Dual-phase computed tomography angiography of intestinal carcinoid tumor as a lead point for cecocolic intussusception in a dog.

J Vet Med Sci 2019 Apr 17. Epub 2019 Apr 17.

College of Veterinary Medicine and BK 21 Plus Project Team, Chonnam National University.

In an 8-year-old Labrador Retriever with progressive anorexia, constipation, and depression, CT revealed intussusception of the cecum into the ascending colon and a small cecal mass showing strong enhancement on arterial phase. The ileocecocolic junction was surgically resected and histologically diagnosed as cecocolic intussusception with carcinoid tumor. The carcinoid tumor worked as a lead point of intussusception in this case. Read More

Vitamin D and vitamin B deficiencies in patients with small intestinal carcinoid tumour: is opioid use disorder a confounding factor in the diagnosis?

BMJ Case Rep 2019 Mar 16;12(3). Epub 2019 Mar 16.

Allama Iqbal Medical College, Lahore, Pakistan.

Carcinoid tumours have the ability to secrete various peptides and bioamines that lead to carcinoid syndrome manifested as cutaneous flushing, diarrhoea, bronchial constriction and cardiac involvement. The deficiencies of vitamins D and B have previously been reported in patients with carcinoid tumours presumably due to chronic diarrhoea associated with the carcinoid syndrome. Herein, we chronicle the case of a patient with opioid use disorder who presented with small bowel obstruction that was found to be caused by a midgut carcinoid tumour. Read More

Multifocal Small Bowel Carcinoid: Evaluation by 68Ga-DOTATATE PET.

Clin Nucl Med 2019 Apr;44(4):e308-e310

From the Department of Radiology, Division of Nuclear Medicine, Mayo Clinic, Rochester, MN.

Carcinoid is a subtype of neuroendocrine tumor, a rare group of tumors that are known to express somatostatin receptor 2. Ga-DOTATATE is a somatostatin analog that is specific for somatostatin receptor 2 and therefore allows visualization of neuroendocrine tumors. We present 2 cases of primary multifocal small bowel carcinoid evaluated using Ga-DOTATATE PET/CT, along with contrast-enhanced CT corollary findings. Read More

The safety of lanreotide for neuroendocrine tumor.

Expert Opin Drug Saf 2019 Jan 24;18(1):1-10. Epub 2018 Dec 24.

a Gastrointestinal Oncology Program and Experimental therapeutics, Division of Hematology/Oncology , Tufts Medical Center - Tufts University School of Medicine , Boston , MA , USA.

Introduction: Lanreotide autogel is a synthetic somatostatin analogue which has been FDA and EMA approved for unresectable, well to moderately differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumor. Its action is mediated by its affinity to somatostatin receptors, especially sst2 and sst5 receptors. Its longer half-life offers the convenience of 4-week dosing over the need for frequent injections of short-acting somatostatin analogues. Read More

Improved survival with higher doses of octreotide long-acting release in gastroenteropancreatic neuroendocrine tumors.

Med Oncol 2018 Aug 4;35(9):123. Epub 2018 Aug 4.

Department of Oncology, Tom Baker Cancer Centre, University of Calgary, 1331 29 St NW, Calgary, AB, T2N 4N2, Canada.

Gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) represent a heterogeneous group of tumors that is associated with an indolent course. Octreotide has a positive effect on disease stabilization in well-differentiated midgut NETs, but a meaningful survival analysis was not possible due to insufficient events. Higher doses of octreotide long-acting release (LAR) are often used in clinical practice for control of carcinoid symptoms and our objective was to determine if dose of octreotide correlates with survival.

A Case of Carcinoid Syndrome Due to Malignant Metastatic Carcinoid Tumor with Carcinoid Heart Disease Involving Four Cardiac Valves.

Am J Case Rep 2018 Mar 12;19:284-288. Epub 2018 Mar 12.

Department of Medicine, Krannert Institute of Cardiology, Indiana University School of Medicine, Indianapolis, IN, USA.

BACKGROUND Carcinoid tumor, benign, low-grade malignant, and high-grade malignant, can be associated with the release of vasoactive substances that cause symptoms including cutaneous flushing, diarrhea, and bronchospasm. In 50-60% of patients with carcinoid syndrome, the vasoactive substances cause fibrosis of the pulmonary and tricuspid heart valves which lead to regurgitation and right-sided heart failure. The right side of the heart is usually affected because monoamine oxidases in the lungs usually inactivate the vasoactive substances. Read More

Time-dependent transcriptional response of GOT1 human small intestine neuroendocrine tumor after Lu[Lu]-octreotate therapy.

Nucl Med Biol 2018 05 6;60:11-18. Epub 2018 Feb 6.

Department of Radiation Physics, Institute of Clinical Sciences, Sahlgrenska Cancer Center, Sahlgrenska Academy, University of Gothenburg, Sweden.

