INTRODUCTION: Combined hepatocellular-cholangiocarcinoma (CHC or cHCC-CC) is a rare primary liver tumor displaying histological features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA). Most patients are not suitable for surgery because of the advanced stage of the disease at the moment of diagnosis. We decided to review the literature in order to identify the outcomes after liver transplantation for CHC and to clarify which is the most appropriate treatment. MATERIAL AND METHODS: A systematic literature search was performed...

PURPOSE: The aim of this study was to evaluate the diagnostic and prognostic role of metabolic parameters of FDG PET/CT in patients with intrahepatic cholangiocarcinoma (ICC). METHODS: From December 2008 to December 2013, 76 FDG PET/CT scans performed for initial staging of ICC in a single institution (57 male and 19 female; mean age 68 ± 9 years) were retrospectively reviewed. Patients with history of other known malignancy were excluded. Detection rates of regional lymph node and distant metastasis by FDG PET/CT were analyzed in comparison with conventional imaging modalities such as CT or MRI...

Cholangiocarcinoma (CC) is the second most common primary hepatobiliary tumour, and it is increasing in incidence. Imaging characteristics, behaviour, and therapeutic strategies in CC differ significantly, depending on the morphology and location of the tumour. In cross-sectional imaging, CCs can be classified according to the growth pattern (mass-forming, periductal infiltrating, intraductal) and the location (intrahepatic, perihilar, extrahepatic/distal). The prognosis of CC is unfavourable and surgical resection is the only curative treatment option; thus, early diagnosis (also in recurrent disease) and accurate staging including the evaluation of lymph node involvement and vascular infiltration is crucial...

A 76-year-old man underwent radical surgery for Stage IV a hilar cholangiocarcinoma in July 2009, and had been followed at an outpatient clinic. Although no apparent recurrent lesion was detected by PET/CT examination, an elevated CA19-9 level was found in January 2014. He was then started on the oral anticancer drug S-1. However, his CA19-9 level increased gradually. The patient presented to a urological department with a complaint of macrohematuria in May 2015. Detailed examination revealed a mass lesion at the top of the urinary bladder, which was suspected to be peritoneal dissemination of the known hilar cholangiocarcinoma invading the urinary bladder wall...

Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center...

PURPOSE: [(18)F]fluorocholine PET/CT can detect hepatocellular carcinoma (HCC) based on imaging the initial steps of phosphatidylcholine synthesis. To relate the diagnostic performance of [(18)F]fluorocholine positron emission tomography (PET)/x-ray computed tomography (CT) to the phospholipid composition of liver tumors, radiopathologic correspondence was performed in patients with early-stage liver cancer who had undergone [(18)F]fluorocholine PET/CT before tumor resection. PROCEDURES: Tumor and adjacent liver were profiled by liquid chromatography mass spectrometry, quantifying phosphatidylcholine species by mass-to-charge ratio...

The current National Comprehensive Cancer Network (NCCN) Guidelines consider the role of 2-deoxy-2-(18)F-fluoro-d-glucose positron emission tomography/computer tomography (FDG PET/CT) in the evaluation of cholangiocarcinoma (CCA) as "uncertain," and have recommended contrast enhanced computed tomography (CECT) but not FDG PET/CT as a routine imaging test for CCA workup. We set out to compare the diagnostic performance of FDG PET/CT and CECT in patients with CCA. The retrospective study included patients with CCA who underwent FDG PET/CT and CECT within 2-month interval between 2011 and 2013 in our hospital...

PET/computed tomography (PET/CT) is an established hybrid imaging technique for staging and follow-up of gastrointestinal (GI) tract malignancies, especially for colorectal carcinoma. Dedicated hybrid PET/MR imaging scanners are currently available for clinical use. Although they will not replace regular use of PET/CT, they may have utility in selected cases of GI tract malignancies. The superior soft tissue contrast resolution and depiction of anatomy and the functional information obtained from diffusion-weighted imaging (DWI) provided by MR imaging in PET/MR imaging are advantages over CT of PET/CT for T staging and follow-up of rectal carcinoma and for better characterization of liver lesions...

Cholangiocarcinoma (bile ducts cancer) is a rare and aggressive form of cancer. It metastasizes frequently to liver, peritoneum, and lungs. Colon metastasis is extremely uncommon. We report here a 70-year-old male who was diagnosed with cholangiocarcinoma for which he underwent a Whipple procedure. Fifteen months later, a CT scan revealed mural thickening in the colon; this was supplemented with a PET scan, which confirmed this mass. Histological diagnosis of metastatic cholangiocarcinoma to the colon was made and the patient was treated with chemotherapy...

