#4571 Characterisation and prognostic impact of carcinoid syndrome in bronchial neuroendocrine tumours

Introduction: Metastatic bronchial neuroendocrine tumours (MBNET) are associated with carcinoid syndrome in 10 to 40% of cases. Characteristics of carcinoid heart disease (CHD) are poorly described.

#4456 Characteristics and clinical outcomes after endoscopic or surgical resection of localised sporadic type III gastric NETs: A national study from the French Group of Endocrine Tumors and ENDOCAN-RENATEN network

Introduction: Type III gastric neuroendocrine tumours (gNETs) are rare indolent tumours with increasing incidence. Endoscopic resection has recently been described to be a safe strategy to remove small, localised type III gNETs.

#4454 Impact of pathological review of neuroendocrine neoplasms (NENs) within the French national ENDOCAN/TENpath network

Introduction: NENs are rare tumours which can benefit from specialised pathological assessment. In France, the ENDOCAN/TENpath network, composed of 33 expert pathologists in 20 centres, provides consultations (2nd readings) at the request of non-specialist pathologists. Challenging cases are reviewed in monthly virtual meetings grouping all expert pathologists (third readings).

#4304 Co-targeting the Endocannabinoid System (ES) and mTOR in NEN potentiates their anti-tumour effect via unique metabolic changes

Introduction: The current treatment of neuroendocrine neoplasms (NEN) has limited efficacy, highlighting the need for novel therapeutic approaches. We have previously shown the potential therapeutic benefit when combining ES blocking with Everolimus (Eve).

#3743 The need of centralisation for small intestinal neuroendocrine tumor surgery – A cohort study from the GTE-Endocan-RENATEN Network, the CentralChirSINET study

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.
