#4660 Clinical significance of interval imaging in patients with well-differentiated neuroendocrine neoplasms (NENs) receiving peptide receptor radionuclide therapy (PRRT)

Introduction: PRRT is an effective therapy for advanced NENs with SSTR-avid disease, however, the role of interval imaging in between PRRT cycles and its benefit is unknown.

#4549 Alpha-Fetoprotein as a valuable biomarker in neuroendocrine tumours

Introduction: Neuroendocrine tumours (NETs) are a rare group of tumours that pose a significant diagnostic, therapeutic, and prognostic challenge. This complexity arises from the diversity and heterogeneity of these neoplasms, as well as from the limitations of commonly used biomarkers in clinical practice. Alpha-fetoprotein (AFP) is a fetal protein widely used primarily for congenital defects in prenatal diagnostics and in certain malignancies in adults.

#4492 Utility of NETest 2.0 as a biomarker for neuroendocrine tumours: The Swiss experience – Real-world data

Introduction: The NETest 2.0 is a PCR assay of circulating mRNA, scored 0-100. It has been developed as a biomarker to diagnose neuroendocrine neoplasia (NEN) and to provide tumour prognostic information.

#4420 Nab-paclitaxel plus bevacizumab for patients with previously treated, metastatic extrapulmonary neuroendocrine carcinomas (EP-NECs): A multicentre, open-label, phase II trial

Introduction: No standard therapies beyond first line are established for advanced EP-NECs. Paclitaxel is also active in NECs however there is no data on the role of nab-paclitaxel.
