Neoantigen-loaded DC Vaccine, PD-1 Inhibitor, and Radiotherapy for Advanced NSCLC Progressed After Second-line Treatment

In this study, the investigators provide a combined treatment of personalized tumor neoantigen-loaded dendritic cell (DC) vaccine, PD-1 Inhibitor, and radiotherapy to patients with advanced non-small cell lung cancer (NSCLC) progressed after second-line treatment. The investigators observe the objective response rate (ORR), disease control rate (DCR), adverse event (AE), serious adverse event (SAE), progression-free survival (PFS), and overall survival (OS) , aiming to evaluate the effectiveness and safety of the treatment.
