#2143 Efficacy and Safety of Anti-PD-1 Antibody (IBI308) in Treating Advanced Neuroendocrine Neoplams
Introduction: Neuroendocrine neoplasms (NENs) are a series of disease which show highly heterogeneity but have limited treatment options. Previous studies showed that tumor mutation burden (TMB) in NEC was relatively high which is considered as a predictive marker of anti-PD-1 antibody.

#2259 Clinical Characteristics, Treatment Outcomes and Potential Novel Therapeutic Options for Patients with Prostatic Neuroendocrine Carcinoma
Introduction: Prostatic neuroendocrine carcinomas (PNECs) are rare tumors with poor prognosis. While platinum and etoposide based chemotherapy regimens (PE) are commonly applied in first-line for advanced disease, clinical-grade evidence for treatment options in second-line and beyond is very limited.

#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

#2199 Systematic Evaluation of the Immune Microenvironment of Neuroendocrine Tumors (NET)
Introduction: Immunotherapy is being explored in many tumour types with encouraging results, but
its role in the management of NET is yet to be defined.

#1925 SSA-, H1, H2- and Leukotriene Receptor Blockade Eliminates Handicapping Symptoms from Atypical Carcinoid Syndrome
Introduction: The patient is a female, 59 yrs , previously healthy except from mild allergic rinitis since 12 years of age and at 49 a suspected anaphylaxis after hazelnut intake.

#387 Combined Blockade of Several Signalling Pathways Shows Marked Anti-Tumor Potential in Two Novel Mouse Phaeochromocytoma Cell Lines
Introduction: The current study explores novel targeted therapies for malignant pheochromocytomas (PCCs) and paragangliomas, utilizing a more benign (MPC) and a more malignant (MTT) PCC cell line. We have previously shown that the dual PI3K/mTORC1 inhibitor NVP-BEZ235 significantly reduced MPC and MTT cell viability, but increased ERK signalling.

#1864 Analysis of mTOR, CXCR4 and PD-1 Checkpoint Pathways in Merkel Cell Neuroendocrine Carcinomas: Correlations with Prognosis and Viral Status
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine tumor. Prognostic factors currently included in the reference AJCC classification are mainly clinical.

#1780 PD-L1 Is Expressed in a Subset of Pancreatic Neuroendocrine Tumors (pNET)
Introduction: Programmed death 1 (PD-1) is an immune inhibitory receptor expressed on several immune cells, interacting with two ligands, PD-L1 and PD-L2. The former is expressed in many human cancers and is used as a selection criterion for indication of checkpoint inhibitor therapies. PD-L1 is also a potential target for checkpoint inhibitors in pNET therapy, however no data on prevalence of PD-L1 expression and potential associations to clinico-pathologic features is available.

#1797 An Open-Label Phase II Study to Evaluate the Efficacy and Safety Of PDR001 in Patients with Advanced Well-Differentiated Non-Functional NET of Pancreatic, Gastrointestinal (GI), or Thoracic Origin Who Have Progressed on Prior Treatment
Introduction: Monoclonal antibody (mAb) inhibitors of immune checkpoints, including anti-PD-1 and anti-PD-L1, have become established treatment (tx) options in various solid tumors. However, there is a paucity of data on checkpoint inhibitors in NET. In a phase I trial of PDR001 (mAb checkpoint inhibitor targeting PD-1) conducted in patients (pts) with multiple solid tumor types, a pt with histologically confirmed metastatic atypical pulmonary carcinoid demonstrated a RECIST-based tumor response and clinical benefit.

#2071 ElevatION:NET-201 A Phase II Study to Evaluate the Efficacy and Safety of PDR001 in Patients with Metastatic, Well-Differentiated NET of Pancreatic/GI/Thoracic Origin or Poorly-Differentiated GEP NEC Who Have Progressed on Prior Treatment
Introduction: Monoclonal antibody (mAb) inhibitors of immune checkpoints, including anti–PD-1 and anti–PD-L1, have become established treatment options in various solid tumors. However, there is a paucity of data on treatment effect of checkpoint inhibition in neuroendocrine tumors (NET) and neuroendocrine carcinoma (NEC). PDR001 is a high-affinity, humanized IgG4 mAb directed against PD-1 that blocks the binding of PD-L1 and PD-L2 to PD-1.
