#813 Comparison of Manual and Automatic Methods of Ki-67 Proliferation Index for Neuroendocrine Tumors: The Development and Validation of a Novel Digital Pathology Tool (Ki-67Counter)
Introduction: Ki-67 proliferation index is an increasingly important biomarker used to grade neuroendocrine tumors. Manual counting methods are laborious and subject to inter- and intra-observer variability. Digital counting methods hold promise for fast and reproducible indices, however, they are fraught with technical difficulties.

#182 Ki-67 (MIB-1) Proliferative Activity and Beta-Catenin Immunoexpression in Liver Metastases of Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Assessment of liver metastases biology features associated with cell proliferation and adhesion has a strong prognostic impact in patients with gastroenteropancreatic (GEP) neuroendocrine carcinomas.

#9 Case Management of Metastatic carcinoid of the Foregut,Midgut and Hindgut:the relevance of Ki-67 prognostication
Introduction: The predictive value of tumor grade in the prognosis of carcinoid is insufficient and somehow misleading. The grade and differentiation in carcinoid tumors must be seen in conjunction with the Ki-67 index. The Ki-67 protein is a cellular marker for proliferation, present during all active phases of the cell cycle (G1, S, G2 and mitosis) and absent from resting cells (G0). It is therefore an excellent marker to determine the growth fraction of a given cell population. The Ki-67 labelling index is often correlated with the clinical course of carcinoid.

#70 The validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumor
Introduction: Carcinoid tumors of the appendix are rare and often discovered incidentally through appendectomy. Most are clinically benign but may be associated with metastatic disease. Ki-67, a nuclear protein structurally associated with chromatin, is an excellent marker for measuring cell proliferation and it has been shown to correlate with the outcome in pancreatic and ileocecal carcinoids.

#251 Ki-67 is a Better Prognostic Marker than Mitotic Count in Neuroendocrine Tumors
Introduction: The recent classification system proposed by ENETS assigns grade by Ki-67 index +/- mitotic count. It has been adopted into routine practice but there is limited data on the relationship between them.

#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.

#845 Ki-67 Index as a Biomarker of Response to Cytotoxic Chemotherapy
Introduction: Chemotherapy (CT) is widely used for neuroendocrine tumors (NET) but there are no validated biomarkers to predict response. The Ki-67 proliferation index has been proposed as a means of selecting patients for CT but robust data are lacking.

#2276 Ki-67 to Predict Recurrence and Survival of Pancreatic Neuroendocrine Tumors
Introduction: Despite evidence of different malignant potential, postoperative follow-up is similar for G1 and G2 pancreatic neuroendocrine tumors (panNET) and adjuvant treatment is currently not indicated.

#138 The use of F-18-FDG-PET for patients with neuroendocrine tumors
Introduction: Neoplastic tissue exhibits high glucose utilization, which can be imaged by 18F-Fluorodeoxyglucose-positron emission tomography (FDG-PET). Whether FDG-PET is useful for neuroendocrine (NE) tumors, however, is questionable, due to the slow growth rate often observed in these tumors.

#2175 A Retrospective Analysis of 344 Cases with Neuroendocrine Neoplasms
Introduction: Ki-67 is a nuclear protein that is strictly associated with cellular proliferation,acting as a cellular marker for proliferation in clinical practice to determine the degree to which the tumor cells are duplicating. Ki-67 index strongly ties to the prognosis and provides guiding significance to clinical decisions.
