INTRODUCTION: Recent trends in the incidence and mortality of biliary tract cancers are unknown. We estimated the trends in biliary tract cancers-related incidence and mortality stratified by anatomical site, age, sex, and race/ethnicity in the US adults.
METHODS: We performed a population-based trend analysis using the US national incidence (2009-2017) and mortality records (2009-2018). We identified age-standardized incidence and mortality from intrahepatic cholangiocarcinoma (ICC), extrahepatic cholangiocarcinoma, gallbladder cancer, and ampulla of Vater cancer using appropriate ICD-10 code. Temporal mortality was calculated by joinpoint trend analysis with estimates of annual percentage change (APC) described as each trend segment.
RESULTS: The incidence rates of ICC increased linearly (APC 8.9%, 95% confidence interval [CI] 7.8%-10.0%) while gallbladder cancer-related incidence rates remained stable early and decreased significantly later in the study (APC -2.8%, 95% CI -5.5% to -0.0% [2014-2017]). Age-standardized mortality from biliary tract cancers steadily increased with an annual increase of 2.0% (95% CI 1.6%-2.3%). Although there was a linear increase in the ICC-related mortality (APC 3.5%, 95% CI 3.1%-3.8%), extrahepatic cholangiocarcinoma-related mortality tended to remain stable earlier and increased later (APC 7.0%, 95% CI 4.6%-9.5% [2013-2018]). By contrast, gallbladder cancer-related mortality steadily decreased over 10 years (APC -1.6%, 95% CI -2.1% to -1.1%). Significant differences in mortality and changes in trends over time were observed in non-Hispanic blacks, Hispanics, and non-Hispanic Asians.
DISCUSSION: In this analysis of nationally representative data, changing mortality trends in various biliary tract cancers was noted with a disproportionately higher burden of fatality in minorities.
