Long Non-coding RNAs in Pulmonary Neuroendocrine Neoplasms.

Endocr Pathol 2020 May 9. Epub 2020 May 9.

Department of Pathology and Laboratory Medicine, University of Wisconsin School of Medicine and Public Health, 600 Highland Avenue, Madison, WI, 53792-8550, USA.

Pulmonary neuroendocrine neoplasms (NENs) are classified into low-grade neuroendocrine tumors and high-grade neuroendocrine carcinomas (NECs). There are significant differences in therapeutic strategies of the different NEN subtypes, and therefore, precise classification of pulmonary NENs is critical. However, challenges in pulmonary NEN classification include overlap of diagnostic histological features among the subtypes and reduced or negative expression of neuroendocrine markers in poorly differentiated pulmonary NECs.

Hereditary Syndromes in Neuroendocrine Tumors.

Authors:
Mark A Lewis

Curr Treat Options Oncol 2020 Apr 30;21(6):50. Epub 2020 Apr 30.

Gastrointestinal Oncology, Intermountain Healthcare, 5171 S. Cottonwood Street, Bldg. 1. Ste. 610, Murray, UT, 84107, USA.

Opinion Statement: Oncologists should be able to discern the salient clinical features of the most common germline mutations that give rise to neuroendocrine tumors. Astute recognition of an index patient affected by a hereditary syndrome can lead to a "tip-of-the-iceberg" phenomenon whereby their entire kindred can then be proactively monitored and managed potentially with substantial reduction of morbidity and mortality. Through careful history-taking, as well as thoughtful assimilation of findings from the physical exam, biochemical laboratories, scans, and pathology reports, the clinician can spot phenotypic clues that distinguish these familial patterns from sporadic cases of tumorigenesis.

Centromeric cohesion failure invokes a conserved choreography of chromosomal mis-segregations in pancreatic neuroendocrine tumor.

Genome Med 2020 Apr 28;12(1):38. Epub 2020 Apr 28.

Department of Medical Biophysics, University of Toronto, Toronto, Ontario, Canada.

Background: Pancreatic neuroendocrine tumors (PANETs) are rare, slow growing cancers that often present with local and distant metastasis upon detection. PANETS contain distinct karyotypes, epigenetic dysregulation, and recurrent mutations in MEN1, ATRX, and DAXX (MAD+); however, the molecular basis of disease progression remains uncharacterized.

Methods: We evaluated associations between aneuploidy and the MAD+ mutational state of 532 PANETs from 11 published genomic studies and 19 new cases using a combination of exome, targeted panel, shallow WGS, or RNA-seq. Read More

Transcriptomic data helps refining classification of pulmonary carcinoid tumors with increased mitotic counts.

Mod Pathol 2020 Apr 14. Epub 2020 Apr 14.

Quebec Heart and Lung Institute Research Center, Quebec City, QC, Canada.

Pulmonary neuroendocrine neoplasms are classified by WHO as either typical or atypical carcinoids, large cell (LCNEC) or small cell (SCLC) neuroendocrine carcinoma based on mitotic count, morphology, and necrosis assessment. LCNEC with low mitotic count and sharing morphologic features with carcinoids are in a gray zone for classification and their rare prevalence and the paucity of studies precludes proper validation of the current grading system. In this study, we aim to investigate their clinicopathological and transcriptomic profiles. Read More

A primary neuroendocrine tumor of the left ventricle presenting with diarrhea-an unusual experience and literature review.

Diagn Pathol 2020 Apr 3;15(1):32. Epub 2020 Apr 3.

Department of Pathology, The Affiliated Hospital of Zunyi Medical University, Zunyi, 563000, Guizhou, China.

Background: Neuroendocrine tumors (NETs) can secrete bioactive amines in the bloodstream, resulting in the carcinoid syndrome characterized by diarrhea and flushing. The frequency of occurrence of primary cardiac neuroendocrine neoplasms is lesser than that of metastases, and hence, metastases must be adequately ruled out before diagnosis. Cardiac tumors, both primary and metastatic, mainly result in heart-related symptoms, such as heart failure and acquired valvular dysfunction. Read More

Division of Chest Surgery, Department of Surgery, School of Medicine, Toho University, 6-11-1, Omori-Nishi, Ota-ku, Tokyo, 143-8541, Japan.