BACKGROUND: Limbic encephalitis was originally described as a rare clinical neuropathological entity involving seizures and neuropsychological disturbances. In this report, we describe cerebral patterns visualized by positron emission tomography in a patient with limbic encephalitis and cholangiocarcinoma. To our knowledge, there is no other description in the literature of cerebral positron emission tomography findings in the setting of limbic encephalitis and subsequent diagnosis of cholangiocarcinoma...

PET using fluorine-18 fluorocholine ((18)F-fluorocholine) may detect malignancies that involve altered choline metabolism. While (18)F-fluorocholine PET/CT has shown greater sensitivity for detecting hepatocellular carcinoma (HCC) than (18)F-fluoro-D-deoxyglucose (FDG) PET/CT, it is not known whether it can also detect intrahepatic cholangiocarcinoma (ICC), a less common form of primary liver cancer. Clinical, radiographic, and histopathologic data from 5 patients with ICC and 23 patients with HCC from a diagnostic trial of liver (18)F-fluorocholine PET/CT imaging were analyzed to preliminarily evaluate (18)F-fluorocholine PET/CT for ICC...

Cholangiocarcinoma, a tumor of biliary epithelium, is increasing in incidence. The imaging appearance, behavior, and treatment of cholangiocarcinoma differ according to its location and morphology. Cholangiocarcinoma is usually classified as intrahepatic, perihilar, or distal. The three morphologies are mass-forming, periductal sclerosing, and intraductal growing. As surgical resection is the only cure, prompt diagnosis and accurate staging is crucial. In staging, vascular involvement, longitudinal spread, and lymphadenopathy are important to assess...

A 46-year-old woman underwent right hemihepatectomy, cholecystectomy, and sampling of the hilar lymph nodes for combined hepatocellular and cholangiocarcinoma. She received oral S-1 after hepatectomy. However, her serum level of carcinoembryonic antigen gradually increased, and solitary paraaortic lymph node recurrence was detected on positron emission tomography-computed tomography 12 months after hepatectomy. The patient underwent paraaortic lymph node dissection. Histologic examination revealed solitary paraaortic lymph node metastasis composed of hepatocellular carcinoma...

Hilar cholangiocarcinoma (HCC) remains one of the most difficult tumors to stage and treat. The aim of the study was to assess the diagnostic efficiency of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computer tomography (PET/CT) in evaluating the resectability of HCC. A systematic search was performed of the PubMed, EMBASE, and Cochrane databases. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated for individual studies and pooled data as well as test for heterogeneity and public bias...

Opisthorchis viverrini (OV)-induced cholangiocarcinoma (CCA) is an important cancer in the Great Mekong region, particularly in Thailand. Limitations of treatment options and the lack of an effective diagnostic tool for early detection of CCA are major concerns for the control of this type of cancer. The aim of the study was to investigate anti-CCA activity of the ethanolic extract of Atractylodes lancea (Thunb.) DC., and the applicability of positron emission tomography-computed tomography (PET-CT) as a tool for detection and monitoring the progression of CCA in Opisthorchis viverrini (OV)/dimethylnitrosamine (DMN)-induced CCA hamsters...

An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists met on 15 January 2014 to review current evidence on the management of intrahepatic cholangiocarcinoma (ICC) in order to establish practice guidelines and to agree on consensus statements. The treatment of ICC requires a coordinated, multidisciplinary approach to optimize survival. Biopsy is not necessary if the surgeon suspects ICC and is planning curative resection, although biopsy should be obtained before systemic or locoregional therapies are initiated...

The gallbladder neck cancer and perihilar cholangiocarcinoma present as painless progressive surgical obstructive jaundice. Sometimes it becomes difficult to differentiate between them even on cross-sectional imaging studies including computed tomography and magnetic resonance imaging. Staging laparoscopy and positron emission tomography may be useful in detecting metastases in gallbladder neck cancer, but are not recommended in perihilar cholangiocarcinoma. Most patients with gallbladder neck cancer and perihilar cholangiocarcinoma require preoperative biliary drainage...

Metastatic carcinoma that causes appendicitis is extremely rare. To our knowledge, metastatic cholangiocarcinoma in the appendix has been reported in only 1 case in the English literature. We report herein the case of an 87-year-old woman who presented with abdominal pain and jaundice. Advanced cholangiocellular carcinoma and a proximal appendiceal mass with appendicitis were detected on contrast-enhanced computed tomography and positron emission tomography/computed tomography. After elective laparoscopic appendectomy and wedge resection of the cecum, pathologic results revealed metastatic adenocarcinoma from extrahepatic cholangiocellular carcinoma in the appendix...
