Lobar decrease in 99mTc-GSA accumulation in hilar cholangiocarcinoma. (1/1066)

Hilar cholangiocarcinoma can obstruct hepatic ducts and involve the portal veins. Both biliary stasis and decrease in portal venous flow are known to reduce 99mTc-diethylenetriamine pentaacetic acid-galactosyl human serum albumin (GSA) accumulation. The specific relationship between these pathological conditions due to hilar cholangiocarcinomas and 99mTc-GSA accumulation has never been clarified. METHODS: Sixteen patients with hilar cholangiocarcinomas who underwent 99mTc-GSA liver scintigraphy were reviewed. The relationship between significant decrease in 99mTc-GSA accumulation and lobar biliary stasis, or decrease in the portal venous flow, was evaluated. Average counts of region of interest placed in both right and left lobes were compared in the same transaxial SPECT section. Count ratios of right and left lobes were calculated. RESULTS: Significant lobar decrease in 99mTc-GSA accumulation was observed in 6 of the 16 patients. Ipsilateral portal venous stenosis or obstruction was seen in all these 6 patients, whereas ipsilateral portal venous stenosis or obstruction was seen in only 1 of the other 10 patients. Symmetric bile duct dilatation was seen in 13 patients, and asymmetric bile duct dilatation was seen in 3. Lobar decrease in 99mTc-GSA accumulation correlated well with decrease in ipsilateral portal venous flow (P < 0.0005). The count ratio was significantly reduced when unilateral portal venous flow decreased (P < 0.05). CONCLUSION: Using 99mTc-GSA liver scintigraphy, we can predict lobar decrease in ipsilateral portal venous flow and monitor hepatic functional lateralities in patients with hilar cholangiocarcinomas.  (+info)

ANIT-induced disruption of biliary function in rat hepatocyte couplets. (2/1066)

alpha-Naphthylisothiocyanate (ANIT) induces intrahepatic cholestasis in rats, involving damage to biliary epithelial cells; our study aims to investigate whether disruption of biliary function in hepatocytes can contribute to early stages of ANIT-induced intrahepatic cholestasis. Isolated rat hepatocyte couplets were used to investigate biliary function in vitro by canalicular vacuolar accumulation (cVA) of a fluorescent bile acid analogue, cholyl-lysyl-fluorescein (CLF), within the canalicular vacuole between the two cells. After a 2-h exposure to ANIT, there was a concentration-dependent inhibition of cVA (cVA-IC50; 25 microM), but no cytotoxicity (LDH leakage or [ATP] decline) within this ANIT concentration range. There was no loss of cellular [GSH] at low ANIT concentrations, but, at 50 microM ANIT, a small but significant loss of [GSH] had occurred. Diethylmaleate (DEM) partially depleted cellular [GSH], but addition of 10 microM ANIT had no further effect on GSH depletion. Reduction in cVA was seen in DEM-treated cells; addition of ANIT to these cells reduced cVA further, but the magnitude of this further reduction was no greater than that caused by ANIT alone, indicating that glutathione depletion does not enhance the effect of ANIT. F-actin distribution (by phalloidin-FITC staining) showed an increased frequency of morphological change in the canalicular vacuoles but only a small, non-significant (0.05 < p < 0.1) increase in proportion of the F-actin in the region of the pericanalicular web. The results are in accord with a disruption of hepatocyte canalicular secretion within two h in vitro, at low, non-cytotoxic concentrations of ANIT, and the possible involvement of a thiocabamoyl-GSH conjugate of ANIT (GS-ANIT) in this effect.  (+info)

Lymph node metastasis in intrahepatic cholangiocarcinoma. (3/1066)

BACKGROUND: Lymph node metastasis is a significant prognostic factor in intrahepatic cholangiocarcinoma. This study was aimed at investigating lymph node metastasis in intrahepatic cholangiocarcinoma and to examine whether the extent of metastasis affects outcomes after surgery. METHODS: From 1980 through 1996, 70 patients with intrahepatic cholangiocarcinoma underwent hepatectomy, with a 50% curative resection rate. Lymph node dissection was performed in 51 patients, and the presence of lymph node metastasis was examined microscopically. The metastatic nodes were divided into groups N1, N2 or N3 using the classification proposed by the Liver Cancer Study Group of Japan. RESULTS: Twenty-three patients had lymph node metastasis. Metastasis was to N1 nodes in 10 patients, to N2 nodes in nine patients and to N3 nodes in four patients. Nineteen patients had metastatic nodes in the hepatoduodenal ligament, which was the most common metastatic site regardless of tumor location. The five-year survival rate in patients with lymph node metastasis (0%) was significantly lower (p < 0.0001) than that in patients without lymph node metastasis (51 %); however, five-year survival rates did not differ between patients with metastases to N1, N2 and N3 nodes. CONCLUSIONS: Lymph nodes in the hepatoduodenal ligament may be sentinel nodes for intrahepatic cholangiocarcinoma, and outcomes after surgery for patients with lymph node metastasis are poor regardless of the sites of nodal metastasis.  (+info)

