Description of intervention(s) / exposure
To evaluate whether risk prediction model(s) can identify people at high risk of lung cancer who do not meet current screening eligibility criteria, to undertake lung cancer screening.
• An adapted aPLCOall2014 model for light / never smokers (Tammemägi MC, Church TR, Hocking WG, Silvestri GA, Kvale PA, Riley TL, et al. (2014) Evaluation of the Lung Cancer Risks at Which to Screen Ever- and Never-Smokers: Screening Rules Applied to the PLCO and NLST Cohorts. PLoS Med 11(12): e1001764 https://doi.org/10.1371/journal.pmed.1001764) which incorporates known risk predictors for never smokers developing lung cancer (age, family history of lung cancer, personal history of cancer, secondhand smoke, indoor / outdoor air pollution, exposures to environmental or occupational lung carcinogens and inflammatory pulmonary diseases).
• Individuals with predicted lung cancer/6-year risk of >0.0151 risk threshold, are deemed eligible and offered a low dose CT scan to screen for lung cancer.
Eligible participants will attend a radiology service for the low dose CT scan. The participant will be instructed to lie on an x-ray table with their arms above their head and to hold their their breath for 5 - 10 seconds while the table moves through the CT scanner. The procedure will take less than 10 minutes.
A radiographer who is suitably qualified in CT scanning protocols, will administer the CT scan and a specialist radiologist will assess the films and complete a synoptic report. The scan results will be provided to the participant and their primary care provider for appropriate management.
If a nodule is detected on the CT, a followup scan will be offered dependent on the risk of developing lung cancer e.g. 12 months for low risk, and 3 months for moderate risk. If the participant is assessed as high risk of developing lung cancer, they will be referred to a lung specialist for further investigations.
For enrolled participants who are not eligible for CT screening they will be offered to participate in annual online questionnaires about their health status including current comorbidities, new health conditions, medications, quality of life and bone health. There may be more than one online questionnaire and each may take 10-15 minutes to complete.

• Any medical condition, such as severe heart disease (e.g. unstable angina, chronic congestive heart failure), acute or chronic respiratory failure, home oxygen therapy, bleeding disorder, that in the opinion of the investigator could jeopardise the subject’s safety during participation in the study or unlikely to benefit from screening due to shortened life-expectancy from the co-morbidities

• Have had other non-curatively treated cancer outside the lung in the last 5 years.
• Pregnancy
• Pneumonia or bronchitis requiring antibiotic treatment within the last 12 weeks

Summary
Brief summary
Current guidelines suggest invitation of smokers (current or past) of 20 pack years or more (US Preventative Services Task Force) to participate in lung cancer screening. However, a significant proportion of lung cancers will not be detected by these criteria. Therefore, the aim of this study is to determine the feasibility and lung cancer detection rate of identifying and screening at-risk never/light smokers for lung cancer using personalised risk prediction.

Who is it for?
People aged from 55 to 74 years (inclusive), and have never smoked or are a current/former light smoker.

Study details
Interested participants will be assessed for screening eligibility by completing a questionnaire which incorporates known risk predictors for never smokers developing lung cancer (age, family history of lung cancer, personal history of cancer, secondhand smoke, indoor / outdoor air pollution, exposures to environmental or occupational lung carcinogens and inflammatory pulmonary diseases).
Participants will also be invited to participate in an optional sub-study of blood, breath and body fluid and remnant tissue collection to research novel biopmarkers of lung cancer risk.
Participants determined to have a 6-year lung cancer risk more than 1.51%,will proceed to single low-dose spiral chest computerised tomography (LDCT) scan. The LCDT scan will be examined for any lung nodules, and referral for follow-up treatment provided accordingly.
Participants will also complete a number of Quality of Life and health status questionnaires annually for 10 years post-enrollment.. Participants found ineligible for LDCT will be enrolled into the health questionnaire component of the study for 10 years to determine whether they develop lung cancer during the study period.

It is hoped that this study may show new ways to identify people who may benefit from lung cancer screening. with low dose CT scans..
