#4566 Predictive value of high-risk histopathological- and molecular criteria for lymph node metastasis in appendiceal neuroendocrine tumours

Introduction: Appendiceal neuroendocrine tumours (aNET) are rare neoplasms for which consensus is needed for follow-up and additional treatment. To unravel the factors behind aNET which showed lymph node metastasis (LNM) in additional right hemicolectomy (RH), we evaluated high-risk histopathological parameters in aNETs and studied molecular parameters.

#4236 Do metastatic appendiceal NETs ever develop metachronously after appendectomy or right hemicolectomy?

Introduction: Appendiceal NETs are typically detected incidentally during appendectomy. A recent study reported no cases of metachronous metastases among patients (pts) with primary tumors

#3385 Review of appendiceal neuroendocrine neoplasms and pathological features that influence decision for oncological right hemicolectomy

Introduction: Appendiceal neuroendocrine neoplasms (NEN) are typically an incidental finding with 80% diagnosed post-appendectomy in the setting of acute appendicitis. While ENETS recommends that patients with appendiceal NEN >2cm undergo right hemicolectomy (RH) there is uncertainty in how to manage those measuring 1-2cm.

#2950 Hemicolectomy for Neuroendocrine Neoplasms of the Appendix - Is It Really Necessary?

Introduction: Appendical neuroendocrine neoplasms (ANENs) are rare. Limited data is available regarding prognosis and optimal treatment strategy in those tumors

#2255 When Is Right Hemicolectomy Really Indicated for Pediatric Appendiceal NETs?

Introduction: Pediatric NET of the appendix (ANET) are rare tumors with unknown real incidence.For pediatric age initial staging procedures are not standardized and guidelines for pediatric patients with ANET do not exist.
