About

Conduct a prospective study to confirm the value of circulating tumor DNA and its aberrant methylation in longitudinal monitoring of surgical lung cancer patients.

Full description

Studies have already demonstrated the feasibility of circulating tumor DNA as a surrogate to reveal tumor mutation status in lung cancer patients and a few researches have shown the potential ability of using circulating tumor DNA in surveillance. However, no study focused on the value of methylation status of circulating tumor DNA in the surveillance and no strict prospective study has been performed in surgical lung cancer patients. The investigators plan to analyze the dynamic change of circulating tumor DNA and its methylation status longitudinally from preoperation to long term follow-up in surgical lung cancer patients, and compare assessment value between circulating tumor DNA detection with methylation , traditional imaging examinations and traditional blood tumor markers in the monitoring process.
