Brief Summary

Nearly 10,000 people die each year in the United Kingdom from cancer of the lower gullet and stomach, known as known as oesophago- gastric adenocarcinoma (OGC). OGC is detected late as symptoms are non- specific and often mistaken for common problems such as heartburn. This translates to fewer than 2 in every 10 patients diagnosed with OGC living longer than 5 years. The breath of people with OGC is enriched with volatile chemicals (VOCs) that indicate cancer. When measured in a breath test, it detects OAC 80 out of 100 times. Whilst encouraging, there is scope to improve the detection rate by giving patients a stimulant drink that amplifies the production of tumour specific VOCs only, to increase their detection in the breath test. The goal of this observational study is to produce an enhanced second-generation breath test with superior ability to detect OGC through augmentation of breath. This will improve long term survival from cancer using an entirely non- invasive test. All participants (cancer and control participants) will consume an oral stimulant drink (OSD) and provide breath samples pre and post consumption of the drink at set time points (maximum 2 hours after consumption of the drink). The investigators will compare the breath VOCs from both groups, before and after consumption of the OSD to see if the OSD has a desired augmentation effect and can improve the accuracy of the OGC breath test. With this second-generation breath test, participants with vague symptoms can undergo a quick, non- invasive test, have samples analysed in a safe and accurate manner and be subsequently stratified based on their risk of having OGC, leading to earlier disease detection and improved clinical outcomes.

Outcome Measures

Primary Outcomes (2)

  • To establish a second- generation augmented breath test with improved diagnostic accuracy for the detection of OG adenocarcinoma.

    This breath test will utilise serial breath sampling following the ingestion of an augmentation solution (OSD). Breath samples will be taken pre and post consumption of the OSD and fold changes in the VOCs will be calculated. The entire process of breath sampling is non- invasive.

    12 months

  • To determine the diagnostic accuracy of the augmented exhaled breath test, in the prediction of oesophago-gastric cancer (OGC).

    The investigators will generate an untargeted VOC breath model following exhaled VOC augmentation.

    12 months

Secondary Outcomes (2)

  • To comprehensively characterise the tissue lipid input and lipidomic reprogramming in oesophagaeal and gastric adenocarcinoma in comparison to healthy non- cancer tissues.

    deadline December 2022

  • To identify the mechanistic pathways and origins of the production of breath Volatile compounds by investigating the tumour lipidome.

    12 months

Study Arms (2)

Oesophago- gastric adenocarcinoma patients

EXPERIMENTAL

Oesophagogastric adenocarcinoma (OG) cancer patients (who are neoadjuvant chemotherapy treatment naïve) will receive 120mls of a sterile oral stimulant drink (OSD) (manufactured by Ingenza ltd), which is an ISO accredited laboratory. The active component of the drink is iron sulphate (5g/l), pH 5-6. Breath will be taken following an optimised methodology designed by the VOC laboratory at Imperial college London at baseline and then at 30, 60 and 90 minutes following consumption of the drink. Participants will be nil by mouth for 6 hours prior to the breath test, they can have water up to 2 hours before the breath test.

Dietary Supplement: Oral Stimulant Drink

Benign healthy control patients

ACTIVE COMPARATOR

Age, gender and demographic matched patients who have had a negative oesophagogastroscopy within 1 year which is negative for adenocarcinoma will be recuited into the comparison arm. Patients will be given the same OSD and breath will be sampled at the same time points as the experimental arm.

Dietary Supplement: Oral Stimulant Drink
