Objective: To investigate the incidence of primary gallbladder and biliary tract cancer, mortality and disability-adjusted life years (DALY) of the global burden from 1990 to 2017.
Methods: Data of 195 countries and territories from 1990 to 2017 were extracted from the Global Health Data Exchange. The age-standardized incidence rate (ASIR) and estimated annual percentage change (EAPC) were employed to quantify trends in the incidence of primary gallbladder and biliary tract cancer. The age-standardized death rate (ASDR), age-standardized DALY and their corresponding EAPC were used to evaluate mortality trends.
Results: The global incidence of primary gallbladder and biliary tract cancer rose by 75.9% from 119 900 cases in 1990 to 210 900 cases in 2017. The highest ASIR was observed in Chile (10.8 per 100 000 in 2017), followed by Japan and South Korea. Regions with the highest social development index (SDI) quintile also had the highest death cases associated with primary gallbladder and biliary tract cancer in 2017 (60 100, 95% UI 55 800-62 700). A high body mass index (BMI) was found to be closely related to age-standardized deaths and age-standardized DALY in most of the regions analyzed.
Conclusions: Primary gallbladder and biliary tract cancer remains a serious threat to global public health, especially in high-SDI countries. The ASDR and age-standardized DALY decreased from 1990 to 2017. A high BMI may be associated with this cancer burden.
