β¦ Synopsis
Cholangiocarcinoma (CC) is the second most common primary hepatic malignancy after hepatocellular cancer. CC accounts for approximately 10%-25% of all hepatobiliary malignancies. There are considerable geographic and demographic variations in the incidence of CC. There are several established risk factors for CC, including parasitic infections, primary sclerosing cholangitis, biliary-duct cysts, hepatolithiasis, and toxins. Other less-established potential risk factors include inflammatory bowel disease, hepatitis C virus, hepatitis B virus, cirrhosis, diabetes, obesity, alcohol drinking, tobacco smoking, and host genetic polymorphisms. In studies where the distinction between intra-and extrahepatic CC was used, some potential risk factors seem to have a differential effect on CC, depending on the site. Therefore, the consistent use of a more refined classification would allow a better understanding of risk factors for CC. (HEPATOLOGY 2011;54:173-184

## Abstract Recently, the incidence of intrahepatic cholangiocarcinoma (ICC) has been increasing in a number of developed (Western) countries. However, risk factors in these lowβrisk populations are poorly understood. In this nationwide population based caseβcontrol study in Denmark, we examined th
Cholangiocarcinoma (CCA) is one of the most common cancers in north-east Thailand and has been associated with infestation by the liver fluke Opisthorchis viverrini (OV). Two samples of 12-hr overnight urine (after dosing with proline and ascorbic acid or proline alone) were collected from 20 inhabi
## ~ ~ Intrahepatic cholangiocarcinoma is a rare disease. The prognostic factors of resectable cholangiocarcinoma have not been previously reported. Nineteen patients (lOM, 9F) with resectable cholangiocarcinoma were investigated to find factors that might influence prognosis. The cumulative surv
