Filter by:Neuro-endocrine tumours (NET) are the most frequent tumours of the small intestine. In spite of their small size, these tumours have the particularity of forming mesenteric metastasis and ganglionic secondary lesions along the superior mesenteric axis, which is in close proximity to the superior mesenteric artery (SMA). Surgery is the only curative treatment. The complete resection being a factor for good patient prognosis, risks of subsequent local complications (occlusion, bleeding) must be discussed. The limiting factor for resectability is arterial vascular invasion considering the risk of postoperative small bowel syndrome. At the moment, the choice of imaging examination and its protocol is not standardized, nor the description of the tumoral mesenteric and ganglionic extension, especially the criteria defining a lymph node as lymphadenopathy. In addition, the complexity of SMA's anatomy and the absence of criteria for arterial invasion defining arterial invasion may lead to a misinterpretation of the preoperative imaging , and thus to an incomplete planning of the surgical procedure. To correct this absence of radiological standardization, the investigating team has developed a reading grid for Computed Tomography (CT) aimed to facilitate preoperative planning of small bowel NET. The main objective of the current study is to improve the semiotic description of the mesenteric and ganglionic tumoral extension of small intestine NET using a technically optimized imaging examination and a standardized reading grid in order to plan the best surgical procedure which would allow maintaining a minimal length of small intestine needed to yield a satisfying quality of life and nutritional status. The secondary objective of this study is to evaluate the reproducibility of the standardized scanner's reading grid.
To study the sensitivity and specificity of NGS in detecting Microsatellite State in blood and to evaluate its potential application in gastrointestinal cancer.
This phase II trial studies how well abemaciclib works in treating patients with digestive system neuroendocrine tumors that have spread to other places in the body, do not respond to treatment, and cannot be removed by surgery. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Neuroendocrine tumours (NETs) are rare and include a heterogeneous group of neoplasms derived from the endocrine system found in the gastrointestinal tract, pancreas and lung. Gastroenteropancreatic (GEP) NETs represent the majority of neuroendocrine neoplasms (NEN) and the annual incidence of all GEP-NETs has been estimated to 6.98 per 100,000 person-years in 2012 and is steadily rising. While data on the incidence of metastatic GEP-NET is limited, more than 50% of patients with GEP-NET have metastatic disease at the time of diagnosis. Incorrect and delayed diagnoses are still common. Treatment options include surgery, locoregional interventions, and systemic treatment. The Lyon Real world Evidence in Metastatic NeuroEndocrine Tumours study (LyREMeNET) is a descriptive observational cohort study. The main objective is to assess the healthcare resources use and the corresponding costs for management of patients with metastatic GEP and lung NETs. The secondary objective is to describe the clinical characteristics, prognostic factors, treatment patterns, and the overall survival among patients with metastatic GEP and lung NETs.
Gastroentero-pancreatic neuroendocrine tumors (GEP-NETs) are a heterogenous group of neoplasms that arise from enterochromaffin cells of the gastrointestinal (GI) tract and pancreas. They account for 50-70% of all incident NETs. Due to the lack of symptoms in the early stage of disease and the frequency of nonspecific GI symptoms, GEP-NETs are difficult to diagnose. Identification of effective biomarkers (such as Chromogranin A) to improve GEP-NET diagnosis, as well as to assess treatment efficacy, relapse and prognosis, is important for improving outcomes for patients with GEP-NETs. The purpose of this study is to validate the performance of Brahms (BRAHMS) Chromogranin A II Kryptor (KRYPTOR) assay to monitor the course of disease in patients with well-defined GEP-NETs.
Observational, Multicenter, Post-market, Minimal risk, Prospective data collection of PillCam SB3 videos (including PillCam reports) and raw data files and optional collection of Eneteroscopy reports
Purpose: To compare the accuracies of computed tomographic (CT) enterography and magnetic resonance (MR) enterography for the detection and radiomics characterization of small-bowel tumors (including gastrointestinal stromal tumors, adenomas and lymphomas, etc); Hypothesis: MR enterography was noninferior to CT enterography for the diagnosis and evaluation of small bowel tumors in generally well-distended small bowel.
Small intestine carcinoid tumors are rare. Small intestine Familial Carcinoid Tumors (FCT) are defined by the occurrence of at least 2 cases of this tumor type in first- or second-degree relatives. The estimated prevalence of FCT is 2.6%-3.7% in patients with small intestine carcinoid tumors. Because of its rarity, epidemiologic, clinic and pathologic features of FCT have been scarcely described. Molecular abnormalities associated with FCT have been poorly explored. Constitutional genetic factors predisposing to FCT have not been discovered to date. Only one abnormality (mutation of the IPMK gene) has been reported in one FCT family only, but not found in other series. The main objective of this study is to identify the constitutional factors predisposing to small-intestine FCT (and other midgut localizations: ascending colon and appendix). The secondary objectives are to describe the clinic and pathologic features associated with FCT.
The concept of natural orifice transluminal endoscopic surgery (NOTES) (1) has evolved to endoscopic full thickness resection (EFTR). It represents innovation in technique that allows endoscopists to advance further into the endoscopic surgical space. EFTR has transformed the ability to tackle subepithelial tumors (SETs) and early mucosal neoplasm that are not amenable to classic ESD technique, enhance the staging accuracies for marginal lesions, and even increase the diagnostic capabilities for infiltrative disorders. Thus far, multiple methods have been described to perform EFTR, including nonexposed and exposed techniques, with the closure occuring before resection or after resection, respectively (2). Early comparative studies show no difference between the two methods (3). However, the procedures themselves are limited by the current tools available and by described techniques to achieve resection. Investigators are described here a novel non-exposed technique, with closure before resection, using the Endomina device.
