NCT06523374
This study serves, in part, to prepare for a future large cohort study. The goal of the study is: 1. The collection of various tissue samples (blood, biopsies and "esophageal brushes") and their analysis. 2. To set up standardized methods for different genetic analyses (DNA-FISH and so-called single cell sequencing) on the esophageal tissue samples. 3. Evaluating the quality of life of Barrett's Esophagus patients and the degree of fear of getting cancer. Patients with a Barrett's Esophagus can participate in the study if they are minimally 18 years old, are capable of giving informed consent (fully understanding what the study entails before giving consent to participate), have Barrett Esophagus and are referred to one of the participating centers due to suspicion of high-grade dysplasia or early esophageal cancer, for which the participant will be evaluated by endoscopic imaging and biopsy. Study procedures: * An intake consultation will be planned, wherein the eligibility criteria will be assessed, and participant characteristics will be collected. * A routine gastroscopy will be planned twice during which several minimally-invasive interventions will be performed: drawing a blood sample, brush cytology during the endoscopy (a brush is used to obtain cells from the surface of the esophagus) and obtaining biopsy samples (small pieces of tissue). Each participant will need to undergo all the interventions. * Patients will have to complete questionnaires at three time points to assess their quality of life (EQ-5D-DL questionnaire) and fear of cancer recurrence (Cancer Worry Scale).
NCT07331857
Prospective, open-label, single-arm, early feasibility study (EFS) in 2 Patient cohorts: Cohort A - Dose finding / Dose response study in patients with various etiologies undergoing Esophagectomy and Cohort B - Patients with Barrett's Esophagus (BE) with Low-Grade Dysplasia (LDG) or High-Grade Dysplasia (HGD) without a visible (excisable) lesion. This is a pilot study which plan to enroll up to 5 eligible patients in the First Cohort (A) and up to 15 patients in the Second Cohort (B) of the study.
NCT03316053
The purpose of this study is to analyze biopsied tissue samples for changes in cells and genes involved in Barrett's Esophagus.
NCT02198976
The purpose of this study is to collect prospective observational data regarding endoscopic management and outcomes of patients with Barrett's oesophagus (BO) with high grade dysplasia and/or intramucosal carcinoma. To observe the natural history of patients with low grade dysplastic and non dysplastic Barrett's oesophagus
NCT00590239
* The use of high resolution endoscopy (HRE), narrow band imaging (NBI) and chromoendoscopy increases the detection rates of Barrett's esophagus (BE) and early neoplasia. * Endoscopic mucosal resection (EMR) will improve the accuracy for detection of dysplasia/early neoplasia. Specific Aim 1 - To create a video-atlas of non-dysplastic and dysplastic/early neoplastic lesions in patients with BE. This will be used for training purposes and to assess learning curve associated with these new technologies. Specific Aim 2 - To create a standardized classification system for the mucosal and vascular patterns observed in patients with BE. Specific Aim 3 - To determine the interobserver agreement using the video-atlas for the mucosal and vascular patterns classification agreed upon. Specific Aim 4 - To determine the endoscopic detection rate of esophageal cancer or precancerous lesions removed during endoscopy. Specific Aim 5 - To determine the pathologic and clinical outcomes of patients undergoing EMR/ablation; including morbidity, mortality and complications of the procedure. Results to date (June 2008) : this study is active and open to enrollment. Currently 26 patients have enrolled in this study at the Kansas City VA medical center. In order to participate, patients must be eligible for care at the KCVA hospital.
NCT05740189
Evaluate the efficacy and safety of the C2 CryoBalloon 180° Ablatie Systeem (CBAS180) at decremental doses for the treatment of dysplastic Barrett's epithelium.
NCT06381583
This study aims to develop a highly sensitive, specific, and cost-effective blood assay for the early detection of esophageal adenocarcinoma and its precursor lesions, using advanced machine learning and state-of-the-art biological analyses.
NCT02579460
The purpose of this study is to elucidate mechanisms whereby oxidative stress induced by acute reflux esophagitis: 1) activates p38 to regulate proteins that control the G1/S cell cycle checkpoint, and 2) activates HIFs (hypoxia inducible factors) to cause autocrine VEGF (vascular endothelial growth factor) signaling that triggers the EMT (epithelial-mesenchymal-transition) program in Barrett's esophagus.
NCT00574327
The purpose of this study is to determine or evaluate the risk factors such as smoking, family history etc. that cause esophageal cancer and to determine the genetic changes that lead to esophageal cancer. The investigators hypothesis is that systematic collection of data on the natural history of GERD and BE patients and risk factors for development of BE in patients with chronic GERD and progression of BE to dysplasia and adenocarcinoma will provide useful information to develop a decision model for risk stratification and risk reduction strategies in these patients. As of March 17, 2011, 585 patients have consented at the Kansas City VA Medical Center.
NCT05745857
Previous studies have confirmed the great potential of quantitative fluorescence molecular endoscopy (qFME) when looking at additional lesion detection initially missed by high-definition white light endoscopy (HD-WLE) for surveillance of Barrett's esophagus.
NCT01293448
The purpose of this study is to evaluate a cryoablation technique used to ablate human esophageal mucosa.
NCT01961778
Prospective randomized study comparing radiofrequency ablation and cryotherapy for the endoscopic treatment of Barrett's esophagus. The study is powered to assess clinical equivalence (non-inferior) of the treatment regimens.
NCT01733147

NCT01298999
The purpose of this study is to determine whether treatment with an experimental drug called YF476 in patients with Barrett's esophagus reduces the expression of tissue markers that are associated with an increased risk of developing esophageal cancer.
NCT01439594
The goal of this research is to conduct a pilot clinical study to evaluate the potential use of esophageal Optical Frequency Domain Imaging (OFDI) for assessing the success and degree of injury associated with therapeutic radiofrequency ablation techniques.
