Ga-PSMA PET is a rapidly evolving imaging modality for whole-body staging of prostate cancer. We report a case of a 70-year-old man with mildly elevated prostate-specific antigen (8.1 μg/L) and clinical suspicion of prostate cancer (osteoblastic metastases on radionuclide bone scan) who was referred for Ga-PSMA PET/CT for primary staging. Multiple Ga-PSMA-avid skeletal foci, mostly associated with lytic changes on low-dose CT, as well as hepatic foci of avid Ga-PSMA uptake, were identified. No abnormal focus of avid Ga-PSMA uptake was identified in the prostate...

Boron neutron capture therapy (BNCT) is a binary therapy that employs neutron irradiation on the boron agents to release high-energy helium and alpha particles to kill cancer cells. An optimal response to BNCT depends critically on the time point of maximal (10)B accumulation and highest tumor to normal ratio (T/N) for performing the neutron irradiation. The aggressive cholangiocarcinoma (CCA) representing a liver cancer that overexpresses COX-2 enzyme is aimed to be targeted by COX-2 selective boron carrier, fenbufen boronopinacol (FBPin)...

PURPOSE: Metabolism and water diffusion may have a relationship or an effect on each other in the same tumor. Knowledge of their relationship could expand the understanding of tumor biology and serve the field of oncologic imaging. This study aimed to evaluate the relationship between metabolism and water diffusivity in hepatic tumors using a simultaneous positron emission tomography/magnetic resonance imaging (PET/MRI) system with F-18 fluorodeoxyglucose (FDG) and to reveal the metabolic and diffusional characteristics of each type of hepatic tumor...

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas. Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET)...

Stereotactic body radiotherapy (SBRT) has developed over the last few years for the treatment of primary and metastatic hepatic tumors. The tumoral and adjacent peritumoral modifications caused by this radiosurgery limit the evaluation of response by anatomic imaging and dimensional criteria alone, such as with RECIST. This suggests that it is of interest to also take into account the residual enhancement and hyper metabolism of these hepatic targets. We have reviewed the English language literature regarding the response of hepatic lesions treated by SBRT, and found that only seven articles were specifically concerned with this problem...

Since the prognosis of advanced cholangiocarcinoma (CCA) remains poor with traditional chemotherapy, attention has shifted to molecularly targeted agents. Results of available clinical studies reveal little or no benefit of using targeted agents in advanced CCA. Limitations of these trials could be the lack of comprehensive molecular and genetic characterization of CCA samples in order to identify potential drug targets. Here we report a case of a 59-year-old female with chemotherapy-refractor, metastatic extrahepatic cholangiocarcinoma (EHCCA)...

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...

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...

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...

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...
