#4665 Prognostic value of systemic inflammatory parameters in neuroendocrine tumour patients treated with peptide receptor radionuclide therapy – Preliminary results

Introduction: PRRT (177Lu-Dotatate) is a therapeutic option for advanced NETs (neuroendocrine tumours). Systemic inflammatory parameters, such as NLR, PLR, SII, and other ratios derived from complete blood counts, are considered prognostic markers in NETs and other malignancies.

#4556 Optimising the establishment of patient-derived models for neuroendocrine neoplasms

Introduction: Neuroendocrine neoplasms (NENs) are clinically and molecularly diverse, with limited understanding of their tumour biology. Efforts to develop patient-derived models have been unsuccessful, highlighting an urgent need for accurate models to support fundamental research.

#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.

#4528 Serum visfatin concentration in metastatic pancreatic and midgut NETs: An exploratory study

Introduction: Neuroendocrine tumours (NETs) are commonly diagnosed at advanced stages due to their diverse and often asymptomatic clinical presentation. Visfatin, an adipocytokine involved in regulating cellular energy homeostasis, inflammation, and tumorigenesis, has been investigated as a potential biomarker in several neoplasms. However, its role in NETs remains unexplored.
