#4654 Usefulness of soluble tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptors R2 and R3 in progression assessment of gastroenteropancreatic neuroendocrine neoplasms – A preliminary study

Introduction: TRAIL is a member of TNF family and appears in membrane and soluble (s) forms. It acts either triggering (R1 and R2) or blocking (R3 and R4) apoptosis. TRAIL targeted therapy is widely studied and known as potentially effective in number of neoplasms.

#4574 Long-acting somatostatin analogue injections for treating gastroenteropancreatic neuroendocrine tumours (GEP-NETs) and acromegaly: BackSOM – A patient preference study

Introduction: Long-acting somatostatin analogues, lanreotide and octreotide, are indicated for first-line treatment of GEP-NETs and acromegaly. Lanreotide was approved in 2007 in Europe, and is supplied as a prefilled, ready-to-use syringe (LAN-PF). In 2021, a generic form of lanreotide was released and supplied in a syringe requiring assembly (LAN-RA). To ensure patient compliance with treatment, it is important to understand their injection experiences.

#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.

#4497 Complex management of a long-term gastrinoma survivor with multimodal treatment approaches

Introduction: The prognosis of pancreatic gastrinomas is influenced by tumour burden, extent of metastasis, and treatment response, with 5-year survival rates ranging from 20% to 40%. Treatment for well-differentiated tumours typically include locoregional therapies, long-acting somatostatin analogues, molecular targeted agents, radionuclides, and chemotherapy.

#4090 Octreotide infusion pump in patients with functional neuroendocrine tumors and refractory hormonal syndromes

Introduction: In patients with metastatic functional neuroendocrine tumors (NETs), symptoms are, sometimes, not adequately controlled with long-acting somatostatin analogues (LASSAs), so patients need to use boost subcutaneous (sc) octreotide injections (inj) daily. However, this approach is not always effective and convenient for the patients.
