Epidermal growth factor receptor (EGFR) and downstream signal transducer and activator of transcription 3 (STAT3) signaling have been extensively implicated in various human neoplasms. Recently, a novel EGFR inhibitor, known as afatinib, has exhibited broad antitumor activities in a variety of tumors. Therefore, the present study attempted to investigate the impact of this agent on intrahepatic cholangiocarcinoma (ICC). Initially, immunohistochemical assays were performed on 15 human ICC specimens and their adjacent tissues in order to assess the protein levels of phosphorylated EGFR (pEGFR) and pSTAT3...

Intrahepatic cholangiocarcinoma(ICC) is generally found late along with extremely poor prognosis and lack of effective and standardized treatment. Tremendous heterogeneities exist in onset factors, geographic distribution, clinical manifestation, and biological characteristics of ICC patients. However, the relevant causes and mechanisms have not been clearly illustrated. Recent studies indicate that the diverse celluar origins of ICC, including liver cells, bile duct epithelial cells, glandular cells around the duct, and liver stem cells, etc...

Rab1a, a member RAS oncogene family, has been reported playing important role in tumor proliferation and migration. However, the role of Rab1a in intrahepatic cholangiocarcinoma (ICC) is not clear. In this study, we found Rab1a was overexpressed in ICC tissues both in mRNA and protein level. Kaplan-meier analysis showed that high expression of Rab1a was associated with poor prognosis of ICC patients. Suppression of Rab1a led to lower proliferation rate and migration ability both in vitro and in vivo by inhibiting process of cell cycle and Epithelial-Mesenchymal Transition (EMT)...

A CT scan was performed on a 67-year-old man newly diagnosed with acute pancreatitis. The scan revealed a low-density lesion in the liver, a left renal nodule, and a right renal cystic mass. Intense F-FDG uptake was observed in the liver lesion and left renal nodule. No abnormal uptake was observed in the right renal mass. In addition, another focal intense uptake was observed in segment VII of the liver. Biopsies revealed intrahepatic cholangiocarcinomas in the 2 liver lesions, papillary renal cell carcinoma in the left renal lesion and clear cell renal cell carcinoma in the right renal lesion...

BACKGROUND: Primary liver cancer (PLC) is the third largest contributor to cancer mortality in the world. PLC is a heterogeneous disease that encompasses several biologically distinct subtypes including hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular-cholangiocarcinoma (CHC). CHC is a distinct, albeit rare, subtype of PLC and is comprised of cells with histopathological features of both HCC and ICC. Several studies have focused on the mutation and expression landscapes of HCC and ICC...

Infectious agents, such as HCV, account for ∼15% of human cancers. HCV infects not only hepatocytes but also extrahepatic cells. Chronic HCV infection can induce chronic inflammation with qualitative and quantitative alterations of the immune repertoire and tissue microenvironment, which could induce various neoplasias. Epidemiological studies and meta-analyses suggest an increased rate of extrahepatic cancers in patients with chronic HCV infection along with a higher risk of intrahepatic cholangiocarcinoma, pancreatic cancer and non-Hodgkin lymphoma (NHL), highlighting the need to screen for HCV infection in patients with these cancers...

Cholangiocarcinoma (CCC) is an aggressive malignancy with poor therapeutic options and pronounced chemotherapy resistance. The bioactive broccoli substance, sulforaphane (SFN), is a promising new therapeutic option since it has been found to induce therapeutic effects in both experimental and epidemiological studies in various tumor entities. Thus, the present study was designed to assess the effect of SFN on cisplatin sensitivity in CCC. Human HuCCT-1 and TFK-1 cells, representing intrahepatic and extrahepatic CCC, respectively, were treated with cisplatin and SFN...

BACKGROUND: Isocitrate dehydrogenase 1 (IDH1) mutation is common in low-grade glioma (approximately 80%) and acute myeloid leukemia (approximately 10%). Other than brain tumor or hematologic malignancies, intrahepatic cholangiocarcinoma (iCC) is a well-known solid tumor with IDH1 mutation (6.8-20%). Histologically, poor differentiation and clear cell change are associated with IDH1 mutation in iCC. Since hepatocellular carcinoma (HCC) shares histologic features with iCC, some specific subtypes of HCC might show a higher IDH1 mutation rate than reported before (0...

Clear-cell cholangiocarcinoma is a very uncommon variant of cholangiocarcinoma with a largely unknown natural history and prognosis. We report a case of a 51-year-old previously healthy woman presenting with a large liver nodule found on routine imaging. Needle biopsy of the lesion suggested a non-hepatocellular carcinoma. After extensive workup for other primary neoplasms, the patient underwent a partial hepatectomy. Histopathology was compatible with a moderately differentiated clear-cell cholangiocarcinoma...

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)...

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...
