Background and Aims: Angiogenesis is critically involved in the development of liver fibrosis, portal hypertension (PHT) and hepatocellular carcinoma (HCC). Regorafenib is a novel second-line therapy for HCC, but might also be beneficial in fibrosis and PHT even in absence of HCC. This study investigated the effects of regorafenib in experimental models without HCC. Methods: Fibrosis ( in vivo and in vitro ), inflammation, liver damage (aminotransferases), angiogenesis (matrigel implantation) and in vivo systemic and portal hemodynamics were assessed in different mouse and rat models (bile duct ligation, CCl4 , partial portal vein ligation) after acute and chronic treatment with regorafenib...

It is often difficult to correctly diagnose patients who present with dilation of the bile duct. Cholangiocarcinoma, primary sclerosing cholangitis (PSC) and immunoglobulin (Ig)G4-related sclerosing cholangitis must be considered as potential diagnoses for these cases. The current study presents a 73-year-old female patient who presented with a high fever and abdominal pain. Contrast-enhanced computed tomography and magnetic resonance cholangiopancreatography revealed stenosis and dilation of the intrahepatic bile duct without solid components...

BACKGROUND: SSBP2, single-stranded DNA binding protein 2, is a subunit of the ssDNA-binding complex that is involved in the maintenance of genome stability. The majority of previous studies have suggested a tumor-suppressive role of SSBP2, which is silenced by promoter hypermethylation in several human malignancies, such as hematologic malignancies, prostate cancer, esophageal squamous cell carcinoma, ovarian cancer, and gallbladder cancer. However, an oncogenic role of SSBP2 has been suggested in glioblastoma patients...

Inducible pluripotent stem (iPS) cells are multipotent stem cells that are produced by gene transfer of reprogramming factors to somatic cells. They are thought to be an important source of regenerative medicine because of their pluripotency and self-renewal ability. Although the liver has high regeneration ability, continuous death of hepatocytes due to chronic inflammation leads to liver cirrhosis and liver carcinoma. With regard to such serious liver diseases, liver transplantation is used as a complete cure, but there is a problem of donor shortage...

INTRODUCTION: Radical resection with or without preserving extra-hepatic bile duct has shown similar prognoses for gallbladder carcinoma (GB ca), although aggressive resection is essential. In preserving bile duct, ischemic complications are serious, life-threatening serious problems. Correct evaluation of the blood flow to the biliary tract is crucial. CASE PRESENTATION: A case of gallbladder ca in a 62-year-old man was reported. The patient was diagnosed with stage Ⅱ GB ca (T2, N0, M0) by ultrasonography, computed tomography, magnetic resonance imaging, and endoscopic ultrasonography...

RATIONALE: Clear cell renal cell carcinoma (CCRCC) metastasis to pancreas is clinically rare. Misdiagnosis for these cases is frequently due to the low incidence, lack of specific clinical symptoms, and laboratory results. PATIENT CONCERNS: Three female patients aged 47 years, 69 years, and 76 years, respectively, were admitted to hospital for routine examination after resection of clear cell carcinoma of kidney for 69 months, 57 months, and 123 months, respectively...

Upper abdominal pain, icterus and cholestasis are the symptoms leading to evaluation of the biliary tract. Together with its complications biliary stone disease is the main reason for inflammation of the biliary system. A distinction is made between acute and chronic variants. In chronic bile duct inflammation primary sclerosing cholangitis (PSC), primary biliary cirrhosis (PBC) and more recently IgG4-associated sclerosing cholangitis are of particular importance. Besides benign and tumor-like-lesions, malignant entities as gallbladder carcinoma and cholangiocarcinoma (CCC) in its three locations have to be mentioned...

BACKGROUND: Liver transplantation (LT) has become established therapy for end-stage liver disease and small-cell hepatocellular carcinoma (HCC), relying mainly on living donor LT (LDLT) in Taiwan. The cost of LDLT varies in different countries depending on the insurance system, the costs of the facility, and staff. In this study we aimed to investigate cost outcomes and determinants of LDLT in Taiwan. METHODS: From January 2014 to December 2015, 184 LDLT patients were enrolled in a study performed at the Kaohsiung Chang Gung Memorial Hospital...

