Real-World Immuno-Radiotherapy for Advanced NSCLC

The PACIFIC study has established radiotherapy combined with immune checkpoint inhibitors (iRT) as the primary treatment modality for unresectable, locally advanced non-small-cell lung cancer (NSCLC). Simultaneously, the KEYNOTE-001 study provided evidence supporting the efficacy of iRT in patients with metastatic and progressive NSCLC. However, most available evidence comes from interventional clinical trials, where participants are rigorously selected and required to adhere strictly to protocol-defined interventions. This creates a significant gap in real-world data, which is essential to further validate the survival benefits of iRT in advanced NSCLC. Furthermore, clinical trials evaluating concurrent iRT in NSCLC have largely yielded negative or inconclusive results, highlighting the need for clarity on the optimal combination strategy for iRT. To address these gaps, researchers will conduct a territory-wide real-world cohort study. The objective of this study is to validate the survival benefits of iRT in patients with advanced NSCLC and to identify the optimal sequential strategy for iRT.
