This is a multi-centre, observational basic science study to follow patient who have undergone radical treatment, surgery or radiotherapy for Non-small Cell Lung Cancer (NSCLC) between two and five years previously. Following consent, participants will be asked to provide blood samples every six months for up to the next five years. Information from their routine clinical care, including information from any imaging, diagnostic tissue samples and blood tests will be collected. We will also request access to any original surplus diagnostic material, as well as future, excess tissue from diagnostic samples.
Blood samples will be analysed using various new scientific techniques looking to correlate emergence of new primary cancer (or recurrence of original NSCLC) with blood based markers.
