Largest ever UK lung cancer screening study underway

Largest ever UK lung cancer screening study underway

University College London Hospital (UCLH) and University College London (UCL) have announced their ‘SUMMIT Study’ which aims to:

  • detect lung cancer early amongst at-risk Londoners, when the chance of successful treatment and survival is greatest
  • support development of a new blood test for early detection of multiple cancer types, including lung cancer

The study will also provide evidence to inform a potential future national lung cancer screening programme. It aims to recruit approximately 50,000 people aged 50-77 from north and east London to give a blood sample. Half of the participants will be people at high risk of lung and other cancers due to a significant smoking history and the other half will be people who are not at high risk for cancer.

Delivered by UCLH in close collaboration with UCL and GRAIL, Inc. (a US healthcare company focused on the early detection of cancer), the study is a key programme of UCLH Cancer Collaborative, which brings together healthcare organisations across north and east London, to improve early cancer diagnosis, outcomes and care.
