Biliary tract cancers are rare neoplasms including gallbladder cancer (the commonest), extrahepatic biliary tract cancer and cancer of the ampulla of Vater. Descriptive epidemiology of biliary tract cancers as a whole has two peculiarities: incidence and mortality rates are higher for women than men, and in some specific populations. Mortality rates are highest among New Mexico American Indian women, in Chile and Japan, lowest in Great Britain and Greece. Mortality trends vary widely: the largest increases have been observed in Japan, Hong-Kong and Spain and the largest decreases in the Anglo-Saxon populations. Our knowledge of biliary tract cancer etiology is limited. Defined risks include genetic factors (family history of biliary tract cancers, ethnicity), history of gallbladder disease, and cholelithiasis. Risk factors reported in some studies, on which, however, information is not consistent and which need further study, include overweight, some menstrual and reproductive factors (multiparity, young age at first birth, late menopause), low education, cigarette smoking, selected bacterial infections, some intestinal diseases and diabetes.
