#4646 Dysregulated miRNA in patients with GEP-NEN and potential role as circulating biomarker

Introduction: Neuroendocrine neoplasms (NENs) are a class of rare and molecularly extremely heterogeneous tumours. NENs arise predominantly in the gastrointestinal (GEP) and pulmonary tracts but can also involve thyroid and breast. NENs often present with non-specific symptoms and lack early specific biomarkers, leading to frequent metastatic diagnoses and primary site challenges.

#4620 Impact of the extent of surgical resection on the development of post-operative diabetes in patients undergoing distal pancreatectomy for non-functioning pancreatic neuroendocrine tumours (NF-PanNET)

Introduction: Pancreatic neuroendocrine tumours (PanNETs) are often indolent neoplasms. Surgery is the primary curative approach for localised non-functioning (NF) PanNETs, but it poses a risk of long-term complications, such as diabetes, impacting quality of life.

#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.

#4378 Hypoxic signalling in pancreatic NETs (pNETs)

Introduction: In a genomic profiling study conducted as part of the COMPOSE Phase III multicentre open-labelled clinical trial we assessed 9 pNET patients, 2 of which showed upregulation of CA9 and hypoxic signalling. Hypoxic tumour cells present CA9 for extracellular proton channelling, maintenance of intracellular pH and to acidify and thereby vascularise and immune-suppress the TME. In normoxia, EGLN1-3 hydroxylate proline residues of HIF1A for its subsequent ubiquitination by the VHL-complex resulting in degradation and repression of its target genes.

#4216 Immunohistochemical analysis for galectin-3 and outcomes in medullary thyroid cancer

Introduction: Galectin-3 (Gal-3) is a beta-galactoside involved in multiple biological and pathological processes including growth and differentiation, cellular adhesion and transformation, and metastatic potential.
