Liver cancer in 2021: Global Burden of Disease study
Abstract
Background & aims: The epidemiology of adult primary liver cancer continues to evolve, owing to the increasing prevalence of metabolic disease, rising alcohol consumption, advances in vaccination for HBV, and antiviral therapy for HCV. Disparities in care and the burden of liver cancer between populations persist. We assess trends in the burden of liver cancer and contributions by various etiologies across 204 countries and territories from 2010 to 2021.
Methods: Utilizing the methodological framework of the Global Burden of Disease Study 2021, we analyzed global and regional temporal trends in incidence and mortality, and the contributions of various etiologies of liver disease.
Results: In 2021, there were an estimated 529,202 incident cases and 483,875 deaths related to liver cancer. From 2010 to 2021, global liver cancer incident cases and deaths increased by 26% and 25%, respectively. Age-standardized incidence rates (ASIRs) and death rates (ASDRs) for liver cancer declined globally, but rose in the Americas and Southeast Asia. HBV remained the dominant cause of global incident liver cancer cases and deaths. MASLD (metabolic dysfunction-associated steatotic liver disease) was the only etiology of liver cancer with rising ASIRs and ASDRs. By contrast, ASIRs and ASDRs remained stable for alcohol-related liver cancer, and declined for HBV- and HCV-related liver cancer.
Conclusions: While age-adjusted incidence and deaths from liver cancer have started to decline, the absolute number of incident cases and deaths continues to increase. Population growth and aging contribute to the observed disconnect in the temporal trends of absolute cases and rates. Disparities remain, and the incidence and mortality associated with MASLD-related liver cancer continue to rise.
Impact and implications: Liver cancer remains a major cause of death globally, but its causes and burden in various regions are changing. This study highlights that new diagnoses and deaths related to liver cancer continue to rise. Age-adjusted death rates of liver cancer related to viral hepatitis are declining but remain high. By contrast, age-adjusted death rates of liver cancer related to MASLD (metabolic dysfunction-associated steatotic liver disease) are rising. Sustained efforts and resources are needed to eliminate viral hepatitis, reverse current trends in heavy alcohol use, and tackle the metabolic risk factors of MASLD.
