#2875 Immunotherapy as Second-line Treatment in Grade 3 Neuroendocrine Carcinomas: A Prospective Case Series from an ENETS Center of Excellence
Introduction: Metastatic WHO grade 3 extra-pulmonary neuroendocrine carcinomas (EP-NEC) have a poor prognosis and optimal treatment after first-line platinum-etoposide chemotherapy remains unclear. A recent, small phase II study combining ipilimumab and nivolumab showed promising results

#2964 Personalized Therapy in a Case of Esophageal NEC Based on Tumor Genome Sequencing
Introduction: High-grade esophageal neuroendocrine carcinomas (NEC) constitute a rare subgroup of neuroendocrine neoplasms, with a particularly aggressive behaviour and unfavourable prognosis. To date, there are no validated biomarkers for personalized therapy and cytotoxic chemotherapy remains the standard of care. However, tumor genome sequencing may help improve NEC molecular landscape knowledge in order to identify novel targets for an individualized approach.

#2940 Avelumab in Unresectable/Metastatic, Progressive, Poorly Differentiated, Grade 3 Neuroendocrine Carcinomas (NECs)
Introduction: Poorly differentiated, G3 NECs are associated with poor outcomes and have no effective treatment options apart from cytotoxic chemotherapy.

#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.

#1448 Distribution of T-Cell Infiltrate in G1, G2 and G3 NENs
Introduction: The identification of T-cell infiltrate and the expression of inhibitory molecules in the tumor microenvironment could lend support to the use of immunotherapy in the treatment of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs).

#1561 PD1 and PDL1 Expression in Midgut Neuroendocrine Tumors
Introduction: PD1/PDL1 inhibitors have shown promising results in different carcinomas, and correlation between PDL1 expression and response to immunotherapy has been reported. No studies thus far have investigated the expression of PD1 or PDL1 in midgut NETs.

#1726 A Long-Term Complete Response (CR) of Avelumab in Patient (pt) with Advanced Merkel Cell Carcinoma (MCC)
Introduction: MCC is a rare and aggressive cutaneous neuroendocrine cancer linked to exposure to the Merkel Polyomavirus (MCPyV). Cisplatin and VP16 chemo may be an effective treatment for metastatic MCC, but responses are often transient. The blockade of programmed death 1 (PD-1) immune inhibitory pathway by avelumab, an anti-PD-L1 checkpoint inhibitor, is being investigated in solid neoplasms. This strategy can also be of interest in MCC because these tumors often express PD-L1
