The Relation Between GEP-NEN Prognosis Re-Stratification and Ki-67 Variability: From a Single Institution Study Abstract #1397

Introduction: Ki-67 has been identified as a prognostic factor for GEP NEN.The variability of Ki-67 during the disease course has been reported,but there's few about its effects on prognosis.
Aim(s): We sought to study the association between Ki-67 variations and prognosis via survival re-stratification with one institution cohort.
Materials and methods: A total of 225 patients were enrolled in our cohort, We revised the survival classification on Ki-67 index (decision tree), and evaluated the patients with primary and metastasis specimens, compared the survival of Ki-67 variable group and those not (Kaplan –Meier method).

#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.

#2037 Stromal Immune Contexture Predicts Disease-Free Survival in Gastro-Entero-Pancreatic Neuroendocrine Neoplasms (GEP-NENs)
Introduction: Stromal Immune Contexture (SIC) helps predict prognosis in solid Tumors (T) but has been poorly investigated in gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs). We tested whether GEP-NENs profiling for adaptive immunity-related SIC markers, as well as inflammatory (COX2),EMT [Beta-catenin (B-cat)] and oncogenic pathway signaling (pS6) markers,could improve Ki67 and/or MO-based prediction of OS and DFS.

#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.

#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.
