N2 - Background: Hepatic artery based therapies (HAT) are offered for patients with unresectable intrahepatic cholangiocarcinoma (ICC). We aimed to evaluate the comparative effectiveness of HAT-hepatic arterial infusion (HAI), transcatheter arterial chemoembolization (TACE), drug-eluting bead TACE (DEB-TACE), and Yttrium90 radioembolization (Y-90) for unresectable ICC. Methods: A meta-analysis was performed using a prospectively registered search strategy at PROSPERO (CRD42013004830) that utilized PubMed (2003-2013). Primary outcome was median overall survival (OS), and secondary outcomes were tumor response to therapy and toxicity. Results: A total of 20 articles (of ...

Cholangiocarcinoma cells are dependent on antiapoptotic signaling for survival and resistance to death stimuli. to contribute to the effects of embelin on cholangiocarcinoma cells. Instead, embelin caused inhibition of cell proliferation and cell cycle analysis indicated that embelin increased the number of cells in S and G2/M phase. Our results demonstrate that embelin decreased VD2-D3 proliferation in cholangiocarcinoma cell lines. Embelin treatment resulted in decreased XIAP protein expression, but did not induce or enhance apoptosis. Thus, in cholangiocarcinoma cells the mechanism of action of embelin is probably not reliant on apoptosis. Introduction Cholangiocarcinoma can be a liver organ tumor with mobile top features of bile duct epithelial cells and may be the second most common major liver cancers. Biliary tract swelling predisposes to cholangiocarcinoma, although most individuals dont have identified underlying liver disease at the proper time of diagnosis. Chemotherapy offers been ...

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 aim of this study is to clarify the histopathological characteristics of h-CCC. Methods: On the basis of the findings in the arterial phase of contrast-enhanced computed tomography, 16 cases of mass-forming-type CCC were divided into two groups (h-CCC, n=8; o-CCC, n=8). Areas of high (Area H-a) and low (Area H-b) attenuation in h-CCC cases and areas of low attenuation in o-CCC cases (Area O) were delineated. These areas were then ...

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 ...

In a phase II Intergroup study (SWOG S0809) reported in the Journal of Clinical Oncology, Ben-Josef et al found that adjuvant capecitabine and gemcitabine followed by concurrent radiotherapy and capecitabine produced good survival results in patients with extrahepatic cholangiocarcinoma or gallbladder carcinoma.. Study Details. The study included 79 patients who had undergone radical resection and had stage pT2-4 or N+ or positive resection margins, M0, and a Zubrod performance status of 0 to 1. Patients received four cycles of gemcitabine 1,000 mg/m2 on days 1 and 8 and capecitabine 1,500 mg/m2/d on days 1 to 14 every 21 days followed by concurrent capecitabine 1,330 mg/m2/d and radiotherapy consisting of 45 Gy to regional lymphatics and 54 to 59.4 Gy to the tumor bed. The study was designed to estimate 2-year survival overall after R0 or R1 resection.. Of the 79 patients, 68% had extrahepatic cholangiocarcinoma, and 32% had gallbladder carcinoma; 68% had R0 resection, and 32% had R1 ...

Slug is an E-cadherin repressor and a suppressor of PUMA (p53 upregulated modulator of apoptosis) and it has recently been demonstrated that Slug plays an important role in controlling apoptosis. In this study, we examined whether Slugs ability to silence expression suppresses the growth of cholangiocarcinoma cells and/or sensitizes cholangiocarcinoma cells to chemotherapeutic agents through induction of apoptosis. We targeted the Slug gene using siRNA (Slug siRNA) via full Slug cDNA plasmid (Slug cDNA) transfection of cholangiocarcinoma cells. Slug siRNA, cisplatin, or Slug siRNA in combination with cisplatin, were used to treat cholangiocarcinoma cells in vitro. Western blot was used to detect the expression of Slug, PUMA, and E-cadherin protein. TUNEL, Annexin V Staining, and cell cycle analysis were used to detect apoptosis. A nude mice subcutaneous xenograft model of QBC939 cells was used to assess the effect of Slug silencing and/or cisplatin on tumor growth. Immunohistochemical staining was used

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. ...

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

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.

