Objectives
Narrative objectives1
This study aims to explore the utility of circulating tumor DNA (ctDNA) as a biomarker for predicting pathological response preoperatively and for predicting recurrence, using previously collected blood samples from participants enrolled in the Phase II trial titled "A Phase II Study of Quadruple-Modality Therapy Incorporating Induction Chemoradiotherapy Plus Perioperative Immunotherapy for Resectable Discrete N2 Stage IIIA-B Non-Small Cell Lung Cancer" (WJOG12119L).
