#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.

#2938 Rectal Neuroendocrine Tumor with Concomitant Erdheim-Chester Disease: A Rare Case Report

#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.
