Primary liver cancer is the third leading cause of cancer-related mortality. The increasing prevalence of metabolic syndrome and alcohol consumption, along with the existing burden of viral hepatitis, could significantly heighten the impact of primary liver cancer. However, the specific effects of these factors in the Asia–Pacific region, which comprises more than half of the global population, remain largely unexplored. This study aims to analyze the epidemiology of primary liver cancer in the Asia–Pacific region. We evaluated regional and national data from the Global Burden of Disease study spanning 2010 to 2019 to assess the age-standardized incidence, mortality, and disability-adjusted life years associated with primary liver cancer in the Asia–Pacific region. During the study period, there were an estimated 364,700 new cases of primary liver cancer and 324,100 deaths, accounting for 68 and 67% of the global totals, respectively. Upward trends were observed in the age-standardized incidence rates of primary liver cancer due to metabolic dysfunction-associated fatty liver disease (MASLD) and alcohol-associated liver disease (ALD) in the Asia–Pacific region, as well as an increase in primary liver cancer from Hepatitis B virus infection in the Western Pacific region. Notably, approximately 17% of new cases occurred in individuals aged 15–49 years. Despite an overall decline in the burden of primary liver cancer in the Asia–Pacific region over the past decade, increases in incidence were noted for several etiologies, including MASLD and ALD. However, viral hepatitis remains the leading cause, responsible for over 60% of the total burden. These findings underscore the urgent need for comprehensive strategies to address the rising burden of primary liver cancer in the Asia–Pacific region.
