Abstract

With recent improvements in the treatment of end-stage liver disease (ESLD), a better understanding of the burden of cirrhosis and hepatocellular carcinoma (HCC) is needed in the United States (US). A population-based study using the US Census and national mortality database was performed. We identified the age-standardized etiology-specific mortality rates for cirrhosis and HCC among US adults aged = 20 years from 2007 to 2016. We determined temporal mortality rate patterns by joinpoint analysis with estimates of annual percentage change (APC). Age-standardized cirrhosis-related mortality rates increased from 19.77/100,000 persons in 2007 to 23.67 in 2016 with an annual increase of 2.3% (95% CI 2.0-2.7). The APC in mortality rates for hepatitis C virus (HCV)-cirrhosis shifted from a 2.9% increase per year during 2007-2014 to a 6.5% decline per year during 2014-2016. Meanwhile, mortality for cirrhosis from alcoholic liver disease (ALD, APC 4.5%) and nonalcoholic fatty liver disease (NAFLD, APC 15.4%) increased over the same period, while mortality for hepatitis B virus (HBV)-cirrhosis decreased with an average APC of -1.1%. HCC-related mortality increased from 3.48/100,000 persons in 2007 to 4.41 in 2016 at an annual rate of 2.0% (95% CI 1.3-2.6). Etiology-specific mortality rates of HCC were largely consistent with cirrhosis-related mortality. Minority populations had a higher burden of HCC-related mortality.CONCLUSION: Cirrhosis- and HCC-related mortality rates increased between 2007 and 2016 in the US. However, mortality rates in HCV-cirrhosis demonstrated a significant decline from 2014-2016, during the direct-acting antiviral era. Mortality rates for ALD/NAFLD-cirrhosis and HCC have continued to increase, while HBV-cirrhosis-related mortality declined during the 10-year period. Importantly, minorities had a disproportionately higher burden of ESLD-related mortality. This article is protected by copyright. All rights reserved.