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,

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 ...

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.

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). In the portal phase, the number of lesions showing hyperenhancement and hypoenhancement were 1 (2.5%) and ...

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. The hilar intrahepatic variety of cholangiocarcinoma can present as an infiltrative, exophytic, or polypoid lesion. Most extra-hepatic cholangiocarcinomas are infiltrative, causing a ...

OBJECTIVES: Hepatocellular carcinoma and cholangiocarcinoma form the majority of primary hepatic tumours and are the third most common cause of cancer-related deaths. These liver tumours rapidly outgrow their vascular supply and become hypoxic, resulting in the production of hypoxia inducible factors and triggering the angiogenic switch. Therefore, inhibiting angiogenesis has proven to be a valuable therapeutic strategy in hepatocellular carcinoma, yet less is known about its use in cholangiocarcinoma. In this study, we assess whether inhibiting the placental growth factor (PlGF) could offer a therapeutic option in mice with hepatocellular carcinoma and cholangiocarcinoma. PlGF is a homologue of the vascular endothelial growth factor, which is only involved in pathological angiogenesis, therefore, its inhibition does not induce adverse effects. METHODS: We have used a chemically induced transgenic mouse model in which both hepatocellular carcinoma and cholangiocarcinoma develop after 25 weeks ...

Background and Aims: It is a challenge to collect samples from bile duct strictures to diagnose patients with cholangiocarcinoma. We investigated the utility of the Spyglass Spyscope, a single-operator endoscope that is used to perform cholangiopancreatoscopy, to identify extrahepatic cholangiocarcinoma in patients who were not diagnosed with this disorder by endoscopic retrograde cholangiopancreatography (ERCP) cytology or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) analyses. Methods: We conducted a retrospective analysis of data from 30 patients (median age, 67 years; 67percent male) with indeterminate extrahepatic biliary strictures who were ultimately diagnosed with cholangiocarcinoma but had inconclusive results from initial biliary ductal brush cytology and EUS-FNA analyses. Patients then underwent cholangioscopy by using the Spyglass Spyscope and intraductal biopsy analysis. None of the patients had a definitive mass in abdominal imaging or EUS analyses. Results: The ...

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

TRAIL in Combination with Subtoxic 5-FU Effectively Inhibit Cell Proliferation and Induce Apoptosis in Cholangiocarcinoma Cells Novel cancer therapy;TRAIL/Apo2L;non-conventional anti-cancer therapy;apoptosis; In the past decade, the incidence and mortality rates of cholangiocarcinoma (CCA) have been increasing worldwide. The relatively low responsiveness of CCA to conventional chemotherapy leads to poor overall survival. Recently, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL or Apo2L) has emerged as the most promising anti-cancer therapeutic agent since it is able to selectively induce apoptosis of tumor cells but not normal cells. In this study, we aimed to investigate the therapeutic effect of TRAIL in CCA cell lines (M213, M214 and KKU100) compared with the immortal biliary cell line, MMNK1, either alone or in combination with a subtoxic dose of 5-fluorouracil (5-FU). We found that recombinant human TRAIL (rhTRAIL) was a potential agent which significantly inhibited cell

Exosomes are part of extracellular vesicles(EVs), and can be secreted into the environment by many types of cells. It has been demonstrated that the content and function of exosomes depends on the originating cell and the conditions under which they are produced.Exosomes contain proteins,RNAs and lipid,which may transfer biological information and activities from donor cells to receptor cells. Non-coding RNAs are involved in many biological activities including tumor growth and metastasis.. In this prospective translational study, preclinical and clinical phases have been designed. On the first step, the main goal is to characterize the ncRNAs of cholangiocarcinoma derived exosomes. This exosome biomarker may provide a useful diagnostic tool. As a second step, the study will evaluate the prognostic and predictive value of cholangiocarcinoma exosomes levels in plasma in a prospectively recruited cohort of cholangiocarcinoma patients before and after surgical resection. ...

Postoperative Mortality after Liver Resection for Perihilar Cholangiocarcinoma: Development of a Risk Score and Importance of Biliary Drainage of the Future Liver Remnant.

