#3887 Characteristics and management of high grade gastroenteropancreatic neuroendocrine neoplasms – A Belgian retrospective analysis from the DNET & NETwerk registry

Introduction: High grade gastroenteropancreatic neuroendocrine neoplasms (HG-GEPNEN) comprise neuroendocrine carcinoma (NEC) and well-differentiated neuroendocrine tumors (NETG3). These entities exhibit many differences in behaviour, prognosis and sensitivity to chemotherapy. Data about their optimal management are still scarce.

#3720 Efficacy of somatostatin analogues (SSA) in G3 neuroendocrine neoplasms – A comprehensive analysis among the SwissNET cohort

Introduction: G3 differentiated neuroendocrine neoplasms (NEN) are divided into G3 NET and NEC depending on their histological appearance and proliferation index. The literature on different systemic treatment options in these G3 entities is scarce especially for use of somatostatin analogues (SSA).

#3501 The dominant role of pancreatic and pulmonary NET G3 in a large consultation center series

Introduction: NETs G3 have been reported mostly in the pancreas, but other primary sites have not been well-investigated. Pulmonary atypical carcinoids corresponding to NET G3 were observed as metastases. Little is known about the progression of primary NETs to metastatic NET G3.

#3406 Neoadjuvant treatment in locally advanced pancreatic neuroendocrine tumor G3

Introduction: Bordeline or locally advanced pancreatic neuroendocrine tumors are potentially resectable in selected cases. The role of neoadjuvant chemotherapy has not been established, and there are published only few small studies dealing with this issue.

#3259 Treatment outcomes of patients with G3 neuroendocrine neoplasms

Introduction: Extrapulmonary neuroendocrine carcinomas (NEC) and neuroendocrine tumors (NET) G3 are aggressive neoplasia that are associated with a limited prognosis.
