Overview
Brief Summary
This study aims to evaluate the efficacy and safety of SBRT combined with Puterizumab immunotherapy for non-small cell lung cancer with pulmonary metastases, and to determine the correlation between MRD and treatment efficacy. Through single-cell sequencing and spatial transcriptome information analysis, the underlying mechanisms will be analyzed to provide a basis for improving the new precision treatment methods for tumor immunotherapy resistance.

Outcomes
Primary Outcomes
tumor response rate
Time Frame: From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.
The tumor response rate will evaluate the local control of lung metastases,referring to the evaluation criteria for solid tumor efficacy RECIST 1.1
Secondary Outcomes
- overall survival(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.)
- RTOG acute radiation injury grading(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted during the entire SBRT process and monthly after SBRT for up to 12 months.)
- QLQ-30 score(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.)
- Lymphocyte subpopulation analysis(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.)
- Minor Residual Lesions(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.)
- progression-free survival(From the date of enrollment until the first record of tumor progression or any cause of death (whichever comes first), evaluations will be conducted 3 weeks and every 3 months after SBRT for up to 48 months.)