Promoting effects of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone on rat glandular stomach carcinogenesis initiated with N-methyl-N'-nitro-N-nitrosoguanidine. (4/1066)

The modifying effects of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a mutagenic by-product in chlorinated water, on the development of glandular stomach cancers were investigated in Wistar rats. A total of 120 males, 6 weeks of age, were divided into six groups. After initiation with 100 ppm N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) solution and 5% NaCl diet for 8 weeks, 30 rats each in groups 1-3 were given MX in the drinking water at concentrations of 30, 10, or 0 ppm for the following 57 weeks. Ten animals each in groups 4-6 were administered the MX without prior carcinogen exposure. There were no statistical significant differences in final body weights between the groups. The incidences and multiplicities of adenocarcinomas in the glandular stomachs were significantly higher (P < 0.05) in the initiated 30 ppm MX group than those in the MNNG/NaCl group. The incidences of atypical hyperplasias in the glandular stomachs were also significantly increased (P < 0.05 or 0.01) by the MX treatments. With their multiplicity, the effects were clearly dose dependent. Interestingly, the 30 ppm MX alone itself induced atypical hyperplasias in the pylorus, although the incidences and severity were low. Moreover, MX showed a tendency to enhance the development of intrahepatic cholangiocellular tumors and thyroid follicular cell tumors in the MNNG-treated animals. The results of the present study thus indicate that MX exerts promoting effects when given during the postinitiation phase of two-stage glandular stomach carcinogenesis in rats.  (+info)

Acute carbon tetrachloride feeding induces damage of large but not small cholangiocytes from BDL rat liver. (5/1066)

Bile duct damage and/or loss is limited to a range of duct sizes in cholangiopathies. We tested the hypothesis that CCl4 damages only large ducts. CCl4 or mineral oil was given to bile duct-ligated (BDL) rats, and 1, 2, and 7 days later small and large cholangiocytes were purified and evaluated for apoptosis, proliferation, and secretion. In situ, we measured apoptosis by morphometric and TUNEL analysis and the number of small and large ducts by morphometry. Two days after CCl4 administration, we found an increased number of small ducts and reduced number of large ducts. In vitro apoptosis was observed only in large cholangiocytes, and this was accompanied by loss of proliferation and secretion in large cholangiocytes and loss of choleretic effect of secretin. Small cholangiocytes de novo express the secretin receptor gene and secretin-induced cAMP response. Consistent with damage of large ducts, we detected cytochrome P-4502E1 (which CCl4 converts to its radicals) only in large cholangiocytes. CCl4 induces selective apoptosis of large ducts associated with loss of large cholangiocyte proliferation and secretion.  (+info)

Expression of p73, a novel protein related to the p53 tumour suppressor p53, and apoptosis in cholangiocellular carcinoma of the liver. (6/1066)

p73, the first homologue of the tumour suppressor protein p53, was recently discovered on chromosome 1p36 and has been shown to induce apoptosis in a p53-like manner. The present study was performed with the aim of investigating the expression of p53, its new homologue p73 and the occurrence of apoptosis in cholangiocellular carcinoma. Protein levels of p73 were examined in 41 patients with curatively (R0-) resected cholangiocellular carcinomas with an antiserum, raised against a peptide in the N-terminal domain of p73. The incidence of mutations in the p53 gene was analysed by direct sequencing and also immunohistochemically. Apoptotic cell death was assessed using in-situ end-labelling (ISEL) technique in combination with morphological criteria. The results obtained were correlated with patient survival. Immunostaining of p73 protein was detected in 17/41 carcinomas examined (41%). The immunoreactivity was confined to the cell nucleus. In 15/41 patients (37%), mutations of the p53 gene were observed. Eleven out of these 15 patients stained also positive for p73. In contrast, out of 26 patients without any detectable p53 mutation, only six exhibited p73 immunostaining. We failed to observe a correlation between p73 expression or p53 and apoptosis within a given tumour. Survival analysis including the parameters stage and grade of disease, p73 and p53, and also apoptosis, showed that tumour stage and grade as well as p53 and p73 were significantly related to prognosis. In Cox regression survival analysis, however, only extent of primary tumour and lymph node status had an independent prognostic impact. Our results with a high prevalence of p73 within tumours harbouring mutated p53 gene suggest that p73 could compensate for p53 function. We failed to establish p73 or p53 as independent prognostic factors in cholangiocellular carcinoma of the liver.  (+info)

