#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#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.

#161 Low Dose Multiple Cycle (LD/MT) Peptide Receptor Radionuclide Therapy: a new concept for the treatment of well-differentiated metastatic neuroendocrine tumors
Introduction: It has been shown experimentally that low dose radiation can effectively kill slow growing cancer cells. Also, external beam radiation therapy applies a fractionated delivery of radiation dose to reduce toxicity with equal or even better therapeutic efficacy.

#216 Patients Treated for Well-Differentiated Neuroendocrine Tumors: A Study to Evaluate the Ratio of Patients Lost to Follow-up
Introduction: Well-differentiated neuroendocrine tumors (wdNET) are considered more indolent than other epithelial malignancies. Median survival for patients with G1/G2 NET can range from 33 to 223 months.

#219 Predictive Factors of Tumor Control in Patients with Well-differentiated Digestive Endocrine Carcinomas (WDEC) Treated with Lanreotide
Introduction: Somatostatin analogues (SSA) are indicated in the control of secretory symptoms of digestive endocrine tumors. The antiproliferative effect of SSA was recently demonstrated (Rinke et al, JCO 2009).

#501 FOLFOX Regimen for Clinically Aggressive Neuroendocrine Tumors: About one Case
Introduction: The treatment for progressive metastatic well-differentiated pancreatic neuroendocrine tumors is based on adriamycin and streptozotocin chemotherapy, which achieves more than 60% tumor regression. However, severe adverse effects are common.

#534 Effect of Dacarbazine Chemotherapy in Well-Differentiated Neuroendocrine Tumors
Introduction: Despite encouraging results of streptozocin combinations in patients with metastatic endocrine pancreatic tumors, this treatment modality consists of a five-day cycle and can cause renal insufficiency. Dacarbazine (DTIC) (650mg/m2 every four weeks) can easily be applied in an outpatient setting, but data on efficacy are limited.

#901 Impact of Long-Acting Octreotide in Patients with Early-Stage MEN1-Related Duodeno-Pancreatic Neuroendocrine Tumors
Introduction: Somatostatin analogues (SSA) represent one of the main therapeutic options in patients affected by functioning well-differentiated neuroendocrine tumors (NETs). There are no studies specifically focusing on NETs associated with Multiple Endocrine Neoplasia type 1 (MEN1).

#1308 Systemic Treaments and Prognostic Factors in Chinese Patients with Progressive Advanced Well-differentiated Pancreatic Neuroendocrine Tumors
Introduction: Patients with well-differentiated pancreatic neuroendocrine tumors (pNETs) often present with metastatic disease at the time of diagnosis when curative surgery is not feasible. A variety of systemic therapeutic options exist, but the best strategy is still unknown.

#2683 Clinicopathological Features and Prognostic Analysis of 227 Cases with Well-Differentiated Gastric Neuroendocrine Tumors
Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a group of rare tumors with a strong heterogeneity, subdivided as well-differentiated neuroendocrine tumors (NETs, type 1-3 g-NETs) and poorly-differentiated neuroendocrine carcinoma(NECs). WHO classification(2019) for digestive system tumours has carried out a new classification and grading criteria for NENs of the gastrointestinal tract recently, there is very few relevant clinical data based on this new classification, especially for gastric NETs(g-NETs).
