ARTICLE HIGHLIGHTS
Research background

Primary liver cancer (PLC) is a common cancer with high morbidity and mortality rates. PLC usually occurs as a preventable disease. Data on global and country-specific levels and trends of PLC are essential for understanding the effects of this disease and helping policymakers to allocate resources.

Research motivation

The association between socioeconomic development status and attributable etiologies for PLC is still unclear.

Research objectives

To investigate the association between the burden of PLC and socioeconomic development status.

Research methods

Cancer mortality and incidence rates of PLC were obtained from the Global Burden of Disease (GBD) 2019, and the data were stratified by the Socio-demographic Index (SDI) level. The association between the attributable etiology of PLC and SDI was described.

Research results

Several countries located in East Asia, South Asia, West Africa, and North Africa shouldered the heaviest burden of PLC in 2019. In terms of incidence rates, the first leading underlying cause of PLC identified was hepatitis B. The incidence rate of PLC was the highest for high and middle SDI locations. The leading attributable etiologies of PLC were hepatitis B for the middle and high middle SDI locations and hepatitis C and nonalcoholic steatohepatitis for the high SDI locations.

Research conclusions

Socioeconomic development status significantly affects attributable etiologies for PLC.

Research perspectives

Our findings are valuable to implement tailored prevention strategies for PLC.