Intrahepatic peripheral cholangiocarcinoma: CT features in 18 pathologically proven cases. (7/1066)

OBJECTIVE: To determine the morphological features of 18 pathologically proven intrahepatic peripheral cholangiocarcinoma (IHPCC) cases in computerized tomography (CT) image. METHODS: All 18 patients had CT, using Picker I.Q.T/C and taking pre-contrast continuous 10-mm sections throughout the liver and post-contrast continuous 10-mm sections throughout the focuses. RESULTS: The disease was characterized in CT image by the following: all focuses were found in the periphery of the liver and shown as a lobulated or fused hypodense space-occupying mass; there were one or more divergent or confluent, circular or irregular cystic areas with much lower density, in the majority. All focuses could be enhanced slightly and most revealed a dim edge. Dilated bile ducts around the focus were found frequently; the dilated bile ducts especially seemed to encircle the focus (33.3%, 6/18). This phenomenon were referred to as "encysted sign of dilated bile ducts". CONCLUSIONS: CT scanning should be one of the most important investigative methods for IHPCC due to the disease characteristics identified in CT image, especially "encysted sign of dilated bile ducts" which possesses specificity in diagnosing the disease.  (+info)

Long-lasting sonographic and histopathological findings in cured clonorchiasis of rabbits. (8/1066)

To ascertain residual sonographic and histopathological findings of clonorchiasis after treatment, the present study evaluated sonographic findings in rabbits which were infected with 500 metacercariae of C. sinensis every 6 months for 18 months after treatment with praziquantel. The sonographic findings were analyzed in terms of intrahepatic bile duct dilatation and periductal echogenicity, and histopathological findings were observed after the last sonographic examination. Compared with the sonographic findings before treatment, dilatation of the intrahepatic bile ducts became mild to some degree in four of the seven cases and increased periductal echogenicity resolved in four of them. The histopathological specimens after 18 months showed that periductal inflammation has almost resolved but moderate dilatation of the intrahepatic ducts and mucosal hyperplasia persisted. The periductal fibrosis minimally resolved. The long-lasting sonographic findings in cured clonorchiasis make sonography less specific.  (+info)

PY - 1995/1/1. Y1 - 1995/1/1. N2 - Primitive biliary cells are known to migrate from the ductal plate into the mesenchyme during human intrahepatic bile duct development, and this migration process is essential for normal development of intrahepatic bile ducts. However, its molecular mechanism is unknown. Matrix proteinases play an important role in cell migration during cancer invasion and organ development. In this study, we therefore investigated in situ expression of matrix metalloproteinases (MMP) and tissue inhibitors of MMP (TIMP) during human intrahepatic bile duct development, using 32 human fetal livers. We also examined in situ expression of trypsinogen/trypsin, chymotrypsinogen/chymotrypsin, and cathepsin B, which are matrix proteinases and activators of MMP. MMP-1 expression was noted in ...

Human intrahepatic biliary epithelial cells were isolated from the livers of patients with primary biliary cirrhosis and from normal livers and established in primary culture. The in vitro expression of intercellular adhesion molecule-1, HLA class I, and HLA class II on biliary epithelial cells was studied in response to tumour necrosis factor-alpha (0-500 U/ml), interferon-gamma (0-500 U/ml), and interleukin-1 (0-5 U/ml) by immunohistochemical staining and a semiquantitative scoring system validated by spectrophotometry and previously validated by laser confocal microscopy. The non-stimulated expression of intercellular adhesion molecule-1 and HLA class II was higher on cells derived from the primary biliary cirrhosis liver than on cells from normal liver, a difference not seen with HLA class I expression. A statistically significant increase in intercellular adhesion molecule-1 expression was seen with all three cytokines in cells derived from both primary biliary cirrhosis and normal liver. ...

Cholangiocyte cytokines stimulate inducible nitric oxide synthase (NOS2) to produce nitric oxide (NO), a known DNA mutagen linked to malignant transformation (5, 13). The generation of NO is also important for bile duct development because it induces Notch1 expression (14, 15). The four Notch genes identified in mammals (Notch 1-4) are expressed in a wide variety of cells and play a significant role in cellular differentiation. The activation of Notch by cell-to-cell interaction causes a transcriptional silencing effect that inhibits differentiation in some cells but not in others (16-18). While the Notch pathway is known to be associated with pancreatic carcinogenesis in rats and humans (19), this same pathway may also have a role in cholangiocarcinogenesis via NOS2.. Cyclooxygenase-2 (prostaglandin-endoperoxide synthase 2, PTGS2) is also implicated in the initiation of malignant cholangiocytes (20). PTGS2 is up-regulated in murine and rat models of biliary adenocarcinoma, while the antisense ...

