#4612 Intraoperative beta-probe for pathological tissue detection in GEP-NET patients: A prospective phase II trial

Introduction: Accurate localisation of gastroenteropancreatic neuroendocrine tumours (GEP-NET) is essential for successful radical surgery. Radio guided surgery (RGS) is an innovative technique that may enhance lesion detection.

#4583 Improved assessment of gene rearrangements by targeting non-coding DNA regions in patients diagnosed with pancreatic neuroendocrine neoplasms

Introduction: Whole-genome sequencing projects documented the heterogeneity of pancreatic neuroendocrine neoplasms (PanNEN), while showing that few core pathways are consistently affected in their tumorigenesis. Comprehensive genomic profiling (CGP) of real-world cases is expected to recapitulate such heterogeneity for patient stratification and to inform precision therapy. While coding DNA is the focus of current CGP panels, the potential of targeting non-coding DNA (ncDNA) to improve structural variants detection has not been widely explored in this context.

#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.

#4555 Assessment of gastric mucosa conditions changes in patients with gastric neuroendocrine neoplasia type 1 during gastroprotective therapy

Introduction: Currently, the incidence of gastric neuroendocrine neoplasia (gNEN) has increased significantly. Most gNEN are developed on the background of chronic atrophic gastritis (about 90%). Despite this, the role of chronic atrophic gastritis treatment (gastroprotective therapy) in dynamic of gNEN remains unexplored.

#4500 Effectiveness of palbociclib plus letrozole as first line therapy of metastatic breast neuroendocrine carcinoma: A case report

Introduction: Palbociclib plus endocrine therapy is the standard treatment of advanced luminal breast cancer. However, we lack data on its effectiveness in breast neuroendocrine carcinoma (NEC).
