Intrahepatic Cholangiocarcinoma (ICC) is the second most common primary liver cancer, accounting for 10% to 15% of primary hepatic malignancy, and its incidence is increasing in Western Countries.
Surgery with curative intent is the only treatment that offers a chance of long-term survival, with a reported 5-year overall survival rate ranging from 17% to 48%. In the most of recent series postoperative mortality is lower than 5% and morbidity varied from 6% to 66%. The macroscopic classification of ICC, proposed by Liver Cancer Study Group of Japan (LCSGJ), reflects different biologic behaviours, pattern of tumor growth and clinicopathological findings. The most important prognostic factors after resection are positive resection margins, lymph-node metastases, tumor size, presence of macrovascular invasion and intrahepatic metastases. Unfortunately, recurrence is still frequent and it is the leading cause of death. The treatment of the recurrence varied according to the location and extension of the disease.
Recently, expression of several genes found to be related with the carcinogenesis of ICC. These molecular findings are helpful to differentiate the biological behaviour and will provide evidence for the development of new target therapies.
