Early Cancer Detection Test - Lung Cancer Scotland

Detection in Blood of Autoantibodies to Tumour Antigens as a Case-finding Method in Lung Cancer Using the EarlyCDT-Lung Test

HYPOTHESIS In a high risk population the EarlyCDT-Lung test reduces the incidence of late stage tumours;3 / 4 / Unclassified (U) at diagnosis compared to normal clinical practice.

AIMS To assess the effectiveness of EarlyCDT-Lung test in increasing early stage lung cancer detection, thereby reducing the rate of late stage (3 / 4 / U) presentation, compared to normal clinical practice; to assess the cost-effectiveness of EarlyCDT-Lung test compared to normal clinical practice; to assess the effectiveness of EarlyCDT-Lung test in reducing adverse outcomes including potential psychological and behavioural consequences.
