#332 Impact of Baseline Ki-67 index and Other Baseline Characteristics on Outcome in a Study of Sunitinib (SU) for the Treatment of Advanced, Progressive Pancreatic Neuroendocrine Tumor (NET)
Introduction: Baseline Ki-67 index and other characteristics may influence outcome in patients (pts) with pancreatic NET; however, the value of Ki-67 and others have not been evaluated prospectively in trials.

#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.

#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.

#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.

#696 Downgrading Due to Ki-67 Index Assessment with Image Analysis
Introduction: The latest WHO classification for neuroendocrine tumors (NET) defines their grade according to Ki-67 and mitotic index. These parameters have both shown to be prognostic.

#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.

#961 Heterogeneity in the Ki-67 Index of Neuroendocrine Tumors
Introduction: Tumor heterogeneity due to tumor evolution is becoming more widely recognised. Neuroendocrine tumors (NET) are routinely graded using the Ki-67 index based on a single tumor location, however, this could lead to undergrading if the Ki-67 index is higher at the metastatic site.

#697 Grading NET: Mitosis and Ki-67 conditio sine qua non?
Introduction: The latest WHO classification for neuroendocrine tumors (NET) defines their grade according to Ki-67 and mitotic index. However, as both parameters are markers for a different part of the cell cycle, their values might not lead to the same grade.

#737 Impact of Ki-67 Proliferative Index on Survival in Patients with Typical and Atypical Pulmonary Carcinoids
Introduction: Currently pulmonary carcinoids are separated into typical and atypical tumors based on mitotic count and presence of necrosis, according to the WHO classification. Whereas for GEP NETs the ENETS Guidelines have been incorporated into the WHO classification and grading is based on mitotic counts and Ki-67 index, the use of the Ki-67 index for grading pulmonary carcinoids is still under debate.

#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.
