#4645 Radio-guided surgery in use for treatment of early relapse in small intestine neuroendocrine tumours

Introduction: Surgery is the only definitive therapy for neuroendocrine tumours (NET). In number of small intestine NET first symptom is ileus or perforation, lifesaving surgical procedures applied. Such cases have significant risk of recurrence.

#4502 Molecular analysis of non-functioning PanNETs of the alpha lineage reveals new subtypes and mechanisms of progression

Introduction: Most pancreatic neuroendocrine tumours (PanNETs) are non-functioning. Previously, we demonstrated that small, MEN1-only mutated α-like PanNETs can be distinguished from larger ADM (mutated in ATRX, DAXX and MEN1) PanNETs based on epigenetic profiles. ADM PanNETs have shorter disease-free survival and a higher relapse risk. However, their therapeutic responses vary, underscoring group heterogeneity. ADM PanNETs remain insufficiently characterised, with potential subtype-specific progression drivers with implications for treatment choice and clinical outcome.

#4473 Somatostatin analogue delayed the recrudescence of stomach NET: A real-world study

Introduction: Type 1 gastric NENs (g-NENs) are common and relapse easily. Somstostatin analogues (SSAs) can inhibit gastrin secretion and cell proliferation. While the usage of SSAs in g-NENs is still controversial.

#4413 Efficacy and safety of adjuvant peptide receptor radionuclide therapy after curative surgery of locoregional limited small intestine neuroendocrine neoplasia (APSIN) – A multi-centre, prospective, randomised, controlled, phase III study

Introduction: Our multi-centre, prospective, open-label, two-arm parallel group, randomised, controlled, phase III study will address the efficacy and safety of adjuvant peptide receptor radionuclide therapy after curative surgery of locoregional limited small intestine neuroendocrine neoplasia.

#4282 A first-in-human phase I trial with antibody drug conjugate ADCT-701 in neuroendocrine tumours and carcinomas

Introduction: Neuroendocrine neoplasms (NENs) consist of neuroendocrine tumours and neuroendocrine carcinomas, which are rare malignancies found in various anatomical sites, including the gastrointestinal tract, pancreatic islets, lungs, and adrenal glands. Poorly differentiated NECs are classified as high-grade carcinomas that bear resemblance to small-cell lung cancer; however, these patients experience a high risk of relapse and demonstrate a limited response to additional systemic therapies. Adrenocortical carcinoma (ACC) is another rare cancer and currently, no targeted therapies have demonstrated significant effectiveness for this condition. Preclinical investigations have indicated that Delta-like non-canonical notch ligand 1 (DLK1) is expressed in various neuroendocrine neoplasms, including ACC, SCLC, neuroblastoma, pheochromocytoma, and paraganglioma.