BACKGROUND Surgery is the only curative therapy for patients with hilar cholangiocarcinoma (HCCA). Combined portal vein resection (PVR) could achieve negative resection margins in HCCA patients with portal vein invasion. This systematic review aimed to analysis the efficiency of combined PVR for HCCA. METHODS MEDLINE, EMBASE, the Cochrane Library, the Chinese National Knowledge Infrastructure database, and clinical trial registries were searched through April 2015. Risk ratios (RRs), and 95% confidence intervals (CIs) were calculated. RESULTS The analysis included 21 retrospective studies, altogether involving 2403 patients (patients with PVR, n=637; patients without PVR, n=1766). Patients with PVR were likely to have more advanced HCCA (lymphatic invasion: RR=1.14, 95% CI 1.02 to 1.28; perineural invasion: RR=1.31, 95% CI 1.05 to 1.63) and suffered less curative resections (RR=0.89, 95% CI 0.75 to 0.99). Postoperative morbidity was similar between patients with or without PVR (RR=1.06, 95% CI 0.94

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.. ...

Hilar cholangiocarcinoma (HCCA) frequently invades into the adjacent portal vein, and portal vein resection (PVR) is the only way to manage this condition and achieve negative resection margins. However, the safety and effectiveness of PVR is controversial. Studies analyzing the effect of PVR on the surgical and pathological outcomes in the management of HCCA with gross portal vein involvement were considered eligible for this meta-analysis. The outcome variables analyzed included postoperative morbidity, mortality, survival rate, proportion of R0 resection, lymph node metastasis, microscopic vascular invasion, and perineural invasion. From 11 studies, 371 patients who received PVR and 1,029 who did not were identified and analyzed. Data from patients who received combined PVR correlated with higher postoperative death rates (OR = 2.31; 95 % CI, 1.21-4.43; P = 0.01) and more advanced tumor stage. No significant difference was detected in terms of morbidity, proportion of R0 resection, or 5-year ...

Cholangiocarcinoma is a malignant tumor that originates from the bile duct epithelium (Roberts et al., 1997). Based on its anatomical location in the biliary tree, cholangiocarcinoma is conventionally classified by the World Health Organization as an intrahepatic (ICC) or extrahepatic cholangiocarcinoma (ECC) (Bosman et al., 2010; Patel, 2011). ICC and ECC are biologically distinct, and therefore manifest substantial differences in terms of incidence, mortality, and risk factors (Cardinale et al., 2010). Cholangiocarcinoma has a poor prognosis because it is notoriously difficult to diagnose due to its late clinical presentation, and is refractory to conventional chemotherapy and radiation therapy (Blechacz and Gores, 2008; Blechacz et al., 2011; Khan et al., 2012). Gemcitabine and cisplatin has become the standard regimen for patients with advanced or metastatic cholangiocarcinoma (Ramirez-Merino et al., 2013; Valle et al., 2010). However, response to the combination chemotherapy in ...

Cholangiocarcinoma (CCA) is a highly lethal malignant tumor arising from the biliary tract epithelium. that this Nes overexpression of IL-6 in CCA effectively suppresses the expression of miR-370 from your maternal allele, lending support to the theory that miR-370 silencing in human CCA follows a classic two-hit mechanism. Introduction Cholangiocarcinoma (CCA) is an Arry-380 aggressive tumor of the biliary tract [1]. CCAs are usually diagnosed late in their progression, and the patient survival is usually measured in months [2]. Molecular characterization of CCAs further suggested that inflammation and cholestasis, through modulation of genes involved in DNA damage repair, promote cancer development [1]. IL-6 is usually a recognized mitogen and survival factor in human CCA and can contribute to tumor pathogenesis or progression [3]. Therefore, it appears that elucidation of pathways downstream of IL-6 merits further investigation. DNA methylation refers to the addition of a methyl group to a ...

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

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 ...

