    [Surgical strategies for small sporadic neuroendocrine pancreatic tumors].
    Chirurg 2018 Apr 10. Epub 2018 Apr 10.
    Sektionsleitung Endokrine Chirurgie, Klinik für Viszeral‑, Thorax- und Gefäßchirurgie, Universitätsklinikum Marburg, Baldingerstraße, 35043, Marburg, Deutschland.
    Small (<2 cm) sporadic neuroendocrine pancreatic neoplasms (pNENs) are a heterogeneous group of neoplasms, which can be separated into functionally active or non-functional tumors. Functionally active pNENs release various hormones, such as insulin, gastrin, glucagon and vasoactive intestinal hormones and therefore lead to severe symptoms independent of their size. The main symptoms include hypoglycemia, coma (insulinoma), diarrhea (gastrinoma, VIPoma), intestinal ulcers (gastrinoma) and hyperglycemia (glucagonoma). Read More

    Surgical resection of neuroendocrine tumors of the pancreas (pNETs) by minimally invasive surgery: the laparoscopic approach.
    Gland Surg 2018 Feb;7(1):12-19
    Department of Gastrointestinal and Pediatric Surgery, Tokyo Medical University, Tokyo, Japan.
    Neuroendocrine tumors of the pancreas (pNETs) are a rare group of neoplasms that originate from the endocrine portion of the pancreas. Tumors that either secrete or do not secrete compounds, resulting in symptoms, can be classified as functioning and non-functioning pNETs, respectively. The prevalence of such tumors has recently increased due to the use of more sensitive imaging techniques, such as multidetector computed tomography, magnetic resonance imaging and endoscopic ultrasound.

    Second malignancies in patients with myeloproliferative neoplasms: a population-based cohort study of 9379 patients.
    Leukemia 2018 Jan 30. Epub 2018 Jan 30.
    Department of Medicine, Division of Hematology, Karolinska University Hospital and Karolinska Institutet, Stockholm, Sweden.
    To determine the risk of a wide range of second malignancies in patients with myeloproliferative neoplasms (MPNs), we conducted a large population-based study and compared the results to matched controls. From national Swedish registers, 9379 patients with MPNs diagnosed between 1973 and 2009, and 35,682 matched controls were identified as well as information on second malignancies, with follow-up until 2010. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated using Cox regression and a flexible parametric model. Read More

    Predictive factors of endocrine and exocrine insufficiency after resection of a benign tumour of the pancreas.
    Ann Endocrinol (Paris) 2018 Apr 8;79(2):53-61. Epub 2018 Mar 8.
    CHU de Poitiers, service de chirurgie viscérale, 2, rue de la Milétrie, 86000 Poitiers, France.
    Background: The aim of the present study is to evaluate the risk factors of endocrine and exocrine insufficiency occurring few years after pancreatic resections in a consecutive series of patients who underwent pancreatoduodenectomy (PD), left pancreatectomy (LP) or enucleation for benign neoplasms at a referral centre.

    Methods: Pancreatic exocrine insufficiency (PEI) was defined by the onset of steatorrhea associated with weight loss, and endocrine insufficiency was determinate by fasting plasma glucose. Association between pancreatic insufficiency and clinical, pathological, and perioperative features was studied using univariate and multivariate Cox regression analysis. Read More

We review the literature of gene mutations in thyroid, parathyroid, pituitary, pineal gland, endocrine pancreas, paragangliomas, medullary, adrenocortical, ovarian and testicular tumors. Read More

    Common genetic variants associated with pancreatic adenocarcinoma may also modify risk of pancreatic neuroendocrine neoplasms.
    Carcinogenesis 2018 Mar;39(3):360-367
    Genomic Epidemiology Group, German Cancer Research Centre (DKFZ), Heidelberg, Germany.
    Pancreatic neuroendocrine neoplasms (pNEN) account for less than 5% of all pancreatic neoplasms and genetic association studies on susceptibility to the disease are limited. We sought to identify possible overlap of genetic susceptibility loci between pancreatic ductal adenocarcinoma (PDAC) and pNEN; therefore, PDAC susceptibility variants (n = 23) from Caucasian genome-wide association studies (GWAS) were genotyped in 369 pNEN cases and 3277 controls from the PANcreatic Disease ReseArch (PANDoRA) consortium to evaluate the odds associated with pNEN risk, disease onset and tumor characteristics. Main effect analyses showed four PDAC susceptibility variants-rs9854771, rs1561927, rs9543325 and rs10919791 to be associated with pNEN risk. Read More

    Neuroendocrine Neoplasms: Dichotomy, Origin and Classifications.
    Visc Med 2017 Oct 16;33(5):324-330. Epub 2017 Oct 16.
    Consultation Center for Pancreatic and Endocrine Tumors, Institute of Pathology, Technical University München, Munich, Germany.
    Neuroendocrine neoplasms (NENs) are heterogeneous tumors with a common phenotype. There are two fundamentally different groups of NENs: well-differentiated, low-proliferating NENs, called neuroendocrine tumors (NETs) or carcinoids, and poorly differentiated, highly proliferating NENs, called small- or large-cell neuroendocrine carcinomas (NECs). This NEN dichotomy is probably due to an origin from different neuroendocrine progenitor cells. Read More

    Ki67 labeling index: assessment and prognostic role in gastroenteropancreatic neuroendocrine neoplasms.
    Virchows Arch 2018 Mar 13;472(3):341-349. Epub 2017 Nov 13.
    Service of Clinical Pathology, Institute of Pathology, Lausanne University Hospital, Lausanne, Switzerland.
    In 1983, a monoclonal antibody, Ki67, was generated, that labeled the nuclei of proliferating non-neoplastic and neoplastic cells. The name Ki67 derived from the city of Kiel (Ki) where the antibody was produced in the university department of pathology and refers to the number of the original clone (67). Systematic assessment of the proliferative activity of tumors using Ki67 started in the 1990s, when Ki67, which only worked on frozen tissue, was complemented by the antibody MIB-1 that also worked in formalin-fixed tissues.

