#2881 Patient-Derived Tumor Xenograft Combined with Chemotherapy Drug Sensitivity Test in a Patient with Pancreatic Neuroendocrine Carcinoma

Introduction: Pancreatic neuroendocrine carcinoma (p-NEC) with liver metastasis has a poor prognosis. The treatment is mainly chemotherapy which is now still a huge challenge on NEC with high ki-67 index.

#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.

#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.

#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.
