stage III locally advanced unresectable non-small-cell lung cancer, circulating tumor DNA, peripheral blood mononuclear cells
Brief summary
This study aims to dynamically monitor the expression profile status of peripheral blood mononuclear cells (PBMC) and the changes in circulating tumor DNA (ctDNA) levels in patients with stage III locally advanced unresectable non-small-cell lung cancer(NSCLC) after concurrent chemoradiotherapy or sequential chemoradiotherapy, and to explore biomarkers related to the immune microenvironment and the optimal time point for immunotherapy after chemoradiotherapy.
Interventions

For women of non-surgical sterilization or reproductive age, use of a medically approved contraceptive method (such as an intrauterine device, birth control pills, or condoms) during the study treatment period and within 3 months after the study treatment period; Women of reproductive age who are not surgically sterilized must be negative for serum or urine HCG within 7 days prior to study enrolment; And must be non-lactation; Male patients who are not surgically sterilized or of reproductive age need to agree to use a medically approved method of contraception with their spouse for the duration of the study treatment period and for three months after the end of the study treatment period 10. Patients volunteered to participate in this study with good compliance and cooperated with multiple blood sample collection and follow-up
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Biomarkers associated with immune efficacy | up to 2 years | According to the biomarker detection before and after chemoradiotherapy to identify biomarkers related to the immune microenvironment, including the expression levels of NK cells, T cells, B cells and other immune cells reflected by PBMC, as well as the expression levels of ctDNA |
| Optimal time for immunotherapy | up to 2 years | Changes in the expression levels of ctDNA and PBMC immune cells before and after chemoradiotherapy to find the optimal time point for immunotherapy |
