This study aimed to evaluate the conversion rate to curative-intent treatment in patients with unresectable stage IIIB-IIIC non-small cell lung cancer (NSCLC) following induction therapy with PD-1 blockade combined with chemotherapy, and to assess progression-free survival (PFS) in these patients who underwent curative-intent treatment .
1. Patients voluntarily participate in this study and sign informed consent forms (including consent for relevant testing of collected biological samples).
1. Patients with NSCLC harboring driver mutations (e.g., EGFR, ALK, ROS1). 2. Prior treatment with anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-CTLA-4 therapies targeting T-cell co-stimulatory pathways.
