Neuroendocrine tumors of the thymus [PDF]

Journal of Thoracic Disease, 2017
Primary neuroendocrine tumors of the thymus (NETTs) are rare and biologically very aggressive neoplasms, usually located in the anterior mediastinal space. They are more frequently observed in males, in their fourth/fifth decades of life. In 50% of cases, NETTs are associated with endocrinopaties [Cushing's syndrome, acromegaly or Multiple Endocrine ...

Current treatment strategies for patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs)

Clinical Diabetes and Endocrinology, 2018
Background Neuroendocrine tumors (NETs) are rare neoplasms, with an estimated annual incidence of ~ 6.9/100,000. NETs arise throughout the body from cells of the diffuse endocrine system.

Dosimetry after peptide receptor radionuclide therapy: impact of reduced number of post-treatment studies on absorbed dose calculation and on patient management

EJNMMI Physics, 2020
Background After each cycle of [177Lu]-DOTA-TATE peptide receptor radionuclide therapy (PRRT) dosimetry is performed to enable precise calculation of the radiation-absorbed dose to tumors and normal organs.

Expression of a neuroendocrine gene signature in gastric tumor cells from CEA 424-SV40 large T antigen-transgenic mice depends on SV40 large T antigen. [PDF]

PLoS ONE, 2012
BackgroundA large fraction of murine tumors induced by transgenic expression of SV40 large T antigen (SV40 TAg) exhibits a neuroendocrine phenotype. It is unclear whether SV40 TAg induces the neuroendocrine phenotype by preferential transformation of ...

Hitherto unseen survival in an ALK‐positive‐patient with advanced stage adult ganglioneuroblastoma treated with personalized medicine

Clinical Case Reports, 2017
Key Clinical Message Survival of stage 4 ganglioneuroblastoma (GNB) patients is poor; no reports exist of patients surviving up to 5 years (1, 2). We report the clinical and therapeutic course of a patient with stage 4 GNB surviving beyond expectations ...

Emerging role of substance and energy metabolism associated with neuroendocrine regulation in tumor cells

Frontiers in Endocrinology, 2023
Cancer is the second most common cause of mortality in the world. One of the unresolved difficult pathological mechanism issues in malignant tumors is the imbalance of substance and energy metabolism of tumor cells.

Ghrelin in neuroendocrine tumors [PDF]

Peptides, 2011
Ghrelin is a 28 amino acid peptide, primarily produced by the oxyntic mucosa X/A like neuroendocrine cells in the stomach. It is also found in the small intestine, hypothalamus, pituitary gland, pancreas, heart, adipose tissue, and immune system. In gastrointestinal neuroendocrine tumors (NETs) ghrelin release has been well documented.