Hepatitis C virus (HCV) is a variable RNA virus that can readily establish persistent infection. Cellular immune responses are important in the early control of the virus. Evidence from animal models suggests that mutation in epitopes recognized by CD8+ T lymphocytes may play an important role in the establishment of persistence but in human persistent infection, equivalent evidence is lacking. We investigated this by analysing a unique resource: viruses from a set of chronically HCV-infected individuals in whom the CD8+ T-cell responses in liver had previously been accurately mapped. Virus was sequenced in seven individuals at 10 epitopes restricted by 10 human leucocyte antigen (HLA) molecules. Two main patterns emerged: in the majority of epitopes sequenced, no variation was seen. In three epitopes, mutations were identified which were compatible with immune escape as assessed using phylogenetic and/or functional studies.

INTRODUCTION: The liver is a multi-purposeful organ, susceptible to injury. Following acute injury, cells such as hepatocytes, regenerate, while latent hepatic progenitor cell (HPC) become active after chronic liver injury. Some studies suggest Fibroblast growth factors (FGF) may activate HPCs similarly to embryonic liver stem cells. In addition, Notch signaling is critical in bile duct development and injury. With progenitor cell transplantation as an alternative to tissue transplantation, we hypothesize that FGF and Notch signaling pathways induce proliferation of HPC after chronic liver injury.; MATERIALS AND METHODS: Wild-type mice were fed either regular or 0.1% 3,5-diethoxycarbonyl dihydrocollidine (DDC) chow to induce injury. Transgenic, dominant-negative RosartTA;tet(o)sFGFR2b+/- mice were given doxycycline 2 days prior and throughout DDC injury. mRNA and immunostaining of FGF and Notch receptors and ligands were performed. Cells isolated from transgenic mice were fluoresecently sorted ...

What Is Perihilar Scarring of the Lungs?What Is Perihilar Scarring of the Lungs?
Lung scarring can be a highly dangerous condition and is usually caused by inhaling dangerous chemicals or by infections. Lung scarring is generally defined by which area of the lung is injured, with the perihilar area, which is the major entrance for the major veins and arteries of the lungs, being the most common.

CoCC shows a variable histological morphology depending on the extent of the associated ICC/HCC components. Such an inherent histological heterogeneity potentially complicates the pathologic diagnosis of CoCC. Komuta et al. proposed that CoCC is defined as when the proportion of CoCC accounts for more than 90% of the entire tumor [8]. According to this strict definition, CoCC with a significant proportion of ICC or HCC components may be considered to be an ordinary ICC or HCC, respectively [4]. The authors also reported immunohistochemical findings of a positive EMA at the apical membrane [6, 8, 9], positive NCAM (a marker of hepatic progenitor cells), and negative S100P (a marker of intrahepatic large bile ducts) [8]. As described, we made an incorrect initial diagnosis of ordinary ICC in the present patient, primarily because a lack of knowledge of CoCC led us not to consider the possibility of CoCC. There may be a concern that pathological diagnosis of the recurrent lesions treated with RFA ...

Intrahepatic Cholangiocarcinoma (ICCA) Market Outlook. Intrahepatic cholangiocarcinoma (ICCA) is the type of CCA that forms in the bile ducts inside the liver. The commonly available modalities for the treatment of ICCA include surgery and radiation therapies for curative intent and systemic therapies, including chemotherapy and chemoradiotherapy, for the surgery of ineligible patients.. Surgical resection is the mainstay for the treatment of ICCA. The main goal of the surgery is the hepatic resection with negative margins. Since this type of cancer occurs in the bile ducts inside the liver, surgery may include removing the section or wedge of the liver, and ...

The natural history, treatment, and prognosis of this distinct cancer differ from hepatocellular carcinoma (HCC) or cholangiocarcinoma (CC) and are not completely understood. There is considerable controversy about the classification, treatment, and survival, which in turn is related to the rarity of the condition. Treatment options include surgical resection and the prognosis is believed to be better than CC but worse than HCC alone. Methods: We report a single-center liver ...

