#4637 Non-functional retroperitoneal paraganglioma in a young patient: A case report

Introduction: Paragangliomas are neuroendocrine tumours arising in the parasympathetic nervous system, outside the adrenal gland. Retroperitoneal location is extremely rare. Non-functional paragangliomas often represent a diagnostic challenge.

#4628 Triple negative breast neuroendocrine carcinoma in older patient: A rare entity

Introduction: Neuroendocrine breast carcinoma is a rare histological form of breast cancer, that represent 0.1% of all breast cancers and is recognised by the World Health Organization as a distinct entity. Characterised by a non-specific clinical and radiological presentation. Therapeutic management is not codified and is usually superimposed on that of classical breast cancer.

#4500 Effectiveness of palbociclib plus letrozole as first line therapy of metastatic breast neuroendocrine carcinoma: A case report

Introduction: Palbociclib plus endocrine therapy is the standard treatment of advanced luminal breast cancer. However, we lack data on its effectiveness in breast neuroendocrine carcinoma (NEC).

#3771 Epidemiological profile and survival of neuroendocrine tumors of the ampulla of Vater

Introduction: Duodenal neuroendocrine tumors are rare, they represent nearly 2% of digestive NETs. Their incidence is increasing due to better detection. The diagnosis is often late because of the non-specific symptomatology of the tumor. The 5-year survival of duodenal NETs is 68% when the tumor is diagnosed at an early stage.

#3634 Imaging surveillance in multiple endocrine neoplasia type 1 – 10 years of experience with somatostatin receptor positron emission tomography

Introduction: Guidelines for multiple endocrine neoplasia type 1 (MEN1) recommend intensive imaging surveillance without specifying a superior regimen, including the role of somatostatin receptor imaging (SRI) with positron emission tomography (PET).
