Jaruvongvanich V, et al. - Researchers studied the clinical characteristics and sociodemographic factors associated with the trends in population-based gallbladder cancer incidence and survival in the United States by using 2001-2012 data from 18 registries of the Surveillance, Epidemiology, and End Results database. A total of 7,769 patients were identified. Using demographic subgroup, they calculated incidence rates and Joinpoint trends. They noted stable overall incidence rates for gallbladder cancer during the 2001 to 2012 time period. Compared with white individuals, 3 and 1.6 times higher incidence rates were reported among Hispanic and black individuals, respectively. A remarkable increase in the incidence rates among black individuals and decrease among Hispanic individuals was noted over the time period. The factors that showed an independent association with shorter overall survival included male sex, older age, and single and divorced statuses, whereas higher education and higher income were related to longer survival. Furthermore, except for Hispanics and black individuals, an improvement in the overall survival was noted among all races/ethnicities.
