Brief Summary
This is a feasibility study testing the use of the Cytosponge™ device in patients with known oesophageal cancer treated with pre-operative or definitive chemoradiation. All participants will receive one Cytosponge™ procedure at one time-point within 4-16 weeks after completion of chemoradiotherapy.

Outcome Measures
Primary Outcomes (1)
Completion Rate
The percentage of consented, evaluable patients successfully undergoing the Cytosponge™ procedure.
Day 1 following intervention
Secondary Outcomes (4)
Safety; Number of SAEs Related to the Device Procedure
Two week follow up
Number of Participants With Positive Cytosponge™ Results From Biomarker Analysis (i.e. Presence of Cytological Atypia and/or p53 Abnormality)
From sample taken from Cytosponge™ on day of intervention
Acceptance Rate
Day 1 after questionnaire completion
Number of Patients Who Would be Prepared to Repeat the Procedure
Day 1 after questionnaire completion
Study Arms (1)
Cytosponge™
EXPERIMENTALAll participants will receive the Cytosponge™ device.
Interventions
Cytosponge™ is a capsule-sized device which contains an expandable, spherical mesh which is attached to a string. The capsule dissolves in the stomach after swallowing, releasing the sponge which is then retrieved by gently pulling the string after five minutes. As the sponge is pulled out it collects the cells from the lining of the gullet.
Eligibility Criteria
You may qualify if:
- Male or female, Age \>/=16 years who
- have undergone pre-operative CRT as treatment for oesophageal cancer and due to undergo oesophagectomy or
- have undergone definitive CRT as treatment for oesophageal cancer
- weeks post completion of CRT
- Dysphagia score 0-2 (Mellow Scale)\*
- Able to swallow tablets
- Physiologically fit for endoscopy
- Written (signed and dated) informed consent
- The patient is willing and able to comply with the protocol for the duration of the study, and scheduled follow-up visits and examinations.
You may not qualify if:
- Known to have oesophageal varices or stricture requiring dilatation of the oesophagus.
- Unable to temporarily discontinue anticoagulation therapy/medication prior to their procedure\*
- Oesophageal stent
- Other psychological, social or medical condition, physical examination finding or a laboratory abnormality that the Investigator considers would make the patient a poor study candidate or could interfere with protocol compliance or the interpretation of study results.
- Patients on anti-coagulation therapy are eligible for the study as long as they are considered suitable candidates for endoscopic biopsy (follow local hospital procedures for management of patients on anticoagulation due to undergo endoscopy). If temporary discontinuation of anticoagulation is required, this should be after consultation with the patients clinical care team.
