Description of intervention(s) / exposure
This is an exploratory study to evaluate potential proteomic markers in salivary samples. This is novel and is seeking to determine if a panel of salivary biomarkers could assist in the diagnosis of Barrett's oesophagus and its pathological variants, dysplasia and oesophageal adenocarcinoma. Samples (saliva, blood, gastric secretions) will be collected at standard-care encounters. Samples will be collected by a trained research nurse. At each standard-care encounter participants will be asked to contribute blood samples (20-40mls), saliva samples and gastric fluid from your usual endoscopy procedure.
A 'healthy' control group (a) will be compared to other risk-stratified sub-groups of Barrett's neoplasia.
(b) Non-dysplastic Barrett's Oesophagus (BO) group (n=50) – patients with current Barrett's Oesophagus (BO) but without evidence or history of Barrett’s-dysplasia, undergoing endoscopy
(c) Dysplastic BO group (n=50) – patients with current BO and either low-grade or high-grade dysplasia, undergoing endoscopy
(d) Early Oesophageal Adenocarcinoma (OAC) group (n=50) – patients with current BO and evidence of early OAC, undergoing endoscopy
(e) Advanced OAC group (n=50) – patients with current BO and advanced OAC, undergoing either endoscopy, surgery, or non-operative treatment for this

Outcomes
Primary outcome [1] 337799 0
Identify biomarkers (such as proteins, cells, DNA/RNA/miRNA and microorganisms) that correlate with disease stage. This is an exploratory outcome. The proteins analysed in the laboratory from the collected participant samples will assist in identifying which proteins are relevant for different disease stages of the same condition.
Timepoint [1] 337799 0
Samples are collected at baseline before undergoing an endoscopic procedure.

Timepoint [2] 337800 0
Samples will be evaluated at Griffith University research lab. They will be transported on the day after they are collected from participants. The lab will undergo testing of samples within 3 weeks. Time to analysis of samples are not relevant for this outcome measure.

Samples will be evaluated at Griffith University research lab. They will be transported on the day after they are collected from participants. The lab will undergo testing of samples within 3 weeks. Time to analysis of samples are not relevant for this outcome measure.
Secondary outcome [3] 434802 0
Establish a protocol to isolate and amplify nucleic acids (DNA/RNA) as a biomarker.
Timepoint [3] 434802 0
The protocol will be established at the completion of the study. This is unknown exactly but anticipate approximately 5 years to collect this data to determine this outcome measure.

Summary
Brief summary
This study aims to determine if a panel of salivary biomarkers could assist in the diagnosis of Barrett's oesophagus and its pathological variants, dysplasia and oesophageal adenocarcinoma.

You may be eligible for this study if you are an adult male or female referred for investigation of reflux symptoms or other suspected gastrointestinal disease, as well as patients with established Barrett’s oesophagus and/or suspected or established oesophageal adenocarcinoma.

Any patient with one of the Barrett's related conditions or random healthy patients who may undergo an endoscopy for another indication, maybe approached to consider participation in this study. Participants will be asked to contribute samples of saliva, blood and gastric fluid before undergoing an endoscopic procedure.

Participants will be asked to contribute samples of saliva, blood and gastric fluid before undergoing their usual endoscopic procedure. It is hoped that findings from this study will help to develop a simple non-invasive saliva test to screen for oesophageal cancer.
