#1777 Tumour Size Is Not a Reliable Criterion for Resection of Patients with Non-Secreting Pancreatic Neuroendocrine Tumours: Results of an International, Multi-Centre, Operative Cohort
Introduction: Small pancreatic neuroendocrine tumours (pNETs) present a management dilemma between surveillance and resection.

#2077 Linked Colour Imaging Increases the Diagnostic Yield of Type 1 Gastric Carcinoids
Introduction: Type 1 Gastric carcinoid tumours (GCTs) are the most common neuroendocrine tumours of the stomach. Endoscopic diagnosis of Type 1 GCTs remains a challenge. White light endoscopy (WLE) and Narrow Band Imaging (NBI) have failed to demonstrate reliable endoscopic signs of carcinoid.

#1890 Natural History of Type 1 Gastric Carcinoid (gNENs) and Risk of Adenoma/Adenocarcinoma in Endoscopic Surveillance Programme
Introduction: Patients with gNENs & autoimmune gastritis are exposed to 2 malignant risks: 1)transformation of gNENs, felt to be low & guidelines advocate either resection of all lesions or selective endoscopic mucosal resection(EMR) of larger lesions; 2)ill-defined risk of gastric adenoma/adenocarcinoma.

#375 How Long to Continue Surveillance in Patients Following ‘Curative Resection’ of Primary Small Bowel Tumors?
Introduction: Around 40-50% of patients with small bowel (SB) NETs have metastatic disease at the time of presentation. The majority of the remainder proceed to surgery for attempted curative resection. The optimal duration of surveillance post ‘curative surgical’ resection of primary SB NETs is unknown.

#29 Serum chromogranin A correlation with tumor burden in metastatic small bowel carcinoid patients
Introduction: Patients with neuroendocrine tumors may have clinical courses that range from fairly indolent to more aggressive. Cross–sectional studies, nuclear imaging and biochemical markers are often used to monitor disease progression. Optimal surveillance tests and intervals have not been firmly established. Studies suggest that chromogranin A (CgA) may be a surrogate marker for tumor burden.

#306 The Risk of Metachronous Cancers In Patients with Small Intestinal Carcinoid Tumors
Introduction: Small intestinal carcinoids (SIC) are the most common small bowel malignancies. No population-based study has examined the risk for, and prognosis of, metachronous cancers and SICs.

#927 Laparoscopic Antrectomy: A Safe and Definitive Treatment in Managing Type 1 Gastric Carcinoids
Introduction: Various type 1 gastric carcinoid (T1GC) treatments exist, including esophagastroduodenoscopy (EGD) observation, polypectomy, and antrectomy, but studies comparing treatment outcomes have been limited.

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.