Introduction: Patients with neuroendocrine tumors expressing somatostatin receptors are often treated with Lu[Lu]-octreotate. Despite being highly effective in animal models, Lu[Lu]-octreotate-based therapies in the clinical setting can be optimized further. The aims of the study were to identify and elucidate possible optimization venues for Lu[Lu]-octreotate tumor therapy by characterizing transcriptional responses in the GOT1 small intestine neuroendocrine tumor model in nude mice.

Supportive therapy in gastroenteropancreatic neuroendocrine tumors: Often forgotten but important.

Rev Endocr Metab Disord 2018 06;19(2):145-158

Department of Internal Medicine IV, University-Hospital Campus Grosshadern, Ludwig-Maximilian University of Munich, Munich, Germany.

Neuroendocrine tumors (NETs) are a group of rare and heterogeneous malignancies that can develop in various organs. A significant number of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is functionally active and presents with symptoms related to the secretion of biologically active substances, leading to the development of distinct clinical syndromes. There are various therapeutic approaches for GEP-NETs, including curative surgery, palliative surgery, local-ablative and loco-regional therapies as well as systemic therapeutic options including peptide receptor radionuclide therapy, cytotoxic therapy, and molecularly targeted therapies.

Autoimmunity and Gastric Cancer.

Int J Mol Sci 2018 Jan 26;19(2). Epub 2018 Jan 26.

Immunologia e Allergologia, Presidio Ospedaliero S. Maria degli Angeli, 33170 Pordenone, Italy.

Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Read More

Appendiceal goblet cell carcinoids and adenocarcinomas ex-goblet cell carcinoid are genetically distinct from primary colorectal-type adenocarcinoma of the appendix.

Mod Pathol 2018 05 12;31(5):829-839. Epub 2018 Jan 12.

Institute of Pathology, Technical University of Munich, Munich, Germany.

The appendix gives rise to goblet cell carcinoids, which represent special carcinomas with distinct biological and histological features. Their genetic background and molecular relationship to colorectal adenocarcinoma is largely unknown. We therefore performed a next-generation sequencing analysis of 25 appendiceal carcinomas including 11 goblet cell carcinoids, 7 adenocarcinomas ex-goblet cell carcinoid, and 7 primary colorectal-type adenocarcinomas, using a modified Colorectal Cancer specific Panel comprising 32 genes linked to colorectal and neuroendocrine tumorigenesis.

[Adenocarcinoma in a Meckel's diverticulum with multiple liver metastases and gastrointestinal hemorrhage: a case report].

Beijing Da Xue Xue Bao Yi Xue Ban 2017 Dec;49(6):1095-1097

Department of Gastrointestinal Surgery, Peking University International Hospital, Beijing 102206, China.

Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, affecting approximately 2% of the population. It is a true diverticulum occurring on the anti-mesenteric border of the distalileum, typically within 100 cm of the ileo-caecal valve. Neoplasms arising in Meckel's diverticula are uncommon, and those reported in the literature are mainly carcinoid tumors, followed by gastrointestinal stromal tumors (GIST) and benign leiomyomas.

Fourth Surgical Department, Faculty of Health Science, School of Medicine, Aristotle University of Thessaloniki, "G. Papanikolaou" General Hospital, Thessaloniki 57010, Greece.

Neuroendocrine tumors represent a heterogeneous group of neoplasms that arise from neuroendocrine cells and secrete various peptides and bioamines. While gastrointestinal neuroendocrine tumors, commonly called carcinoids, account for about 2/3 of all neuroendocrine tumors, they are relatively rare. Small intestine neuroendocrine tumors originate from intestinal enterochromaffin cells and represent about 1/4 of small intestine neoplasms. Read More

Judy S Crabtree

Front Endocrinol (Lausanne) 2017 4;8:341. Epub 2017 Dec 4.

Department of Genetics, Louisiana State University Health Sciences Center, New Orleans, LA, United States.

The molecular events leading to gastroenteropancreatic neuroendocrine tumor (GEP-NET) formation are largely unknown. Over the past decades, systemic chemotherapies have been replaced by therapies directed at particular molecular targets such as the somatostatin receptors, mTOR complexes or proangiogenic molecules. These approaches have demonstrated some success in subtypes of this heterogeneous tumor group, but responses are still widely varied. Read More

Department of Internal MedicineSector Endocrinology, ENETS Centre of Excellence, Erasmus University Medical Center (Erasmus MC) and Erasmus MC Cancer Institute, Rotterdam, Netherlands.

Small intestinal neuroendocrine tumours (SI-NETs) are neoplasms characterized by their ability to secrete biogenic amines and peptides. These cause distinct clinical pathology including carcinoid syndrome, marked by diarrhoea and flushing, as well as fibrosis, notably mesenteric fibrosis. Mesenteric fibrosis often results in significant morbidity by causing intestinal obstruction, oedema and ischaemia. Read More
