#4667 Clinical outcomes in patients with typical (TC) and atypical bronchial carcinoids (AC): A 15-year retrospective study from an ENETS Center of Excellence

Introduction: Bronchial neuroendocrine neoplasms (NENs) can be subdivided into TCs, ACs and neuroendocrine carcinomas (NECs). Although a few studies have explored treatment approaches and oncological outcomes, most focus on surgical cohorts, small sample sizes, or mixed groups including TC, AC, and NECs. Real-life cohort data are lacking.

#4618 The exceptionally rare phenomenon of well-differentiated colon neuroendocrine tumours

Introduction: Colonic neuroendocrine tumours (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared to other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated NECs, leading to unclear data on prevalence, clinical behaviour, and prognosis of well-differentiated colonic NETs.

#4606 Neuroendocrine mess – Ectopic Cushing syndrome and severe hypokalaemia

Introduction: Cushing Syndrome (CS) is the condition resulting from hypercortisolaemia. Ectopic Cushing Syndrome (ECS) is responsible for up to 20% of all CS cases. Pancreatic neuroendocrine neoplasms (pNEN) are responsible for 10-20% of those cases.

#4557 miR-1290 and miR-320c regulate cell proliferation and predict patient prognosis in neuroendocrine carcinomas

Introduction: The biology of neuroendocrine carcinomas (NECs) remains largely unknown, limiting the use of biomarkers for patient stratification and therapy response prediction in clinical practice.

#4511 Sequencing chemotherapy and radiotherapy leading to complete remission in a patient with highly aggressive, advanced neuroendocrine cancer of unknown origin

Introduction: Neuroendocrine neoplasms arise from endocrine cells throughout the body, primary tumour may be localised in various organs. Neuroendocrine carcinoma (NEC) is very aggressive form of these tumours with survival limited usually to a few months despite oncological treatment.
