The need of centralisation for small intestinal neuroendocrine tumor surgery – A cohort study from the GTE-Endocan-RENATEN Network, the CentralChirSINET study

#3743

Introduction: The concept of surgical centralization is more and more generalized for specific surgical procedure. Small intestinal (SI) neuroendocrine tumor (NET) surgical resection is well standardized and is the cornerstone of the curative care.

Aim(s): The aim of the study was to evaluate the relationship between procedure volume and the optimal surgical SI-NET resection.

Materials and methods: We conducted a retrospective national study including patients who underwent SI-NET resection between 2019 and 2021. High volume center (hvC) was defined as more than five SI-NET resection per year. We evaluate the quality of surgical resection between high and low volume center (lvC) by comparing the lymph node (LN) resection as primary endpoint (64 patients in each arm were required to show a difference from 70% in lvC to 90% in hvC of LN≥8).