Expression of MUC1 was detected immunohistochemically in 38 (76%) of 50 cases of m-ICC (ductal type, 18; cytoplasmic type, 20; and negative type, 12). Seventy-five percent of patients with lymph node metastasis had the cytoplasmic type MUC1 expression. Lymph node dissection was performed in only 20 patients, but significant correlation was demonstrated between MUC1 expression and lymph node metastasis (P = 0.0227). The location of MUC1 expression correlated with surgical outcome in m-ICC. Patients with the cytoplasmic type expression showed significantly lower survival rates. Univariate analysis revealed that MUC1 expression was a statistically significant risk factor affecting outcome in m-ICC (P = 0.0028). Furthermore, expression of MUC1 was found to be a statistically significant independent risk factor in multivariate analysis (P = 0.0063). ...

High-grade dysplasia/carcinoma in situ (HGD/CIS) of the biliary duct margin was found to not affect the prognosis of patients with extrahepatic cholangiocarcinoma by recent studies, but it has not yet reached a conclusion. Eligible studies were searched by PubMed, PMC, MedLine, Embase, the Cochrane Library, and Web of Science, from Jan. 1, 2000 to Jun. 30, 2019, investigating the influences of surgical margin status of biliary duct on the prognosis of patients with resectable extrahepatic cholangiocarcinoma. Overall survival (OS) and local recurrence were evaluated by odds ratio (OR) with 95% confidence interval (CI). A total of 11 studies were enrolled in this meta-analysis, including 1734 patients in the R0 group, 194 patients in the HGD/CIS group, and 229 patients in the invasive carcinoma (INV) group. The pooled OR for the 1-, 2-, and 3-year OS rate between HGD/CIS group and R0 group was 0.98 (95% CI 0.65~1.50), 1.01 (95% CI 0.73~1.41), and 0.98 (95% CI 0.72~1.34), respectively. The pooled OR for

However, its role in biliary cancers is unknown. The biological effects of TFFs may result from EGFR, PI3 kinase, COX-2 and STAT-mediated signaling. We investigated the expression of TFF-3, Erk, Akt, EGFR and COX-2 in biliary cancer. Methodology: Twenty-four consecutive cases of cholangiocarcinoma treated from 1996-2002 were studied. Immunohistochemistry was performed using monoclonal antibodies to TFF-3, EGFR, ...

Cholangiocarcinoma (bile duct cancer) usually develops in the bile duct system that arises from the liver and bile ducts and ends at the small intestine. Cancer that develops in the section of bile ducts within and outside the liver is called as intrahepatic and hilar cholangiocarcinoma, respectively. Distal cholangiocarcinoma is developed in the bile section that is associated with small intestine. Prognostic factors of cholangiocarcinoma are highly disputable.

Foreword by Steve This is a good video clip that gives insight into the future direction of immunotherapy. As a Cholangiocarcinoma patient living in Australia and trying to understand the what, how and where tos of this immunotherapy wave is vitally important to my decision making.

Background: Cholangiocarcinoma (CCA) is a serious malignant tumor. Long non-coding RNA NNT-AS1 (NNT-AS1) takes crucial roles in several tumors. So, we planned to research the roles and underlying mechanism of NNT-AS1 in CCA.Results: NNT-AS1 overexpression was appeared in CCA tissues and cell lines. Proliferation was promoted by NNT-AS1 overexpression in CCLP1 and TFK1 cells. Besides, NNT-AS1 overexpression reduced E-cadherin level and raised levels of N-cadherin, vimentin, Snail and Slug. However, the opposite trend was occurred by NNT-AS1 knockdown. Further, NNT-AS1 overexpression promoted phosphatidylinositol 3 kinase (PI3K)/AKT and extracellular signal-regulated kinase (ERK)1/2 pathways. MiR-203 was sponged by NNT-AS1 and miR-203 mimic reversed the above promoting effects of NNT-AS1. Additionally, insulin-like growth factor type 1 receptor (IGF1R) and zinc finger E-box binding homeobox 1 (ZEB1) were two potential targets of miR-203.Conclusion: NNT-AS1 promoted proliferation, EMT and PI3K/AKT and ERK1

Cholangiocarcinoma (CCA) cells paradoxically express the death ligand tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and thus rely on potent survival signals to circumvent cell death by TRAIL. Hedgehog (Hh) signaling is an important survival pathway in CCA. Herein, we further examine the mechanisms whereby Hh signaling mediates apoptosis resistance in CCA, revealing a pivotal role for the cell division regulating serine/threonine kinase polo-like kinase 2 (PLK2). We employed 50 human CCA samples (25 intrahepatic and 25 extrahepatic CCA) as well as human KMCH-1, Mz-CHA-1, and HUCCT-1 CCA cells for these studies. In vivo experiments were conducted using a syngeneic rat orthotopic CCA model. In human samples, polo-like kinase (PLK)1/2/3-immunoreactive cancer cells were present in the preponderance of intra- and extrahepatic CCA specimens. Inhibition of Hh signaling by cyclopamine reduced PLK2, but not PLK1 or PLK3, messenger RNA and protein expression in vehicle-treated and sonic ...

