Filter by:The purpose of this study is to evaluate the safety and effectiveness of the CryoSpray Ablation System to treat esophageal low grade dysplasia (LGD) or high grade dysplasia (HGD) within Barrett's Esophagus (BE).
This is a study of Barrett's Esophagus (BE) and Gastroesophageal Reflux Disease (GERD). It aims to look at the long term efficacy of evidence-based cutting edge diagnostic and therapeutic algorithms and techniques such as radiofrequency ablation, endoscopic mucosal resection and surveillance endoscopy with biopsy. Additionally, biological analyses will be performed in hopes of identifying biomarkers associated with the progression of BE to esophageal cancer.
The purpose of this study is to determine if confocal laser endomicroscopy (CLE) can improve detection of Barrett's esophagus, dysplasia, and early esophageal cancer.
The purpose of the study is to compare the treatment of esomeprazole 40 mg once daily and lansoprazole 30 mg once daily in controlling intragastric pH in Barrett's Esophagus patients
The overall objectives of this BETRNet Research Center (RC) are: 1. to conduct a rigorous, integrated spectrum of transdisciplinary human research in Barrett's esophagus (BE) and esophageal adenocarcinoma (ECA) 2. to increase the biological understanding of key observations made by our clinical researchers; 3. to translate knowledge derived from genetic, epigenetic, and transcriptome research to solving clinical dilemmas in detection, prognosis, prevention, and therapy of BE in order to prevent EAC and improve the outcomes of EAC; 4. to foster a transdisciplinary and translation research culture and to effectively expand and enhance scientific research focused on BE and EAC; 5. to evaluate research and transdisciplinary programs and to continuously improve research, productivity and enhance translational implementation. These objectives build and synergize on existing multi-institutional collaborative networks and the considerable clinical, basic science, and translational expertise available at our institutions, focusing on improving the outcomes of patients with BE and EAC. The overarching organization framework for this RC proposal is 1) to focus laboratory research on understanding the genetic susceptibility, genomic and epigenetic changes that influence the development of BE and EAC; and 2) to then translate laboratorydiscoveries into clinical applications for effective detection, molecular risk stratification, and prevention of progression from BE to EAC.
In a related study, the investigators have found evidence that patients with Barrett's esophagus have a leak for oral sucrose to leave their upper gastrointestinal tract, enter the blood, and be filtered into urine. The amount of sucrose appearing in an overnight urine sample can be used to indicate the presence of Barrett's esophagus and/or esophagitis in a patient reporting with reflux (GERD) symptoms. The leak is presumably in the Barrett's epithelium itself. This phenomenon will be used to test if a standard 8 week therapy of Nexium in a first-time-presenting GERD patient can reduce the leak as a means of assessing the efficacy of the drug in that patient. The investigators predict that Nexium will reduce leak in esophagitis but not Barrett's patients.
Background: The incidence rate for esophageal adenocarcinoma (EAC) has risen 10% per year over the past two decades and is the most rapidly increasing cancer in the U.S. Barrett's esophagus (BE), a metaplastic change from the normal squamous esophageal epithelium to a specialized intestinal-type columnar mucosa, increases the risk of EAC by 30-125, and is considered a precursor lesion for EAC. Individuals diagnosed with BE are currently entered into endoscopic surveillance programs to look for dysplasia or EAC. However, only 5% of subjects diagnosed with EAC have a previous diagnosis of BE or have been part of a surveillance program, so alternative screening methods are needed. Objectives: The primary goal of this project is to identify a practical blood-based biomarker(s) that can be used as a screening test to determine who has BE and who does not. Secondary goals of the project are to characterize germ-line and tissue biomarkers associated with BE, and to compare biomarkers in non-BE patients with and without GERD. Tertiary goals are to explore associations between biomarkers in blood or tissue and progression from BE to dysplasia or EAC, and to assess the stability of proteomic patterns over time. Eligibility: This study will be conducted among patients in the Barrett's Esophagus Registry (currently with 206 registrants) established at the National Naval Medical Center (NNMC) in Bethesda beginning in 1992, as well as a comparison group of approximately 600 matched non-BE patients endoscoped in the GI clinic at NNMC for other conditions. Design: Blood and tissue samples will be collected as well as questionnaire data on risk factors and medications as well as GERD. Data analyses will be based primarily on laboratory testing of newly collected esophageal biopsies, brush samples, and blood samples, but secondarily will also include use of archival tissue biopsy samples. Follow up of BE Registry patients will include standard periodic surveillance endoscopies, additional blood samples, and ascertainment of disease status (i.e., progression). To distinguish BE versus non BE-patients in this case-control study, we will: assess predictability of BE status from serum proteomic patterns; characterize esophageal biopsies and brush samples for selected DNA alterations, RNA expression, and proteomic profiles; genotype patients for selected polymorphisms potentially associated with BE; compare blood and tissue biomarkers in non-BE patients with and without GERD; explore the association of biomarkers with progression from BE to dysplasia or EAC; assess proteomic pattern stability over time in BE patients.
This research study is trying to determine whether Barrett's esophagus and associated esophageal cancers, specifically esophageal adenocarcinoma are inherited in certain families. Persons who are affected with Barrett's esophagus or esophageal cancer (adenocarcinoma type) are asked to complete a questionnaire that determines their habits and asks a detailed family history. Family members of patients seen at University Hospitals of Cleveland are also being recruited for screening tests of their esophagus. The investigators plan to eventually screen family members at all participating institutions. This research will eventually lead to the identification of inherited genetic changes that cause Barrett's esophagus and esophageal cancer. It will help the investigators develop better methods for preventing or identifying esophageal cancer at an early curable stage.
