Incidence and Mortality
Cancer arising in the extrahepatic bile duct is an uncommon disease, and is curable by surgery in fewer than 10% of all cases.
Prognosis depends in part on the tumor's anatomic location, which affects its resectability. Total resection is possible in 25% to 30% of lesions that originate in the distal bile duct, a resectability rate that is clearly better than for lesions that occur in more proximal sites.