    Insights into beta cell regeneration for diabetes via integration of molecular landscapes in human insulinomas.
    Nat Commun 2017 10 3;8(1):767. Epub 2017 Oct 3.
    The Diabetes Obesity and Metabolism Institute, The Icahn School of Medicine at Mount Sinai, New York, NY, 10029, USA.
    Although diabetes results in part from a deficiency of normal pancreatic beta cells, inducing human beta cells to regenerate is difficult. Reasoning that insulinomas hold the "genomic recipe" for beta cell expansion, we surveyed 38 human insulinomas to obtain insights into therapeutic pathways for beta cell regeneration. An integrative analysis of whole-exome and RNA-sequencing data was employed to extensively characterize the genomic and molecular landscape of insulinomas relative to normal beta cells. Read More

    Genetic analysis of parathyroid and pancreatic tumors in a patient with multiple endocrine neoplasia type 1 using whole-exome sequencing.

    Angiotensin II Causes β-Cell Dysfunction Through an ER Stress-Induced Proinflammatory Response.
    Endocrinology 2017 10;158(10):3162-3173
    School of Health and Biomedical Sciences, Royal Melbourne Institute of Technology University, Bundoora, Victoria 3083, Australia.
    The metabolic syndrome is associated with an increase in the activation of the renin angiotensin system, whose inhibition reduces the incidence of new-onset diabetes. Importantly, angiotensin II (AngII), independently of its vasoconstrictor action, causes β-cell inflammation and dysfunction, which may be an early step in the development of type 2 diabetes. The aim of this study was to determine how AngII causes β-cell dysfunction. Read More

    [Multiple endocrine neoplasia].
    Dtsch Med Wochenschr 2017 Sep 8;142(18):1379-1389. Epub 2017 Sep 8.

    Department of Radiology, UMass Memorial Medical Center, University of Massachusetts Medical School, 55 Lake Avenue North, Worcester, MA 01655, USA. Electronic address:
    Imaging of the endocrine pancreas is dominated by neuroendocrine tumors, a diverse category of neoplasms that may or may not cause symptoms from hormone hypersecretion. These tumors may also be evidence of several different genetic syndromes. Understanding the usefulness of different imaging modalities and entities that simulate neuroendocrine tumors is key for both radiologists and referring physicians. Read More

    Perioperative management of endocrine insufficiency after total pancreatectomy for neoplasia.
    Langenbecks Arch Surg 2017 Sep 21;402(6):873-883. Epub 2017 Jul 21.
    Department of Medicine, Division of Endocrinology, University of Illinois at Chicago and Creticos Cancer Center at Advocate Illinois Masonic Medical Center, Chicago, IL, USA.
    Purpose: Indications for total pancreatectomy (TP) have increased, including for diffuse main duct intrapapillary mucinous neoplasms of the pancreas and malignancy; therefore, the need persists for surgeons to develop appropriate endocrine post-operative management strategies. The brittle diabetes after TP differs from type 1/2 diabetes in that patients have absolute deficiency of insulin and functional glucagon. This makes glucose management challenging, complicates recovery, and predisposes to hospital readmissions. Read More

    Department of Gastroenterology, Staten Island University Hospital.
    Solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor that accounts for less than one percent of pancreatic tumors. The diagnosis could be challenging as SPN tend to manifest with nonspecific abdominal symptoms, variable radiological features, and inconsistent morphology. The cellular origin of SPN is unclear and might involve ductal, acinar and endocrine stem cells. Read More

    A partial pancreaticogastrodudenectomy was performed on a 66-year old man with type 2 diabetes mellitus because of an invasive, moderately differentiated adenocarcinoma in the head of the pancreas. In the adjacent grossly normal tissue of the uncinate process, there was a massive proliferation of pancreatic polypeptide (PP) cells confined to this region and showed invasive pattern. Strikingly, in the heaped area of his duodenum, there was a strikingly large number of PP, glucagon, a few insulin cells in a mini-islet-like patterns composed of glucagon and insulin cells.

    Human induced pluripotent stem cells (hiPSCs) may provide potential resource for regenerative medicine research, including generation of insulin-producing cells for diabetes research and insulin production. Testosterone (T) is an androgen hormone which promotes protein synthesis and improves the management of type 2 diabetes in clinical studies. Concurrently, co-existed hyperandrogenism and hyperinsulinism is frequently observed in polycystic ovary syndrome, congenital adrenal hyperplasia and some of Wermer's syndrome. Read More

    Pancreatic neuroendocrine neoplasms (PNENs) represent 10% of all pancreatic tumors by prevalence. Their incidence has reportedly increased over recent decades in parallel with that of pancreatic adenocarcinoma. PNENs are relatively rare, and of the few institutions that have published potential risk factors, findings have been heterogeneous. Read More
