Neuroendocrine tumors (NETs) of the gastrointestinal (GI) tract have a propensity for producing hepatic metastases. Most GI NETs arise from the foregut or midgut, are malignant, and can cause severe…
Pancreatic neuroendocrine tumors (PNETs) are uncommon tumors with a range of clinical behavior. Some PNETs are associated with symptoms of hormone secretion, with increased systemic levels of insulin, gastrin, glucagon,…
Neuroendocrine tumors (NETs) are rare epithelial neoplasms with neuroendocrine differentiation originating most commonly in the lungs and gastroenteropancreatic. Treatment includes surgery and other local therapies; treatment of inoperable disease centers…
Poorly differentiated neuroendocrine carcinomas of the gastrointestinal tract are rare and limited data are available to guide treatment. These tumors have been treated akin to small cell lung cancer given…
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare but unique neuroendocrine tumors. The hypersecretion of catecholamines from the tumors can be associated with high morbidity and mortality, even when tumors are…
Pancreatic neuroendocrine tumors are an uncommon tumor type and compose 1% to 2% of all pancreatic neoplasms. They are rarely localized at presentation and are typically diagnosed in the presence…
Bronchial and thymic carcinoids are rare. We present epidemiologic data and potential risk factors. The approach to bronchial and thymic carcinoid patients is discussed, from the initial diagnosis and evaluations…
Well-differentiated gastrointestinal neuroendocrine tumors (GINETs) tend to be slow growing, but treatment of advanced disease remains a challenge. Somatostatin analogues (SSAs) are considered standard therapy for carcinoid syndrome. SSAs delay…
Neuroendocrine tumors (NETs) are slow-growing neoplasms capable of storing and secreting different peptides and neuroamines. Some of these substances cause specific symptom complexes, whereas others are silent. They usually have…
Neuroendocrine tumors of the small bowel are rare, slow-growing malignancies that commonly metastasize to nodes at the root of the mesentery and the liver. Liver metastases are associated with carcinoid…
