Toward a Preoperative Classification of Mesenteric Lymph Node Metastases for Better Selection of Carcinoid Tumors Before Radical Surgery Abstract #973

Introduction: Surgery for small bowel carcinoid (SBC) and lymph node (LN) metastases, when technically possible, represents the best therapy. However, surgical challenge is (i) not to recuse patients for false unresectable mesenteric artery invasion, and/or (ii) to avoid extensive small bowel resection.
Aim(s): We hypothesized that the length of bowel resection would not reflect the quality of lymphadenectomy. Then, we proposed a 4-stage preoperative CT-scan (or MRI) classification that could predict complete resecability of SBC and LN.
Materials and methods: Consecutive patients operated on a 3-year period were retrospectively analysed. The liaison between number of resected LN and resection length of SB were performed in highly selected patients who fulfilled inclusion criteria by an ANOVA. Preoperative imaging was reviewed blindly by two independent observers and data correlated to intraoperative findings by weighted Kappa coefficent.

#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.

#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.

#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.

#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment
Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.
