S2739 Mortality Trends From Liver Failure in Patients With Hepatic Neoplasms: CDC Data Analysis, 1999 to 2020

Introduction: Hepatic neoplasms complicated by hepatic failure are major contributors to liver-related mortality in the United States. Their evolving burden, influenced by viral hepatitis, alcohol use, and metabolic disorders, underscores the need for stratified trend analyses to inform targeted public health interventions. Methods: A retrospective analysis used CDC data from 1999 to 2020. AAMRs per 100,000 were calculated for individuals aged ≥25 years. Joinpoint regression evaluated trends, estimating annual percent change (APC) and average annual percent change (AAPC) with 95% confidence intervals. Analyses were stratified by year, age, sex, race/ethnicity, region, and urbanization. Results: From 1999–2020, hepatic neoplasm and hepatic failure–related mortality accounted for 37,465 deaths in the United States, with AAMR declining from 0.90 to 0.68 per 100,000 (AAPC: –0.95; 95% CI: –1.22 to –0.58; P < 0.000001). Crude mortality rates declined across most age groups, with the largest relative decrease among those aged 35–44 (AAPC: –2.93), then 85+ (–2.43) and 75–84 (–1.57). An insignificant trend was seen among those aged 55–64 (0.72), 65–74 (–0.24), and 45–54 (–3.80). By sex, man AAMR declined from 1.41 to 1.05 (–1.01; P = 0.0004), and woman AAMR from 0.49 to 0.37 (–1.19; P < 0.000001). Men accounted for 27,036 (72.1%) deaths, women for 10,429 (27.9%). Among racial groups, Asian or Pacific Islanders had the steepest decline, with AAMR falling from 3.04 to 0.91 (–5.62; P < 0.000001). Hispanic individuals dropped from 1.85 to 1.12 (–1.76; P < 0.000001), while White and Black individuals declined more modestly (–0.60 and –0.63, respectively). Regionally, the West had the greatest reduction, from 1.28 to 0.83 (–1.71; P < 0.000001), then the Northeast (–1.01). The Midwest and South had flatter, insignificant declines (–0.55 and –0.32). By urbanization, large central metro areas declined from 1.13 to 0.66 (–2.08; P < 0.000001), then large fringe metros (–1.01). Small metro and micropolitan areas showed increasing trends (0.77 and 0.87), while noncore areas remained stable (–0.05). Conclusion: Hepatic failure–related mortality among patients with hepatic neoplasms declined overall from 1999 to 2020, especially among younger adults, women, Asian or Pacific Islanders, and residents of the West and large metro areas. Stable or rising trends in some age and geographic groups call for targeted interventions. AI tools were used to enhance writing clarity.
