Project Name
ELCID (Improved Lung Cancer Identification by targeted chest x-ray)



Principal Investigator
Professor Richard Neal, North Wales Centre for Primary Care Research

Type of study

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). 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:

  1. See if people are willing to take part in a trial looking at this
  2. Find out how many people go to their GP with symptoms they have had for less than 3 weeks
  3. See how many of those people are diagnosed with lung cancer
