#2695 Different Treatment Options for Patients with Advanced Gastrointestinal Neuroendocrine Tumors
Introduction: Low sensitivity to chemotherapy leaves open question of optimal approach to drug therapy of neuroendocrine tumors (NETs). Somatostatin analogues (SSA) (octreotide, lanreotide) and mTOR inhibitors are successfully used in treatment.

#2945 Misdiagnosis of Pancreatic Neuroendocrine Carcinoma - A Potential Threat
Introduction: Pancreatic neuroendocrine tumors (PNETs) are a rare clinical entity.Very less data is available in Pakistan on PNETs.Common metastatic sites are liver, lung and brain Reports involving metastasis to breast are almost negligible.

#2972 Characteristics and Management of Paragangliomas, 10 Years Experience
Introduction: Paraganglioma (PG) is a rare extra-adrenal neuroendocrine tumor, with common sites of presentation being abdomen, and head and neck region. The majority of PGs appear to be sporadic. However, almost half of cases are associated with an inherited syndrome. The highest malignancy rates are seen in paragangliomas (PGs) associated with SDHB mutations, which are usually abdominal and secretory.

#2983 Differential TGF-β Signalling in Typical and Atypical Bronchial Carcinoids
Introduction: Typical and atypical bronchial carcinoids (TBC and ABC) are well-differentiated neuroendocrine neoplasms (NEN). Metastatic BC having low to moderate mitotic count may still be treated with somatostatin analogues and mTOR inhibitors; however, TBC and ABC have been reported to respond very differently to therapy and an effective treatment algorithm is still lacking. TGF-β is known for its ability to activate mTOR pathway and induce epithelial mesenchymal transition, affecting cell pathophysiological capabilities such as proliferation, migration and tissue invasiveness.

#3021 Homecare Service for Administration of Lanreotide Autogel Injections: Assessment of Patients’ Experience
Introduction: In the past, all Neuroendocrine Neoplasm (NEN) patients (pts) on long-acting somatostatin analogues (SA), had to attend local hospitals/clinics to have them administered by nurses/doctors. Recently, a “homecare service” was developed, allowing pts to have their injections delivered to their home and injections were either administered by themselves, their partner or a Specialist Nurse (SN).

#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.

#3057 Epidemiological Features of Patients with NeuroEndocrine Neoplasms (NENs): Preliminary Results of an Observational Study by the Hellenic Society of Medical Oncology (HeSMO)
Introduction: NENs are rare tumors and can grow in almost all tissues. Regardless histological, molecular and imaging characteristics that are indicative of the primary origin, a significant percentage remain of unknown primary.

#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.

#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment
Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.
