Utility of CD138/syndecan-1 immunohistochemistry for localization of plasmacytes is tissue-dependent in B6 mice.

BMC Res Notes 2022 Jun 25;15(1):219. Epub 2022 Jun 25.

Department of Pathology, University of Iowa, Iowa City, IA, USA.

Objective: Inflammation is present in many diseases and identification of immune cell infiltration is a common assessment. CD138 (syndecan-1) is a recommended immunohistochemical marker for human plasmacytes although it is also expressed in various epithelia and tumors. Similarly, CD138 is a marker for murine plasmacytes, but its tissue immunostaining is not well-defined. Read More

Arq Bras Cir Dig 2022 17;35:e1658. Epub 2022 Jun 17.

Department of General Surgery, Hospital Nossa Senhora da Conceição (HNSC) - Porto Alegre - RS - Brazil.

Aim: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the digestive tract and has a wide variation in biological behavior; surgical resection remains the main form of treatment.

Current updates and future directions in diagnosis and management of gastroenteropancreatic neuroendocrine neoplasms.

World J Gastrointest Endosc 2022 May;14(5):267-290

Division of Gastroenterology Hepatology and Endoscopy, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, United States.

Gastroenteropancreatic neuroendocrine neoplasms are a heterogenous group of rare neoplasms that are increasingly being discovered, often incidentally, throughout the gastrointestinal tract with varying degrees of activity and malignant potential. Confusing nomenclature has added to the complexity of managing these lesions. The term carcinoid tumor and embryonic classification have been replaced with gastroenteropancreatic neuroendocrine neoplasm, which includes gastrointestinal neuroendocrine and pancreatic neuroendocrine neoplasms.

Multimodal data analysis reveals that pancreatobiliary-type ampullary adenocarcinoma resembles pancreatic adenocarcinoma and differs from cholangiocarcinoma.

J Transl Med 2022 Jun 15;20(1):272. Epub 2022 Jun 15.

Department of Pancreatobiliary Surgery, Sun Yat-Sen University Cancer Center, Guangzhou, China.

Background: Ampullary adenocarcinoma (AAC) arises from the ampulla of Vater where the pancreatic duct and bile duct join and empty into the duodenum. It can be classified into intestinal and pancreatobiliary types based on histopathology or immunohistochemistry. However, there are no biomarkers for further classification of pancreatobiliary-type AAC which has important implications for its treatment. Read More

[Differentiated Strategies for the Therapy of Liver Metastases in Gastro-entero-pancreatic Neuroendocrine Neoplasia].

Zentralbl Chir 2022 Jun 15;147(3):270-280. Epub 2022 Jun 15.

Chirurgische Klinik Campus Charité Mitte | Campus Virchow-Klinikum, Charité Universitätsmedizin Berlin, Berlin, Deutschland.

Neuroendocrine neoplasias comprise a heterogenous group of malignant tumours, mostly arising from the gastro-entero-pancreatic system (GEP). Most of these tumours develop from the small intestine and pancreas and the liver is the predominant site for distant metastases. Patients may be asymptomatic for a long time and liver metastases are frequently diagnosed by chance or during operations for bowel obstruction, for example, during emergency surgery. Read More

Vitamin D receptor absence does not enhance intestinal tumorigenesis in ApcPirc/+ rats.

Biol Open 2022 Jun 6. Epub 2022 Jun 6.

Department of Biochemistry, University of Wisconsin-Madison, 433 Babcock Drive, Madison, WI 53706, USA.

Epidemiological observations have prompted some to posit that elevated circulating vitamin D is responsible for reduced colon cancer in individuals residing near the equator. We have previously demonstrated that vitamin D has no effect on colon cancer in two rodent models of intestinal tumorigenesis. We have now extended this line of inquiry to ask whether ablation of vitamin D receptor (VDR) affects tumorigenesis. Read More

The Prognostic Relevance of Preoperative CEA and CA19-9 for Ampulla of Vater Carcinoma.

Anticancer Res 2022 Jun;42(6):3169-3176

Division of Hepato-Biliary-Pancreatic Surgery, Shizuoka Cancer Center, Shizuoka, Japan.

Background/aim: Increased serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA19-9) are established prognostic factors in ampulla of Vater carcinoma (AC). We determined the best cut-off values of preoperative CEA and CA19-9 and compared the prognostic power of preoperative CEA with that of preoperative CA19-9 for overall survival (OS).

A case of a mature anterior mediastinal teratoma with a predominance of the pancreatic component (80% of the tumor) and signs of nesidioblastosis in a 46-year-old woman is presented. During histological examination, all components of the pancreatic parenchyma were determined - acini with interlobular and intralobular ducts, endocrine cells and islets of Langerhans of various sizes and shapes, as well as islet-duct complexes scattered in the acinar tissue. In addition to pancreatic tissue, cartilage, bronchial respiratory epithelium, small intestine tissue, hair follicles, and sebaceous glands were found in the neoplasm. Read More

Zhonghua Wei Chang Wai Ke Za Zhi 2022 May;25(5):378-384

Department of General Surgery, The Second Affiliated Hospital, Air Force Medical University, Xi'an 710038, China.

With the development of instrument, equipment and surgical skills, especially the emergence of a series of high-level medical evidence, the laparoscopic techniques in the field of gastric surgery has been further expanded. Totally laparoscopic total gastrectomy (TLTG) has certain technical difficulties, and more challenges are reflected in the digestive tract reconstruction. The use of linear staplers has reduced the difficulty of digestive tract reconstruction to a certain extent and has strongly promoted the transition from laparoscopic-assisted total gastrectomy to TLTG.

Department of General Surgery, The First Affiliated Hospital, Nanjing Medical University, Nanjing 210029, China.

Laparoscopic techniques are more and more poplular in proximal gastrectomy. The traditional esophagogastric anastomosis may lead to severe reflux esophagitis after surgery, affecting patient's quality of life. In recent years, multiple methods of digestive tract reconstruction after laparoscopic proximal gastrectomy capable of resisting reflux have been applied to the clinic. Read More

Influence of Pholiota adiposa on gut microbiota and promote tumor cell apoptosis properties in H22 tumor-bearing mice.

Sci Rep 2022 May 21;12(1):8589. Epub 2022 May 21.

Academy of Medical, Changchun Sci-Tech University, Changchun, China.

Hepatocellular carcinoma (HCC) is a common type of cancer-prevalent worldwide-and one of the causes of cancer-related deaths. In this study, ethanol extracts from Pholiota adiposa (EPA) were used to identify possible targets for HCC treatment and their effects on intestinal microflora were analyzed. Methods: Male mice were randomly assigned to groups-the model group, cyclophosphamide (25 mg/kg/d), and EPA groups, in which the mice were categorized based on the different concentrations of each compound (100, 200, and 300 mg/kg/day).
