#4407 Characterisation of patients with neuroendocrine tumours in a specialised care institution in oncological endocrinology Bogotá, Colombia

Introduction: Neuroendocrine tumours (NETs) are heterogeneous malignancies that arise from the diffuse neuroendocrine system. Its incidence has increased in the last 3 decades. They have a relatively indolent growth rate and are capable of secreting peptide hormones and biogenic amines.

#4031 68-Gallium DOTANOC PET/CT pitfall in adnexal tumor

Introduction: PET/CT with 68Ga-DOTA is a commonly used tool in the baseline evaluation and follow-up of NETs due to its high specificity and sensitivity, showing better performance than CT in detecting primary and metastatic disease. However, we must know more about its normal physiological distribution, its variation in pathologies, and the possibility of confusion with benign processes to optimize its interpretation.

#3257 Molecular and functional study of somatostatin receptors in pheochromocytomas and paragangliomas

Introduction: Most pheochromocytomas (PCC) and paragangliomas (PGL) are benign neuroendocrine tumors that overproduce catecholamines causing hypertension, arrhythmia, and stroke; however, 10 30% may present distant metastasis. About 40% are caused by germline mutations, which may be classified in 3 different clusters. PCC/PGL diagnosis involves blood/urine tests and imaging techniques, while their treatment often requires distinct pharmacological and surgical approaches. Thus, identification of new biomarkers for early diagnosis, and progression/response would help to avoid unnecessary tests and enable personalized medicine approaches.

#1772 Expression of Truncated Functional Subtype 5 Somatostatin Receptor Variant (sst5TMD4) in GEP-NETs and Association with Relevant Pathways Involved in NET Tumorigenesis

Introduction: Sst5TMD4, which is derived from a non-canonical splicing process of sst5 receptor, is overexpressed in several endocrine tumors and associated with a worse prognosis.
