Filter by:Barrett's oesophagus is a condition where the lining of the oesophagus (gullet) wall changes. People with Barrett's oesophagus are at risk of developing oesophageal cancer but can have regular checkups to detect changes before they progress to cancer. Every two years patients with Barrett's are offered examination by passing a fibreoptic tube into the oesophagus (gastroscopy) to remove small tissue samples (biopsies), which are examined in the laboratory to check for changes. Bowel cancer is the third most common cancer in the UK, and the second leading cause of cancer deaths. Prevention and early detection are the most effective strategies of dealing with bowel cancer. Most cancers develop from benign polyps (growths) in the bowel. Polyps are common and have the potential of developing into cancer over the course of many years. Patients with a prior diagnosis of Barrett's oesophagus and colonic polyps undergo regular endoscopic examinations known as surveillance endoscopies. This is done to detect changes in the cells of Barrett's oesophagus or further polyps. Current practice is to capture recorded videos of Barrett's surveillance examinations and still images of polyps prior to their removal. Endoscope technology continues to advance. These newly developed technologies are marketed to have claims of superiority in performance over preceding generations often without the back up of scientific data but at a significant financial cost. The aim of this study is to use endoscopic images and videos recorded as part of routine clinical practice to compare the current version of Olympus endoscopes with the new version launched by the company.
This study aims to elucidate the relationship between the microbiome, inflammation, and the microenvironment in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC), with the end goal of developing a non-endoscopic testing strategy based on pathogenic factors to identify patients at highest risk for EAC. To accomplish this the investigators will enroll 100 patients with known BE (50 with dysplasia or EAC) and 50 subjects without BE undergoing upper endoscopy. Prior to endoscopy each subject will undergo three minimally invasive potential screening and surveillance tests: saliva (oral microbiome), breath test (exhaled volatile organic compounds), and tethered capsule sponge sampling (methylated DNA markers). The study will evaluate these novel tests in combination with clinical and anthropometric factors to describe an optimal strategy for BE screening and monitoring.
This is a multi-center, prospective, randomized study which will enroll patients undergoing endoscopic surveillance due to a history of histologically confirmed dysplasia. A member of the research team will approach a potential subject to discuss participation in the study, including background of the proposed study, inclusion and exclusion criteria, benefits and risks of the procedures and follow-up. If this is of interest to the subject, the informed consent form is discussed and presented. The subject must sign the consent form prior to enrollment. This form will have prior approval of the study site's Institutional Review Board (IRB). Failure to obtain informed consent renders the subject ineligible for the study.
Patients will be recruited from participating institutions prior to planned routine care EGD with WATS3D brush samples and forceps biopsies. Eligibility will be reviewed and patients who are potentially eligible for the study will be approached regarding the study. If interested, participants will be consented and proceed with routine care EGD. The study coordinator or other research personnel will document information from the routine care endoscopy as part of this research study. Follow-up information collected will include WATS3D cytology and forceps biopsy pathology results from any routine care endoscopy performed during the course of participation in the study, any surgeries received and related to their condition, and any other care received as part of their condition. WATS3D samples will be sent to CDx Diagnostics for analysis.
To assess diagnostic accuracy and clinical effectiveness including cost-effectiveness analysis of pCLE in patients after finishing the endoscopic treatment of BORN in detecting persistent/recurrent IM, recurrent neoplasia and buried glands.
This pilot clinical trial studies how well a swallowable sponge cell sampling device and next generation sequencing work in detecting esophageal cancer in patients with low or high grade dysplasia, Barrett esophagus, or gastroesophageal reflux disease. Checking biomarkers in abnormal esophageal cells using a swallowable sponge cell sampling device and next generation sequencing may improve diagnosis and treatment of esophageal cancer.
Barrett`s esophagus (BE) is the major esophageal pre-neoplastic lesion in which dysplastic transformations eventually can lead to cancer development. Today, the only way for early detection of pre-neoplastic lesions is an endoscopic surveillance programme with tissue sampling for histopathology, the latter being the only validated biomarker for esophageal adenocarcinoma (EAC)-risk available. New biomarkers are warranted for better patient selection before inclusion into BE surveillance programmes. Epidemiologic studies have demonstrated suppressed numbers of cancer prevalence in cohorts being under different medical treatment. In a British epidemiological study 2007 Sjöberg et al noted a lower prevalence of EAC among patients treated with antihypertensive drugs interfering with the renin-angiotensin system (RAS) such as AT1R-blockers and ACE-inhibitors. The last decade this endocrine signalling system has been proven to be involved in pathological conditions such as inflammation, wound-healing and even cancer, in several organ systems. Earlier reports from the investigators laboratory indicate the existence of a local RAS in the esophageal wall musculature and in the squamous mucosa. In the investigators latest explorative study, the investigators discovered the altered expression of "classical" RAS components in BE with and without dysplasia (unpublished results). By a possible alteration in RAS-related protein-expression in BE with increasing grade of dysplasia towards EAC, the investigator may have a possible "pathway" leading to biomarkers for cancer-development. Furthermore, the already well-known anti-hypertensive drugs ACE-inhibitors and AT1R-blockers may interfere with the risk of malignancy in BE. The investigators therefore wish to test, in an exploratory prospective randomized placebo-controlled setting, whether RAS-related protein-expressions in BE are altered by the addition of RAS-suppressant pharmaceuticals. In the same manner the investigators wish to see if the expressions of well-known biomarkers for cancer and inflammation are altered.
The purpose of this study is to further validate the use of probe-based confocal laser endomicroscopy (pCLE) for the evaluation of Barrett's Esophagus and associated neoplasia in a larger patient base.
A pilot study to assess the accuracy and acceptability of a magnet assisted capsule endoscopy in detecting esophageal pathology compared to standard endoscopy.
This pilot clinical trial studies how well tethered capsule endoscope works in screening patients with Barrett esophagus (BE), a condition where the lining of the esophagus has changed or has been replaced with abnormal cells that may lead to cancer also called esophageal cancer. In an attempt to prevent the progression from BE to esophageal cancer, patients undergo a standard procedure called esophagogastroduodenoscopy (EGD) where patients are sedated and the doctor uses an endoscope to examine the tissue in the esophagus. Tethered capsule endoscope is a tiny capsule with a laser scan inside and a very thin cord attached to it. Patients swallow the capsule and the thin cord keeps the capsule in specific area in the esophagus. After pictures of the lining of esophagus are taken, the capsule is removed using the thin cord. Tethered capsule endoscope may be able to identify tissue changes in patients with BE without the need for sedation or anesthesia, thus eliminating the associated risks and costs associated with EGD.
