Official title
GALACTIC 1 - Glasgow Low-dose CT and AI-based Diagnostics to Case Find Lung Cancer and Other Cardio-respiratory Long-term Conditions - Feasibility Study
Overview
Lung cancer is one of the most common and serious cancers in Scotland and is often diagnosed at a late stage. Early detection is crucial to improving survival rates. The value of screening for lung cancer with low-dose CT (LDCT) scans has been established, and these scans can also identify other diagnoses earlier. Additional tests undertaken alongside the CT scan may add value to the lung cancer screening program being rolled out. This study aims to explore the feasibility and utility of a lung cancer screening program with added heart and breathing tests within a single clinic visit. A Lung Health Check will be offered to people at higher risk of lung cancer, specifically those aged 55-74 with a history of cigarette smoking. This will include a quick and painless LDCT scan, which uses a small amount of radiation to create detailed images of the lungs to detect lung cancer at an early and more treatable stage. In this "GALACTIC-1" study, the investigators will explore whether structured reporting of the CT scan, combined with additional tests (blood sample, ECG heart trace, and spirometry breathing test), can help identify conditions such as chronic obstructive pulmonary disease (COPD), lung scarring (pulmonary fibrosis), coronary artery disease, heart failure, and early signs of bone fractures (osteoporosis). This enhanced Lung Health Check may improve overall health by identifying and allowing early management of these conditions. The investigators plan to use the data from the "GALACTIC-1" study to explore AI performance by comparing it to reporting done by doctors. The results will help shape future rollout of lung cancer screening across Scotland, ensuring it is effective, efficient, and beneficial. The investigators will also have a focus group with patients and interviews with NHS staff to understand their opinions on the screening.
