#3246 Baseline albumin and neutrophil-to-lymphocyte ratio as predictive biomarkers of response to platinum-based therapy in patients with highly proliferative neuroendocrine carcinomas

Introduction: Neuroendocrine carcinomas (NECs) with ki-67/MIB1>55% show different responses to platinum-based therapy. Loss of Rb protein and KRAS mutation are markers of response, but it is unknown whether also clinical factors may have a predictive role.

#1148 Ki67 as a Prognostic Marker in Neuroendocrine Tumours: A Systematic Review of the Literature and Quantitative Synthesis of 5 year Survival Data

Introduction: The ENETS guidelines classify Gastroenteropancreatic Neuroendocrine Tumours (GEP NETs) according to the histological assessment of tumour mitotic count or Ki67 labelling index (LI) on paraffin-embedded tissue, because proliferation rate has been shown to strongly correlate with prognosis. Since the guidelines were published, Ki67 has been established as the more reproducible measure, and further large case series have been reported.

#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.

#645 Loss of Succinate Dehydrogenase (SDHB) in Midgut Carcinoids as Prognostic Factor: A New Marker of Personalized Cancer Medicine in Neuroendocrine Tumors?

Introduction: Gene mutations of the succinate dehydrogenase (SDH) complex are involved in the pathogenesis of cancer cells and play a pivotal role in angiogenesis and cell proliferation. The immunoistochemical (IHC) loss of SDHB is a marker of malignancy in pheocromocytomas and paragangliomas.
