#4541 Prognosis analysis of metastatic rectal neuroendocrine tumour: Liver-directed trans arterial embolisation may play a pivotal role

Introduction: Rectal neuroendocrine tumour (rNET) is prone to metastasis, and distant metastasis is associated with worse prognosis. However, factors influencing the prognosis of metastatic rNET and the recommended treatments remain controversial.

#3704 Impact of surgical approach on short- and long-term outcomes in gastroenteropancreatic neuroendocrine carcinomas

Introduction: Complete resection is the cornerstone of curative-intent treatment for gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs) without distant metastases. However, there is a paucity of data on the impact of recent advancements in minimally invasive surgery (MIS), such as the utilization of laparoscopic and robotic approaches, on GEP-NEC patients’ outcomes.

#3703 Impact of primary tumor resection and metastasectomy among gastroenteropancreatic neuroendocrine tumors with liver metastases only on survival

Introduction: The incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is increasing globally, and the patients are often diagnosed with synchronous liver metastases. Despite recommendations for primary tumor resection (PTR) with or without liver resection (LR) in the patients, there are conflicting data for their impact on overall survival (OS).

#3701 Primary tumor resection improves survival of gastrointestinal neuroendocrine carcinoma patients with non-resected liver metastases

Introduction: The role of primary tumor resection (PTR) in the survival of gastrointestinal neuroendocrine carcinoma (GI-NEC) patients with liver metastases only remains poorly defined.
