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.

Clin Med Res 2018 06 12;16(1-2):16-28. Epub 2018 Apr 12.

University of Central Florida College of Medicine/HCA Consortium Graduate Medical Education, North Florida Regional Medical Center, 6500 W Newberry Rd, Gainesville, FL 32605.

Flushing is the subjective sensation of warmth accompanied by visible cutaneous erythema occurring throughout the body with a predilection for the face, neck, pinnae, and upper trunk where the skin is thinnest and cutaneous vessels are superficially located and in greatest numbers. Flushing can be present in either a wet or dry form depending upon whether neural-mediated mechanisms are involved. Activation of the sympathetic nervous system results in wet flushing, accompanied by diaphoresis, due to concomitant stimulation of eccrine sweat glands. Read More

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

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

Purpose: Neuroendocrine tumors (NETs) are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung, ovary, and thyroid glands. They can be well differentiated or poorly differentiated, and management of these tumors differs for each histologic subtype. We have performed a review of NETs and focused on management of well-differentiated gastroenteropancreatic neuroendocrine tumors (GEPNETs) and carcinoid syndrome. Read More

Composite intestinal adenoma-microcarcinoid in the colon and rectum: a case series and historical review.

Diagn Pathol 2017 Nov 7;12(1):78. Epub 2017 Nov 7.

Department of Pathology, University of Inje College of Medicine, Sanggye Paik hospital, Dongil-ro 1342, Nowon-gu, Seoul, Republic of Korea.

Background: Composite intestinal adenoma-microcarcinoid (CIAM) is a rare colorectal lesion that mostly comprises a conventional adenomatous component with a minute proportion of neuroendocrine (NE) component. Although microcarcinoids are well-recognized in the setting of chronic inflammatory disorders of the gastrointestinal tract, large intestinal microcarcinoids associated with intestinal adenoma are exceedingly rare and their clinicopathologic characteristics are yet to be elucidated. This study was performed to clarify their clinicopathologic characteristics and to review the relevant literature. Read More

Echocardiography in functional midgut neuroendocrine tumors: When and how often.

Rev Endocr Metab Disord 2017 Dec;18(4):411-421

Department of Cardiovascular Surgery, Mount Sinai Health System, The Mount Sinai Hospital, 1190 Fifth Avenue, GP2 West, New York, NY, 10029-6574, USA.

The management of patients with midgut neuroendocrine tumors (MNET) is rapidly evolving. Current preoperative detection rates of primary tumor sites are higher than ever and progression-free survival in patients with already advanced disease is expanding due to the implementation of novel efficacious treatment strategies. This survival benefit may potentially translate into a need for a multidisciplinary approach to an even more heterogenous variety of clinical conditions, among these, carcinoid syndrome (CS) and carcinoid heart disease (CHD).

A 17-year-old male with a Small Bowel Neuroendocrine Tumor: flushing differential diagnosis.

World Allergy Organ J 2017 4;10(1):30. Epub 2017 Sep 4.

Faculty of Medicine, Universidad de los Andes, Bogotá, Colombia.

Background: Neuroendocrine tumors (NETs) are heterogeneous neoplasms that originate from cells with a secretory function. Small bowel NETs (SB-NETs) are related to serotonin hypersecretion which causes: flushing, diarrhea, abdominal pain, bronchoconstriction and heart involvement, also known as carcinoid syndrome (CS). CS can be confused with an allergic reaction and thus should be considered as a differential diagnosis in the allergy consult. Read More

The Advantage of an Endoscopic Submucosal Tunneling Technique for Rectal Carcinoid Tumors.

Gut Liver 2017 Sep;11(5):735-737

Department of Gastroenterology and Neurology, Kagawa University Faculty of Medicine, Kagawa, Japan.

Endoscopic treatment can be a curative option for small carcinoid tumors with an extremely low risk of metastasis. Since most carcinoid tumors are characterized by a specific growth pattern in the submucosal (SM) layer, specialized endoscopic techniques for deeper resection to achieve clear vertical margins are needed. The endoscopic submucosal dissection (ESD) method in the SM space is superior to conventional endoscopic mucosal resection. Read More

Fatal Systemic Vasoconstriction in a Case of Metastatic Small-Intestinal NET.

Case Rep Gastrointest Med 2017 18;2017:9810194. Epub 2017 Jul 18.

Department of Clinical Toxicology, Klinikum rechts der Isar, Technical University of Munich, Ismaningerstrasse 22, 81675 Munich, Germany.

An increased release of serotonin secreted by ileal NETs is thought to be the major factor causing the carcinoid syndrome. However, in acutely arising carcinoid crisis also other vasoactive factors may lead to hazardous fluctuations in blood pressure and bronchial constriction. In rare cases, systemic vasoconstriction can be observed, probably caused by catecholamines or similar acting substances. Read More
