Lung cancer screening - gaining consensus on next steps - proceedings of a closed workshop in the UK.

Lung cancer is the most common cause of cancer death in the UK, and survival from the disease is persistently poor. Efforts to improve outcomes for patients have focused on ways of reducing late diagnosis of the disease, and access to optimal treatment. Research on lung cancer screening has so far provided some evidence of an impact on lung cancer mortality, but there is some debate about whether implementation of a national screening programme should await further trial data, principally that from the NELSON trial. The ongoing poor outcomes and the belief amongst some clinicians that there is sufficient evidence has prompted several local projects testing out lung screening in their communities, sometimes referred to as lung health checks or proactive approaches to high-risk individuals. Funding from NHS England has been forthcoming to support this. Acknowledging roll-out of such activities, which effectively constitute local lung screening in the absence of a NSC recommendation, it was timely to bring key national stakeholders together with academic and clinical experts, to agree a way forward. Cancer Research UK therefore convened a closed workshop in March 2018, involving national and international expertise. This paper outlines the proceedings, key discussion points, highlighted research gaps, and areas of consensus and next steps.
