#2911 Pancreatic Neuroendocrine Neoplasms and GastroIntestinal Stromal Tumours: A Single-Institution Experience of a Rare Association and Review of the Literature
Introduction: Pancreatic neuroendocrine neoplasms (pNENs) and gastrointestinal stromal tumours (GISTs) are both rare neoplasms, and they have an estimated incidence of about 1/100,000 per year and about 1-1.5/100,000 per year, respectively.

#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression
Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#2733 Pancreatic Metastases Originating from Intestinal Neuroendocrine Tumours
Introduction: Pancreatic metastases are rare, accounting for 1 to 2% of pancreatic tumours. Data on pancreatic metastases of intestinal NETs are lacking.

#2736 Second Primary Neoplasms in Patients with Neuroendocrine Neoplasms (NEN): DATA from a Retrospective Multicentric Study
Introduction: Patients with sporadic gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NEN) may exhibit a higher risk of second primary tumors than the general population.

#2903 Bone Metastases (BM) in Neuroendocrine Tumors (NET): Imaging Characteristics and Clinical Implications. A Single-Institution Experience
Introduction: The incidence of BM in NET is underestimated and there is no consensus on clinical features, diagnostic techniques, and treatment options.

#2920 Mutation Spectrums Analysis of Colorectal Adenocarcinoma and Neuroendocrine Neoplasm Based on Same Genetic Background to Reveal Tumorigenesis
Introduction: The tumorigenesis of neuroendocrine neoplasm (NEN) are still ambiguous. The therapies of NENs in colon or rectum refer to adenocarcinomas (AC) when tumor metastasis, but the response was unsatisfactory which inspired us to explore the mutation difference.

#3081 An Atypical Presentation of a Neuroendocrine Carcinoma of Unknown Origin
Introduction: Neuroendocrine carcinomas (NEC) of unknown primary site are uncommon. Most arise from an occult/clinically undetectable primary. Primary NEC of genitourinary tract are rare. High-grade (HG) carcinoms, are rapidly growing and aggressive but usually responsive to platinum-based combination chemotherapy.

#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.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.

#141 Incidence of second primary tumors in patients with neuroendocrine tumors
Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.
