The Role of Plasma Chromogranin A as Assessment of Treatment Response in Grade 1-3 Non-Functioning Gastroenteropancreatic (GEP) Neuroendocrine Tumors Abstract #832

Introduction: Chromogranin A (CgA) is considered to be of value not only in diagnosis but also in monitoring the disease response to treatment. However, only a few studies have been published on this issue.
Aim(s): We investigated to evaluate whether biochemical response using plasma CgA level is in reliable concordance with the clinical response in grade 1-3 nonfunctiong gastroenteropancreatic neuroendocrine tumors (GEP-NETs) irrespective of chemotherapeutic agents.
Materials and methods: A total of 27 cases in 18 patients were enrolled in this study between March 2011 and September 2013. Twenty-seven cases were evaluated clinically and radiologically while serial CgA tests were also estimated during treatment.

#11 Plasma chromogranin - A response to octreotide test: Prognostic value for clinical outcome in endocrine digestive tumors
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) expressing somatostatin receptors may be treated with somatostatin analogues (SSAs). Selection criteria are a positive Octreoscan® or a >50% hormone level decrease after octreotide s.c. injection (octreotide test) (OT). Plasma chromogranin A (CgA) is the best general GEP-NET marker, but data on CgA response to OT are scant.

#29 Serum chromogranin A correlation with tumor burden in metastatic small bowel carcinoid patients
Introduction: Patients with neuroendocrine tumors may have clinical courses that range from fairly indolent to more aggressive. Cross–sectional studies, nuclear imaging and biochemical markers are often used to monitor disease progression. Optimal surveillance tests and intervals have not been firmly established. Studies suggest that chromogranin A (CgA) may be a surrogate marker for tumor burden.

#41 Immunohisochemical evaluation of EMT regulators, E- and N-cadherin in neuroendocrine Tumors of the Gastro-Entero-Pancreativ system
Introduction: Local tumor invasion represents the first step of the metastatic cascade of carcinomas, and requires changes in cell adhesion and migration properties of tumor cells. This biologic process is known as epithelial-mesenchymal transition (EMT). One key biochemical change associated with EMT is the loss of E-cadherin expression promoted by specific transcriptional repressors such as Snail, Slug, and Twist. Overexpression of EMT inducers increases other factors, such as FoxC2, although its role in EMT is poorly understood. Neuroendocrine tumors (NETs) of the gastroenteropancreatic (GEP) system, originated from the diffuse endocrine system, represent a heterogeneous group of tumors. Their prevalence has increased substantially over the past three decades, without substantial improvements in their clinical management, and their variable clinical course cannot be predicted by common clinicopathological parameters. Thus, new prognostic markers are urgently needed.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#67 Interest of combined chromogranin A and pancreatic polypeptide for diagnosis and follow-up of gastroenteropancreatic endocrine carcinoma
Introduction: Assessment of tumor burden changes is essential for the management of well-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEPNET). Chromogranin A (CgA) is the principal tumor marker for such tumors; however, its use to evaluate morphological tumor progression is not validated. Combined CgA and pancreatic polypeptide (PP) may increase sensitivity in the diagnosis of GEP-NET.
