#4654 Usefulness of soluble tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptors R2 and R3 in progression assessment of gastroenteropancreatic neuroendocrine neoplasms – A preliminary study

Introduction: TRAIL is a member of TNF family and appears in membrane and soluble (s) forms. It acts either triggering (R1 and R2) or blocking (R3 and R4) apoptosis. TRAIL targeted therapy is widely studied and known as potentially effective in number of neoplasms.

#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).

#4642 Establishing a standardised histopathological grading system for mesenteric fibrosis in small intestinal neuroendocrine tumours

Introduction: Mesenteric fibrosis (MF) frequently develops around mesenteric metastasis in small intestinal neuroendocrine tumour (SI-NET) patients. Since MF is not always detected radiologically, histopathological examination is considered the gold standard. However, there is no uniform histopathological scoring system for MF correlated with clinical data.

#4628 Triple negative breast neuroendocrine carcinoma in older patient: A rare entity

Introduction: Neuroendocrine breast carcinoma is a rare histological form of breast cancer, that represent 0.1% of all breast cancers and is recognised by the World Health Organization as a distinct entity. Characterised by a non-specific clinical and radiological presentation. Therapeutic management is not codified and is usually superimposed on that of classical breast cancer.
