Background and study aims
Lung cancer is the leading cause of cancer death worldwide and accounts for approximately 28% of all cancer deaths worldwide. Despite advances in medical diagnostics and treatment, the outlook for lung cancer has not improved considerably during the last few decades. New developments in CT scanning have led to a renewed interest in lung cancer screening. Although studies have shown that screening reduces the number of lung cancer deaths, the cost-effectiveness, the best screening policy, and the balance between harms and benefits are still unknown. The aims of this study are: to investigate whether screening in a high-risk population leads to a reduction in lung cancer deaths of at least 25%; to estimate the impact of lung cancer screening on health-related quality of life and smoking cessation; and to estimate the cost-effectiveness of lung cancer screening for subgroups.

Who can participate?
People aged between 50 and 75 who were current smokers or former smokers who had quit smoking less than 10 years ago.

What does the study involve?
Participants are randomly allocated to either the screening or the control group. Screening group participants receive CT screening for lung cancer over several years, whereas participants in the control group receive no screening (usual care).

What are the possible benefits and risks of participating?
It is a feature of screening programmes that relatively few of the people who are invited for screening benefit from it, while a relatively large number of them will be exposed to minor unfavourable effects. In considering whether screening is justified, it is important to ensure that the favourable effects of screening (fewer deaths) should reasonably balance out the harms caused by screening (overdiagnosis, overtreatment, false-positive screening result, anxiety, discomfort etc). This will be investigated by this study.

Where is the study run from?
Department of Public Health, Erasmus MC, Rotterdam, The Netherlands. Participating centres: University Medical Centre Groningen, University Medical Centre Utrecht, Kennemer Gasthuis Haarlem (the Netherlands), and University Hospital Leuven (Belgium).

When is the study starting and how long is it expected to run for?
August 2003 to December 2015

Who is funding the study?
The Netherlands Organisation of Health Research and Development (ZonMw), the Dutch Cancer Society (KWF), and the Health Insurance Innovation Foundation (Innovatiefonds Zorgverzekeraars), Siemens Germany, Roche Diagnostics, G. Ph. Verhagen Stichting, Rotterdam Oncologic Thoracic Study (ROTS) group, Erasmus Trust Fund, Stichting tegen Kanker, Vlaamse Liga tegen Kanker, and LOGO Leuven.

Primary study designInterventional
Study designMulticentre randomised active-controlled parallel-group trial
Secondary study designRandomised parallel trial
Study type Participant information sheet
Scientific titleDutch Belgian randomised lung cancer screening trial (NELSON)
Study acronymNELSON
Study objectives1. To establish in a randomised controlled trial if screening for lung cancer by multi-slice low-dose computed tomography (CT) in high risk subjects will lead to a 25% decrease in lung cancer mortality
2. To estimate the impact of lung cancer screening on health-related quality of life and smoking cessation
3. To estimate cost-effectiveness and help policy making
Ethics approval(s)The Minister of Health approved the NELSON trial after a positive advice of the Dutch Health Council (22/11/2000), because of the Population Screening Act. Furthermore, the Medical Ethical committees of the participating centers (University Medical Centre Groningen, University Medical Centre Utrecht, Kennemer Gasthuis Haarlem [the Netherlands], and University Hospital Leuven [Belgium]) also gave their approval.
