Third-generation EGFR-TKI Treatment in Metastatic EGFR-mutant NSCLC

The goal of this observational study is to explore the feasibility of stereotactic radiotherapy (SRT) as consolidation therapy for patients with advanced non-small-cell lung cancer who were treated with third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). The investigators plan to explore the time to achieve the best response after EGFR-TKI treatment, the characteristics of the distribution of lesions when the best response is achieved, the feasibility of SRT when the best response is achieved, and the phenotype of disease progression after EGFR-TKI resistance. In summary, this study will provide critical information for exploring the feasibility and optimal design of SRT as consolidation therapy for advanced NSCLC patients treated with third-generation EGFR-TKI, which will further promote the optimization of comprehensive treatment for EGFR-mutant advanced NSCLC.
