OBJECTIVE: To investigate differential diagnosis between intrahepatic cholangiocarcinoma (ICC) and arterial phase enhanced hepatic inflammatory lesions in patients without liver cirrhosis using contrast-enhanced ultrasound (CEUS). METHODS: ICC and hepatic inflammatory lesions cases with CEUS and pathological diagnosis between Sep 2013 and Oct 2016 were investigated retrospectively. Imaging features of conventional ultrasound and CEUS were analyzed. The parameters of time intensity curve (TIC), including the arrival time, peak intensity (PI) in the lesions, the starting time for washout, and the intensity difference at 3 min (ΔI3) after contrast agent infection between the lesion and the liver parenchyma, were compared between ICC and hepatic inflammatory lesions...

BACKGROUND: The benefit of adjuvant chemotherapy for resected intrahepatic cholangiocarcinoma (ICC) is unclear. The aim of the current study was to investigate the impact of adjuvant chemotherapy on survival among patients undergoing resection of ICC using a multi-institutional database. METHODS: 1154 ICC patients undergoing curative-intent hepatectomy between 1990 and 2015 were identified from 14 institutions. Cox proportional hazard modeling was used to determine the impact of adjuvant chemotherapy on overall survival (OS)...

The role of adjuvant therapy following resection of biliary tract cancer (BTC) remains unclear. We therefore evaluated the feasibility and toxicity of adjuvant gemcitabine in patients with BTC. This clinical phase II trial was an open-label, single center, single-arm study. Within 8 weeks after gross complete resection of BTC, patients were started on intravenous infusions of gemcitabine 1000 mg/m2 over 30 min on days 1, 8, and 15 of every 28-day cycle. Intratumoral expression of cytidine deaminase (CDA), human equilibrative transporter-1 (hENT1), deoxycytidine kinase (dCK) and ribonucleotide reductase subunit 1 (RRM1) was measured by immunohistochemistry...

Tumor tissue has great clinical and scientific value which relies highly on the proper preservation of primary materials. Conventional tumor tissue cryopreservation using slow-freezing method has yielded limited success, leading to significant cell loss and morphological damage. Here we report a standardized vitrification-based cryopreservation method, by which we have successfully vitrified and warmed 35 intrahepatic cholangiocarcinoma (ICC) tissues with up to 80% viability of the fresh tumor tissues. Cryopreserved ICC tissue could generate patient-derived xenografts (PDXs) with take rates of 68...

The prognosis of primary liver cancer (PLC) remains poor and is explained by the slow progress in understanding the molecular pathways driving tumorigenesis, therapeutic resistance and relapse. For early PLCs, complete surgical resection is the only effective treatment, with sorafenib and, more recently, regorafenib prolonging overall survival by a few months. Areas covered: Application of next-generation sequencing (NGS), including targeted NGS (tNGS), whole-exome sequencing (WES), whole-genome sequencing (WGS) and RNA sequencing (RNAseq), on clinical samples from patients with hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) could aid in comprehending tumorigenesis, genetic and genomic heterogeneity, as well as developing molecular classifications for specialized targeted therapy...

INTRODUCTION: We sought to validate the commonly used prognostic models and staging systems for intrahepatic cholangiocarcinoma (ICC) in a large multi-center patient cohort. METHODS: The overall (OS) and disease free survival (DFS) prognostic discriminatory ability of various commonly used models were assessed in a large retrospective cohort. Harrell's concordance index (c-index) was used to determine accuracy of model prediction. RESULTS: Among 1054 ICC patients, median OS was 37...

Intrahepatic cholangiocarcinoma (ICC) is a relatively rare form of liver cancer with a poor prognosis. The therapeutic options for patients with advanced ICC are limited and usually ineffective. There is currently no approved targeted therapy for ICC, although accumulating evidence supports inhibition of the PI3K/Akt/mTOR signaling pathway as a promising therapeutic strategy in the treatment of ICC. Here, we report a patient with stage IV ICC harboring a PIK3CA mutation who responded well to the mTOR inhibitor everolimus...

Biliary tract cancer accounts for <1% of all cancers and affects chiefly an elderly population, with predominance in men. We distinguish cholangiocarcinoma (intrahepatic, hilar and distal) and gallbladder cancer, with different pathogenesis and prognosis. The treatment is based on surgery (whenever possible), radiotherapy in selected cases, and chemotherapy. The standard cytotoxic treatment for advanced/metastatic disease is represented by the combination of gemcitabine and cisplatin, whereas fluoropyrimidines are generally administered in second line setting...