Lymphoepithelioma-like carcinoma (LELC) of the liver is extremely rare. To our knowledge, only 16 cases of pure LELC or LELC with ordinary adenocarcinoma arising in the hepatobiliary tract have been reported in the English literature.1-7 Most of these tumours (68%, 11/16) were positive for Epstein-Barr virus (EBV) by EBV-encoded small non-polyadenylated RNA (EBER-1) in situ hybridisation.1-6 However, association of intrahepatic cholangiocarcinoma bearing an intense lymphoplasmacytic infiltration with EBV infection has not been reported. We were the first to present two cases of intrahepatic cholangiocarcinoma with dense lymphoplasmacytic infiltration from Southern China, an area that is well known for and has a high-incidence of nasopharyngeal carcinoma, showing EBV infection, but one case of LELC was associated with EBV infection as well. ...

The original observations of this study relate to inflammation, NO production, DNA damage, and inhibition of DNA repair as related mechanisms for the development and/or progression of cholangiocarcinoma. Our results directly demonstrate the following: (a) human cholangiocarcinomas express the iNOS protein; (b) proinflammatory cytokines stimulate iNOS message and protein expression and the production of NO in cholangiocarcinoma cell lines; (c) the magnitude of NO produced is sufficient to cause single-stranded, double-stranded, and oxidative DNA lesions in the malignant cell lines; and (d) stimulated NO generation is associated with impaired global DNA repair activity in the cholangiocarcinoma cell lines. These data suggest that NO generated in response to inflammation may initiate malignant transformation of biliary epithelia and/or promote progression of established cholangiocarcinoma. Each of these observations is discussed in greater detail below.. iNOS expression with NO generation has been ...

Surgical resection remains the mainstay of curative treatment for intrahepatic cholangiocarcinoma (ICC). Prognosis after surgery is unsatisfactory despite improvements in treatment and post-operative clinical management. Despite developments in the molecular profiling of ICC, the preoperative prediction of prognosis remains a challenge. This study aimed to identify clinical prognostic indicators by investigating the molecular profiles of ICC and evaluating the preoperative imaging data of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET). A retrospective analysis was performed on 50 consecutive patients with ICC who underwent curative hepatectomy after 18F-FDG-PET examination. To evaluate the molecular profiles of ICC, KRAS mutation status was assessed in resected specimens. For the assessment of glucose uptake, we observed the expression of glucose transporter-1 (GLUT-1) by immunohistochemistry. The data of 18F-FDG-PET were re-evaluated as follows: maximum standardized uptake value,

Identification of Homer1 as a Potential Prognostic Marker for Intrahepatic CholangiocarcinomaIdentification of Homer1 as a Potential Prognostic Marker for Intrahepatic Cholangiocarcinoma
Background: The aim of the present study was to analyze whether Homer1 is a potential prognostic markerfor intrahepatic cholangiocarcinoma (ICC). Materials and Methods: The expression of Homer1 in ICC tissuewas detected with immunohistochemistry and levels of protein in ICC and paratumor tissues were evaluated byWestern blotting. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance.Results: Homer1 expression was high in 67.4% (58/86) of ICC samples, and there was significant differencebetween ICC and adjacent noncancerous tissues (p|0.001); high expression was associated with poor histologicdifferentiation (p=0.019), TNM stage (p=0.014), lymph node metastasis (p=0.040), and lymphatic invasion(p=0.025). On Kaplan-Meier analysis, a comparison of survival curves of low versus high expressors of Homer1revealed a highly significant difference in OS (p=0.001) and DFS (p=0.006), indicating that high expressionof Homer1 was linked with a worse prognosis.

Few studies have evaluated the risk of cancers other than hepatocellular carcinoma associated with hepatitis B virus (HBV) infection. This study aimed to estimate incidence rates of intrahepatic cholangiocarcinoma (ICC) and non-Hodgkin lymphoma (NHL) and its major subtypes in a nationwide cohort of parous women and to assess their associations with chronic HBV infection. We conducted a cohort study including 1,782,401 pregnant Taiwanese women whose HBV serostatus was obtained from the National Hepatitis B Vaccination Registry. Newly diagnosed ICCs and NHLs were ascertained through data linkage with the National Cancer Registry. Risks of ICC and NHL were assessed using Cox proportional hazards regression models. After a mean of 6.91 years of follow-up, there were 18 cases of ICC and 192 cases of NHL, including 99 cases of diffuse large B-cell lymphoma (DLBCL). Incidence rates of ICC were 0.09 and 0.43 per 100,000 person-years, respectively, among women who were hepatitis B surface antigen ...

