#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.

#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.

#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.

#2047 IMMUNeOCT Study: The Role of Octreotide LAR in Modulating the Immune Response in Patient with Neuroendocrine Tumors. EudraCT Number 2017-001613-83
Introduction: SSAs are used in the treatment of G1/G2 Neuroendocrine Neoplasms (NEN) in order to control symptoms and induce tumor shrinkage with an excellent tolerability profile. The role of immune response is crucial in defining the clinical response to treatment through the active stimulation of effector cells (T and NK cells) but also through the inhibition of tumor-induced immune suppression. The immune regulatory cells CD4-CD25-expressing Tregs and myeloid cellsMDSC can contribute to disease progression through various mechanisms.

#2068 Durvalumab plus Tremelimumab for the Treatment of Patients (pts) with Advanced Neuroendocrine Neoplasms (NENs) of Lung or Gastroenteropancreatic (GEP) Origin. A Phase II Multicohort Trial (DUNE Trial / GETNE 1601)
Introduction: Immuno check-point inhibitors development in grade 1-2 NENs is limited by low mutation tumor load and PD-1/PDL-1 expression. The combination of an PDL-1 and CTLA-4 inhibitors could increase the probability of success in this setting. In high grade NENs the rational for immunotherapy is stronger based on experiences in small cell lung cancer.

#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.

#1918 Case Study: Immunotherapy in a Young Adult with Atypical Neuroendocrine Tumour
Introduction: Use of immunotherapy PD-1 antibody has emerged as a novel therapeutic option for treating multiple solid tumors. In the setting of neuroendocrine tumors (NETs), little is known. Currently, trials are underway investigating its use in high-grade NETs, but outcomes remain to be seen

#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.

#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).
