#3052 Unique Metastatic Patterns in Neuroendocrine Neoplasms of Different Primary Origin

Introduction: Neuroendocrine neoplasms (NEN) can originate in different organs, e.g. in the gastro-enteric tract (GE), pancreas (P) or lung (L). Despite similarities in clinical and pathological characteristics in tumors of another origin, differences also exist. This might apply to metastatic patterns as well, but only limited data is available so far.

#3036 Can Ki-67 with 5.5% Be Better in Predicting Prognosis for Well Differentiated Pancreatic Neuroendocrine Tumors?

Introduction: Pancreatic neuroendocrine tumors (NETs) are rare malignancies, Ki-67 is a cell proliferation marker that has been shown to have some utility in predicting prognosis of neuroendocrine tumors. However, the ideal grading method for G1/G2 remains controversial.

#3014 The Number of Positive Nodes Accurately Predicts Recurrence after Distal Pancreatectomy for Nonfunctioning Neuroendocrine Neoplasms

Introduction: The most appropriate staging system of metastatic lymph nodes (N) for resected pancreatic neuroendocrine tumors (PanNETs) remains unclear, especially regarding those resected by distal pancreatectomy (DP).

#2971 A Retrospective Multicentre Evaluation of the Outcomes and Management of Carcinoid Heart Disease in Patients with Advanced Midgut NETs: A NET-CONNECT Descriptive Study

Introduction: Carcinoid heart disease (CHD) is a poor prognostic factor in neuroendocrine tumours (NETs). However, the extreme variability of diagnostic and treatment approaches reported in literature account for uncertainties on the best management in this selected population.

#2963 Intrinsic Gene Programs in Metastasis-like Primary Subtype Is Associated with Early Metastatic Evolution in Pancreatic Neuroendocrine Tumours

Introduction: Three molecular subtypes of pancreatic neuroendocrine tumours (PanNETs) have been described: insulinoma-like, intermediate and metastasis-like primary (MLP). The Latter is a non-functional tumours with highly metastatic potential. A mouse model of PanNET showed that MLP subtype has two different pathways of progression including stem/progenitor and epithelial-to-mesenchymal transition. However, the evolution of metastasis in patients requires further studies.
