Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The Cytosponge-trefoil factor 3 (TFF-3) is a pill on a string combined to a molecular biomarker which could help early diagnosis of gastric cancer and GIM. Cytosponge-TFF3 has been showed in previous research to be useful to diagnose Barrett's oesophagus, a condition of the food pipe similar to GIM.
The aim of this study is to investigate the utility of the Cytosponge in combination with molecular biomakers to diagnose GIM

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In parallel to this clinical study, a experimental study will be carried out aimed at evaluating the utility of molecular biomarkers to refine/improve the diagnostic accuracy of the Cytosponge test. The hypothesis is that the non-invasive Cytosponge, in combination with molecular biomarkers, can accurately detect GIM to the same extent as conventional, but more invasive, endoscopic procedures.
Patients will be invited to participate in the study if they are due their surveillance endoscopy, because they have the disease of interest (GIM or GC; cases) or have been referred for an upper endoscopy for abdominal complaint (controls). On the day of the endoscopy the patient will swallow the Cytosponge under supervision of a trained research nurse prior to the endoscopic procedure. The participant will also provide information on demographics, clinical exposures (alcohol, tobacco, drugs), have measurements of weight and height taken and they will also complete a validated gastrointestinal symptoms questionnaire. A blood sample will be taken from the cannula used for the sedatives or through venepuncture. The patients will then undergo their planned endoscopy with additional sampling of gastric juice (suctioned through the endoscope) and some additional research biopsies in addition to a standardized clinical protocol to diagnose GIM. The above research procedures will be performed prior and during the endoscopy. No further research procedures will follow afterwards beyond the day of the endoscopy.
The aim is to develop a non-invasive test which can be used to screen patients at risk for GIM to allow early detection and treatment of pre-cancerous gastric lesions and ultimately reduce the number of patients dying of gastric cancer.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cases
This will include patients with:
* existing diagnosis of proximal GIM undergoing endoscopic surveillance
* a new diagnosis of proximal GIM requiring repeat endoscopy
* a historical diagnosis of GIM retrieved from the pathology records through retrospective analysis and lost in follow up
* gastric adenocarcinoma from upper GI multidisciplinary meeting.
Cytosponge-TFF3
Cytosponge is a less invasive procedure than endoscopy and consists of an expandable, spherical mesh, which is attached to a string and contained within a soluble capsule. Five minutes after swallowing (once the capsule has dissolved), the spherical mesh, which measures around 3cm in diameter can be retrieved by pulling on the string. Upon retrieval the Cytosponge scrapes against the surface of the top of the stomach and oesophagus and collect epithelial cells. The Cytosponge sample is then placed into a preservative fluid and the specimen is processed for molecular tests. Trefoil Factor 3 (TFF3) is a protein that is expressed in intestinal type epithelia of the gastrointestinal tract. TFF3 is the best biomarker, which can be coupled to the Cytosponge to diagnose intestinal metaplasia.
Controls
Controls will be patients with no known premalignant conditions of the upper GI tract and fit to undergo an upper endoscopy. They will be recruited via standard referral routes for upper GI endoscopy due to upper GI symptoms via standard referral routes. Individuals must be able to provide informed consent.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Any participant 18 years and above clinically fit for an endoscopy with upper GI symptoms leading to referral for endoscopy (controls)
* Ability to provide informed consent
Exclusion Criteria
* Patients with previous diagnosis of Barrett's oesophagus oesophageal varices, stricture or requiring dilatation of the oesophagus.
* Patients unable to stop anticoagulation therapy/medication timely before the procedure (heparin or tinzaparin, apixaban, rivaroxaban, dabigatran, edoxaban; 48 hours, warfarin; 5 days, clopidogrel; 7 days)
* Individuals who have had a myocardial infarction or any cardiac event less than six months ago.
* Individuals who have had a cerebrovascular event \< 6 months ago where their swallowing has been affected
* Patients who have had previous treatments such as Photodynamic therapy (PDT), Radiofrequency ablation or Argon Plasma Coagulation for dysplastic Barrett's oesophagus
* Participants who are unable to provide informed consent.
* Participants under age 18.
NB - Endoscopy is generally avoided in pregnant women and therefore it is unlikely that any pregnant women will be included although pregnancy would not be an absolute contraindication. Pregnancy/ pregnancy test will not be recorded as part of the trial.
