#3465 Opposite treatment approach in two institutes identifies primary tumor resection to be associated with improved disease specific mortality in patients with stage IV small intestinal neuroendocrine tumors (SI-NET) vs watch-and-wait strategy

Introduction: SI-NET often present with metastatic disease. There is an ongoing debate whether or not to perform primary tumor resection (PTR) in stage IV SI-NET.

#3457 Relevant prognostic factors in patients with stage IV small intestine neuroendocrine neoplasms

Introduction: There are only few, but controversial data on the prognostic role of upfront primary tumor resection and mesenteric lymph node dissection (PTR) in patients with stage IV small intestinal neuroendocrine neoplasia (SI-NEN).

#3456 Clinicopathological characteristics and treatment options of the new grade 3 neuroendocrine tumor subgroup (NETs G3)

Introduction: NET G3 is a new subgroup of well-differentiated NENs. The impact of morphological characteristics on clinical course and treatment tactics is still questionable.

#683 Liver Resection Experience for Metastatic Small Bowel NETs, a Single Center Experience

Introduction: Over the last two decades, the role of surgery in the management of small bowel NETs (SBNET) has evolved. There is growing evidence supporting the role of liver resection for metastatic disease.

#126 Assessment of the proliferation marker Ki-67 by endoscopic ultrasound guided-Fine Needle Aspiration (EUS-FNA) in pancreatic endocrine tumors: A comparative analysis with histology of the surgical specimen

Introduction: Assessment of the proliferative index by Ki-67 immuno-labelling is an important prognostic parameter for the biologic behavior of digestive neuroendocrine tumors, usually established on the histological specimen obtained after surgery or macro-biopsy. However, small pancreatic endocrine tumors (PET) are more and more often recognized by CT/MRI and diagnosed by EUS. The value of Ki-67 labelling index (Ki-67-LI) on fine needle aspiration (FNA) is not well-established in this setting, although regularly assessed.
