Description of intervention(s) / exposure
The GATOR study aims to determine characteristics and clinical outcomes of patients with
newly diagnosed gastro-oesophageal cancer in routine clinical practice, and the clinical decision making process involved with treatment selection and timing over a period of 10 years. Patient demographics, clinical and pathological disease factors and treatments will be captured by accessing patient medical records. Clinical details will be captured every 3 - 6 months from diagnosis until the patient's death, with no additional testing required by patients.

Statistical methods / analysis
Descriptive statistics will be utilized when comparing clinical characteristics between groups. Chi-square and Fisher’s test will be used to test associations. The Kaplan-Meier method will be used for survival analyses. The stratified log rank test will be used to compare survival curves between different subgroups of participants, and p-values of 0.05 will be considered significant. Regression analysis may also be used in univariate and multivariate analysis for relevant associations. Identifiable data will not be used during analysis.

Summary
Brief summary
The purpose of this study is to create a database of early and late stage gastro-oesophageal cancer patients.

Who is it for?
You may be eligible for this study if you are aged 18 or over, have gastro-oesophageal cancer and are a patient at one of the participating sites.

Study details
All enrolled patients will contribute data to the development of the web database. Data captured will include presentation and disease characteristics, patient characteristics, surgical and/or drug treatments administered, survival and treatment outcomes. Data will be collected for up to 10 years and will be updated regularly by study personnel throughout the patient’s treatment and follow-up from their medical record.

It is hoped this research will contribute important information about all patients with gastro-oesophageal cancer and help to inform future treatment decision-making for clinicians.
