Neuroendocrine tumor disease state and RAND-36 health-related quality of life scores Abstract #45

Introduction: Health-related quality of life (HRQL) can be disrupted in patients with malignancies.
Aim(s): To compare the HRQL burden of patients with neuroendocrine tumors (NET) in different disease states relative to the general population.
Materials and methods: Patients with NET were invited via e-mail to participate in an online anonymous survey. The survey consisted of demographic and disease-related questions and two standardized measures of HRQL (RAND-36 and PROMIS-29). HRQL scores for the US general population are normalized to 50. RAND-36 scores were compared using analysis of variance among three groups: patients with no tumor currently present (e.g., was surgically removed)—no current NET; patients with tumor that has not been surgically removed or has come back after surgery—current NET, but without carcinoid syndrome; current NET with carcinoid syndrome. Score differences of 2.5 - 5.0 points are generally regarded as clinically meaningful. Lower scores indicate worse HRQL.

#9 Case Management of Metastatic carcinoid of the Foregut,Midgut and Hindgut:the relevance of Ki-67 prognostication
Introduction: The predictive value of tumor grade in the prognosis of carcinoid is insufficient and somehow misleading. The grade and differentiation in carcinoid tumors must be seen in conjunction with the Ki-67 index. The Ki-67 protein is a cellular marker for proliferation, present during all active phases of the cell cycle (G1, S, G2 and mitosis) and absent from resting cells (G0). It is therefore an excellent marker to determine the growth fraction of a given cell population. The Ki-67 labelling index is often correlated with the clinical course of carcinoid.

#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.

#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.

#14 Radioguided surgery in NET: First impression with Ga-68 labeled somatostatin analogues
Introduction: Neuroendocrine tumors (NET) constitute a heterogenous group of neoplasms. The development of Gallium-68-labeled somatostatin analogues, such as DOTA-NOC or DOTA-TOC, PET/CT have dramatically improved the diagnosis of neuroendocrine tumors. Surgery remains the treatment of choice for localized disease as well as metastatic disease. The aims of surgery are: improvement of symptoms, reduction of tumor mass / burden and to give better quality of life to patients. Recurrent laparotomies often lead to multiple adhesions and altered anatomy. So it is increasingly difficult for imaging physicians and surgeons to separate non-malignant from malignant tissue.

#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.
