#4650 Whole exome sequencing in pulmonary neuroendocrine neoplasms: Findings from a pilot investigation

Introduction: The molecular landscape of lung neuroendocrine tumours (NETs) is still poorly characterised. Lung NETs main prognostic factors currently include stage, histotype, grade, location, and demographic parameters, but molecular biomarkers are still not available, limiting the possibility for personalised therapeutic strategies.

#4619 Targeted beta- plus auger and conversion electron therapy with terbium-161 labelled somatostatin receptor antagonist DOTA-LM3 – BETA plus phase 0 study

Introduction: Radioligand therapy with lutetium-177 labelled somatostatin receptor (SSTR) agonists (177Lu-DOTATATE or 177Lu-DOTATOC) showed limited response rate and durability. The novel SSTR antagonist DOTA-LM3 labelled with terbium-161, which co-emits conversion and Auger electrons in addition to β- particles, potentially increasing tumour doses and offering a more effective treatment for micro metastases.

#4594 RNA splicing as a key regulatory player with translational potential in pulmonary neuroendocrine neoplasms (lungNETs)

Introduction: Neuroendocrine tumours (NETs) are a diverse group of neoplasms arising from neuroendocrine cells. Within this group, lung neuroendocrine tumours (LungNETs) represent one of the most frequent subtypes of NETs. LungNETs are classified by grade, according to their proliferative index and aggressiveness. Among them, typical carcinoids (G1) and atypical carcinoids (G2) are the lowest grade subtypes. While these tumours are less aggressive, they remain underexplored compared to higher-grade subtypes, highlighting the need for molecular studies to improve clinical approaches. In this context, previous studies have shown that abnormalities in the splicing machinery are frequent in tumour pathologies and also occur in LungNETs.

#4499 Impact of early molecular tumour board inclusion on treatment outcomes in neuroendocrine neoplasms: A retrospective double-centre study

Introduction: The treatment of neuroendocrine neoplasms (NENs) is particularly challenging due to the limited availability of standard therapies. While personalised approaches are revolutionising many areas of oncology, their progress in the field of NENs has been comparatively slower. The integration of molecular tumour boards (MTBs) into clinical practice represents a major advance in oncology, even for rare entities such as NENs.

#4469 Therapeutic strategy for pancreatic neuroendocrine tumours: An overview of the TNE West Network (2016-2024)

Introduction: Neuroendocrine tumours (NETs) are relatively rare and often diagnosed at an advanced stage, typically occurring between the ages of 40 and 60. They primarily manifest in the gastrointestinal system, pancreas, bronchi, lungs, thymus, and thyroid.
