Islami F, et al. - The most recent nationwide data for prevalence of esophageal squamous cell carcinoma, esophageal adenocarcinoma (EAC), gastric cardia adenocarcinoma (GCA), and gastric non-cardia adenocarcinoma (GNCA) by race, ethnicity, and age in the US was investigated. Using nationwide data assembled by the North American Association of Central Cancer Registries, average current prevalence rates (2010-2014) and annual percent changes in rates (from 1997 through 2014) by race, ethnicity, and age were calculated for each cancer subtype. The authors discovered increasing prevalence trends for EAC, GCA, and GNCA in several subpopulations of the US using this high-quality nationwide population-based data.
