#4215 Breast neuroendocrine carcinomas surgery: A case report

Introduction: Breast carcinoma with neuroendocrine differentiation, also known as breast carcinoma (NEBC), (1) includes a heterogeneous group of rare tumors, which account for 2–5% of (2.3) all invasive breast carcinomas, less than 1% of neuroendocrine tumors. Large cell carcinoma of the breast represente < 0.1% of primary breast cancers; rarer than small cell carcinoma. Occur mainly in the 6th decade (2).

#4008 Mapping of lymph node metastasis in non-functional pancreatic neuroendocrine tumors: A retrospective analysis of 455 patients

Introduction: Radical surgery is the best and effective option for resectable pancreatic neuroendocrine tumor (pNET) patients. However, lymphadenectomy in pNET surgery remains controversial, especially for small tumors.

#3784 High uptake of 18F-FDG in the primary tumor of pancreatic neuroendocrine tumor is an independent predictor for lymph nodes metastasis

Introduction: Operation is primary treatment of pancreatic neuroendocrine tumor (pNET). However, the indications for resection and lymph node dissection are still controversial.

#3570 Metastatic middle ear neuroendocrine tumor treated with Somatostatin analogues and PRRT – A case report

Introduction: Neuroendocrine adenomas of the middle ear (NEAME) are rare tumors. They have mostly indolent biological behaviour, however, reports of an aggressive course and metastasis have been described.
