Chromogranin A as a Predictor of Progression, Regression or Stable Disease in Ileo-Cecal Neuroendocrine Tumors Abstract #231

Introduction: Chromogranin A is an excellent marker for NET and tumor volume. Plasma CgA is suggested as the most reliable marker in follow-up of patients with some types of NET.
Aim(s): Changes in plasma CgA concentrations were compared to changes in CT according to the RECIST 1.1 criteria in a well-definded group of mid-gut NET.
Materials and methods: We investigated the diagnostic accuracy of plasma CgA as a predictor for progression, regression or stable disease compared to changes on CT scan using RECIST 1.1. in 84 patients with CgA positive midgut neuroendocrine tumors (NET), retrospectively, from file. CgA were measured with a radioimmunoassay specific for the hCgA(340-348) sequence.

#12 Chromogranin A as a predictor of progression, regression or stable disease in ileo-cecal (midgut) carcinoid tumors
Introduction: A general characteristic for NETs is their expression of certain proteins, such as chromogranin A (CgA), which is released from the dense core vesicles of NE cells, occasionally together with cell specific hormones, such as gastrin and serotonin. Plasma CgA seems to be closely related to tumor burden of intestinal carcinoid tumors in humans.

#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.

#28 Prognostic Clinicopathologic Factors in Longitudinally Followed Patients with Metastatic Small Bowel Carcinoid
Introduction: Neuroendocrine tumors demonstrate heterogeneous behavior based upon site of origin and specific histology. Even after controlling for anatomic location, disease stage and histologic grade, registry studies show persistent diversity of outcome in patients with midgut carcinoid.

#36 A monocentric analysis of patients with pulmonary neuroendocrine tumors over 15 years: long term survival and life quality dependent from histological subtypes and surgical management
Introduction: Pulmonary neuroendocrine tumors substantially differ from epithelial tumors in terms of tumor biology and prognosis. In specialized interdisciplinary centers, a broad therapeutical armentarium can be used to achieve optimal treatment.
