Chemoradiation treatment with gemcitabine plus stereotactic body radiotherapy for unresectable, non-metastatic, locally advanced hilar cholangiocarcinoma.
Chemoradiation in patients with unresectable extrahepatic and hilar cholangiocarcinoma or at high risk for disease recurrence after resection: Another preoperative classification used in the USA is the one published by Jarnagin et al.
Its concentration in these patients varies widely and does not correlate with tumour size, although it does correlate with metastatic involvement. These authors argue that the ducts draining the caudate lobe entered directly into the bifurcation and are frequently involved with Klatskin tumors. Klxtskin of the tumor markers carbohydrate antigen CAcarcinoembryonic antigen CEA and CA are abnormally high in the bloodstreams of patients with intrahepatic cholangiocarcinoma and Klatskin tumor.
At present, there is no effective nonsurgical therapy for cholangiocarcinoma, as either an adjuvant therapy or for unresectable disease. Chronic biliary tract parasitic infection, seen ilatskin in Southeast Asia due to Clonorchis sinensis and Opisthorchis viverrini, has also been identified as a cancee factor. More recently, the routine use of staging laparoscopy prior to laparotomy has been suggested in order to minimally invasively assess patients for evidence of liver metastases or peritoneal implants.

CiteScore measures average citations received per document published.
Abdominal computerised axial tomography: It is also important to underline recent studies which show an increase in the survival of patients with preoperative vascular involvement following portal resection. They even achieve rates of survival that are equal to or higher than those for patients without preoperative vascular involvement and who were therefore not subjected to portal resection.
