About this study

Upper digestive tract cancer (UDC) is a major disease burden worldwide encompassing all cancers involving the digestive tract (from oral cavity to duodenum). A majority of patients presenting with this disease are diagnosed late and have poor overall survival rates (\<20%). NICE referral guidelines for diagnostic endoscopy are usually associated with late disease. Exhaled breath testing is a non-invasive and acceptable technology utilising mass spectrometry (MS) which has shown promise at diagnosing cancer at an early stage. Previous research has shown that products formed as a result of metabolism can be measured in breath and saliva (biomarkers). This has the ability to accurately identify patients with upper gastrointestinal (UGI) cancers from breath. Our initial pilot data has demonstrated that changes in the breakdown of metabolites release volatile organic compounds (VOC) which can be measured with MS. This data is supported by other patient studies. However no previous study has been performed utilising a non-invasive technique with breath and saliva. Thus the aim of this study is to identify VOCs present in patients with this disease. In this multi-centre study the investigators want to overcome the limitations of previous work by utilising non-invasive samples (breath, saliva and urine) in patients in multiple sites. The investigators aim to conduct a study in patients with UDC and those without. The investigators hope that the results of this study will provide ev…
