#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.

#53 The rise and fall of chromogranin A as an indicator for NET
Introduction: There is now general awareness that treatment with proton pump inhibitors (ppi) may cause moderate rises in circulating concentrations of gastrin and/or chromogranin A (CgA), thus decreasing the specificity of these markers in the diagnosis of neuroendocrine tumors (NETs). Due to their high efficacy, proton pump inhibitors (ppi) are one of the most frequently prescribed classes of drugs worldwide. Several studies in various countries report that 30% or more of in-patients have been prescribed ppi. Patients who are suspected of having a neuroendocrine tumor (NET) often have gastrointestinal (GI) symptoms for which ppi are prescribed and therefore they may be already taking ppi when their first blood sample is assayed for NET markers. We previously encountered a case of extreme rise in CgA which flagged the possibility of a NET, but was later shown to be due to ppi therapy alone. We present CgA and gastrin data in relation to ppi therapy and withdrawal for this patient. In order to see if this was an isolated incident, we audited all laboratory requests for CgA/gastrin in a two-year period and monitored those that provided details of ppi treatment/withdrawal.

#1918 Case Study: Immunotherapy in a Young Adult with Atypical Neuroendocrine Tumour
Introduction: Use of immunotherapy PD-1 antibody has emerged as a novel therapeutic option for treating multiple solid tumors. In the setting of neuroendocrine tumors (NETs), little is known. Currently, trials are underway investigating its use in high-grade NETs, but outcomes remain to be seen

#37 Gastric GIST with synchronous neuroendocrine tumor of the pancreas, Case Report and Literature Review
Introduction: The Gastrointestinal Stromal Tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. These are rare tumors with an incidence of 15 new cases per million per year. They often occur in individuals over the age of 40 years, without gender predominance. The clinical behavior is variable and benign tumors are the most common. They can develop anywhere in the GI tract, but are more frequent in the stomach and small intestine. The primary treatment, when located, is the surgical resection, which can be complemented with the use of imatinib.
The occurrence of neuroendocrine tumors of the pancreas is rare, representing 1-5% of pancreatic cancers, and it is estimated that its incidence does not exceed 5 to one million. The tumors considered nonfunctioning (15-32% of pancreatic neuroendocrine tumors) are not associated with any syndrome, and are usually incidental. They have a slight predominance in males, and are more frequent in the 6th decade of life. Nonfunctioning tumors of islet cells are virtually all malignant tumors, and the treatment consists of surgical resection.
