Validation of the SPOT-MAS Lung Test Using Circulating Tumor DNA for the Detection of Lung Cancer

Prior treatment

• Subject has a health problem that substantially limits life expectancy and/or the ability or willingness to have curative lung surgery.
• History of any malignancy (subjects who have undergone surgical removal of skin squamous cell cancer may be enrolled provided the procedure was completed at least 12 months prior to the date of provision of informed consent for the study).
• Currently taking any anti-neoplastic or disease-modifying anti-rheumatic drugs.
• Currently receiving treatment for pneumonia.
• Any major physical trauma (e.g., disruption of tissue, surgery, organ transplant, blood product transfusion) within the 30 days leading up to the provision of informed consent.
• Participation in a clinical research study in which an experimental medication and/or medical procedure has been administered or may be administered within the 30 days leading up to providing informed consent or may be administered through the time of subject screening.

Other illness

• Subject is undergoing CECT for investigation of highly suspicious symptoms for lung cancer.
• Pre-existing or history of lung cancer.
• Known medical condition which, in the opinion of the investigator, should preclude enrollment into the study.
