#2977 Predicting Survival in Patients with a Neuroendocrine Tumor of the Small Intestine (SI-NET)

Introduction: SI-NET comprise the largest group of neuroendocrine tumors. Because of their heterogeneity, predicting survival has proven challenging. A nomogram (NG) to assess SI-NET disease specific survival (DSS) has been developed in 2010 by Modlin, et al. based on analysis of retrospective data from the Surveillance, Epidemiology and End Results (SEER) database.

#1881 A Gene Expression-Based Nomogram Predicts Progression Free Survival in Small Bowel NETs

Introduction: Nomograms are predictive tools that help prognosticate. A survival nomogram has been validated for small bowel NETs. A circulating NET specific 51gene signature – the NETest – has efficacy (~95%) as a predictor of progression free survival (PFS).

#1485 Validation of a Blood Neuroendocrine Tumor Gene Signature, the NETest, in a Netherlands NET Cohort

Introduction: The CgA has limitations as a monoanalyte biomarker. The introduction of a PCR-based multi-analyte analysis of 51 genes (NETest) has been proposed as more accurate.

#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.

#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.
