clear cells intrahepatic cholangiocarcinoma

Motoko Sasaki, Yasuni Nakanuma
A subgroup of intrahepatic cholangiocarcinoma and combined hepatocellular- cholangiocarcinoma contain a component of cholangiolocellular carcinoma, which is composed of small bile ductular cells. Ductular reaction, a reactive lesion at the portal tract interface comprising increased bile ductules, is frequently seen in chronic advanced liver diseases. Bile duct adenoma, a benign tumor/tumorous lesion is also composed of bile ductular cells. Differential diagnosis among these bile ductular tumors/lesions is sometimes difficult...

Intrahepatic clear cell bile duct adenoma is extremely rare, with only 3 previous cases reported in the literature. The cause of cytoplasmic clearing in clear cell bile duct adenoma has not been previously investigated. Distinguishing clear cell bile duct adenoma from other clear cell tumors, particularly clear cell cholangiocarcinoma, can be challenging. Previous studies have shown loss of CD10 expression and focal CD56 expression in cholangiocarcinoma. Expressions of CD10 and CD56 have not been previously studied in clear cell bile duct adenoma...

This review critically discusses the most recent advances in the role of Notch signaling in liver development, homeostasis, and disease. It is now clear that the significance of Notch in determining mammalian cell fates and functions extends beyond development, and Notch is a major regular of organ homeostasis. Moreover, Notch signaling is reactivated upon injury and regulates the complex interactions between the distinct liver cell types involved in the repair process. Notch is also involved in the regulation of liver metabolism, inflammation, and cancer...

We report the case of a 57-year-old man who was diagnosed with a large unresectable cholangiocarcinoma associated with 2 satellite nodules and without clear margins with the right hepatic vein. Despite 4 cycles of GEMOX (stopped due to a hypertransaminasemia believed to be due to gemcitabine) and 4 cycles of FOLFIRINOX, the tumor remained stable and continued to be considered unresectable. Radioembolization (resin microspheres, SIRS-spheres) targeting the left liver (474 MBq) and segment IV (440 MBq) was performed...

Clear cell papillary cholangiocarcinoma is a rare variant of intrahepatic cholangiocarcinoma with only nine reported cases in the literature. This tumor needs to be differentiated from clear cell variant of hepatocellular carcinoma and other metastatic clear cell carcinomas. This tumor is known to have better prognosis compared to conventional intrahepatic cholangiocarcinoma. Hence, it is important to correctly diagnose this entity and differentiate it from other histologic mimics. We describe clinical, histopathological, and immunohistochemical findings of one such rare case in a 66-year-old gentleman who was incidentally detected to have an intrahepatic tumor at routine ultrasound examination...

The Notch signaling pathway has been reported to play crucial roles in inhibiting hepatocyte differentiation and allowing formation of intrahepatic bile ducts. However, little is known about its significance in intrahepatic cholangiocarcinoma (ICC). The aim of the present study was to investigate the effects of Notch1 expression in ICC tissues and cells. The expression of Notch1 was examined in paraffin-embedded sections of ICC (n=44) by immunohistochemistry. Notch1 was knocked down by RNA interference (RNAi) in cultured ICC cells (RBE and HCCC-9810)...

BACKGROUND/AIMS: Complete operative resection is the only approach to cure for intrahepatic cholangiocellular carcinoma (ICC), but the disease's prognosis is notably poor. A novel therapeutic approach is urgently required. CXC chemokine receptor 2 (CXCR2) has been associated with tumorigenesis and metastasis in human cancers. In this study, we investigated the suppressive effect of ICC growth by blocking CXCR2. MATERIAL AND METHODS: The role of CXCR2 was estimated using the human ICC cell lines, RBE and SSP25...

Intrahepatic cholangiocarcinoma arising in chronic advanced liver disease sometimes contains a component of cholangiolocellular carcinoma. Bile duct adenoma, a benign tumor/tumorous lesion and ductular reaction, is also composed of bile ductular cells, and the differential diagnosis is sometimes difficult. We have previously reported that cholangiolocellular carcinoma showed overexpression of a polycomb group protein EZH2, which participates in bypass/escape from cellular senescence during carcinogenesis. In contrast, the ductular reaction showed high expression of senescence-associated p16(INK4a)...

The influence of Glucagon-like peptide-1 (GLP-1) and Exendin-4 on development of intrahepatic cholangiocarcinoma (ICC) is evaluated in the study. In vitro tests, including acute toxicity test, cell colony formation assays, cells proliferation and apoptosis, transwell assay, were performed. An ICC in situ tumor animal model was established. Then, animals were randomly divided into four groups (n = 6): control, Exendin-4 treatment, oxaliplatin treatment and Exendin-4-oxaliplatin treatment. Animals in the Exendin-4 treatment and Exendin-4-oxaliplatin treatment groups received a subcutaneous injection of Exendin-4 (100 μg/kg/day) for 1 week, and then received oxaliplatin (10 mg/kg/week) by tail vein injection...

Cholangiocarcinoma (CCA) associated by Opisthorchis viverrini remains a health problem in Southeast Asia including Thailand. At present, there is still no efficient treatment for CCA. Thunbergia laurifolia is a traditionally used medicinal plant; its aqueous leave extract possesses the antioxidant activity and anti-inflammatory on hamster opisthorchiasis had been reported previously. Here, we demonstrate the combined effects of the T. laurifolia extract plus antihelminthic drug, praziquantel (PZ) on hamsters with opisthorchiasis and hamsters with opisthorchiasis related-cholangiocarcinoma through light microscopic observations of histopathological changes, as well as liver function tests for alanine transaminase (ALT) and alkaline phosphatase, and kidney function tests for blood urea nitrogen and creatinine...

