#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.

#4593 Excellent response to Ac-225 DOTATATE therapy in a patient with small cell lung cancer

Introduction: Peptide receptor radionuclide therapy (PRRT) is a validated treatment for patients with NETs overexpressing somatostatin receptors (SSTR). IHC analysis indicates that up to 50% of small cell lung cancer (SCLC) tumours are SSTR2 positive and thus can be targeted by SSR imaging and PRRT. Therapy with α-emitting radionuclides, such as Ac225, may offer several advantages over β-emitters by having higher energy transfer and more effective cancer cell death.

#4577 Diagnosis of a cervical carotid paraganglioma: A case report and review of diagnostic imaging approaches

Introduction: Cervical paragangliomas are rare, often non-secreting tumours of neuroectodermal origin. Their diagnosis can be challenging due to the variability of clinical presentations and the diagnostic tests required.
