Gallbladder cancer is a leading cause of cancer death among women in Chile, which has among the highest reported gallbladder cancer incidence and mortality rates in the world. Gallbladder cancer provides a particularly good model for understanding the role of inflammation in carcinogenesis since the major risk factor, gallstones, causes substantial inflammation in the gallbladder. Chile also has a high prevalence of obesity, diabetes, and metabolic syndrome, which are increasingly understood as inflammatory disorders, but the extent to which their carcinogenic effects are mediated through inflammatory pathways is unknown.
