"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A study to see if referring more people to have a chest X-ray reduces the length of time it takes to diagnose lung cancer in people over 60 who are smokers (ELCID)
We know that this is an especially worrying time for people with cancer and their family and friends. We have separate information about coronavirus and cancer. Please read that information alongside this page. We will update that information as guidance changes.
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This study is looking at whether more people having urgent chest X-rays would affect the diagnosis of lung cancer in people over 60 who are at high risk of the disease due to smoking. This study is supported by Cancer Research UK as part of the National Awareness and Early Detection Initiative (NAEDI).
If you have symptoms that could be caused by lung cancer, your GP may arrange for you to have a chest X-ray. But because the symptoms could be caused by other less serious conditions, and may go away by themselves, the National Institute for Health and Care Excellence (NICE) has produced guidelines for GPs. The guidelines say that you should have an urgent chest X-ray if you’ve had certain symptoms for more than 3 weeks.
Researchers want to find out if people who are at higher risk of getting lung cancer should have an urgent chest X-ray even if they’ve had symptoms for less than 3 weeks.
This is a pilot study to see if it would be possible to run a larger trial looking at this.
The aims of the pilot study are to
- See if people are willing to take part in a trial looking at this
- Find out how many people go to their GP with symptoms they have had for less than 3 weeks
- See how many of those people are diagnosed with lung cancer
Who can enter
You cannot volunteer to take part in this study. If you are over 60 and are a smoker (or have been), your GP may ask you to take part if you’ve gone to see your doctor and have at least 1 of the following
- A new or different cough
- Increased breathlessness or wheezing
You cannot enter this study if you
This pilot study aims to recruit 386 people who go to their GP with symptoms that could be due to lung cancer.
The study is randomised. The people who agree to take part will be put into 1 of 2 groups at random. Neither you nor your doctor can decide which group you are in.
People in one group have tests according to the NICE guidelines, which means that you won’t have a chest X-ray unless you’ve had certain symptoms for more than 3 weeks.
People in the other group have an urgent chest X-ray, regardless of how long they’ve had symptoms.
The researchers will ask everybody taking part to fill out some questionnaires. This should take less than 15 minutes.
The researchers will send you more questionnaires 2 months later. You can fill these out at home and return them in a prepaid envelope.
Agreeing to take part in the study means you are giving the researchers permission to look at your medical notes to see if you need to have any treatment during the next year.
The study team will ask some people to take part in an interview. They will ask them about their experience of taking part in the study. You don’t have to have an interview if you don’t want to, you can still take part in the study.
If you have an urgent chest X-ray, this may be an extra hospital visit. But you would have had an X-ray anyway if your symptoms didn’t go away.
Depending on which group you are in, you may have an X-ray that you don’t need. This means you would be exposed to some unnecessary radiation. But the level of radiation in a chest X-ray is extremely low.