INTRODUCTION: The World Health Organization (WHO) proposed an integrated classification for intraductal papillary neoplasm of the bile duct (IPNB) in 2010. However, IPNB reportedly shows considerable geographic variation. This Japanese single-institution study examined outcomes of surgery for IPNB and the prognostic impact of immunohistochemical mucin expression patterns. MATERIALS AND METHODS: Patients with IPNB were identified from 413 patients who underwent curative-intent surgery for biliary tract (excluding gallbladder) neoplasms from 1992 to 2016 by retrospective macro- and microscopic reevaluation of resected specimens...

Notch signaling is involved in both differentiation of hepatocyte progenitors and hepatocellular carcinoma (HCC). The mechanism whereby Notch signaling regulates cellular transformation in hepatocytes is still controversial. This study investigated the impact of overexpressing truncated intracellular Notch1 (NICD1) on transcriptomic profiles of immortalized human hepatocytes. RNA sequencing and gene ontology enrichment analysis revealed that extracellular matrix organization and hyaluronan biosynthesis process gene sets are among those affected by Notch hyperactivation...

Choledochal cysts are rare congenital anomalies of the biliary tree, which are more prevalent in female Asian population. Malignant transformation occurs in 10% to 30% of adults with choledochal cysts. A 39-year-old man presented with abdominal pain for 2 months, with irregular thickening of bile duct wall on ultrasound and enhanced CT. Staging with F-FDG PET/CT demonstrated lymph node and liver metastasis. F-FDG PET/CT may become a valuable imaging procedure in diagnosing and staging of carcinoma arising from choledochal cysts...

Primary hepatobiliary malignancies include a heterogeneous group of cancers with dismal prognosis, among which hepatocellular carcinoma (HCC), cholangiocarcinoma (CCA), and hepatoblastoma (HB) stand out. These tumors mainly arise from the malignant transformation of hepatocytes, cholangiocytes (bile duct epithelial cells) or hepatoblasts (embryonic liver progenitor cells), respectively. Early diagnosis, prognosis prediction and effective therapies are still a utopia for these diseases. Extracellular vesicles (EVs) are small membrane-enclosed spheres secreted by cells and present in biological fluids...

Intrahepatic cholangiocarcinoma (ICC) is the second most prevalent primary liver neoplasm after hepatocellular carcinoma (HCC), corresponding to 10% to 15% of cases. Pathologies that cause chronic biliary inflammation and bile stasis are known predisposing factors for development of ICC. The incidence and cancer-related mortality of ICC is increasing worldwide. Most patients remain asymptomatic until advance stage, commonly presenting with a liver mass incidentally diagnosed. The only potentially curative treatment available for ICC is surgical resection...

INTRODUCTION: Trimethylation of histone H3K36 (H3K36me3), an epigenetic marker of transcription-associated histone modification and stem cell regulation, is expressed in a variety of human cancers. This study elucidated the prognostic significance of H3K36me3 in patients with resectable hepatocellular carcinoma (HCC). METHODS: Expression of H3K36me3 was retrospectively evaluated through immunohistochemistry in 152 surgically resected primary HCCs. RESULTS: In nontumorous liver parenchyma, H3K36Me3 was detected in bile ducts but not in hepatocytes...

OBJECTIVE: After recent evaluations of the ALPPS registry, with perioperative results sobering in particular for central bile duct carcinomas, the initial euphoria for this procedure disappeared. It is thus desirable to modify the concept of reducing the invasiveness and high complication rate of the procedure. INDICATIONS: Below we report a 72-year-old female patient with a gallbladder carcinoma locally infiltrating and metastatic to segments 4 b and 5. Due to a too small future liver remnant volume of segments 1 - 3 before planned extended right hemihepatectomy, we planned a laparoscopic partial PVE-ALPPS for hypertrophy induction...
