Gut Liver 2019 Apr 24. Epub 2019 Apr 24.

Department of Gastroenterology, Iida Municipal Hospital, Iida, Japan.

As ultrasound (US) is simple and less invasive than other imaging modalities, this technique is widely used for mass screening. However, visualizing the entire pancreas due to complicated anatomy, obesity and overlying gas can be difficult. US plays a key role in the diagnosis of pancreatic carcinoma (PC), of which tumors smaller than 10 mm (TS1a) and pancreatic carcinoma in situ (PCIS) are expected to have good prognosis. Read More

Characterization of Intraductal Papillary Neoplasm of the Bile Duct with Respect to the Histopathologic Similarities to Pancreatic Intraductal Papillary Mucinous Neoplasm.

Gut Liver 2019 Apr 15. Epub 2019 Apr 15.

Department of Hepatobiliary Pancreatic Surgery, Shizuoka Cancer Center, Sunto, Japan.

Intraductal papillary neoplasms of the bile duct (IPNBs) are known to show various pathologic features and biological behaviors. Recently, two categories of IPNBs have been proposed based on their histologic similarities to pancreatic intraductal papillary mucinous neoplasms (IPMNs): type 1 IPNBs, which share many features with IPMNs; and type 2 IPNBs, which are variably different from IPMNs. The four IPNB subtypes were re-evaluated with respect to these two categories. Read More

Proc (Bayl Univ Med Cent) 2019 Jan 7;32(1):124-125. Epub 2019 Jan 7.

Department of Pathology, Baylor University Medical CenterDallasTexas.

Intraductal papillary neoplasm of the bile duct is characterized by intraductal papillary growth with fibrovascular cores that can grow anywhere along the biliary tree. Most cases have high-grade intraepithelial neoplasia or an associated invasive carcinoma. These tumors can spread superficially along the biliary tree and be multifocal, and preoperative biopsy cannot always reflect the maximum degree of atypia. Read More

A dichotomous imaging classification for cholangiocarcinomas based on new histologic concepts.

Eur J Radiol 2019 Apr 19;113:182-187. Epub 2019 Feb 19.

Department of Pathology, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea. Electronic address:

We noted the limitations of applying conventional macroscopic patterns to classify the imaging features of cholangiocarcinoma (CCA). Therefore, we hereby propose a dichotomous imaging classification of "parenchymal" and "ductal" types, based on recent developments in the histopathologic concepts of CCA. This new imaging classification of CCA is simple and easy to apply, and can be useful to describe underlying carcinogenesis and correlate clinicopathologic characteristics with imaging patterns of CCA.

Pathways- and epigenetic-based assessment of relative immune infiltration in various types of solid tumors.

Adv Cancer Res 2019 6;142:107-143. Epub 2019 Mar 6.

3R Biosystems, Long Beach, CA, United States.

Recent clinical studies document the power of immunotherapy in treating subsets of patients with advanced cancers. In this context and with multiple cancer immunotherapeutics already evaluated in the clinic and a large number in various stages of clinical trials, it is imperative to comprehensively examine genomics data to better comprehend the role of immunity in different cancers in predicting response to therapy and in directing appropriate therapies. The approach we chose is to scrutinize the pathways and epigenetic factors predicted to drive immune infiltration in different cancer types using publicly available TCGA transcriptional and methylation datasets, along with accompanying clinico-pathological data.

Anatomical, histomorphological, and molecular classification of cholangiocarcinoma.

Liver Int 2019 Mar 18. Epub 2019 Mar 18.

Department of Movement, Human and Health Sciences, Division of Health Sciences, University of Rome "Foro Italico", Rome, Italy.

Cholangiocarcinoma constitutes a heterogeneous group of malignancies that can emerge at any point of the biliary tree. Cholangiocarcinoma is classified into intrahepatic, perihilar and distal based on its anatomical location. Histologically, conventional perihilar/distal cholangiocarcinomas are mucin-producing adenocarcinomas or papillary tumors; intrahepatic cholangiocarcinomas are more heterogeneous and can be sub-classified according to the level or size of the displayed bile duct.

Experimental and pan-cancer genome analyses reveal widespread contribution of acrylamide exposure to carcinogenesis in humans.

Genome Res 2019 04 7;29(4):521-531. Epub 2019 Mar 7.

Molecular Mechanisms and Biomarkers Group, International Agency for Research on Cancer, Lyon 69008, France.

