Diagnosis and Treatment of Cholangiocarcinoma The exact cause of cholangiocarcinoma is unknown, and most cases occur sporadically, but there are several well-defined risk factors. The most common of these is primary sclerosing cholangitis (PSC). The true incidence of cholangiocarcinoma in the setting of PSC is reported as 8%-40%, depending on the type of study.

Bile Duct Cancer (Cholangiocarcinoma) Bile duct cancer arises from the cells that line the bile ducts, the drainage system for bile produced by the liver. Bile ducts collect this bile, draining it into the gallbladder and finally into the small intestine where it aids in the digestion process. Bile duct cancer is also called cholangiocarcinoma.ile duct cancer arises from the cells that line the bile ducts, the drainage system for bile produced by the liver.

Overview It's not clear what causes most cases of liver cancer. But in some cases, the cause is known. For instance, chronic infection with certain hepatitis viruses can cause liver cancer. Liver cancer occurs when liver cells develop changes (mutations) in their DNA — the material that provides instructions for every chemical process in your body. DNA mutations cause changes in these instructions.

- Extrahepatic jaundice is most often due to a stone in the common bile duct (CBD) or a pancreaticobiliary malignancy (pancreatic, ampullary or cholangiocarcinoma). The evaluation of cholestatic jaundice is a common problem in clinical practice.

What Are the Risk Factors for Bile Duct Cancer? Several conditions of the liver or bile ducts can cause this. 1  Primary sclerosing cholangitis is a condition in which inflammation of the bile ducts (cholangitis) leads to the formation of scar tissue (sclerosis). 2  People with this condition have an increased risk of bile duct cancer. Cirrhosis is damage to the liver from irritants such as alcohol and diseases such as hepatitis that cause scar tissue to form. 2  Studies have found it raises the risk of bile duct cancer. 3  Infection with hepatitis B virus or hepatitis C virus increases the risk of intrahepatic bile duct cancers.

Cholestasis (BRIC) Acute extrahepatic cholestasis is caused by obstruction to the bile ducts due to malignancy, benign bile duct stricture, bile duct compression, bile duct stones, gallstones and infectious cholangitis. Drugs, viral infections, sepsis and cholestatic conditions can lead to acute intrahepatic cholestasis.

Gallbladder and Biliary Tract Disease Mirizzi's syndrome is caused by an impacted cystic duct stone, leading to gallbladder distention and subsequent compression of the extrahepatic biliary tree. Occasionally, the gallstone erodes into the common hepatic duct, producing a cholecystocholedochal fistula.

- A more severe form of gallstone disease is cholangitis, which causes stone impaction in the common bile duct. In about 70% of cases, these patients present with Charcot's triad (pain, jaundice, and fever).

Chondrosarcoma Causes. The cause is unknown. Patients may have a history of enchondroma or osteochondroma. A small minority of secondary chondrosarcomas occur in patients with Maffucci syndrome and Ollier disease. It has been associated with faulty isocitrate dehydrogenase 1 and 2 enzymes, which are also associated with gliomas and leukemias. Diagnosis

Hepatocellular carcinoma In the Eastern Asian hemisphere, hepatocellular carcinoma (HCC) is the most common type of cancer. The common risk factor for HCC in Asia is the high diagnosis of Hepatitis B. However, in Japan the common risk factor is hepatitis C. Another factor is that causes HCC is a mycotoxin called aflatoxin.

Liver Cancer - Hepatocellular Carcinoma Hepatocellular carcinoma accounts for most liver cancers. This type of cancer occurs more often in men than women. It is usually seen in people age 50 or older. Hepatocellular carcinoma is not the same as metastatic liver cancer, which starts in another organ (such as the breast or colon) and spreads to the liver.In most cases, the cause of liver cancer is scarring of the liver (cirrhosis).Cirrhosis may be caused by: 1  Alcohol abuse. 2  Autoimmune diseases of the liver.epatocellular carcinoma is not the same as metastatic liver cancer, which starts in another organ (such as the breast or colon) and spreads to the liver.

Alcoholic Liver Disease  In-Depth Report People with cirrhosis have an increased risk for hepatocellular carcinoma, a type of liver cancer. Hepatitis B and C, alcoholism, hemochromatosis, and primary biliary cirrhosis -- all causes of cirrhosis -- are some of the major risk factors for liver cancer.Cirrhosis due to hepatitis C is the leading cause of hepatocellular carcinoma in the United States.lcoholic cirrhosis is the primary type of cirrhosis in the U.S. It develops in 10 - 20% of heavy drinkers, usually after 10 - 15 years of heavy alcohol consumption. People who drink heavily and who also have hepatitis C are at particular risk of developing cirrhosis.

Primary Biliary Cholangitis/Cirrhosis What is primary biliary cholangitis (PBC)? Primary biliary cholangitis used to be called primary biliary cirrhosis and is a type of liver disease caused by damage to the bile ducts in the liver. Much like other forms of liver disease, PBC permanently damages the liver as tissue is replaced with scar tissue (fibrosis).

Gallbladder and Biliary Tract Disease Back to TopCauses. There are many causes of cholestasis. Extrahepatic cholestasis occurs outside the liver. It can be caused by: Bile duct tumors. Cysts. Narrowing of the bile duct (strictures) Stones in the common bile duct. Pancreatitis.

What are the symptoms of pancreatic cancer? It is common for people with pancreatic cancer to experience jaundice. Jaundice is a yellowing of the skin and eyes caused by excess bilirubin (a component of bile) in the blood. A tumor in the head of the pancreas can cause narrowing of the bile duct and block the bile flowing from the gallbladder into the small intestine. Blockage of the bile duct causes a buildup of bilirubin.

What Causes Carcinoid Syndrome? When carcinoid tumors metastasize to the liver, the substances they overproduce can more easily reach your bloodstream, and reach tissues where they can cause symptoms. Serotonin breaks down into smaller parts, called metabolites. The most important serotonin metabolite is 5-HIAA (5-hydroxyindoleacetic acid).

What Causes Pancreatic Cancer? What Causes Pancreatic Cancer? Pancreatic cancer causes are not yet well understood. Through extensive research studies, scientists have determined that pancreatic cancer forms when cells within the pancreas develop mutations in their DNA, or genetic information. These mutations cause the cells to grow uncontrollably or live longer than they should.

Hepatocellular carcinoma Hepatocellular carcinoma. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer in adults, and is the most common cause of death in people with cirrhosis. It occurs in the setting of chronic liver inflammation, and is most closely linked to chronic viral hepatitis infection (hepatitis B or C) or exposure to toxins such as alcohol or aflatoxin.

Liver Cancer Hepatocellular carcinoma (HCC, also called malignant hepatoma) is the most common type of liver cancer. Most cases of HCC are secondary to either a viral hepatitis infection (hepatitis B or C) or cirrhosis (alcoholism being the most common cause of liver cirrhosis).
