Blood Testing to Detect Cancer Recurrence in Patients With Early-Stage Non-Small Cell Lung Cancer

Sponsor: Fox Chase Cancer Center

Summary

This observational study will evaluate whether a blood test can detect the return of non-small cell lung cancer at least three months before it is identified on routine imaging. The test measures circulating tumor DNA (ctDNA), which consists of small pieces of DNA released by cancer cells into the blood. Detecting ctDNA after treatment may indicate that cancer cells remain in the body, even when cancer is not visible on scans. Approximately 200 adults with stage IB-IIIA non-small cell lung cancer who are considered candidates for surgery will participate at Fox Chase Cancer Center. Participants will receive standard-of-care treatment selected by their treating physicians, which may include chemotherapy and immunotherapy before or after surgery. Blood samples will be collected before treatment and at scheduled times during treatment and follow-up. Researchers will compare ctDNA results with routine imaging and clinical outcomes to assess how well the test predicts cancer recurrence. Participants will be followed for up to five years after surgery, with the primary analysis focused on the first three years. Additional research in a subset of participants will examine blood, tissue, and stool samples to explore relationships among immune responses, gut bacteria, treatment response, and cancer recurrence.
