Affinity Proteomic Plasma Analysis of Human Well-Differentiated Small Intestinal Neuroendocrine Tumors Abstract #672

Introduction: Small intestine neuroendocrine tumor (SI-NET) patients get diagnosis at the stage of metastasis and there is a lack of curative treatments.
Aim(s): To detect specific, reliable and sensitive biomarker for early diagnosis and disease progression status.
Materials and methods: Human Protein Atlas antibodies (Ab) profiled proteomic signatures from SI-NET blood patients (p) and healthy controls (HC) using an antibody suspension bead array. Untreated patients (153 p) at different stages were divided into two cohorts: cohort 1 (20 HC and 57 p) and cohort 2 (36 HC and 96 p). Markers screening using 188 Ab on cohort 1 selected 20 antigens validated then on cohort 2. Selection was based on univariate and multivariate statistical significance together with the consistency between experiments.

#20 Paraneoplastic antigen Ma2 (PNMA2) auto-antibodies as biomarkers for early small intestine neuroendocrine tumors detection
Introduction: Small intestine neuroendocrine tumors (NETs) comprise well-differentiated NET (benign carcinoid), well-differentiated neuroendocrine carcinoma (malignant carcinoid) and poorly differentiated neuroendocrine carcinoma (NEC). The majority of NET patients have developed liver metastases at the time of diagnosis and surgery is then seldom curative. Novel predictive, diagnostic and prognostic markers are thus needed to improve our capabilities to diagnose and cure these tumors. We have previously identified six novel marker genes for neuroendocrine tumor cells by using Affymetrix microarrays and advanced bioinformatics. One of this markers, the paraneoplastic antigen Ma2 (PNMA2), which is normally expressed only in nervous tissue, can in the process of carcinogenesis be detected in tumors located outside the nervous system. The finding that Ma2 is expressed in small intestine neuroendocrine primary tumors and their metastases made it interesting to screen whether antibodies against Ma2 are present in the serum of NET patients.

#47 Plasma CCN2/connective tissue growth factor is associated with right ventricular dysfunction in Patients with Neuroendocrine Tumors
Introduction: Carcinoid heart disease (CHD) is a known complication of neuroendocrine tumors (NETs), particularly of those arising from the small intestine, appendix and proximal colon (previously known as mid-gut carcinoids). CHD is characterized by right heart fibrotic lesions and has traditionally been defined by the degree of valvular involvement, most commonly in the form of tricuspid regurgitation. Right ventricular (RV) dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2) is upregulated in many fibrotic disorders. Increased tumor expression of CCN2 has been shown in patients with small intestinal NETs associated with peritoneal fibrosis. At present, its role in carcinoid heart disease is unknown.

#78 The diagnostic and prognostic value of elevated proGRP levels in well- and moderately differentiated neuroendocrine tumors
Introduction: Chromogranin A (CgA) is the most frequently used marker in well- (grade 1) and moderately (grade 2) differentiated NETs. Although CgA is a more sensitive marker than the 5-HIAA, which was widely used until the last decade, CgA has some limitations. False-positively elevated CgA may occur in renal impairment, atrophic gastritis and during treatment of proton-pump inhibitors. Progastrin-releasing peptide (proGRP) was recently reported as a promising tumor marker for small cell lung cancer. Limited data suggests that ProGRP may be a potential tumor marker in NE tumors.

#106 Gastroenteropancreatic neuroendocrine tumors: single institution clinicopathological study
Introduction: Neuroendocrine cells are widely distributed throughout the body, and neoplasms from these dispersed cells can arise at many sites. They are distinguished into two broad categories: 1) Tumors identified as small cell lung carcinomas with biology and natural history of a high-grade malignancy and characteristics of small cell undifferentiated or anaplastic appearance by light microscopy. The WHO categorizes these tumors as poorly-differentiated neuroendocrine carcinomas; 2) Well-defined neuroendocrine tumors (NETs) with variable, but most lyindolent biologic behavior and characteristic well-differentiated histologic features. The majority arise in the gastrointestinal tract and collectively they are referred as gastroenteropancreatic neuroendocrine tumors (GEP/NETs). They include carcinoid tumors, pancreatic islet cell tumors (gastrinoma, insulinoma, glucagonoma, VIPoma, somatostatinoma), paragangliomas, pheochromocytomas, and medullary thyroid carcinomas. The WHO classifies the GEP/NETs as well-differentiated NETs (carcinoid tumors) if they are noninvasive and have benign behavior or uncertain malignant potential. In contrast, GEP/NETs with characteristics of low-grade malignancy with invasion of the muscularis propria or beyond, or metastases, are characterized as well-differentiated neuroendocrine carcinomas (malignant carcinoids). Pancreatic islet cell tumors, whether functioning or not, are classified as well-differentiated NETs or well-differentiated neuroendocrine carcinomas, due to the (depending on) histologic characteristics. The WHO classification for gastroenteropancreatic NETs based on stage (ie size and presence of metastases) and grade (mitotic rate, perineural and lymphovascular invasion, Ki-67 proliferative index) categorizes them as well-differentiated NETs, e.g., carcinoid tumors, or as well-differentiated neuroendocrine carcinomas.

#112 Chromogranin A is a sensitive marker for detection of recurrence in neuroendocrine tumors
Introduction: The chromogranin family is a family of large acidic proteins which are expressed in neuroendocrine cells. There are several members in this family (Chromogranin A, B (CgA and CgB) and the secretogranins). Here, we show that CgA is an excellent marker to detect recurrence in neuroendocrine tumors.
