#4592 Uncovering cell-state heterogeneity in large-cell panNEC indicates potentially targetable aberrant brain type neuronal de-differentiation

Introduction: Classification and treatment of high-grade pancreatic neuroendocrine carcinoma (panNEC), particularly those with large-cell morphology, present significant clinical challenges due to considerable inter- and intra-patient tumour heterogeneity.

#4544 Spatial and temporal intratumour heterogeneity of pancreatic neuroendocrine tumours (PanNET)

Introduction: Data derived from the study of intertumour heterogeneity have led to propose that PanNET evolution may start either from beta cells with good prognosis, or from alpha cells with sequential alterations of MDA (MENIN-DAXX/ATRX) leading to more aggressive lesions.

#4383 Clinical and biological heterogeneity of grade 2 gastroenteropancreatic neuroendocrine neoplasms (GEP NENs): Prognostic significance of the 10% Ki-67 index cutoff and implications for treatment strategies

Introduction: Gastroenteropancreatic neuroendocrine neoplasms (GEP NENs) are a diverse group of neoplasms with varying prognoses. Grade 2 (G2) tumours, with a Ki-67 index between 3%-20%, present management challenges due to their intermediate behaviour, with evidence suggesting distinct outcomes between Ki-67

#4285 Predictive biomarkers for immunotherapy efficacy in neuroendocrine neoplasms

Introduction: The application of immunotherapy in NENs is still in its early stages. Identifying reliable predictive biomarkers of efficacy is critical for research, enabling better selection of patients who are more likely to respond to immunotherapy and improving treatment success rates.

#3002 Quality of Life, Tumour Heterogeneity and Biomarker Levels in Patients with Progressive Pancreatic or Midgut Neuroendocrine Tumours: Baseline Data from CLARINET FORTE

Introduction: Lanreotide autogel (LAN) 120 mg every (q)28 days (standard regimen) improves progression-free survival vs placebo in patients with advanced, somatostatin receptor-positive (SSTR+) gastroenteropancreatic neuroendocrine tumours (NETs).
