Expand Collapse Gall Bladder and Bile Duct Cancers  - General Description Gallbladder cancer and bile duct cancer arise in specific areas of the biliary tract. As a group, they are fairly rare, accounting for only 3% of gastrointestinal malignancies. Standard therapy involving surgery and/or chemotherapy can be effective if the disease is detected early. However, recurrent or advanced disease has been challenging to treat.

There have been significant advances in our understanding of the underlying mechanisms of cancer development in biliary tract cancers, particularly those arising in the bile duct. Cholangiocarcinoma is the more common name for bile duct cancer and can occur either inside the liver (intrahepatic cholangiocarcinoma) or in the part of the bile duct that lies outside the liver (extrahapatic cholangiocarcinoma). The incidence of cholangiocarcinoma is rising worldwide, possibly due to an increasing incidence of hepatitis B and hepatitis C infection that can cause cirrhosis of the liver.

Ongoing research has identified new potential directions for targeted therapy in cholangiocarcinoma. Researchers at the MGH discovered a subset of patients with intrahepatic cholangiocarcinoma that have a mutation in a gene called IDH (isocitrate dehydrogenase). This mutation alters the normal activity of the enzyme encoded by this gene, with the resulting production of a new metabolite (2-hydroxyglutarate, or 2-HG). This 2-HG metabolite accumulates to very high levels in the tumor cells and alters how the tumor cell reads a subset of important genes in the DNA (epigenetic regulation). Furthermore, in a different subset of cholangiocarcinoma patients, a chromosomal abnormality in the gene FGFR2 has been identified. This abnormality is a fusion between part of the FGFR2 gene to part of another gene. The result is a cancer protein that constantly activates oncogenic FGFR2 signaling. The clinical utility of therapeutically targeting these tumor alterations are topics of current clinical trial investigations.
