Usefulness of the WHO Classification and of the ENETS TNM Staging System to Predict Prognosis in Patients with Rectal NENs Abstract #955

Introduction: WHO classification and TNM staging system have been proposed for rectal neuroendocrine neoplasia (NENs). However, their prognostic accuracy is not validated yet.
Aim(s): Assess the ability of WHO classification/ENETS TNM staging system to predict survival of patients with rectal NENs.
Materials and methods: Retrospective analysis of patients with rectal NENs referred to the Beaujon Hospital (Clichy, France) and the S. Andrea Hospital (Rome,Italy) from 1990 to 2013.

#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.