Humans are frequently exposed to acrylamide, a probable human carcinogen found in commonplace sources such as most heated starchy foods or tobacco smoke. Prior evidence has shown that acrylamide causes cancer in rodents, yet epidemiological studies conducted to date are limited and, thus far, have yielded inconclusive data on association of human cancers with acrylamide exposure. In this study, we experimentally identify a novel and unique mutational signature imprinted by acrylamide through the effects of its reactive metabolite glycidamide. Read More

Section of General, Thoracic and Vascular Surgery, Virginia Mason Medical Center, 1100 Ninth Avenue, Seattle, WA 98101, USA. Electronic address:

Although the most common presentation of biliary disorder in North America is secondary to gallstone disease, an awareness of benign biliary cystic neoplasms is important because of the risk of malignant transformation. The incidence of premalignant cystic neoplasms of the bile duct is not well characterized and they often are detected incidentally for suspicion of other abdominal disorders. This article describes the 4 most common premalignant biliary cystic neoplasms: biliary mucinous cystic neoplasms, intraductal papillary mucinous neoplasms of the bile duct, intraductal tubular papillary neoplasms of the bile duct, and choledochal cysts.

Large Liver Blood Vessels and Bile Ducts Are Not Damaged by Electrochemotherapy with Bleomycin in Pigs.

Sci Rep 2019 Mar 6;9(1):3649. Epub 2019 Mar 6.

Institute of Oncology Ljubljana, Zaloska cesta 2, 1000, Ljubljana, Slovenia.

The first clinical studies on the use of electrochemotherapy to treat liver tumours that were not amenable to surgery or thermal ablation techniques have recently been published. However, there is still a lack of data on the effects of electrochemotherapy on normal liver tissue. Therefore, we designed a translational animal model study to test whether electrochemotherapy with bleomycin causes clinically significant damage to normal liver tissue, with emphasis on large blood vessels and bile ducts.

Percutaneous transhepatic cholangiobiopsy.

Radiol Bras 2019 Jan-Feb;52(1):41-42

Universidade Federal do Rio de Janeiro (UFRJ), Rio de Janeiro, RJ, Brazil.

Most tumors of the biliary tract are too small to have specific imaging characteristics or for percutaneous puncture to provide sufficient material for diagnosis. Percutaneous transhepatic biliary drainage, in addition to being a well-established technique in the treatment of obstructive jaundice, provides adequate access for sampling obstructive lesions. In cases of biliary lesions, percutaneous transhepatic biopsy of the biliary tract has proven to be a useful diagnostic technique, with a reported accuracy of over 90% at some referral centers.

Cancer risk in primary sclerosing cholangitis: Epidemiology, prevention, and surveillance strategies.

World J Gastroenterol 2019 Feb;25(6):659-671

Division of Gastroenterology, Department of Medicine, Olive View-UCLA Medical Center, Sylmar, CA 91342, United States.

Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by progressive fibroinflammatory destruction of the intra- and/or extrahepatic biliary ducts. While its features and disease course can be variable, most patients with PSC have concurrent inflammatory bowel disease and will eventually develop liver cirrhosis and end-stage liver disease, with liver transplantation representing the only potentially curative option. Importantly, PSC is associated with a significantly increased risk of malignancy compared to the general population, mainly cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, and colorectal cancer, with nearly 50% of deaths in patients with PSC being due to cancer.

Analysis of intrahepatic sarcomatoid cholangiocarcinoma: Experience from 11 cases within 17 years.

World J Gastroenterol 2019 Feb;25(5):608-621

Department of Internal Medicine, Dong-A University College of Medicine, Busan 49201, South Korea.

Background: Intrahepatic sarcomatoid chonalgiocarcinoma (s-CCC) is an extremely rare disease, accounting for less than 1% of hepatobiliary system malignancies, and its pathophysiology is not well known. On the hypothesis that its clinical, serologic, or radiologic diagnosis are not fully understood and its prognosis is poor, we investigated the distinguishing features of s-CCC compared with those of intrahepatic bile duct adenocarcinoma [cholangiocellular carcinoma (CCC)] in patients from a single center.

Aim: To analyze the clinical, serologic, imaging, and histopathologic characteristics of intrahepatic s-CCC patients diagnosed in a single center. Read More

Overexpression of matriptase in tumor stroma is a poor prognostic indicator of extrahepatic bile duct cancer.

Pathol Int 2019 Feb 6;69(2):86-93. Epub 2019 Feb 6.

Department of Pathology, Jichi Medical University, 3311-1 Yakushiji, Shimotsuke-shi, Tochigi-ken, Japan, 329-0498.

Bile duct cancer is known to contain numerous fibroblasts, and reported to recruit cancer- associated fibroblasts by secreting platelet-derived growth factor-D (PDGF-D) which needs serine proteases, such as matriptase, to behave as a ligand. However, their expression pattern, and prognostic value have not been clarified. In this study, we investigated the clinicopathological significance of PDGF-D and matriptase expression in patients with extrahepatic bile duct cancer. Read More
