adjustment for clinical and demographic characteristics and geography, compared with White individuals, Black individuals, Hispanic individuals, and individuals of other racial groups had 7.9 (95% CI, -8.5 to -7.3), 13.2 (95% CI, -13.9 to -12.6), and 9.2 (95% CI, -10.0 to -8.5) fewer telemedicine visits per 100 beneficiaries, respectively. In unadjusted and fully adjusted models, and in 2019 and the second year of the COVID-19 pandemic, Black individuals, Hispanic individuals, and individuals of other racial groups continued to have fewer total visits than White individuals.Conclusions and relevanceThe results of this cross-sectional study of US Medicare enrollees suggest that although nationally, Black individuals, Hispanic individuals, and individuals of other racial groups received more telemedicine visits during the pandemic and disproportionately lived in geographic regions with higher telemedicine use, after controlling for geographic region, Black individuals, Hispanic individuals, and individuals of other racial groups received fewer telemedicine visits than White individuals.

Project description:Background: The COVID-19 pandemic has exposed longstanding racial/ethnic inequities in health risks and outcomes in the U.S.. We sought to identify racial/ethnic differences in presentation and outcomes for patients hospitalized with COVID-19. Methods: The American Heart Association COVID-19 Cardiovascular Disease Registry is a retrospective observational registry capturing consecutive patients hospitalized with COVID-19. We present data on the first 7,868 patients by race/ethnicity treated at 88 hospitals across the US between 01/17/2020 and 7/22/2020. The primary outcome was in-hospital mortality; secondary outcomes included major adverse cardiovascular events (MACE: death, myocardial infarction, stroke, heart failure) and COVID-19 cardiorespiratory ordinal severity score (worst to best: death, cardiac arrest, mechanical ventilation with mechanical circulatory support, mechanical ventilation with vasopressors/inotrope support, mechanical ventilation without hemodynamic support, and hospitalization without any of the above). Multivariable logistic regression analyses were performed to assess the relationship between race/ethnicity and each outcome adjusting for differences in sociodemographic, clinical, and presentation features, and accounting for clustering by hospital. Results: Among 7,868 patients hospitalized with COVID-19, 33.0% were Hispanic, 25.5% were non-Hispanic Black, 6.3% were Asian, and 35.2% were non-Hispanic White. Hispanic and Black patients were younger than non-Hispanic White and Asian patients and were more likely to be uninsured. Black patients had the highest prevalence of obesity, hypertension, and diabetes. Black patients also had the highest rates of mechanical ventilation (23.2%) and renal replacement therapy (6.6%) but the lowest rates of remdesivir use (6.1%). Overall mortality was 18.4% with 53% of all deaths occurring in Black and Hispanic patients. The adjusted odds ratios (ORs) for mortality were 0.93 (95% confidence interval [CI] 0.76-1.14) for Black patients, 0.90 (95% CI 0.73-1.11) for Hispanic patients, and 1.31 (95% CI 0.96-1.80) for Asian patients compared with non-Hispanic White patients. The median OR across hospitals was 1.99 (95% CI 1.74-2.48). Results were similar for MACE. Asian patients had the highest COVID-19 cardiorespiratory severity at presentation (adjusted OR 1.48, 95% CI 1.16-1.90). Conclusions: Although in-hospital mortality and MACE did not differ by race/ethnicity after adjustment, Black and Hispanic patients bore a greater burden of mortality and morbidity due to their disproportionate representation among COVID-19 hospitalizations.
