Dynamic Changes of Circulating Tumor DNA in Surgical Lung Cancer Patients

Completed
Conditions
Non-small-cell Lung Cancer
Lung Neoplasms
Carcinoma
Registration Number
NCT02965391
Lead Sponsor
Peking University People's Hospital
Brief Summary

Previous study showed circulating tumor DNA levels reflect the total systemic tumor burden. Circulating tumor DNA levels should decrease after complete surgery and could be increase as tumor recurrence. Few study investigated the half time of circulating tumor DNA in lung cancer patients that no criterion has been established of how to use it for surveillance.

Detailed Description

For lung cancer patients who received surgery, multiple time of plasma will be collected before or after surgery. A series of mutations will be detected in plasma before surgery based on next generation sequencing. The positive mutation will be traced after surgery and in follow up.
