#422 The Somatostatin Analogue Octreotide Inhibits Growth of Neuroendocrine Tumor Cells by Triggering Janus Faced Proteins
Introduction: Octreotide is a somatostatin analogue, which improves the management of neuroendocrine tumor (NET) patients. Octreotide acts through somatostatin receptors (SSTRs). However, the molecular mechanisms leading to successful therapy or curative effects are largely unknown, particularly when SSTRs levels are low or absent.

#608 Is Octreotide Benefitial in Patients with Metastatic Gastroenteropancreatic (GEP) and Hepatobiliary Neuroendocrine Carcinoma (NEC)?
Introduction: Neuroendocrine carcinomas (NECs) of the gastroenteropancreatic (GEP) and hepatobiliary (HB) tract are rare and a heterogenous group of malignancies. Octreotide showed the anti-tumor activity in well-differentiated metastatic midgut neuroendocrine tumors (NETs).

#909 Association between Dose of Octreotide and Tumor Control in Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (NETs) represent a heterogeneous group of tumors. Octreotide is used in the symptom control of NETs. The PROMID study demonstrated a benefit of octreotide on disease stabilization in midgut NETs, but a survival analysis was not possible due to insufficient events.

#18 Long-acting release octreotide induce complete response in type 1 gastric carcinoid tumors
Introduction: Gastric endocrine tumors (GET) are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, GET may also be aggressive when sporadic and may sometimes mimic the course of gastric adenocarcinoma. Current incidence of GETs is estimated at around 8% of digestive endocrine tumors. Yearly age-adjusted incidence is around 0.2 per population of 100,000. Gastric carcinoids (ECLomas) develop from gastric enterochromaffin-like cells (ECL cells) in response to chronically elevated gastrin. Type 1 tumors (ECLomas in the course of atrophic gastritis) may occur in conditions of achlorhydria secondary to auto-immune atrophic fundic gastritis. It occurs mostly in women and they are non-functioning tumors, typically found during upper GI endoscopy performed for dyspepsia. ECLomas present frequently as multiple polyps, usually < 1 cm in diameter in the gastric fundus. Type 1 tumors are almost exclusively benign lesions with little risk of deep invasion of the gastric parietal wall. The neoplastic ECL cells become progressively dedifferentiated with an increasing number of Ki-67 immunoreactive (IR) cell nuclei. In addition, there is a substantial decrease in argynophil and IR NE cells that can be visualized by conventional methods. ECLomas secondary to hypergastrinemia should be closely followed for signs of clinical and histopathological tumor progression. Such ECLomas deserve early, active, radical surgical treatment.
Traditionally, gastric carcinoid type 1 (GCA1s) are endoscopically or surgically removed, depending on the number, appearance and size of the tumors. Antrectomy, with surgical excision of the majority of the G cells, is thought to facilitate regression of these tumors by removing the source of excessive gastrin secretion; however, the long-term benefits of antrectomy still remain uncertain. Although proton pump inhibitors are effective in reducing hypergastrinemia-induced gastric acid hypersecretion in GCA2, they do not affect ECL-cell hyperplasia, and therefore their role in GCA1 is limited. Moreover, in selected cases, significant reduction of hypergastrinemia does not prevent development of ECL carcinoid, suggesting that, in addition to hypergastrinemia, other pathogenic or genetic factors may be involved. Treatment with somatostatin analogues (SSA) might impede ECL-cell hyperplasia by suppressing gastrin secretion and/or by a direct anti-proliferative effect on ECL cells. Treatment with SSAs in GCA1 leads to a substantial tumor load reduction, with a concomitant decrease of serum gastrin levels. Published data indicate an important anti-proliferative effect of SSA on ECL cells, providing clinical benefit and obviating, at least temporarily, the need for invasive therapies for GCA1. Morphometric studies demonstrated that, while antrectomy specifically decreased the volume of ECL cells versus the total volume of endocrine cells, octreotide reduces the overall endocrine cell volume. Although the number of treated patients is small, it has been suggested that SSA may exert important anti-proliferative effects either directly, by inhibiting ECL-cells proliferation, or indirectly through suppression of gastrin hypersecretion.

#154 Long-term disease stabilization in a patient with advanced pancreatic neuroendocrine tumor treated with combined everolimus and octreotide LAR after prior failure of cytotoxic therapy
Introduction: Targeting of multiple pathways has become an important strategy for improved tumor control in metastatic neuroendocrine tumors (NETs). Among these targets is the mammalian target of rapamycin (mTOR), a central regulator of cell growth, proliferation, and apoptosis, which is blocked by everolimus, an oral inhibitor of mTOR that has shown efficacy in patients with metastatic pancreatic NETs. Recent evidence has suggested that suppression of insulin-like growth factor-1 receptor (IGF-1R) secretion with octreotide therapy, along with concurrent inhibition of mTOR by everolimus, may improve tumor control synergistically by preventing feedback activation of the PI3K/Akt/mTOR pathway.

#289 Gallium-68 DOTATATE PET CT Frequently Changes Patient Management or Staging When Compared with Indium-111 Octreotide in the Assessment of Neuroendocrine Tumors
Introduction: 68Ga-DOTATATE PET CT offers higher resolution than previous octreotide-labelled scintigraphic techniques, and the literature suggests increased sensitivity for the localization and staging of NETs.
