Abstract
Background The incidence of primary liver cancer (PLC) continues to increase worldwide. The incidence trends and patterns of PLC associated with different age at diagnosis remain unknown. Methods We collected detailed information on PLC between 1990 and 2017 from Global Burden of Disease Study 2017. Estimated annual percentage changes in the PLC age-standardized incidence rate (ASR) diagnosed by age, sex, region, and etiology were calculated to quantify the temporal trends in PLC ASR. Results Globally, the number of PLC cases for which the age at diagnosis was = 60 years old increased from 216,561 and 241,189 in 1990 to 359,770 and 578,344 in 2017, respectively. The ASR of PLC cases with age at diagnosis = 60 years increased in males and remained stable in females at the global level. Males had a more dramatic increase in PLC diagnosed at age >= 60 years but a milder decrease in PLC diagnosed between 30 and 59 years of age. This decrease was attributed largely to the reduction in PLC caused by hepatitis B and hepatitis C and was consistent in most regions except for developed countries, in which the ASR of PLC increased irrespective of sex and age. The ASR of PLC due to nonalcoholic steatohepatitis (NASH) increased by the greatest magnitude in most regions. Conclusion PLC in highly endemic regions has been partly alleviated due to the potent control of hepatitis, especially among young and middle-aged people. However, an unfavorable trend was observed in most developed countries and in elderly populations. As such, PLC prevention schedules should give more attention to NASH and elderly patients.Funding Information
