Hilar cholangiocarcinoma is a rare malignant tumor arising from the epithelium of the bile ducts. Surgery is still the only chance of potentially curative treatment in patients with perihilar cholangiocarcinoma. However, radical resection requires aggressive surgical strategies that should be tailored optimally according to the location, size and vascular invasion of the tumors. Accurate diagnosis and staging of these tumors is therefore critical for optimal treatment planning and for determining a prognosis. Multidetector computed tomography (MDCT), magnetic resonance imaging (MRI) and MR cholangiography are useful tools, both to diagnose and stage hilar cholangiocarcinoma. Modern imaging techniques allow accurate detection of the level of obstruction and the longitudinal and radial spread of the tumor. In addition, high-resolution MDCT and MR provide specific radiographic features to determine vascular involvement of anatomic structures, such as the hepatic artery or the portal vein, which are critical to decide the surgical strategy. Finally, radiological staging allows detection of patients with distant metastasis in the liver or peritoneum who will not benefit from a surgical approach.

The prognostic value of lymph node (LN) assessment after liver resection for hilar cholangiocarcinoma (HC) is still controversial, and the number of LNs required to be removed to obtain adequate stagi...
The purpose of this study is to investigate the value of multidetector computed tomography (MDCT) assessment of resectability in hilar cholangiocarcinoma, and to identify the factors associated with u...
Although hemihepatectomy with total caudate lobectomy (hemiHx-tc) is essential for the surgical treatment of hilar cholangiocarcinoma, the advantage of an anterior approach for hemiHx-tc has not been ...
Cholangiocarcinoma is a rare biliary adenocarcinoma associated with poor outcomes. Cholangiocarcinoma is subdivided into extrahepatic and intrahepatic variants. Intrahepatic cholangiocarcinoma is then...
The diagnosis of cholangiocarcinoma (CCA) is difficult. The present study aimed to assess the clinical features, diagnosis, and survival in CCA.
To evaluate the feasibility and performance of coregistered 18F-FDG-PET/MRI in the staging of potentially respectable hilar cholangiocarcinoma.
To determine the safety and efficacy of photodynamic therapy with a novel photosensitizer and a flexible laser probe in locally advanced hilar cholangiocarcinoma.
The investigators conducted a prospective study to determine the safety and efficacy of minor and major hepatectomy selected by predetermined criteria in 138 patients with hilar cholangioc...
This study is to investigate whether preoperative biliary drainage can reduce the postoperative morbidity in patients with hilar cholangiocarcinoma.
The purpose of this study is to compare the quality of life in patients with unresectable hilar cholangiocarcinoma on palliative metallic stent versus plastic Stent.
Serological tumor marker composed of a molecular complex of cytokeratins 8, 18, and 19. It is used in the diagnosis and staging of bronchogenic carcinoma.
Ratio of T-LYMPHOCYTES that express the CD4 ANTIGEN to those that express the CD8 ANTIGEN. This value is commonly assessed in the diagnosis and staging of diseases affecting the IMMUNE SYSTEM including HIV INFECTIONS.
Cholangiocarcinoma arising near or at the confluence of the right and left hepatic ducts (COMMON HEPATIC DUCT). These tumors are generally small, sharply localized, and seldom metastasizing.
Methods which attempt to express in replicable terms the extent of the neoplasm in the patient.
A malignant tumor arising from the intrahepatic bile duct epithelium. It is composed of ducts lined by cuboidal or columnar cells that do not contain bile, with abundant stroma. (From Holland et al., Cancer Medicine, 3d ed, p1455; Stedman, 25th ed)
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
