Overview
Common risk factors in the development of cholangiocarcinoma are chronic inflammatory conditions of bile duct, liver fluke infections, choledochal cysts, toxins, and viral infections.
Risk Factors
A number of risk factors for the development of cholangiocarcinoma have been described; in the Western world, the most common of these is primary sclerosing cholangitis (PSC), an inflammatory disease of the bile ducts which is in turn closely associated with ulcerative colitis (UC). Epidemiologic studies have suggested that the lifetime risk of developing cholangiocarcinoma for a person with PSC is 10%–15%,[1] although autopsy series have found rates as high as 30% in this population. The mechanism by which PSC increases the risk of cholangiocarcinoma is not well-understood. Clinical data has suggested that the development of cholangiocarcinoma is related to several factors.[2]
Chronic inflammation of the bile duct:[3]
- Primary sclerosing cholangitis (major risk factor in western countries)
- Recurrent pyogenic cholangitis (major risk factor in endemic areas)
- Ulcerative colitis
- Cholelithiasis
- Cirrhosis
Liver fluke infections: Liver fluke infection is a major cause of cholangiocarcinoma in some Asian countries.[4][5][6]
- Opisthorchis viverrini (found in Thailand, Laos, and Malaysia)
- Clonorchis sinensis (found in Japan, Korea, and Vietnam)
Choledochal cysts:
- Caroli's disease
- Thorotrast(widely used as a contrast agent for x-rays until 1950s)
- Dioxin
- Polyvinyl chloride
- Heavy alcoholism
- HIV
- Hepatitis B
- Hepatitis C
- EBV
- Lynch syndrome II
- Biliary papillomatosis
Obesity
