Plain English Summary

Background and study aims
This study is a randomised controlled trial to test novel invitation methods and materials designed to increase informed uptake of lung cancer screening in individuals at high risk of lung cancer. Lung cancer Low (radiation) Dose Computed Tomography (LDCT) screening has been shown to reduce the number of people who die of lung cancer and of all causes by picking lung cancer up at an earlier stage when treatment is more successful. Screening is now underway in various countries across the world. For the benefits of lung screening to clearly outweigh the harms, screening needs to be targeted at people who are at high risk. However multiple studies have shown that uptake is particularly poor in this group. Qualitative research in this area has highlighted some of the possible explanations for this. This has enabled the development of a novel method of approaching this target population. The aim of this study is is to compare lung screening uptake in people who are sent our new materials designed to improve uptake with people receiving more conventional materials.

Who can participate?
Adults aged 60 to 75 who are current smokers

What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive a lung health check invitation and those in the second group receive the standard care. Participants are followed up to see if participants attended the health check two weeks after receiving the invitation,.

What are the possible benefits and risks of participating?
Not provided at time of registration

Where is the study run from?
University College London (UK)

When is the study starting and how long is it expected to run for?
October 2014 to December 2019

Who is funding the study?

Scientific title

Randomised controlled trial to test novel invitation methods and materials targeted to increase informed uptake of lung cancer screening in individuals at high risk of lung cancer


Study hypothesis

The aim of this study is to investigate the impact of a novel invitation strategy on attendance rates to a pre-lung cancer screening lung health check appointment.

Topic: Cancer; Subtopic: Lung Cancer; Disease: Lung (small cell)


Patients are individually randomised (1:1) to receive either control invitation materials or intervention invitation materials. Those who attend will undergo a "lung health check" and be invited to a baseline screening scan if eligibility criteria are fulfilled.

Control invitation materials: These are similar to standard materials used in other NHS screening programmes.

Targeted invitation materials: The intervention invitation materials are specifically designed and hypothesised to improve uptake to a pre-screening lung health check appointment.

Follow Up Length: 12 month(s)

Intervention type



Drug names

Primary outcome measure

Attendance to lung health check measured approximately 2 weeks post receipt of invitation.

Secondary outcome measures

1. Adverse eventsare monitored throughout the study in all participants
2. Demographics of attenders and non-attendersis determined at the initial primary care search
3. Eligibility, uptake and willingness for baseline screening scan measured at baseline (lung health check appointment)
4. Informed decision making measured at baseline lung health check appointment, the day after and 3 months after the appointment
5. Investigations and costs generated from screening determined at the end of study
6. Mortality and Survival rates determined at the end of study
7. Psychological burden of screening determined at baseline lung health check appointment, the day after and 3 months after the appointment
8. Radiological and clinical outcomes determined at the end of study
9. Smoking data, lung cancer risk and medical history determined at baseline (lung health check appointment)

Target number of participants

Planned Sample Size: 2000; UK Sample Size: 2000; Description: A total of 2000 patients will be invited for a lung cancer screening appointment, 1000 in each arm. This will provide 90% power to detect a significant difference in uptake of 35% vs. 42%, with 5% significance level and two-sided testing. We estimate 35% uptake in the control group with a 7% increase in uptake in the intervention group based on similar studies examining the effect on screening uptake of ‘psycho-educational’ materials.

Total final enrolment


Participant exclusion criteria

1. Active diagnosis of lung cancer or metastases
2. CT thorax within the past year
3. Inability to consent to study
4. Palliative care register
5. GP's alert to co-morbidity that contraindicates screening or treatment for lung cancer
