Health-Related Quality of Life Determinants in Swedish Patients after Surgery for Small Intestinal Neuroendocrine Tumors Abstract #2025

Introduction: Overall survival for patients with small intestinal neuroendocrine tumors (siNETs) is often long even with metastatic disease, making quality of life issues especially relevant. The impact of surgery on their quality of life is unknown.
Aim(s): We investigated determinants of health-related quality of life (QoL) in patients who underwent surgery for a siNET.
Materials and methods: Patients operated for a siNET between 1st July 1998 and 31st October 2016 at Skåne University Hospital who were alive in February 2017 were sent EORTC QLQ-C30 and EORTC QLQ-GINET21 questionnaires, after approval by the research ethics committee in Lund. Global QoL, physical function, disease-related worries, diarrhea and endocrine symptoms were evaluated with multiple regression in relation to patient-, tumor- and treatment-related factors. STATA 11® was used for statistical analysis.

#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.

#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.

#33 Survival of Neuroendocrine Tumour Patients in Newcastle NHS Foundation Trust
Introduction: Neuroendocrine tumors (NETs) are rare neoplasms, with an incidence of 2-2.4 per 100,000, which derive from the neurones and epithelial cells of the diffuse neuroendocrine system. Neuropeptide-secreting NETs may present with overt clinical symptoms including abdominal pain, flushing and diarrhoea, whereas non-functioning NETs may be asymptomatic or present with obstructive symptoms. In Newcastle NHS Foundation Trust, NET patients are managed with a multi-disciplinary approach, according to UK and European NET guidelines.

#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.
