Gallbladder cancer rates have been stable or declining for most Americans over the last two decades, but cases have steadily risen among Blacks, with growing numbers not being diagnosed until later stages, according to a study scheduled for presentation at Digestive Disease Week (DDW) 2024. Researchers analyzed records for 76,873 patients diagnosed with gallbladder cancer from 2001 to 2020 in the U.S. Cancer Statistics database and found gallbladder cancer incidence rates were stable among whites and declined at an average annual rate of .64% among Hispanics, while rates rose 1.03% per year among non-Hispanic Blacks. The incidence of late-stage tumors among Blacks increased at an average annual rate of 2.7%.