Researchers are exploring how broadly liquid biopsies might be used. In the Journal of Clinical Oncology: Precision Oncology, a Mayo Clinic research team reported the array of cancer-related genetic mutations present in liquid biopsies of bile duct cancer, a form of liver cancer also known as cholangiocarcinoma. We charted the landscape of genetic alterations present in circulating tumor DNA among patients with cholangiocarcinoma, explains Dr. Mody, the articles lead author. The team evaluated liquid biopsies in one of the largest patient cohorts to date: 124 patients with cholangiocarcinoma who were treated across Mayos three campuses. Our findings provide a foundation for further development of liquid biopsies as a way to advance precision medicine for patients with cholangiocarcinoma, he says.. Cholangiocarcinoma is uncommon in the U.S., where about 5,000 new cases are diagnosed each year, though numbers have been on the rise in recent decades. The cancer is more prevalent in Southeast ...

Aims: To compare the long-term prognosis of younger and elderly patients with combined hepatocellular-cholangiocarcinoma (CHC) who underwent curative resection between 1993 and 2014 at our center.. Methods: Two hundred and thirteen patients who underwent liver resection for CHC were enrolled in our study. The overall survival (OS) and disease-free survival (DFS) of elderly patients (age≥60, n=52) and younger patients (age,60, n=161) were compared by multivariate analysis and propensity score matching (PSM) analysis.. Results: Among the 213 CHC patients, the elderly patients had a higher rate of worse Child-Pugh grade (P=0.027), abnormal serum albumin (P,0.001) and lymphoid metastases (P=0.024). The proportion of HBV-positive CHC patients (74.6%, 159/213) was much higher than that observed in healthy cohorts. Younger patients had a higher rate of hepatitis B virus (HBV) infection compared to older patients (83.9% vs 46.2%, P,0.001). OS and DFS of the elderly and younger patients before and ...

Biliary tract cancers (BTC) comprise a group of rare and heterogeneous poor-prognosis tumours with the incidence of intrahepatic cholangiocarcinoma increasing over recent years. Combination chemotherapy with gemcitabine and cisplatin is the established first-line treatment for advanced BTC with a significant but modest survival advantage over monotherapy. There remains no accepted standard treatment in the second-line setting, although recent results from a randomised study have shown a survival benefit with 5-fluorouracil and oxaliplatin chemotherapy. Historically, clinical trials investigating targeted therapies in unselected BTC have failed to demonstrate significant clinical benefit. More recently, advancement in molecular exploration of BTC has shed light on the complex biological heterogeneity within these tumours and has also identified actionable genomic aberrations, such as fibroblast growth factor receptor 2 (FGFR2) gene fusions, isocitrate dehydrogenase (IDH) and BRAF mutations, which ...

Cholangiocarcinomas (CCCs) are malignancies of the biliary duct system that may originate in the liver and extrahepatic bile ducts, which terminate at the ampulla of Vater. CCCs are encountered in three anatomic regions: intrahepatic, extrahepatic (ie, perihilar), and distal extrahepatic.

