#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.

Introduction: Since WHO 2010, resected pNETs are graded as G1, G2 or G3 using the Ki67-LI. EUS-FNA is often used for diagnosis but few studies have assessed its value for grading.
