      P1.20-004 - UK lung Cancer Screening trial (UKLS): Base line data (ID 1796)

      09:30 - 16:30  |  Author(s): J.K. Field

      • Abstract

      Background
      Lung Cancer causes over 35,000 UK deaths per year: early detection by CT screening has been shown to reduce mortality in the USA by 20%.

      Methods
      UKLS is a pilot randomised controlled trial, screening individuals at a high risk of developing lung cancer (>5% over 5yrs) with low-dose CT. UKLS is population-based, approaching people of 50-75yrs identified through local primary care records and using a validated lung cancer risk prediction model to identify high risk individuals from the target group (Raji Annals of Int. Med 2012). We report observations made from the initial recruitment to the trial. 250,000 individuals were approached in Liverpool and Cambridgeshire, 30% responded positively to the first questionnaire. 4000 individuals were recruited and randomised to receive either a low-dose CT scan or usual care. All CTs were double read according to UKLS protocol. Nodules were reported as category 1, 2, 3 or 4 depending on size and volume (Baldwin et al. Thorax 2011). Participants with category 4 nodules (>500mm3) were referred to the lung cancer multi-disciplinary team (MDT) for further workup. Individuals with a category 3 nodule (50-500 mm3) underwent a repeat CT within 3 months, whereas category 2 nodules (15-50mm3) were followed up at 12 months. The trial is currently in follow-up and some participants are still in the 3 and 12 month phases.

      Results
      1991 high risk UKLS participants underwent baseline CT by June 2013. 1044/1991(52.4%) individuals had nodules requiring further imaging or work-up. 79/1991 (4.0%) had nodules which required referral to the MDT clinics at the pilot sites for further workup. At this time 31/1991(1.6%) had a prevalent lung cancer. 27/31 lung cancers (87.1%) were non-small cell lung cancer and 25/31 lung cancers (80.6%) were Stage I or II (based on pathological staging or clinical staging where the pathology staging was not available).

      Conclusion
      UKLS has already demonstrated 1.6% prevalence, utilising the LLP risk prediction model to identify high risk individuals, which compares favourably with the NELSON and other European trials. The Pilot UKLS is due to provide an interim report in 2014.
