Epidemiology of Hepatocellular Carcinoma in Taiwan

Abstract

Background: Hepatocellular carcinoma (HCC) is a major contributor to the world’s cancer burden. Understanding the HCC incidence rate in Taiwan is thus an interesting avenue of research. Methods: From an NHI database, those patients who had been newly diagnosed with HCC and who had been listed on a registry in a catastrophic illness dataset during the years 2013–2021 were enrolled in this study. Antineoplastic agent usage and comorbidities were also studied. Results: The incidence rate of HCC decreased from 57.77 to 44.95 in 100,000 from 2013 to 2021. The average age of patients with HCC increased from 65.54 years old with a CCI score of 4.98 in 2013 to 67.92 years old with a CCI score of 5.49 in 2021. Among these HCC patients, the patients under antineoplastic agent treatment decreased from 53.47% to 31.41% from 2013 to 2021. The presence of comorbidities in HCC patients was about 55.77–83.01% with mild liver disease and 29.93–37.30% with diabetes (without complications) in the period 2013–2021. Conclusions: The incidence rate of HCC slightly decreased in Taiwan. Due to antineoplastic agent usage decreasing over time, these results may indicate that more early-stage HCC patients detected in recent years were mainly treated with surgeries.
