#2866 Extrahepatic 68Ga-DOTATATE-Avid Tumor Volume and Serum Chromogranin A Predict Short-Term Outcome of 177Lu-DOTATATE in Late-Stage Metastatic Gastroenteropancreatic Neuroendocrine Tumors
Introduction: 177Lu-DOTATATE is an effective therapy for somatostatin receptor-positive neuroendocrine tumors (NETs). Often enough 177Lu-DOTATATE is used as the last treatment resort in advanced NET.

#2890 Evaluation of Toxicity in Peptide Receptor Radionuclide Therapy (PRRT) for Neuroendocrine Tumors (NET)
Introduction: Peptide receptor radionuclide therapy (PRRT) is an encouraging systemic treatment for neuroendocrine tumors (NET). PRRT is generally safe and possesses little side effects but little is known about liver toxicity.

#2897 Comparison of 68Ga-DOTATATE PET/CT for Assessment of Response to Peptide Receptor Radionuclide Therapy after 2 and 4 Cycles of 177Lu-DOTATATE: Preliminary Single Academic Center Experience
Introduction: Peptide receptor radionuclide therapy (PRRT) usually leads to stable rather than decreased lesion size in neuroendocrine tumors (NETs), therefore RECIST criteria are not used to assess early response to treatment.

#2956 Somatostatin Analogs: The Economic Value of Lanreotide Autogel Delivery Attributes in the Treatment of GEP-NET versus Octreotide LAR – A UK Budget Impact Analysis
Introduction: Lanreotide autogel (LAN) and octreotide long acting release (OCT) are long-acting somatostatin analogues (LA-SSAs) used to treat patients (pts) with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). However, the treatments differ in terms of injection route, need for administration by a health care professional and dosing interval.

#2969 Lanreotide Autogel and Octreotide LAR Treatment Patterns: Results from a Nationwide French Retrospective Study
Introduction: Lanreotide autogel (LAN) and octreotide LAR (OCT) are long acting somatostatin analogues (LA-SSAs) used to treat acromegaly and gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Previous studies conducted in North America and Sweden showed some differences between both LA-SSAs in terms of dose and persistence.

#2730 FOLFIRINEC, A Multi-Center, Randomized, Comparative Phase II Study of FOLFIRINOX vs Platinum-Etoposide as First Line Treatment for Metastatic Neuroendocrine Carcinoma of Gastroenteropancreatic or Unknown Origin, Associated with Molecular Profiling
Introduction: Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine carcinoma (NEC) are rare diseases with a poor prognosis. FOLFIRINEC is a multicenter comparative phase II study of mFOLFIRINOX vs platinum-etoposide (PE) as first line treatment for metastatic G3 NEC of GEP or unknown origin.

#2824 Patient and Nurse Satisfaction with the New Lanreotide Autogel Pre-Filled Syringe in Neuroendocrine Tumors (NET): A Prospective Study (SONATE)
Introduction: A new syringe (NS) for the delivery of lanreotide autogel was approved in Oct 2018 in France. The NS includes updated features (larger flanges, more robust plunger) intended to ease the injection.

#3041 Resource Use in Patients with Carcinoid Syndrome: A Retrospective Analysis Using the French Health Insurance National (SNDS) Database
Introduction: About 20% of patients (pts) with neuroendocrine tumors (NET) suffer from carcinoid syndrome (CS), mainly from ileum and lung NET. Pts with CS experience symptoms such as diarrhea, flushes and cardiac complications. The diarrhea occurs in almost all pts with CS and can be truly debilitating. Therefore, on top of the tumor, the burden of the symptoms further impairs quality of life and is associated with additional costs related to symptom management and pts follow-up.

#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.
