Ki-67 to Predict Recurrence and Survival of Pancreatic Neuroendocrine Tumors Abstract #2276

Introduction: Despite evidence of different malignant potential, postoperative follow-up is similar for G1 and G2 pancreatic neuroendocrine tumors (panNET) and adjuvant treatment is currently not indicated.
Aim(s): This study investigates the role of Ki67 with regard to recurrence and survival after curative resection of panNET.
Materials and methods: Retrospectively, patients with resected non-functioning panNET diagnosed between 1992 – 2016 from 3 institutions were analyzed. Included were patients with G1 or G2 tumors, without distant metastases or hereditary syndromes. Patients were re-categorized into Ki67 0-5% and Ki67 6-20%. Cox regression analysis with Log Rank testing was performed for recurrence and survival.

#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.

#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.

#30 Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia
Introduction: Normal adult lungs contain scattered pulmonary neuroendocrine cells (PNEC). Reactive PNEC hyperplasia is commonly observed in persons who live at high altitude, in cigarette smokers, and in numerous lung diseases. Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia (DIPNECH) is a rare entity in which PNEC hyperplasia appears without predisposing conditions. According to the 1999 WHO lung tumor classification, DIPNECH is thought to be primarily a neuroendocrine proliferative process, which can be associated with carcinoid tumors and with a clinical picture of constrictive obliterative bronchiolitis. To date, available data regarding the treatment and the prognosis of this rare condition is limited.
