Plain English summary of protocol
Background and study aims
Non-small cell lung cancer (NSCLC) is the UK’s leading cause of cancer deaths. Early diagnosis of lung cancer is key to improving survival rates. Most patients aren’t diagnosed until stage 4, when a cure is often not possible. Sierra Medical are developing a new and unique non-invasive screening test to detect NSCLC from a simple cheek swab with extremely high accuracy. To get the technology approved for use in hospitals, they need to conduct a series of clinical trials. This is the first clinical trial required to gain approval.
Who can participate?
1. Non-smokers with no history of lung disease
2. Current or ex-smokers with no history of lung disease
3. Current or ex-smokers with confirmed COPD
4. Current or ex-smokers with lung cancer (NSCLC only)
5. Smokers and non-smokers with other types of lung cancer
All aged 18 years and over
What does the study involve?
Participants will be seen in a research clinic where medical history will be obtained, lung function tests are performed and two cheek swabs are taken. These swabs will be analysed to demonstrate that there is a difference between cells from patients with and without lung cancer.
What are the possible benefits and risks of participating?
There will be no immediate benefit to the participant. However, if the study is successful participants will contribute to developing a lung cancer screening test that will enable earlier detection of lung cancer which will provide better outcomes to future lung cancer patients. The participant will be paid £10 to cover time and travel. There are very few risks associated with participation in the study, however, the participant may experience temporary irritation to the inside of their cheek where they were swabbed and/or temporary dizziness from forced exhalation during the lung function test (spirometry). Both side effects are rare and temporary.
Where is the study run from?
Queen Alexander Hospital (UK)

| Scientific title | Infrared analysis of buccal cell swabs as a novel non-invasive screening test for lung cancer in individuals exposed to carcinogens |
| Study acronym | RADiCAL |
| Study objectives | Infrared (IR) fingerprints collected using lab-based IR micro-spectroscopy of individual human buccal mucosa cells can be used to differentiate between smokers with non-small cell lung cancer (NSCLC) and smokers/non-smokers without NSCLC with sufficient accuracy to be used as an initial screening test for lung cancer. |
| Ethics approval(s) | Approved 20/03/2019, South Central - Berkshire Research Ethics Committee (Bristol REC Centre, Whitefriars, Level 3, Block B Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)20 7104 8057; berkshire.rec@hra.nhs.uk), ref: 19/SC/0100 |
| Health condition(s) or problem(s) studied | Chronic obstructive pulmonary disease (COPD) and/or non-small cell lung cancer |
| Intervention | Patients will attend one study visit where the following will be obtained/performed: 1. Informed consent 2. Specific medical history 3. Brief medical history 4. Smoking history 5. Assessment of food and other potential contaminates 6. Collection of cheek swabs 7. Lung function test (spirometry) 8. Confirm eligibility 9. Record adverse events 10. Acceptability questionnaire |