BACKGROUND: How to resect the caudate lobe safely is a major challenge to current liver surgery which requires further study. METHODS: Nine cases (6 hepatic cell carcinoma, 2 cavernous hemangioma and 1 intrahepatic cholangiocacinoma) were performed using the anterior transhepatic approach in the isolated complete caudate lobe resection. During the operation, we used the following techniques: the intraoperative routine use of Peng's multifunction operative dissector (PMOD), inflow and outflow of hepatic blood control, low central venous pressure and selective use of liver hanging maneuver...

Cholangiocarcinoma (CC) arising from the large intrahepatic bile ducts and extrahepatic hilar bile ducts share clinicopathological features and have been called hilar and perihilar CC as a group. However, "hilar and perihilar CC" are also used to refer exclusively to the intrahepatic hilar type CC or, more commonly, the extrahepatic hilar CC. Grossly, a major distinction can be made between papillary and non-papillary tumors. Histologically, most hilar CCs are well to moderately differentiated conventional type (biliary) carcinomas...

Improving therapy for patients with cholangiocarcinoma (CCA) presents a significant challenge. This is made more difficult by a lack of a clear understanding of potential molecular targets, such as deregulated kinases. In this work, we profiled the activated kinases in CCA in order to apply them as the targets for CCA therapy. Human phospho-receptor tyrosine kinases (RTKs) and phospho-kinase array analyses revealed that multiple kinases are activated in both CCA cell lines and human CCA tissues that included cell growth, apoptosis, cell to cell interaction, movement, and angiogenesis RTKs...

Cholangiocarcinoma morbidity and mortality is attributable to local invasiveness and regional lymph node and distant organ metastasis. Cholangiocarcinoma progression follows a series of sequential events that resemble wound healing reactions: local invasion resembles the epithelial migration phase involving epithelial-mesenchymal transition (EMT); colonization at distant sites resembles epithelial restitution seen during the reverse process, mesenchymal-epithelial transition (MET). In this study we compare the in vivo local and metastatic growth potential of cholangiocarcinoma cell lines with respect to expression of a novel pSTAT3-dependent, biliary epithelial cell wound healing protein, small proline-rich protein 2A (SPRR2A)...

BACKGROUND: Cholangiocarcinoma is a malignant tumor arising from the epithelium of the bile ducts. In this study, we prepared sorafenib-loaded biliary stents for potential application as drug-delivery systems for localized treatment of extrahepatic cholangiocarcinoma. METHODS: A sorafenib-coated metal stent was prepared using an electrospray system with the aid of poly(ε-caprolactone) (PCL), and then its anticancer activity was investigated using human cholangiocellular carcinoma (HuCC)-T1 cells in vitro and a mouse tumor xenograft model in vivo...

The aim of this study is to show the different diagnostic procedures and treatment in patients diagnosed with congenital choledochal cysts. Choledochal cysts are congenital anomalies of the bile ducts and include cystic dilatation of the extrahepatic and intrahepatic biliary ducts or both. The study shows ten patients diagnosed as having choledochal cysts. Diagnosis was established by clinical and radiographic findings including: ultrasound (US), magnetic resonance cholangiopancreatograpy (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and cytological examination of the bile juice...

BACKGROUNDS & AIMS: Cholangiocarcinoma (CCA) is highly fatal because of early invasion, widespread metastasis, and lack of an effective therapy. Migration, invasion, and metastasis of CCA cells are modulated by signals received from stromal cells. The SDF-1-CXCR4 axis emerges as a pivotal regulator of migration and survival of different tumor cells. The aim of the present study was to characterize the interaction between CCA cells and human hepatic stellate cells (hHSC) focusing on the role of SDF-1...

Somatic mutations in isocitrate dehydrogenase 1 and 2 genes are common in gliomas and help stratify patients with brain cancer into histologic and molecular subtypes. However, these mutations are considered rare in other solid tumors. The aims of this study were to determine the frequency of isocitrate dehydrogenase 1 and 2 mutations in cholangiocarcinoma and to assess histopathologic differences between specimens with and without an isocitrate dehydrogenase mutation. We sequenced 94 formalin-fixed, paraffin-embedded cholangiocarcinoma (67 intrahepatic and 27 extrahepatic) assessing for isocitrate dehydrogenase 1 (codon 132) and isocitrate dehydrogenase 2 (codons 140 and 172) mutations...

OBJECTIVES: Hepatocellular carcinoma (HCC) and cholangiolar carcinoma (CC) cell lines are used to analyze the basic mechanisms of carcinogenesis and target therapies. However, it is not yet clear which chromosomal aberrations are to be typically expected in such cell lines. It is also not clear whether there are prerequisites for in vitro growth on the genomic and/or expression level. We therefore analyzed HCC and CC cell lines for typical genetic settings. METHODS: The HCC cell lines HLE, HLF, Huh7, HepG2 and Hep3b and the CC cell lines EGI1, MzCha1 and TFK-1 were analyzed using high-density arrays for comparative genomic hybridization (aCGH; 244,000 oligonucleotides)...
