NSCLC Stage IV Without EGFR/ALK Mutation
Conditions
Brief summary
This study aims to conduct a prospective, multicenter, umbrella clinical study to compare the abscopal effects of different radiotherapy fractionation patterns combined with Benmelstobart, and to explore an efficient and low-toxic treatment strategy for non-small cell lung cancer (NSCLC) with multiple metastases. The main objective is to explore and compare the control rates of abscopal lesions in NSCLC patients with multiple metastases when different radiotherapy fractionation patterns are combined with Benmelstobart.
Interventions
After 4 cycles of treatment with Benmelstobart combined with chemotherapy, if there is no progression, the patient will receive the treatment of 6-10Gy\*3-6F plus Benmelstobart.
For eligible subjects who have developed resistance to EGFR-TKI, after 4 cycles of treatment with Benmelstobart combined with Bevacizumab and chemotherapy, if there is no disease progression, they will receive the treatment of 6-10Gy \* 3-6 fractions plus Benmelstobart.
