#3852 Novel insights to study the potential of the somatostatin system in NETs and NECs

Introduction: Neuroendocrine tumors (NETs) and carcinomas (NECs) are a heterogeneous group of cancers with increasing incidence worldwide. Surgery is the only curative choice, whereas an effective pharmacological approach for disseminated disease is still lacking. Somatostatin (SS) receptors (SSTs) provide a suitable pharmacological target to treat NETs with SS analogues (SSAs). However, a large proportion of NETs and, particularly most NECs, are unresponsive or resistant to SSAs. The underlying causes remain poorly understood and alternative strategies are needed. Recently, cortistatin (CST), a neuropeptide analogue of SS with comparable affinity to SSTs, emerged as an anti-inflammatory player, with potential antitumoral features.

#1688 Pancreatic NET-G3 Does Not Respond to Platinum-Based Chemotherapy: A Multicenter Study of Neuroendocrine Carcinomas

Introduction: Recent studies　have shown that Pancreatic neuroendocrine carcinomas (NECs) contain well-differentiated NETs with high proliferative activity (WDNET-G3), as well as poorly differentiated NECs (PDNECs). Although patients with pNEC show variable responses to platinum-based chemotherapy, predictors of the response are unknown.
