#4647 Crosstalk between cancer-associated fibroblasts and small intestinal neuroendocrine tumour cells in a 3D spheroid model

Introduction: At diagnosis, over 50% of small intestinal neuroendocrine tumours (SI-NETs) have metastasised to the mesentery where they often induce extensive fibrosis. Recent studies highlight the crucial interaction between SI-NET cells and cancer-associated fibroblasts (CAFs) in the pathogenesis of mesenteric fibrosis (MF).

#4576 Economic evidence for pancreatic and extra-pancreatic neuroendocrine tumours following treatment failure or disease progression: A systematic literature review

Introduction: Treatment failure and disease progression (PD) in neuroendocrine tumours (NETs), a rare group of malignancies, are common due to limited targeted treatments.

#4572 Steroid dosing to prevent tumour flare reaction with 177Lu-DOTATATE

Introduction: Tumour flare reactions including increased pain and small bowel obstruction (SBO) have been reported in patients with somatostatin receptor (SSTR)-positive gastroenteropancreatic neuroendocrine tumours (GEP-NETs) receiving 177Lu-DOTATATE. Retrospective reviews report tumour flare reactions in 6 to 40 percent of high-risk patients receiving 177Lu-DOTATATE and report success with using corticosteroid prophylaxis to prevent tumour flare recurrence with subsequent doses of 177Lu-DOTATATE (Strosberg, et al., 2021; Salner, et al., 2020).

#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.
