The validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumor Abstract #70

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.
Aim(s): To examine the validity of Ki-67 as a prognostic indicator in patients with appendiceal carcinoid tumors.
Materials and methods: A retrospective chart review was conducted on 51 patients with appendiceal carcinoid tumors who underwent surgical intervention from 1991 – 2008. MIB-1, a monoclonal antibody of Ki-67 measuring its expression, was used to determine cell proliferation and correlated with clinical and histological parameters. MIB-1 index was categorized according to the WHO (World Health Organization) classification.

#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.

#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.

#1654 A Single Centre Analysis of the Management of Appendiceal Neuroendocrine Neoplasms (NENs) Including Goblet Cell Carcinoids (GCC)
Introduction: Appendiceal neuroendocrine neoplasms (NENs) are usually diagnosed incidentally on histology following an appendicectomy. They include carcinoid tumours (appendiceal neuroendocrine tumours, NETs) and goblet cell carcinoids (GCC). GCC neoplasms are able to transform to an adenocarcinoma phenotype.
