#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia

Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.

#2943 Risk Stratification of Well-Differentiated Rectal Neuroendocrine Tumors

Introduction: How to screen patients with well-differentiated rectal neuroendocrine tumors (NETs) who had high risk to develop metastatic disease and poor survival was still less cleared.

#2844 Rectal Neuroendocrine Tumor with Chromogranin Expression Is Associated with Aggressive Clinical Behavior and Worse Prognosis

Introduction: Although rectal neuroendocrine tumors (NETs) with L-cell phenotype and small tumor size generally had better clinical behavior, the new 2019 WHO classification classified all rectal NETs are malignant without considering L-cell phenotype and small tumor size. Therefore, identifying biomarkers of rectal NETs is important to stratify the clinical behavior of rectal NETs.

#2762 Finding the Risk Factors Associated with Neuroendocrine Tumors of Rectum

Introduction: Neuroendocrine tumors usually exhibits aggressive clinical behaviour and exclusive histopathological features. 60 to 70% of rectal NETs are asymptomatic.

#2714 The Clinical Outcome of Non-Curative Resection of Small Rectal Neuroendocrine Tumours

Introduction: Small rectal NETs are thought to be less aggressive and relatively benign. However, lymphovascular invasion(LVI) or positive margin after endoscopic resection(ER) was noticed in small rectal NETs.
