#4218 Primary hepatic neuroendocrine tumor in a series of 8 cases

Introduction: Primary neuroendocrine (NET) tumors of the liver are extremely rare, accounting for 0.3% of all NETs; unlike metastatic neuroendocrine tumors, rarely cause carcinoid syndrome. Edmonson reported the first case in 1958. Since then, fewer than 150 cases have been reported in the literature. Before making the diagnosis of primary hepatic neuroendocrine tumor it is imperative to explore the patients, several radiological investigations can help to pinpoint the primary which is most often digestive.

#4164 Diagnostic work-up for neuroendocrine tumors of occult primary at diagnosis: A retrospective monocentric study of 60 cases

Introduction: Neuroendocrine tumors (NET) are sometimes diagnosed with an occult primary. Identifying the primary and ruling-out unknown primary NET (NET-UP) has therapeutic implications.

#3995 Pelvic metastases in patients with neuroendocrine tumors: A rare site of metastases

Introduction: Pelvic metastases (PMs) in patients with neuroendocrine tumors (NETs) are rare and develop predominately in women with small intestinal NETs (Si-NETs). The characteristics of NET related PMs and the efficacy of different management options have been poorly investigated.
