#268 Temozolomide as 2.-3. line Treatment of Patients with Poorly Differentiated Neuroendocrine Carcinomas
Introduction: Knowledge of the clinical efficacy of treatment beyond first line of poorly differentiated neuroendocrine carcinomas (PDEC) is sparse. Temozolomide (TMZ) has shown effect in well-differentiated NET.

#311 Treatment and Prognosis of Patients with Poorly Differentiated Neuroendocrine Tumors
Introduction: Poorly differentiated neuroendocrine tumors (PDEC) represent less than 10% of all neuroendocrine tumors but have a poor prognosis.

#602 Antitumoral Effect of Everolimus in Preclinical Models of Poorly Differentiated Neuroendocrine Carcinomas
Introduction: For the small and large cells poorly differentiated neuroendocrine carcinomas (PDNECs) emergency treatment remains the combination cisplatin/etoposide. However, recent studies suggest that targeted therapies could be a therapeutic option for this group of highly aggressive carcinomas.

#100 Mammalian target of rapamycin (mTOR) expression analysis and therapeutic approach in lung and gastroenteropancreatic poorly differentiated endocrine carcinoma (PDEC)
Introduction: PDEC clinically include gastroenteropancreatic PDEC, small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC). These tumors are clinically similar and aggressive and they are usually treated with platinum compounds. mTOR signalling pathway has emerged as a promising target for well-differentiated endocrine carcinoma therapy. Because of varying behavior, PDEC are usually excluded from clinical trials employing the mTOR inhibitor RAD001.

#2248 High Grade (G3) Gastro-Entero-Pancreatic Neuroendocrine Neoplasms: Should the New WHO Classification Apply to All?
Introduction: Grade 3 (G3) neuroendocrine neoplasms (NEN), arising from the gastro-entero-pancreatic system (GEP), are classified according to WHO 2010 and defined as having a Ki67 of > 20%. However this groups together G3 well differentiated neuroendocrine tumours (WD-NET) with poorly differentiated neuroendocrine carcinomas (PD-NEC). Recently, WHO have proposed a new classification for pancreatic NEN, with sub-division into G3 WD-NET and G3 PD-NEC

#620 Multicenter Retrospective Analysis of Systemic Chemotherapy for Advanced Poorly Differentiated Neuroendocrine Carcinoma of Digestive System
Introduction: No standard chemotherapy is established for advanced poorly differentiated neuroendocrine carcinoma (PDNEC) originating from the gastrointestinal tract (GI) or the hepato-biliary-pancreatic system (HBP).

#1199 Tumor Infiltrating Lymphocytes and PD-L1 Expression Differ in Low and High Grade Neuroendocrine Tumors
Introduction: Although much progress has been made in the past 2-3 years in terms of understanding signaling pathways in gastroenteropancreatic neuroendocrine tumors (GEP-NENs), approved treatment options are still limited. Cancer Immunotherapy has been announced as the breakthrough of the year in 2013 and might become an integral part of the clinical management strategy for solid tumors including GEP-NENs. Therefore, to develop immunotherapeutic strategies against NENs we need to know which immune escape mechanisms are relevant in high and low grade NEC/NENs.

#1754 High-Grade Gastroenteropancreatic Neuroendocrine Tumors Compare to Neuroendocrine Carcinomas in 276 Patients
Introduction: The data compared well differentiated high-grade tumors with poorly differentiated neuroendocrine carcinoma (NEC) are very limited.

#2299 Expanding the WHO 2017 Classification to Gastrointestinal Tumors: Real-World Data from the R-GETNE Registry
Introduction: The update of the WHO 2017 classification of pancreatic neuroendocrine tumors (NETs) introduces the distinction between NET & NEC G3, based on histological differentiation. However, little is known about the possibility of extending this concept to non-pancreatic NETs.

#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.