The aim of this study was to compare the enhancement pattern of intrahepatic cholangiocarcinoma (ICC) on contrast-enhanced ultrasound (CEUS) with that on contrast-enhanced computed tomography (CECT). 40 pathologically proven ICC lesions in 40 patients were evaluated retrospectively with both CEUS and CECT. The enhancement level and pattern in the dynamic phases on both CEUS and CECT were analysed. The diagnostic results of CEUS and CECT before pathological examination were also recorded. During arterial phases, the number of lesions that appeared as (i) peripheral irregular rim-like hyperenhancement, (ii) diffuse heterogeneous hyperenhancement, (iii) diffuse homogeneous hyperenhancement and (iv) diffuse heterogeneous hypoenhancement were 19 (47.5%), 9 (22.5%), 5 (12.5%) and 7 (17.5%), respectively, on CEUS, and 22 (55.0%), 3 (7.5%), 2 (5.0%) and 13 (32.5%), respectively, on CECT (p = 0.125).

Intrahepatic cholangiocarcinoma (ICC) is an aggressive, highly lethal tumors and lacks of effective chemo and targeted therapies. Cell lines and animal models, even partially reflecting tumor characteristics, have limits to study ICC biology and drug response. In this work, we created and characterized a novel ICC patient-derived xenograft (PDX) model of Italian origin. Seventeen primary ICC tumors derived from Italian patients were implanted into NOD (Non-Obese Diabetic)/Shi-SCID (severe combined immunodeficient) mice. To verify if the original tumor characteristics were maintained in PDX, immunohistochemical (cytokeratin 7, 17, 19, and epithelial membrane antigen) molecular (gene and microRNA expression profiling) and genetic analyses (comparative genomic hybridization array, and mutational analysis of the kinase domain of EGFR coding sequence, from exons 18 to 21, exons 2 to 4 of K-RAS, exons 2 to 4 of N-RAS, exons 9 and 20 of PI3KCA, and exon 15 of B-RAF) were performed after tumor stabilization.

Hepatitis C virus infection of cholangiocarcinoma cell lines. - NDM Research BuildingHepatitis C virus infection of cholangiocarcinoma cell lines. - NDM Research Building
Hepatitis C virus (HCV) infects the liver and hepatocytes are the major cell type supporting viral replication. Hepatocytes and cholangiocytes derive from a common hepatic progenitor cell that proliferates during inflammatory conditions, raising the possibility that cholangiocytes may support HCV replication and contribute to the hepatic reservoir. We screened cholangiocytes along with a panel of cholangiocarcinoma-derived cell lines for their ability to support HCV entry and replication. While primary cholangiocytes were refractory to infection and lacked expression of several entry factors, two cholangiocarcinoma lines, CC-LP-1 and Sk-ChA-1, supported efficient HCV entry; furthermore, Sk-ChA-1 cells supported full virus replication. In vivo cholangiocarcinomas expressed all of the essential HCV entry factors; however, cholangiocytes adjacent to the tumour and in normal tissue showed a similar pattern of receptor expression to ex vivo isolated cholangiocytes, lacking SR-BI expression, explaining their

The purpose of this project is to evaluate the role of gadoxetate (Eovist) enhanced dual-energy CT in better evaluating perihilar cholangiocarcinoma, by exploiting the combination of the physiologic behavior of gadoxetate in liver tissue combined with the advantageous mass attenuation coefficient of Gadolinium achievable through dual energy technique. This combination of unique CT imaging sensitivity, high resolution and differential enhancement potentially allows improved visualization and detection of tumor relative to enhancing surrounding hepatic parenchyma and ductal anatomy in the hepatobiliary phase, due to the biliary excretion of the agent.. Cholangiocarcinoma is a hepatic adenocarcinoma that arises from the bile duct epithelium and is the second most prevalent liver cancer after hepatocellular carcinoma.

Molecular Pathogenesis of Cholangiocarcinoma | BMC Cancer | Full TextMolecular Pathogenesis of Cholangiocarcinoma | BMC Cancer | Full Text
Cholangiocarcinomas are a heterogeneous group of malignancies arising from a number of cells of origin along the biliary tree. Although most cases in Western countries are sporadic, large population-based studies have identified a number of risk factors. This review summarises the evidence behind reported risk factors and current understanding of the molecular pathogenesis of cholangiocarcinoma, with a focus on inflammation and cholestasis as the driving forces in cholangiocarcinoma development. Cholestatic liver diseases (e.g. primary sclerosing cholangitis and fibropolycystic liver diseases), liver cirrhosis, and biliary stone disease all increase the risk of cholangiocarcinoma. Certain bacterial, viral or parasitic infections such as hepatitis B and C and liver flukes also increase cholangiocarcinoma risk. Other risk factors include inflammatory disorders (such as inflammatory bowel disease and chronic pancreatitis), toxins (e.g. alcohol and tobacco), metabolic conditions (diabetes, obesity and non

