#1074 Usefulness of a Combination of a 48-Hour Fasting and a Glucagon Tolerance Test
Introduction: The 72-hour fasting test is the gold standard for the diagnosis of insulinoma. However, the test can become a burden for both patients and medical staff and, shortening the duration of fast has been attempted. There are several reports on the high sensitivity of fasting test but only a few reports on its specificity. An insulinoma can be localized using invasive tests such as endoscopic ultrasonography and selective arterial secretagogue injection test. Therefore, insulinoma detection with high specificity may be needed to avoid unnecessary examinations.

#1493 Efficacy and Tolerance of a Simplified Combination of Streptozotocine and Epi-adriamycine in Metastatic Foregut Neuroendocrine Tumor (NET). A Pilot Study
Introduction: Since more than 30 years the combination of Adriamycine (A) and Streptozotocine (STZ) is considered as one of the standard chemotherapy regimens (Moertel et al, N Engl J Med 1992, 326 : 519-23) for patients with aggressive grade 2 metastatic pancreatic NET (PNET).

#1377 Metastatic Neuro Endocrine Tumors: Epidemiological Characteristics, Management and Prognostics Factors. Results from an Inter-Regional Network in France between Upper and Lower Normandy
Introduction: Metastatic neuro-endocrine tumors (MNETs) are rare and their management are complex. To standardize therapeutic strategies in France, a national network of clinicians (RENATEN) has been created, composed of 17 expert centres.

#1787 Towards Personalizing PRRT with [177Lu]-Dotatate to Minimise Renal Toxicity in Neuroendocrine Tumour Patients
Introduction: The kidney is a dose-limiting organ in [177Lu]-Dotatate PRRT (Lutate) and thus renal function is an important prescribing consideration for NET patients. The effect of baseline renal function on kidney absorbed dose is unclear.

#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.
