Pancreatic Neuroendocrine Tumors (PNETs): Role of Endoscopic UltraSound-Fine Needle Aspiration (EUS-FNA) and Accuracy of Ki-67 Measurement on Cytological Specimens Abstract #859

Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.
Aim(s): To report our experience, to describe the feasibility of measurement of Ki-67 on cytological samples, to evaluate its accuracy if compared with the Ki-67 measurement on surgical specimens.
Materials and methods: Retrospective analysis of all cases of pNETs diagnosed by means of EUS-FNA from August 2003. Cytological Ki-67 expression was compared with definitive surgical Ki-67 results.

#896 Grading of Metastases in Digestive Neuroendocrine Tumors (NET): Interest for Clinical Management?
Introduction: Therapeutic strategy of NETs is highly dependent on tumor classification according to the WHO system. NETs are frequently classified based on the histological characteristics of the primary tumor associated with the ENETS grading, even for patients with metastases.

#518 CK19 and KIT Immunostaining is a Useful Adjunct to Ki-67-Based Grading of Pancreatic NET: A Study on Matched Cytological and Histological Samples
Introduction: Pancreatic neuroendocrine tumors (NET) are rare neoplasms. Recent evidence suggests that Ki-67 staining predicts their behavior. Even more recently, a prognostic role has been proposed also for CK19 and KIT. This panel might guide patient management. CK19 and KIT have not yet been evaluated on NET on Fine needle aspiration samples (FNAs).

#3036 Can Ki-67 with 5.5% Be Better in Predicting Prognosis for Well Differentiated Pancreatic Neuroendocrine Tumors?
Introduction: Pancreatic neuroendocrine tumors (NETs) are rare malignancies, Ki-67 is a cell proliferation marker that has been shown to have some utility in predicting prognosis of neuroendocrine tumors. However, the ideal grading method for G1/G2 remains controversial.

#1104 Interlaboratory Variability of MIB1 Staining in Well Differentiated Pancreatic Neuroendocrine Tumors
Introduction: In neuroendocrine tumors (NET) grading and staging are the only routinely performed procedures to judge prognosis. Proliferation index using MIB1 staining has been introduced to assess grading. There are discussions on cut-off definitions, automated counting and inter-observer variability.
