#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.

#4559 Exploring the interplay between RNA methylation and splicing dysregulation in neuroendocrine tumours

Introduction: Post-transcriptional modifications play crucial roles in regulating gene expression and cellular function. While recent findings indicate that alternative splicing dysregulation plays a key role in tumorigenic properties of neuroendocrine tumours (NETs), the role of other RNA processing mechanisms, such as N6-methyladenosine (m6A) — being the most common RNA methylation — remains largely unexplored in NETs.

#4077 The importance of pathological sample review in the initial workup study in reference centers: The experience of an ENETS Center of Excellence

Introduction: Neuroendocrine neoplasms (NEN) are complex tumors managed in specialized centers with a multidisciplinary approach. Patients often provide diagnostic studies, including histological material. Pathology department review ensures proper classification, guiding therapies, and potential clinical trial inclusion.

#544 Second Primary Tumor in Patients with Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): Data From a Retrospective Observational Unicentric Study

Introduction: It is known that GEPNETs are associated with a high incidence of second primary tumors, especially in the context of inherited syndromes and synchronous injuries to the intestine.