Maffucci syndrome is characterized by the sporadic occurrence of multiple enchondromas together with multiple hemangiomas. Patients with Maffucci syndrome are at increased risk of developing different kinds of malignant tumors. We report on a 39-year-old woman who was diagnosed with Maffucci syndrome together with intrahepatic cholangiocarcinoma (IHCC). Heterozygous somatic mutations in the isocitrate dehydrogenase 1 and 2 (IDH1/IDH2) genes are associated with a number of different tumor types (e.g. IHCC) and also with Maffucci syndrome. For IHCC, mutations in IDH1/IDH2 are associated with higher survival rates. IHCC tissue as well as normal liver tissue and peripheral blood were analyzed for IDH1/IDH2-mutations in our patient. In the tumor sample, we identified a recurrent somatic IDH1-mutation affecting Arg132, while in normal liver tissue and peripheral blood, no variants were detected, as expected. This case report presents the second patient in the literature exhibiting the features of Maffucci

Background: The objective of the current study was to assess the impact of serum CA19-9 and CEA and their combination on survival among patients undergoing surgery for intrahepatic cholangiocarcinoma (ICC). Methods: Patients who underwent curative-intent resection of ICC between 1990 and 2016 were identified using a multi-institutional database. Patients were categorized into four groups based on combinations of serum CA19-9 and CEA (low vs. high). Factors associated with 1-year mortality after hepatectomy were examined. Results: Among 588 patients, 5-year OS was considerably better among patients with low CA19-9/low CEA (54.5%) compared with low CA19-9/high CEA (14.6%), high CA19-9/low CEA (10.0%), or high CA19-9/high CEA (0%) (P , 0.001). No difference in 1-year OS existed between patients who had either high CA19-9 (high CA19-9/low CEA: 70.4%) or high CEA levels (low CA19-9/high CEA: 72.5%) (P = 0.92). Although patients with the most favorable tumor marker profile (low CA19-9/low CEA) had the ...

Though much is known about the pathology of the rats liver during chemical carcinogenesis, and the associated biochemical changes have been studied extensively with some compounds, especially 4-dimethylaminoazobenzene (DAB, butter yellow), hardly any attempt has been made to follow such changes progressively or to correlate them with the histological findings. Malignant tumours of the liver are roughly divisible into cancers of the bile duct cells (cholangiocarcinomas) and those of the liver cells (hepatomas). In our experiments cholangiocarcinomas were produced by feeding thioacetamide or DAB, whereas hepatomas resulted if DAB with a vitamin B-rich diet was used. The events which decide the type of tumour which develops may be summarized thus: a cholangiocarcinoma occurs when the following changes are found in the liver, damage to parenchymal cells, proliferation of bile duct tissue, a drop in the mitochondrial fraction, and the phenomenon of ageing of mitochondria. During this time there ...

Liver tumors: One of the major areas of my research interest liver tumors. Some of the studies have been collaborative efforts with other academic Institutions in the country, while some have been my own. We have evaluated various markers that can be applied in the diagnostic work-up of hepatocytic masses, including hepatocellular carcinoma (HCC), hepatic adenoma (HA) and focal nodular hyperplasia (FNH) over the years. Our ongoing research in this area is looking at new markers and their diagnostic utility in the work-up of hepatic masses. We are also studying the HCCs that arise in patients with cirrhosis and chronic liver disorders and compare them with those without cirrhosis and known liver disease.. One of my major areas of research interest in liver tumors is Cholangiocarcinoma (CC). It is the second most common primary malignant neoplasm of the liver. The precursor lesions of cholangiocarcinoma are not well understood. Based on observations from clinical cases, we suspect that many of ...

Over the past decade, it has become apparent that the human polybromo-1 protein (BAF180) has a critical role in cancer. BAF180 is known to be a driver mutation in clear cell renal cell carcinoma, where it has been found to be mutated in approximately 40% of cases. Mutations have also been found in several other cancers, including intrahepatic cholangiocarcinomas and epithelioid sarcomas. BAF180 is the chromatin targeting subunit of the PBAF (Polybromo-associated BRG1-associated factor) chromatin remodeling complex, a role facilitated by its nine domains: six bromodomains, which recognize and bind to acetylated lysines on histones; two BAH (bromo-adjacent homology) domains, found to be critical for PCNA ubiquitination following DNA damage; and one HMG (high mobility group) box, the DNA binding component. Furthermore, proper expression of BAF180 has also been linked to cardiac development and cell cycle regulation. Despite these associations, the molecular level interactions of full-length BAF180 have yet