Biliary tract cancer (BTC) is one of the most devastating types of malignant neoplasms worldwide. However, the mechanisms underlying the development and progression of BTC remain unresolved. BTC includes extrahepatic bile duct carcinoma (EBDC), gallbladder carcinoma (GBC) and ampulla of Vater carcinoma (AVC), named according to the location of the tumor. Although genetic alterations of intrahepatic cholangiocarcinoma have been investigated, those of EBDC, GBC and AVC have not yet been fully understood. The present study analyzed somatic mutations of 50 cancer-associated genes in 27 Japanese BTC cells, including: 11 EBDC, 14 GBC and 2 AVC...

An effective serum biomarker may improve cholangiocarcinoma (CCA) management. Periostin (PN) has been demonstrated to be associated with aggressive CCA. The current study evaluated PN in blood serum for its diagnostic and prognostic potential in patients with CCA. Sera of 68 patients with CCA were collected prior to treatment, and PN levels were measured using an ELISA. Sera from 50 normal controls, 6 patients with benign liver diseases, 2 with hepatocellular carcinoma and 21 with breast cancer were analyzed...

X-linked ribosomal protein S4 (RPS4X) has previously been reported to be associated with cisplatin resistance and clinical outcome in bladder and ovarian cancer. However, the value of RPS4X as a diagnostic and prognostic marker in intrahepatic cholangiocarcinoma (ICC) has not yet been investigated. The present study evaluated the expression pattern, and diagnostic and prognostic value of RPS4X in patients with ICC. Retrospective analysis was performed for a total of 201 patients with intrahepatic cholangiocarcinoma, and 8 patients with inflammation of the bile duct...

Epidemiologic studies show an increased risk of mortality among hepatitis C virus (HCV)-infected individuals compared with uninfected individuals from hepatic and nonhepatic causes. This article reviews the biologic plausibility of and epidemiologic evidence for the association between HCV and five extrahepatic malignancies: cholangiocarcinoma (CCA), pancreatic adenocarcinoma, papillary thyroid cancer, oral squamous cell cancer, and renal/kidney cancer. There is sufficient evidence to suggest that HCV is associated with intrahepatic CCA...

BACKGROUND: Previous studies have demonstrated a strong association between the preoperative neutrophil-to-lymphocyte ratio and the outcomes of patients with resected hepatocellular carcinoma and colorectal liver metastases. However, the predictive ability of neutrophil-to-lymphocyte ratio in patients with intrahepatic cholangiocarcinoma, especially those treated with preoperative chemotherapy, has been less well described. METHODS: The clinicopathological characteristics, overall survival, and recurrence free survival of all patients with intrahepatic cholangiocarcinoma resected between 2000-2015, were compared between those with elevated (≥3...

A 78-year-old man was referred to our hospital with suspected liver abscess. Fever and inflammatory reaction resolved after percutaneous drainage and administration of antibiotics. However, leukocyte count was remarkably increased, and hypercalcemia was noted. The liver mass was also enlarged, as observed in the follow-up abdominal CT scans. Therefore, a percutaneous needle biopsy was performed, and the histopathological findings indicated the presence of adenocarcinoma. Additional blood examination revealed high serum levels of granulocyte colony-stimulating factor (G-CSF) and parathyroid hormone-related protein (PTHrP)...

The ErbB/HER family comprises four distinct tyrosine kinase receptors, EGFR/ErbB1/HER1, ErbB2/HER2, ErbB3/HER3 and ErbB4/HER4, which trigger intracellular signals at the origin of essential cellular functions including differentiation, proliferation, survival and migration. Epithelial cells, named cholangiocytes, that line intrahepatic and extrahepatic bile ducts, contribute substantially to biliary secretory functions and bile transport. Although ErbB receptors have been widely studied in cholangiocarcinoma (CCA), a malignancy of the biliary tract, knowledge of these receptors in biliary epithelium physiology and in non-malignant cholangiopathies is far from completed...

Liver cancer is the second leading cause of death worldwide. As such, establishing animal models of the disease is important for both basic and translational studies that move toward developing new therapies. Gankyrin is a critical oncoprotein in the genetic control of liver pathology. In order to evaluate the oncogenic role of gankyrin without cancer cell inoculation and drug treatment, we overexpressed gankyrin under the control of the fabp10a promoter. A Tet-Off system was used to drive expression in hepatocytes...

BACKGROUND: Stereotactic ablative radiotherapy (SABR) is a safe and effective modality in patients with liver cancer who are ineligible for other local therapies. However SABR is not current standard of practice and requires further validation. Patient reported quality of life (QOL) is key to this validation, yet no systematic reviews to date have been performed to analyse QOL following liver SABR. QOL is a critical part of therapy evaluation, particularly in disease states with short life expectancy...
