BACKGROUND: Intrahepatic sarcomatoid chonalgiocarcinoma (s-CCC) is an extremely rare disease, accounting for less than 1% of hepatobiliary system malignancies, and its pathophysiology is not well known. On the hypothesis that its clinical, serologic, or radiologic diagnosis are not fully understood and its prognosis is poor, we investigated the distinguishing features of s-CCC compared with those of intrahepatic bile duct adenocarcinoma [cholangiocellular carcinoma (CCC)] in patients from a single center...

A 67-year-old man with a history of left upper lobe resection of poorly differentiated adenocarcinoma 1 year ago underwent FDG PET/CT for restaging. The images demonstrated a round cystic lesion with peripheral FDG uptake and centrally photopenic region. Additional focus of increased activity was detected in the left lobe of the liver. The patient underwent the Whipple and partial hepatectomy. The surgical pathology demonstrated concurrently the metastasis to the pancreas from the lung adenocarcinoma and a primary moderately differentiated cholangiocarcinoma...

BACKGROUND: Patient-derived xenografts (PDX) are clinically relevant human cancer models that can be used to guide individualized medicine. We aimed to generate PDX models from clinically obtained biopsy specimens (surgical or image-guided) hypothesizing that low volume biopsy specimens could provide sufficient viable tissue to successfully engraft PDX models from patients with unresectable or metastatic disease. MATERIALS AND METHODS: We maintain a prospective high volume gastrointestinal malignancy PDX program...

BACKGROUND: The aim was to compare the prognostic accuracy of cross-sectional imaging of the 7th and 8th editions of the American Joint Committee on Cancer(AJCC) staging system for perihilar cholangiocarcinoma(PHC). METHODS: All patients with PHC between 2002 and 2014 were included. Imaging at the time of presentation was reassessed and clinical tumor-node-metastasis (cTNM) stage was determined according to the 7th and 8th editions of the AJCC staging system. Comparison of the prognostic accuracy was performed using the concordance index (c-index)...

Zachary P Fricker, David R Lichtenstein
Primary sclerosing cholangitis is a rare, chronic cholestatic liver disease characterized by progressive idiopathic stricturing of the biliary system, typically leading to cirrhosis, end-stage liver disease, and colonic or hepatobiliary malignancy. Its presentation is often that of asymptomatic alkaline phosphatase elevation. When symptoms are present, they typically include fatigue, pruritus, or jaundice. The diagnosis can be confirmed via cholangiography, either magnetic resonance cholangiography (MRCP) or endoscopic retrograde cholangiography if the former is inconclusive...

Intraluminal pathologic conditions of the bile ducts and gallbladder are common, most frequently consisting of calculi and adenocarcinoma. In recent years, intraductal papillary neoplasm of the bile ducts (IPN-B), which is analogous to intraductal papillary mucinous neoplasm of the pancreas, has been recognized as a distinct pathologic entity and a precursor lesion to adenocarcinoma of the bile ducts. Intraductal tubulopapillary neoplasm (ITPN) of the bile duct was subsequently described as a distinct pathologic entity...

Purpose: Daily magnetic resonance (MR)-guided radiation has the potential to improve stereotactic body radiation therapy (SBRT) for tumors of the liver. Magnetic resonance imaging (MRI) introduces unique variables that are untested clinically: electron return effect, MRI geometric distortion, MRI to radiation therapy isocenter uncertainty, multileaf collimator position error, and uncertainties with voxel size and tracking. All could lead to increased toxicity and/or local recurrences with SBRT...

Due to the need for improvement in the diagnosis and minimally invasive therapy of the bile duct disorders new technologies for cholangioscopy have been recently developed. Per-oral cholangioscopy has become an important diagnostic and therapeutic tool leading to avoidance of aggressive and unnecessary surgery in many clinical scenarios. This paper focuses on the newly developed SpyGlass DS technology, its advantages, and the technique of single-operator cholangioscopy (SOC), biliary indications and possible adverse events...

AIM: To identify magnetic resonance imaging (MRI) features for differentiating hepatocellular carcinoma (HCC) from intrahepatic cholangiocarcinoma (IHCC) and summarise their diagnostic accuracy. MATERIALS AND METHODS: PubMed and EMBASE were searched for studies that employed MRI features to differentiate HCC from IHCC. Overlapping descriptors used to denote the same imaging finding in different studies were subsumed under a single feature. The pooled diagnostic accuracies, including the diagnostic odds ratios (DORs) and 95% confidence intervals (CIs) of the identified features, were calculated using a bivariate random-effects model...

A 74-year-old man was admitted to a local hospital with liver dysfunction. Imaging modalities revealed bile duct stenosis at the bifurcation of the anterior and posterior trunk. Exfoliative cytology of the bile and brushing cytology of the bile duct both revealed Class Ⅴ, and biopsy from the stenotic bile duct showed well differentiated adenocarcinoma. We diagnosed the patient with hilar cholangiocarcinoma and performed extended right bisectionectomy and biliary reconstruction after percuta- neous transhepatic right portal vein embolization(PTPE)...

Sixty-four-year-old female who underwent hemi-hepatectomy for intrahepatic cholangiocarcinoma a year ago presented with biliary sputum, cough and fever. Cross-sectional imaging showed a recurred tumor involving right diaphragmatic area and an abscess formation in liver dome with adjacent right lower lobe of lung. Percutaneous transhepatic biliary drainage and percutaneous drainage of lung abscess were performed. Tubogram showed connections between the lung abscess cavity and multiple distal bronchi, suggesting bronchobiliary fistulas...

Radiotherapy (RT) is a treatment option for advanced biliary tract cancer (BTC), often combined with sequential and/or concurrent chemotherapy. The use of modern RT techniques requires accurate clinical target volume (CTV) definition and delineation. However, guidelines for CTV delineation in BTC are lacking. Therefore, the aim of this study was to propose a computer tomography (CT) atlas for CTV definition of BTC. We previously proposed guidelines to define the nodal CTV (CTV-N) in BTC. In this study, based on a literature analysis, we defined the margins to be added to the gross tumor volume (GTV; subclinical and microscopic disease) to define the primary tumor CTV (CTV-T)...

The present study reports a case of mass-forming intrahepatic cholangiocarcinoma (ICC), which mimicked cholangiocellular carcinoma (CoCC) during imaging and a needle biopsy examination. A 51-year-old female with no relevant medical history was referred to the National Defense Medical College hospital with an intrahepatic tumor. Computed tomography demonstrated non-homogeneous enhancement in the early arterial phase and persistent enhancement in the portal and equilibrium phases, together with notable swelling of the para-aortic lymph nodes...

Obstructive jaundice in the setting of a hilar mass raises strong suspicion of a cholangiocarcinoma, with diagnosis usually made on imaging. Jaundice, when present in patients with hepatocellular carcinoma, is mostly related to underlying liver disease (i.e. cirrhosis) and only rarely to diffuse tumor infiltration of liver parenchyma or hilar invasion. We report here the good outcome of a 67 year-old patient who presented with obstructive jaundice, underwent surgery and was given a diagnosis of hepatocellular carcinoma, which was made only at histopathological examination of resected specimen...
