Brief summary
Tumor genomic clonal evolution assessed with liquid biopsy of stage IB,II and IIIA non-small cell lung cancer patients after getting radical resection. Plasma circulating tumor DNA (ctDNA) analysis detects molecule residual disease and predicts recurrence in patients. The concordance of the relative abundance of mutations in plasma ctDNA with cancer recurrence.
Detailed description
In the study, 200 of stage IB,II and IIIA non-small cell lung cancer patients obtained radical resection will be recruited. All the patients will receive biopsy genotype assay and ctDNA liquid biopsy. The abundance of mutations of ctDNA was tracked at 4 time points, including: 1. st: 10 Days after patients received radical resection. 2. nd: When patients finished the chemotherapy or target drug delivery two cycles. 3. rd: 10 Days after patients finished the chemotherapy or target drug delivery four cycles. 4. th: When tumor recrudescence / 2 years after radical resection. Tumor genomic clonal evolution was assessed by analyzing the relative abundance of mutations in plasma circulating tumor DNA (ctDNA).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Tumor genomic clonal evolution assessed with liquid biopsy of stage IB,II and IIIA non-small cell lung cancer patients after getting radical resection. | From assignment of the first subject to the time point when tumor recrudescence or 2 years after radical resection. The last participant will be recruited before June 30,2021. | The tumor molecular clones and the frequency of gene mutations from 1021 tumor related genes will be detected by next-generation sequencing, which will be matched with the CT scanning. |
| The concordance of the plasma ctDNA detection status with Progress Free Survival (PFS) and Overall Survival (OS) after radical resection or/and under adjuvant therapy. | From assignment of the first subject to the time point when tumor recrudescence or 2 years after radical resection. The last participant will be recruited before June 30, 2021. | Plasma circulating tumor DNA (ctDNA) analysis detects molecule residual disease and predicts recurrence in patients. All the patients will receive biopsy genotype assay and ctDNA liquid biopsy. |
