Two Separate Modified ENETS Staging Classifications Are Needed for Duodenal and Jejunoileal Neuroendocrine Neoplasms

#1662

Introduction: Previous studies showed duodenal neuroendocrine neoplasms (d-NEN) and jejunoileal NEN (j-NEN) harboring different features. However, the staging classifications of d-NEN and j-NEN proposed by ENETS are identical.

Aim(s): To compare the clinicopathological features between d-NEN and j-NEN and investigate the prognostic validity of ENETS staging classifications.

Materials and methods: 1076 d-NENs and 2941 j-NENs patients were retrieved respectively from Surveillance, Epidemiology, and End Results (SEER) cancer registry. Disease-specific survival was used as the main outcome.
