#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).

#4563 Clinical case of a young woman with acromegaly, hyperprolactinemia and pituitary tumour with mixed morphology of adenoma and gangliocytoma

Introduction: Acromegaly is a rare disorder that develops due to persistent hypersecretion of somatotropic hormone in adults after closure of the growth plates. In the majority of cases, the cause is a pituitary adenoma.

#4496 ATRX, DAXX, and menin immunohistochemistry identify prognostic relevant non-functioning neuroendocrine tumours subgroups

Introduction: Non-functioning pancreatic neuroendocrine tumours (NF-pNETs) are rare tumours with a variable prognosis. Recent studies have identified prognostic subgroups based on ATRX, DAXX and MEN1 mutations along with chromosomal aneuploidies.

#4281 Automated (artificial intelligence) vs. manual evaluation of the somatostatin-receptor 2A and proliferation marker Ki-67 in neuroendocrine neoplasms: A pilot study

Introduction: Digital image analysis methods are currently being equipped with artificial intelligence (AI). Various AI applications are already in use to determine Ki-67. To date, there is no specialised AI application available to determine the somatostatin-receptor 2A (SSTR2A).