Dear All. Just updating on Mum.. We have had a bit of a rollercoaster over the last few months.. Mum was started on FOLFOX back in June…after having completed 11 Cycles of GEM/CIS. GEM/CIS was well tolerated.. FOLFOX was not so well tolerated and following two cycles was suspended by Mums oncologist. Main problem was tummy pains/some ascites. Not sure, however, whether the tummy pains were the chemo or the anti-sickness drugs.. Bone mets continue to wreak pain and we were fire fighting with radiotherapy. Then two weekends ago Mum woke up to such pain in her cervical vertebrae that we had to have her hospitalised. We thought she had fractured her neck or it was spinal cord compression. AN MRI confirmed it was just bone mets. She was discharged from hospital 3 days later with a new medication list, and a prescription for five fractions of radiotherapy to the cervical vertebrae area.. We followed the new pain medication list (which caused periodic wipe out for Mum) because it included diazepam ...

Cholangiocarcinoma (CCA) is a fatal cancer of the bile duct epithelial cell lining. The misdiagnosis of CCA and other biliary diseases may occur due to the similarity of clinical manifestations and blood tests resulting in inappropriate or delayed treatment. Thus, an accurate and less-invasive method for differentiating CCA from other biliary diseases is inevitable. We quantified methylation of OPCML, HOXA9, and HOXD9 in serum cell-free DNA (cfDNA) of CCA patients and other biliary diseases using methylation-sensitive high-resolution melting (MS-HRM). Their potency as differential biomarkers between CCA and other biliary diseases was also evaluated by using receiver operating characteristic (ROC) curves. The significant difference of methylation levels of OPCML and HOXD9 was observed in serum cfDNA of CCA compared to other biliary diseases. Assessment of serum cfDNA methylation of OPCML and HOXD9 as differential biomarkers of CCA and other biliary diseases showed the area under curve (AUC) of 0.850 (0

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.

Researchers in radiology at Memorial Sloan Kettering continue to assess multiple imaging methods in the quest to improve treatment options and success rates for patients with biliary cancers such as cholangiocarcinoma.

Dr. Stegalls Comments: There are many theories as to how cancer develops, and one of them is that cancer starts as a bacteria. The idea that bacteria could cause cholangiocarcinoma is an interesting one, as it would suggest a possible target for treatment using off-label antibiotic regimens. I typically include a low dose antibiotic given intravenously in periodic fashion as part of my treatment protocols, in case there is a bacterial component ...

Cell lines and human tissue samples. Cell lines from four human pancreatic carcinomas (SU8686, AsPC1, BxPC3, and CFPAC1), two gastric cancers (AGS and MKN7), three hepatic carcinomas (Alexander, Hep3B, and HepG2), a cholangiocarcinoma (HuCCT), and embryonic kidney (HEK293T) were purchased from the American Type Culture Collection (Manassas, VA) or the Japanese Riken Cell Bank (Tsukuba, Japan). Normal hepatocytes were purchased from Dainippon Pharma (Osaka, Japan) and normal diploid colonocytes (CCD841) were purchased from American Type Culture Collection. Tissue specimens obtained during surgery or endoscopic resection were obtained from the University of Tokyo Hospital (Tokyo, Japan) and Motojima Memorial Hospital (Gumma, Japan) after approval from the medical ethics committee and the acquisition of informed consent. Some samples of colonic cancer and surrounding precancerous tissue were collected from identical specimens. Formalin-fixed, paraffin-embedded sections were examined by H&E staining ...

The key purpose of the main part of the study is to assess efficacy and safety of anetumab ravtansine as monotherapy or combination therapy for mesothelin expressing advanced solid tumors. The main purpose of the safety lead-in (dose-finding) part of the study is to determine the safety and tolerability of anetumab ravtansine in combination with cisplatin and in combination with gemcitabine, and to determine the MTD of anetumab ravtansine in combination with cisplatin for mesothelin expressing advanced cholangiocarcinoma and in combination with gemcitabine for mesothelin expressing advanced adenocarcinoma of the pancreas. Patients will receive anetumab ravtansine every three weeks in monotherapy for most indications. In cholangiocarinoma and adenocarinoma of the pancreas, 3-weekly anetumab ravtansine is administered in combination with cisplatin or gemcitabine respectively (both administered in a 2 week on / 1 week off schedule). Treatment will continue until disease progression or until another ...
