ROCS (Radiotherapy After Oesophageal Cancer Stenting) Study
Study Details
Study Description
Brief Summary
The single most distressing symptom for more than 70% of patients with oesophageal cancer is difficulty in swallowing (dysphagia) caused by blockage of the gullet by a tumour. This causes severe restrictions on food intake, physical activity, social functioning and overall quality of life. Amongst the more effective treatments for improving swallowing, is the insertion of a metal stent across the blocked part, which then self-expands to open up the gullet (Self Expanding Metal Stent or SEMS). The addition of radiotherapy may help to improve the problems caused by dysphagia and provide an additional survival benefit.
The purpose of this study is to test the impact of adding radiotherapy to SEMS on:
-
the length of time swallow remains improved for
-
quality of life
-
survival

Detailed Description
The primary objective of the study is to assess the impact of radiotherapy in addition to self-expanding metal stent (SEMS) placement on time to progression of patient-reported dysphagia in a patient population unable to undergo surgery.
Patients will be eligible to take part in the trial if they have oesophageal cancer, are in need of SEMS because of dysphagia, are aged 16 years or older, have been clinically assessed to be able to receive radiotherapy, have an expected survival of at least 12 weeks and are able to give written informed consent.
496 patients will be randomised to receive either SEMS alone or SEMS with radiotherapy. The radiotherapy will be given as an outpatient either as five treatments (one per day) over one week, or ten treatments over two weeks. Questionnaires will be completed before treatment, and at weeks two and four and then monthly for up to one year to assess quality of life and cost effectiveness. Interviews will be held with trial participants at three time points to explore their experiences while on the trial. Interviews will also be held with patients who do not consent to take part in the trial to explore their reasons for non-consent.
Treatments:
Arm A: Self-expanding metal stents (SEMS) (Control Arm) SEMS insertion will be undertaken in accordance with standard local protocols. Covered or partially covered metal stents will be used and the length type and mode of stent placement will be selected by the clinician. Insertion will occur within two weeks of randomisation.
Arm B: SEMS plus external beam radiotherapy (Intervention Arm) External beam radiotherapy (EBRT) is routinely available at regional cancer centres across the UK. For palliation of dysphagia in oesophageal cancer, a radiotherapy course delivering a tumour absorbed dose of 20Gy in 5 fractions or 30Gy in 10 fractions within 4 weeks of SEMS insertion.
There will also be a qualitative component of the trial will have two aims: i) to explore the feasibility of patients' recruitment to the trial and ii) to explore participants' experience of the trial interventions. It will examine their experience of consent and recruitment including reasons for declining, and examine patients' motivation to accept randomisation to an intervention which may include extra radiotherapy. This is an optional component and will require separate consent. Patients who do not consent to the trial, but who do consent to the qualitative component, will be interviewed about their reasons for not-consenting as soon as possible after the approach to participate.
Trial participants who consent to the qualitative component will be interviewed three times:
at weeks one and four to capture initial decision-making thoughts and then after the interventions (week 8) to explore patients' experience of interventions and perceptions of benefit or detriment.
