The UK’s devolved nations could detect greater numbers of lung cancer cases with improved screening programmes, new analyses by Cancer Research UK have found as the charity calls for governments to ’urgently implement’ such programmes.
Lung cancer is the leading cause of cancer death in England, Scotland, Wales and Northern Ireland and smokers and former smokers aged 55-74 are at greatest risk.
In November 2022, the National Screening Committee (NSC) recommended that everyone in this group be screened but, to date, only England has initiated a screening programme on this advice.
Almost 900,000 people were invited for checks during the pilot stages in England. Of the 200,000 scans carried out, more than 2,000 people were detected as having lung cancer, and 76% of those were identified at an earlier stage (stage 1 or 2) compared to 29% identified outside of the pilot programme in 2019.
Nationwide lung cancer screening could be a ‘game changer’
Cancer Research UK’s latest analyses suggests that equivalent lung cancer screening programmes in the devolved nations could diagnose around 4,000 more lung cancer patients in Scotland at an early stage over the next decade, as well as 2,400 more people in Wales and 1,400 in Northern Ireland.
If just 50% of eligible people took part in screening, earlier lung cancer diagnosis could save 2,300 lives in Scotland, 1,000 lives in Wales and 600 lives in Northern Ireland over the next 10 years, Cancer Research UK said.
Professor David Weller, professor of general practice at the University of Edinburgh, believes a nationwide screening programme ’has the potential to be a game changer when it comes to reducing the burden of lung cancer in Scotland’.
He said: ’For too long, lung cancer has been perceived as a disease you can’t do anything about, but we know that diagnosis at an early stage really can make a difference.
’Major trials of targeted lung cancer screening show significant reductions in mortality from lung cancer. Pilot studies in the UK and internationally consistently show people being diagnosed with lung cancer at an earlier stage.’
In Scotland, a pilot project called LUNGSCOT – of which Professor Weller is the principal investigator – is exploring the challenges for local lung cancer screening. It is running in Lothian with funding released for Grampian, Greater Glasgow and Clyde, and the Highlands and Islands.
A pilot is also running in Cwm Taf Morgannwg in Wales, where charities including Cancer Research UK are running a public petition in the hopes of raising the issue in the Senedd.
In Northern Ireland, there are no plans or pilots to report due to the lack of a Northern Irish Executive following the 2022 elections. That said, authors of the Northern Ireland Cancer Strategy 2022-2032 have said they intend to implement all NSC recommendations.
Debbie King, Cancer Research UK’s senior external affairs manager in the devolved nations, said: ’Lung screening matters because it means more people can be diagnosed at an earlier stage, when treatment is more likely to be successful.
’A fully-funded national targeted lung cancer screening programme in Northern Ireland, Scotland and Wales is a real chance to reduce the toll of this disease.
’There have been big improvements in how we diagnose and treat other forms of cancer, but long-term lung cancer survival in the UK isn’t much higher than it was 50 years ago. This is unacceptable when evidence shows that earlier diagnosis through targeted lung cancer screening can potentially help thousands of people live longer healthier lives.’
Cancer manifesto launched
These latest analyses were published shortly after Cancer Research UK released its manifesto for reducing cancer deaths by 20,000 a year by 2040.
While overall cancer deaths have halved over the last 50 years, progress is at risk of stalling in the UK, the charity said.
As part of the manifesto, Cancer Research UK has called on the next UK Government to address variation in treatment across different geographical areas, which includes optimising cancer screening programmes and accelerating the roll-out of the lung cancer screening programme in England.
On the manifesto, former national cancer director at the Department of Health and chair of the National Screening Committee, Professor Sir Mike Richards, said: ’Cancer outcomes in the UK are lagging behind comparable countries like Denmark. We need consistent funding and long-term strategies to make the UK the best in the world for cancer survival.’