Cholangiocarcinoma (CCA), cancer of the bile duct, is the first cause of cancer death of the people in the northeast of Thailand. The incidence of CCA in this region is highest not only in the country but in the world. CCA is a slow growing but highly metastatic tumor. At present, there is no standard chemotherapy or effective treatment for CCA. Most of the patients have short survival after diagnosis. Strong evidences from in vitro, animal and clinical studies indicate that vitamin D can prevent and control growth of cancer. Our preclinical studies in CCA cell lines, animal and patient tissue culture indicate that vitamin D effectively reduce growth of CCA. Supplementation of vitamin D to chemotherapeutic drugs enhance drug toxicity and better response. At present, there are several clinical trials in USA on supplementation of vitamin D or its analogs to cancer patients. The side effect or toxicity of using vitamin D supplementation is low, some patients had stable disease and some had good ...

Cholangiocarcinoma (CCA) is the second most common liver cancer and it is associated with a poor prognosis. CCA can be divided into intrahepatic, hilar and distal. Despite the subtype, the median survival is 12-24 months without treatment. Liver transplantation (LT) is worldwide recognized as a curative option for hepatocellular carcinoma. On the other hand, the initial results for LT for CCA were very poor mainly due to a lack of adequate patient selection. In the last two decades, improvement has been made in the management of unresectable hilar CCA, and the results of LT after neoadjuvant chemoradiation have been shown to be promising ...

Radiological Imaging for Assessing the Respectability of Hilar Cholangiocarcinoma: A Systematic Review and Meta-AnalysisRadiological Imaging for Assessing the Respectability of Hilar Cholangiocarcinoma: A Systematic Review and Meta-Analysis
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. Our data showed that CT had the highest pooled sensitivity at 95% (95% CI: 91–97), whereas PET/CT had the highest pooled specificity at 81% (95% CI: 69–90). The area under the curve (AUC) of CT, MRI, and PET/CT was 0.9269, 0.9194, and 0.9218, respectively. In conclusion, CT is the most frequently used imaging modality to assess HCC resectability with a good

Hepatocellular carcinoma (liver cell cancer) is the most common type of primary liver cancer. It is relatively rare in the United States but very common in Southeast Asia, especially China. The tumor predominantly affects males who are over 50 years of age, although it may arise in younger individuals or even children. The liver is also the primary site for cholangiocarcinomas (intrahepatic bile duct cancers) that are relatively rare and account for 10-20% of all primary liver cancers. These tumors occur in older individuals, usually after the age of 60. The overall median survival for hepatocellular carcinoma is 4 months and the overall 5-year survival rate is 3%. Cholangiocarcinomas have an overall mean survival time of less than 2 years. Several predisposing factors are thought to play a role in hepatocellular carcinoma. These include infection with hepatotropic viruses such as hepatitis B and C viruses, liver cirrhosis, liver cell dysplasia, exposure to aflatoxins and inborn errors of ...

Histamine regulates functions via four receptors (HRH1, HRH2, HRH3, and HRH4). The d-myo-inositol 1,4,5-trisphosphate (IP3)/Ca2+/protein kinase C (PKC)/mitogen-activated protein kinase pathway regulates cholangiocarcinoma growth. We evaluated the role of HRH3 in the regulation of cholangiocarcinoma growth. Expression of HRH3 in intrahepatic and extrahepatic cell lines, normal cholangiocytes, and human tissue arrays was measured. In Mz-ChA-1 cells stimulated with (R)-(α)-(−)-methylhistamine dihydrobromide (RAMH), we measured (a) cell growth, (b) IP3 and cyclic AMP levels, and (c) phosphorylation of PKC and mitogen-activated protein kinase isoforms. Localization of PKCα was visualized by immunofluorescence in cell smears and immunoblotting for PKCα in cytosol and membrane fractions. Following knockdown of PKCα, Mz-ChA-1 cells were stimulated with RAMH before evaluating cell growth and extracellular signal-regulated kinase (ERK)-1/2 phosphorylation. In vivo experiments were done in BALB/c ...

Background: iCCA is the 2nd most common liver malignancy and with a poor patient prognosis. The ABC-02 study established gemcitabine+cisplatin (gem-cis) as the standard of care (SOC) in 1st line (1L) systemic chemotherapy (CT). The objective was to examine the treatment (tx) patterns and time trends in the tx received by patients (pts) with iCCA in the United States before and after ABC-02 study was published. Methods: Retrospective data from the Optum Research Database, which included commercial and Medicare Advantage health plan members between January 1, 2006 and June 30, 2018, were used. Eligible pts were aged ≥ 18 years; had ≥ 2 nondiagnostic claims of primary iCCA diagnosis (International Classification of Disease [ICD]-9: 155.1 or ICD-10: C22.1) in the identification period (July 01, 2006-March 31, 2018); and had 6 months continuous enrollment prior to and ≥ 3 months follow-up (or less due to death) from the date of first diagnosis.

