Imaging Modality Depending on the Levels of Tumor Markers Abstract #2213

Introduction: 18 F-Fluorodihydroxyphenylalanine(18F)-FDOPA positron emission tomography (PET)/computed tomography (CT) has the advantage of being a noninvasive test and is by far the most promising imaging modality for neuroendocrine tumors (NETs).
Aim(s): The aim of this study is to present our experience between the correlation (18F)-FDOPA/PET-CT findings and elevated serum values of chromogranin A, serotonin and urinary excretion of 5-hydroxyindolacetic acid (5-HIAA) in patients with histologically verified (NETs).
Materials and methods: 29 patients (twenty gut, seven pancreas, one lung and one liver) were enrolled in our institution. Patients were separated in two groups according to those who had positive levels of tumors markers (15 patients) and those who had normal range levels of tumors markers (14 patients). All of them underwent PET-CT consisting of the injection of (18F)-FDOPA followed by 1 hour delayed PET of the whole body.

#16 Endoglin as indicator of metastatic neuroendocrine tumors of the pancreas
Introduction: Neuroendocrine tumors of the pancreas are rare, highly vascularized tumors. Endoglin, a Transforming Growth Factor-β co-receptor, is a marker for angiogenic endothelial cells. Angiogenesis is required for tumor progression and the development of metastases. Recently, endoglin expression was found to be a prognostic marker in pancreatic carcinomas. However, the role of endoglin in neuroendocrine pancreatic tumors has so far not been studied.

#18 Long-acting release octreotide induce complete response in type 1 gastric carcinoid tumors
Introduction: Gastric endocrine tumors (GET) are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, GET may also be aggressive when sporadic and may sometimes mimic the course of gastric adenocarcinoma. Current incidence of GETs is estimated at around 8% of digestive endocrine tumors. Yearly age-adjusted incidence is around 0.2 per population of 100,000. Gastric carcinoids (ECLomas) develop from gastric enterochromaffin-like cells (ECL cells) in response to chronically elevated gastrin. Type 1 tumors (ECLomas in the course of atrophic gastritis) may occur in conditions of achlorhydria secondary to auto-immune atrophic fundic gastritis. It occurs mostly in women and they are non-functioning tumors, typically found during upper GI endoscopy performed for dyspepsia. ECLomas present frequently as multiple polyps, usually < 1 cm in diameter in the gastric fundus. Type 1 tumors are almost exclusively benign lesions with little risk of deep invasion of the gastric parietal wall. The neoplastic ECL cells become progressively dedifferentiated with an increasing number of Ki-67 immunoreactive (IR) cell nuclei. In addition, there is a substantial decrease in argynophil and IR NE cells that can be visualized by conventional methods. ECLomas secondary to hypergastrinemia should be closely followed for signs of clinical and histopathological tumor progression. Such ECLomas deserve early, active, radical surgical treatment.
Traditionally, gastric carcinoid type 1 (GCA1s) are endoscopically or surgically removed, depending on the number, appearance and size of the tumors. Antrectomy, with surgical excision of the majority of the G cells, is thought to facilitate regression of these tumors by removing the source of excessive gastrin secretion; however, the long-term benefits of antrectomy still remain uncertain. Although proton pump inhibitors are effective in reducing hypergastrinemia-induced gastric acid hypersecretion in GCA2, they do not affect ECL-cell hyperplasia, and therefore their role in GCA1 is limited. Moreover, in selected cases, significant reduction of hypergastrinemia does not prevent development of ECL carcinoid, suggesting that, in addition to hypergastrinemia, other pathogenic or genetic factors may be involved. Treatment with somatostatin analogues (SSA) might impede ECL-cell hyperplasia by suppressing gastrin secretion and/or by a direct anti-proliferative effect on ECL cells. Treatment with SSAs in GCA1 leads to a substantial tumor load reduction, with a concomitant decrease of serum gastrin levels. Published data indicate an important anti-proliferative effect of SSA on ECL cells, providing clinical benefit and obviating, at least temporarily, the need for invasive therapies for GCA1. Morphometric studies demonstrated that, while antrectomy specifically decreased the volume of ECL cells versus the total volume of endocrine cells, octreotide reduces the overall endocrine cell volume. Although the number of treated patients is small, it has been suggested that SSA may exert important anti-proliferative effects either directly, by inhibiting ECL-cells proliferation, or indirectly through suppression of gastrin hypersecretion.

#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.

#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.
