Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

Carcinoid tumors are uncommon neoplasms of neuroendocrine origin that generally arise in the gastrointestinal or bronchopulmonary tracts and typically are characterized by an indolent clinical course. Metastases from these primary neoplasms more commonly affect the viscera, with rare reports of cutaneous metastases to the skin. We report the case of a patient with a cutaneous carcinoid metastasis that was incidentally brought to our attention because of the exquisite tenderness of the lesion. A brief review of the literature also is provided...

Sunitinib malate (sunitinib) is an orally available, multitargeted tyrosine kinase inhibitor with antitumor and antiangiogenic activities. Although sunitinib is effective for the treatment of patients with gastrointestinal stromal tumor, advanced renal cell carcinoma, or pancreatic neuroendocrine tumor, adverse cardiac events associated with sunitinib administration have been reported. Here, we examined the effect of geldanamycin, an inhibitor of heat shock protein (Hsp) 90, on sunitinib-induced cytotoxicity in cardiomyocytes...

Von Hippel-Lindau disease (vHL) is a hereditary tumor predisposition syndrome that places affected individuals at risk for multiple tumors, which are predominantly benign and generally occur in the central nervous system or abdomen. Although the majority of tumors occur in adults, children and adolescents with the condition develop a significant proportion of vHL manifestations and are vulnerable to delayed tumor detection and their sequelae. Although multiple tumor screening paradigms are currently being utilized for patients with vHL, surveillance should be reassessed as the available relevant clinical information continues to expand...

Neuroendocrine tumors comprise approximately 1-2% of all gastrointestinal tumors, and while the liver is the most common site for metastasis of these tumors, primary hepatic neuroendocrine tumors are very rare entities. Since first being reported in 1958, there have been less than 150 cases reported in the literature. Because of the infrequent occurrence of these tumors, the pool of data available for analysis regarding these tumors is small. As such, the medical community must rely on the publication of case report data to further enlarge this data pool, with the hopes of eventually having enough data to draw meaningful, statistically significant conclusions with regard to diagnosis and management of these rare tumors...

BACKGROUND: Previously we have proposed a modified European Neuroendocrine Tumor Society (mENETS) staging system for pNETs, which is more suitable than either the American Joint Committee on Cancer (AJCC) or the European Neuroendocrine Tumor Society (ENETS) systems. However, it is necessary to revise the nodal stage of the mENETS system for the under representation of stage III diseases. METHODS: Nodal substages of the upper gastrointestinal organs (N0: 0 node, N1: 1-2 nodes; N2: ≥3 nodes) or the lower gastrointestinal organs (0: 0 node, N1: 1-3 nodes, and N2:≥ 4 nodes) were incorporated into the mENETS system and evaluated using the Surveillance, Epidemiology, and End Results (SEER) registry series...

OBJECTIVES: The pharmacodynamic effects of everolimus on gastrointestinal hormone levels have not been described in patients with pancreatic neuroendocrine tumors (pNETs). We report the effects of everolimus on gastrin and glucagon levels in patients with progressive pNET in RADIANT-1 (a single-arm phase II trial) and RADIANT-3 (a placebo-controlled, randomized, phase III trial). METHODS: Serum gastrin and glucagon levels were determined by immunoassay at baseline and at predose in subsequent treatment cycles in patients with elevated baseline hormone levels...

There have been significant developments in diagnostic and therapeutic options for patients with neuroendocrine tumors (NETs). Key phase 3 studies include the CLARINET trial, which evaluated lanreotide in patients with nonfunctioning enteropancreatic NETs; the RADIANT-2 and RADIANT-4 studies, which evaluated everolimus in functioning and nonfunctioning NETs of the gastrointestinal tract and lungs; the TELESTAR study, which evaluated telotristat ethyl in patients with refractory carcinoid syndrome; and the NETTER-1 trial, which evaluated Lu-DOTATATE in NETs of the small intestine and proximal colon (midgut)...