World Cholangiocarcinoma Day 2018 CCA: The factsWorld Cholangiocarcinoma Day 2018 CCA: The facts
In the west, the exact cause of cholangiocarcinoma is unclear. It is likely that this cancer arises due to a combination of factors, including other illnesses that cause chronic damage to the liver and/or bile ducts, certain toxins and possibly a small genetic predisposition, although it is not believed to be a directly inherited disease. Although most cases of cholangiocarcinoma are in people over 60 years of age, it appears to be increasing across all age groups including younger people. The cause of this ongoing rise is currently unknown.. In Southeast Asia, especially Thailand, which has the worlds highest incidence of cholangiocarcinoma, associated risk factors include eating raw fish infected with liver fluke and chronic typhoid, neither of which occurs in the western world.. ...

A110 Cholangiocarcinoma (CCA), a malignant tumor of the bile duct epithelium, is one of the major of cancers in Northeast Thailand. This disease is difficult to diagnose and has a high mortality rate, thus posing an important public health problem in this region. Generally, cancer arises from dysregulation of tumor suppressor genes and oncogenes. c-Met, hepatocyte growth factor (HGF) receptor, and its ligand, HGF, regulate diverse biological responses including proliferation, migration and invasion, key features of metastatic cancer. Overexpression of c-Met has frequently been found in cholangiocarcinoma especially of well-differentiated type suggesting the role of c-Met in cholangiocarcinogenesis. In this study the role of HGF in invasiveness of cholangiocarcinoma was investigated using the human CCA cell line, KKU-213, in which c- Met expression is high when compare to immortalized cholangiocyte, H-69. Activation of c-Met by HGF induced KKU-213 cell proliferation, invasion and motility. ...

The Hippo pathway effector Yes-associated protein (YAP) is localized to the nucleus and transcriptionally active in a number of tumor types, including a majority of human cholangiocarcinomas. YAP activity has been linked to chemotherapy resistance and has been shown to rescue KRAS and BRAF inhibition in RAS/RAF-driven cancers; however, the underlying mechanisms of YAP-mediated chemoresistance have yet to be elucidated. Herein, we report that the tyrosine phosphatase SHP2 directly regulates the activity of YAP by dephosphorylating pYAPY357 even in the setting of RAS/RAF mutations, and that diminished SHP2 phosphatase activity is associated with chemoresistance in cholangiocarcinomas. A screen for YAP-interacting tyrosine phosphatases identified SHP2, and characterization of cholangiocarcinomas cell lines demonstrated an inverse relationship between SHP2 levels and pYAPY357. Human sequencing data demonstrated lower SHP2 levels in cholangiocarcinomas tumors as compared with normal liver. Cell lines ...

Discussion This is the first study that demonstrates the effects of glyphosate on cholangiocarcinoma cells, and provides a better understanding of the possible mechanisms related to its effects. The low concentrations of glyphosate tested in this study are relevant to the range of levels that have been reported in the environment and detected in humans (Acquavella et al., 2004; Bai and Ogbourne, 2016; Kongtip et al., 2017). Previous studies have reported that E2 induces cell proliferation in an ERα expressing CCA, HuH28 cell line (Alvaro et al., 2006). It was reported that E2 also induced the expression levels of several proteins, including ERα, VEGF, VEGFR, IGF-1, and IGF-1R, as well as downstream signaling proteins associated to cell proliferation. In this study, we found that 10−11 to 10−5 M of glyphosate and E2 induced cell proliferation in HuCCA-1 cells under estrogen withdrawal conditions and the inductive effects were inhibited by ER antagonists. This study also demonstrated the ...

ABSTRACT: Beaked whales are among the least known group of cetaceans, and information regarding their pathology and parasitology are especially scarce. We describe a case of significant parasitism by a trematode found in the liver of an adult male Hubbs beaked whale Mesoplodon carlhubbsi that stranded in Hokkaido, Japan. Post-mortem examinations revealed a localised area of discolouration restricted to the hilar region of the left hepatic lobe, where spindle-shaped trematodes occupied the dilated and hypertrophic bile ducts. Histologically, the intrahepatic bile ducts were characterised by adenomatous hyperplasia with goblet cell metaplasia of the biliary epithelium. Findings in the adjacent hepatic parenchyma included pseudocarcinomatous ductular reactions obliterating hepatocytes, a histomorphology not previously reported in marine mammals. Morphological identification of the trematode corresponded to Oschmarinella macrorchis, which has only been reported once in a Stejnegers beaked whale M. ...
