#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.

#2953 Temporal Trends in Incidence, Presentation and Work-Up of Neuroendocrine Neoplasms of the Appendix

Introduction: Although temporal trends in incidence and prognosis of neuroendocrine neoplasms have been described in the literature, data regarding trends in Appendiceal Neuroendocrine Neoplasms (ANENs) is limited.

#2057 Morphological Factors Related to Nodal Metastases in Neuroendocrine Neoplasms of the Appendix. A Multicenter Retrospective Study

Introduction: Appendiceal NETs are usually diagnosed accidentally after appendectomy; the indications for right hemicolectomy are currently based on several parameters (tumor size, grading, Ki-67, localization, mesoappendiceal invasion, lympho-vascular infiltration). Available guidelines are based on scarce evidence inferred by small, retrospective, single institution studies.
