Study Overview
Brief Summary
The goal of this clinical trial is to learn about in describe participant population. The main questions it aims to answer are:
the outcomes of the efficacy (ORR) and safety (adverse events, including irAEs, AE, SAEs, and laboratory indicators) of continued immunotherapy in patients with immune-resistant IIIc/IV metastatic NSCLC treated with immune-induced radiotherapy (SBRT).
Participants will be asked to accept the treatment of ICIs regimen and SBRT plan as follows:
ICIs regimen: tislelizumab 200mg every 3 weeks, the first dose was given 7 days after the last SBRT treatment, then the first day of each cycle, 21 days as a cycle until disease progression.
SBRT plan: The radiation dose and fractionation of SBRT should be evaluated according to the size and location of the tumor.
