#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.

#3779 177Lu-DOTATATE in advanced neuroendocrine neoplasms of different locations – Data from 552 cases in the SEPTRALU registry

Introduction: Peptide receptor radionuclide therapy (PRRT) is a therapeutic strategy selected via a marker, somatostatin receptor (SSTRs) expression, with activity in gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). Its role in tumor sites outside the digestive tract remains unclear.

#3772 R-ache-L score – A nomogram model for predicting prognosis of lung neuroendocrine tumors according to primary tumor side

Introduction: The prognosis of atypical carcinoids (AC) is worse than that of typical carcinoids (TC). Molecular analyses have suggested a more heterogeneous disease for the first ones. However, no previous study has established an individualized predictive model for the prognosis of lung neuroendocrine tumos (Lu-NETs) considering the location of the primary tumor in the right versus left lung parenchyma.

#3241 Clinical features and management of paragangliomas in a tertiary university hospital

Introduction: Paragangliomas (PG) are rare neuroendocrine tumors that arise from the extra-adrenal paraganglia. The most frequent location is head and neck PG (HNPG), usually non-functioning tumors. PG present a high rate of genetic susceptibility mainly associated with SDHx mutation. Clinical presentation depends upon catecholamine secretion and tumor location. Surgery remains the standard treatment, although radiotherapy and systemic therapies can be considered for unresectable or metastatic disease.

#2957 New Evidence of Emerging Nodal Metastasis in Staging System after Surgical pNET Resection as Predictive Factor for Recurrence. Result from Monocentric Retrospective Series

Introduction: New evidence is emerging of the role of pNETs lymphatic metastasis in terms of Oncological Outcomes. A specific staging classification is not actually available.