In 1970, neuroendocrine tumors of the lung were classified into three categories: typical carcinoid (TC), atypical carcinoid (AC), and small cell lung carcinoma (SCLC). The third edition of the World Health Organization (WHO) classification in 1999 defined large cell neuroendocrine carcinoma (LCNEC) as a variant of large cell carcinomas, whereas the fourth edition of the WHO classification redefined LCNEC as a neuroendocrine tumor. Currently, neuroendocrine tumors of the lung are classified into four main categories: TC, AC, LCNEC, and SCLC. Read More

Although there are reports of goblet cell carcinoid(GCC)treated by chemotherapy using the treatment protocol for colon cancer, the benefit of chemotherapy for GCC remains controversial and unclear. Herein we report 2 cases of patients with GCC who were successfully treated by surgical resection and oxaliplatin-based adjuvant chemotherapy, without evidence of recurrence. The first case was a 57-year-old man who underwent laparoscopic ileocecal resection after being diagnosed with adenocarcinoma of the appendix by biopsy via colonoscopy. Read More

Colonic Goblet Cell Carcinoid: Rarity of a Rarity! A Case Report and Review of Literature.

Chirurgia (Bucur) 2020 Jan-Feb;115(1):102-111

Goblet cell carcinoids (GCC) are extremelyrare neuroendocrine tumours, and characterised by their unique combination of two types of cancer cells âÃÂ" neuroendocrine (carcinoid) and epithelial (adeno-carcinoma). In spite of the fact that GCC is regarded as Neuro-Endocrine Tumour (NET), it does not illicit carcinoid syndrome. GCC usually arises in the appendix and accounting for less than 14% of all appendiceal tumours. Read More

Neuroendocrine neoplasms of the colon and rectum are rare, although surgeons are likely to encounter appendiceal neuroendocrine tumors while caring for patients with appendicitis. Surgery remains the primary treatment, provided disease is resectable, although for small rectal lesions endoscopic resection is often sufficient. Metastastic disease has a variety of treatment options. Read More

Management of Other Gastric and Duodenal Neuroendocrine Tumors.

Surg Oncol Clin N Am 2020 Apr;29(2):253-266

Section of Endocrine Surgery, Rutgers Cancer Institute of New Jersey, Rutgers Robert Wood Johnson Medical School, 195 Little Albany Street, New Brunswick, NJ 08903, USA.

Gastric and duodenal neuroendocrine tumors (NETs) are increasing in incidence as a result of increased detection and awareness of neuroendocrine tumors as distinct tumor types. The three types of gastric NETs and duodenal NETs have different etiologies and tumor-specific factors, such as grade, location, and hormone-production, and the clinical settings influence management. Options for treatment include removal by local endoscopic resection and surgical resection. Read More

Management of Small Bowel Neuroendocrine Tumors.

Surg Oncol Clin N Am 2020 Apr;29(2):223-241

Department of Surgery, University of Iowa Carver College of Medicine, Iowa City, IA, USA; Division of Surgical Oncology and Endocrine Surgery, University of Iowa Carver College of Medicine, Iowa City, IA, USA. Electronic address:

Small bowel neuroendocrine tumors (SBNETS) are slow-growing neoplasms with a noted propensity toward metastasis and comparatively favorable prognosis. The presentation of SBNETs is varied, although abdominal pain and obstructive symptoms are the most common presenting symptoms. In patients with metastases, hypersecretion of serotonin and other bioactive amines results in diarrhea, flushing, valvular heart disease, and bronchospasm, termed carcinoid syndrome. Read More

Radiographic characteristics of neuroendocrine liver metastases do not predict clinical outcomes following liver resection.

Hepatobiliary Surg Nutr 2020 Feb;9(1):1-12

Department of Surgery, Division of Surgical Oncology, The Ohio State University Wexner Medical Center, Columbus, OH, USA.

Background: Previous research has demonstrated that specific radiographic criteria, including the presence of calcifications and the enhancement pattern on computed tomography (CT) imaging, correlates with clinicopathologic features and outcomes of patients with gastroenteropancreatic neuroendocrine tumors (NET). We sought to investigate whether these radiographic characteristics were prognostic among patients with neuroendocrine liver metastases (NELM) undergoing surgical resection.

Methods: The preoperative contrast-enhanced CT scans of all patients who underwent resection of NELM at a single institution between 2000-2015 were retrospectively reviewed. Read More

Somatostatin Analogs in Clinical Practice: a Review.

Int J Mol Sci 2020 Feb 29;21(5). Epub 2020 Feb 29.

Department of Endocrinology, "La Paz" University Hospital. Paseo de la Castellana, 261, 28046 Madrid, Spain.

Somatostatin analogs are an invaluable therapeutic option in the diagnosis and treatment of somatotropinomas, thyrotropinomas, and functioning and non-functioning gastroenteropancreatic neuroendocrine tumors. They should also be considered an effective and safe therapeutic alternative to corticotropinomas, gonadotropinomas, and prolactinomas resistant to dopamine agonists. Somatostatin analogs have also shown to be useful in the treatment of other endocrine diseases (congenital hyperinsulinism, Graves' orbitopathy, diabetic retinopathy, diabetic macular edema), non-endocrine tumors (breast, colon, prostate, lung, and hepatocellular), and digestive diseases (chronic refractory diarrhea, hepatorenal polycystosis, gastrointestinal hemorrhage, dumping syndrome, and intestinal fistula).
