Description:Objective:
Hepatoblastoma (HB) is the most common pediatric primary malignant liver tumor, its incidence has been increasing worldwide, but recent changes in incidence and outcomes with high population coverage are not well characterized.
Methods:
We defined the incidence of HB diagnosed during 2003–2017 from United States Cancer Statistics (USCS) database, and survival during 2001–2016 from the National Program of Cancer Registries (NPCR). Data were stratified by sex, race/ethnicity, age, tumor stage, county population, and diagnosis year. Incidence trends were assessed by calculating average annual percent change (AAPC) using Joinpoint regression. Differences in overall 5-year survival were estimated using Cox regression analysis.
Results:
2178 HB cases with an annual incidence rate of 1.76 per million persons were identified and incidence increased over time (AAPC = 2.2, 95% confidence interval [CI], 0.9–3.6). The 5-year relative survival was 76.9% (95% CI: 74.9–78.8) and the risk of death was lower for cases diagnosed after 2009 (hazard ratio [HR] = 0.77, 95% CI: 0.63–0.94), higher for ages 3–7 years and 8–19 years compared to 0–2 years (HR = 1.38, 95% CI: 1.10–1.76 and 1.83, 95% CI: 1.31–2.70, respectively), for distant compared to locoregional stage (HR = 2.77, 95% CI: 2.27–3.36), and for non-Hispanic Black compared to non-Hispanic White cases (HR = 1.39, 95% CI: 1.02–1.84).
Conclusions:
HB incidence increased, and survival improved over the study period. Disparities in survival exist by age, race or ethnicity, and stage. Further studies could identify factors affecting increases in HB cases, inform future interventions, and address disparities in outcomes.
