#3057 Epidemiological Features of Patients with NeuroEndocrine Neoplasms (NENs): Preliminary Results of an Observational Study by the Hellenic Society of Medical Oncology (HeSMO)

Introduction: NENs are rare tumors and can grow in almost all tissues. Regardless histological, molecular and imaging characteristics that are indicative of the primary origin, a significant percentage remain of unknown primary.

#2683 Clinicopathological Features and Prognostic Analysis of 227 Cases with Well-Differentiated Gastric Neuroendocrine Tumors

Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a group of rare tumors with a strong heterogeneity, subdivided as well-differentiated neuroendocrine tumors (NETs, type 1-3 g-NETs) and poorly-differentiated neuroendocrine carcinoma(NECs). WHO classification(2019) for digestive system tumours has carried out a new classification and grading criteria for NENs of the gastrointestinal tract recently, there is very few relevant clinical data based on this new classification, especially for gastric NETs(g-NETs).
