This article reviews memory-related impairments in trauma survivors with posttraumatic stress disorder and their possible association to neuroendocrine alterations seen in this disorder. The neuroendocrine profile in PTSD first described in chronically ill combat veterans is characterized by lower basal cortisol levels, higher glucocorticoid receptor number, enhanced sensitivity to exogenous st...
Neuroendocrine tumors of the gastroenteropancreatic tract remain a difficult array of neoplasia to treat. Treatment of advanced and metastatic gastroenteropancreatic neuroendocrine tumors has traditionally been difficult with few systemic treatment options. In 2011, two new targeted therapies, everolimus and sunitinib were approved for treatment of pancreatic neuroendocrine tumor. The approval ...
Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are composed of cells with a neuroendocrine phenotype. The old and the new WHO classifications distinguish between well-differentiated and poorly differentiated neoplasms. All well-differentiated neoplasms, regardless of whether they behave benignly or develop metastases, will be called neuroendocrine tumours (NETs), and graded G1 (Ki67...
Neuroendocrine neoplasms of the larynx encompass five separate tumors: paraganglioma, typical carcinoid, atypical carcinoid, small cell carcinoma, and large cell neuroendocrine carcinoma. Many synonyms are employed, with well-, moderately, and poorly differentiated neuroendocrine carcinoma commonly applied to the middle three tumors (World Health Organization preferred terminology). Paraganglio...
BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are the most common type of neuroendocrine tumors, accounting for more than half of neuroendocrine neoplasms (NENs). We performed a retrospective study in our center to investigate the clinicopathological features, risk factors of metastasis, and prognosis of GEP-NENs in a Chinese population. METHODS Four hundred forty pati...
We encountered a rare case in which a 14 mm ampullary tumor had both components of neuroendocrine carcinoma and adenocarcinoma, which caused acute pancreatitis. A Sixty-one-year-old woman was referred to our hospital for evaluation and treatment of pancreatitis due to an unknown cause. After various imaging examinations, the cause of pancreatitis was found to be a duodenal papillary tumor. We p...
Part II of the guidelines contains a description of epidemiology, histopathology, clinical presentation, diagnostic procedure, treatment, and survival for each type of neuroendocrine tumour. We are not only including gastroenteropancreatic tumours but also bronchopulmonary and thymic neuroendocrine tumours. These guidelines essentially cover basic knowledge in the diagnosis and management of th...
To the Editor, Mixed endocrine glandular tumors of the gastrointestinal tract are rare lesions. In these tumors, the glandular and neuroendocrine components display a broad spectrum of combinations with marked variability in histopathology, immunohistochemical properties and clinical prognosis. We hereby report two cases of colonic tubulovillous adenomas, concomitantly containing a neuroendocri...