Appendiceal neoplasms are uncommon tumors of the gastrointestinal tract that may manifest with symptoms of appendicitis, right lower quadrant pain, or palpable mass, leading to imaging or surgical intervention. The majority of appendiceal masses consist of primary epithelial neoplasms and neuroendocrine tumors (NETs). Epithelial neoplasms-mucinous and nonmucinous types-are more often detected at imaging than NETs due to their larger size and propensity for peritoneal spread and metastatic disease. Epithelial mucinous neoplasms are defined by the presence of mucin, detected at radiologic and pathologic examination...

Vladimir Neychev, Electron Kebebew
Our understanding of the biology, genetics, and natural history of neuroendocrine tumors (NETs) of the gastrointestinal tract and pancreas has improved considerably in the last several decades and the spectrum of available therapeutic options is rapidly expanding. The management of patients with metastatic low or intermediate grade NETs has been revolutionized by the development of new treatment strategies such as molecular targeting therapies with everolimus and sunitinib, somatostatin analogs, tryptophan hydroxylase inhibitors, and peptide receptor radionuclide therapy that can be used alone or as a multimodal approach with or without surgery...

Background: Detailed information regarding the clinical efficacy of radiotherapy (RT) for primary tumor in patients with unresectable pancreatic neuroendocrine tumors (pNETs) is unknown. We therefore performed a retrospective study to evaluate the efficacy and safety of RT for primary pancreatic tumors in patients with pNETs. Methods: We investigated 11 patients with pNETs who received RT to the primary site between January 1997 and June 2015. Seven patients had Grade 2 neuroendocrine tumors (NET-G2) and four had neuroendocrine carcinoma (NEC) according to the 2010 WHO histopathological classification...

Metformin (MET) has recently emerged as a potentially active agent in cancer prevention and treatment. MET is thought to exert its antitumor effects either via modification of systemic metabolism or through cell-autonomous effects (e.g., activation of AMPK and inhibition of the mTOR pathway). Preliminary findings of the PRIME-NET study suggest that the addition of MET to treatment with everolimus (EVE) and/or somatostatin analogs (SSAs) can provide clinical benefit in diabetic neuroendocrine tumor (NET) patients...

BACKGROUND: In our clinical practice we have observed that despite a high hepatic metastatic tumor burden, serum alkaline phosphatase (AP) levels are frequently normal in cases of metastatic neuroendocrine tumor (NET). PATIENTS AND METHODS: We retrospectively reviewed the records of patients with grade 1 and 2 NETs with liver metastases but without bone metastases seen at our institution in 2013. In total, 49 patients were included (22 female), with a median age of 60 years (range: 28 to 84 years)...

Cytologic diagnosis of extra-adrenal paraganglioma presenting as a peripancreatic mass is challenging with a high error rate due to its rarity. We report two cases of peripancreatic masses identified by radiology. Endoscopic ultrasound-guided fine needle aspiration (FNA) of the masses showed a moderately cellular tumor composed of small to medium sized neoplastic cells with round to oval nuclei, arranged singly and in loose clusters. Focal rosette-like structures were present. The cells were positive for neuroendocrine markers (synaptophysin and chromogranin)...

Background: Large cell neuroendocrine carcinoma of the lung (LCNEC) is a rare disease with poor prognosis and limited treatment options. Neuroendocrine tumors frequently show overactivation of the mTOR pathway. Based on the good activity of the mTOR inhibitor everolimus in different types of neuroendocrine tumors and the results of a previous phase I trial we evaluated the efficacy and safety of everolimus in combination with carboplatin and paclitaxel as upfront treatment for patients with advanced LCNEC...

Metastatic tumor is one of several etiologies of space-occupying masses in the orbit that accounts for 1-13% of all orbital masses. In the adult patient population, breast cancer is the most common tumor to metastasize to the orbit, followed by metastasis from the lung, prostate, and gastrointestinal tract. Carcinoid tumors are rare neuroendocrine neoplasms derived from enterochromaffin cells, which are found primarily in the gastrointestinal tract and bronchial tree. Liver metastases are the classic presentation of distant disease...
