#4162 Functioning neuroendocrine neoplasms: Symptomatic control with 177Lu-DOTATATE

Introduction: Peptide Receptor Radionuclide Therapy (PRRT) with 177Lu-DOTATATE is recommended in unresectable and metastatic gastroenteropancreatic neuroendocrine neoplasms (NENs), however, recommendations for functioning NENs (F-NENs) are not well established. Besides PRRT impact in OS and PFS, real-life benefit in clinical control is also a relevant outcome, especially in F-NENs.

#3921 Mixed neuroendocrine-non-neuroendocrine neoplasms of the rectum: A case report

Introduction: Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms (MiNEN) represent roughly 1-2% of all colorectal malignancies. Given the rareness and heterogeneity of these mixed tumors, recognition and accurate diagnosis remain a challenge. In the absence of established guidelines, they are treated according to the standard of care for pure neuroendocrine carcinomas or adenocarcinomas from similar sites of origin.

#3584 Nodal recurrence after curative surgery for non-functioning pancreatic neuroendocrine tumors: A retrospective cohort study

Introduction: Nodal recurrence occurs in a significant proportion of patients submitted to curative surgery for non-functioning pancreatic neuroendocrine tumors (NF-PanNETs). However, its determinants have been poorly investigated.

#3074 Medullary Thyroid Carcinoma and DIPNECH: An Unexpected Association

Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumour of the C-cells of thyroid gland. Diffuse idiopathic pulmonary neuroendocrine cells hyperplasia (DIPNECH) is a rare condition, thought to be primarily a neuroendocrine proliferative process which can develop into carcinoid tumours.
