Official title
The Efficacy and Safety of Stereotactic Radiotherapy Combined With Puterizumab in Non Small Cell Lung Cancer With Intrapulmonary Metastasis:A Phase II Prospective Single Arm Clinical Study
Overview
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.
Interventions
- Radiation Stereotactic Body Radiation Therapy,SBRT
The enrolled subjects will receive SBRT treatment for lung metastases.The dose segmentation is 10Gy/f, with a total dose of 50Gy/5f, once every other day. - Drug Puterizumab
Within 7-14 days after SBRT, Puterizumab should be used (dosage: recommended dosage of 200mg, intravenous infusion, infusion time of 60 minutes (± 15 minutes), once every 3 weeks (Q3W), for 6-8 months or intolerable toxicity).
Primary outcome measures
- 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.]
Secondary outcome measures (6)
- Minor Residual Lesions [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.]
- progression-free survival [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.]
- overall survival [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.]
- RTOG acute radiation injury grading [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 during the entire SBRT process and monthly after SBRT for up to 12 months.]
- QLQ-30 score [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.]
- Lymphocyte subpopulation analysis [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.]
