Consensus on the diagnosis and treatment of unresectable stage III driver gene-positive non-small cell lung cancer.

Unresectable stage III non-small cell lung cancer (NSCLC) exhibits substantial heterogeneity and complexity. The landmark LAURA and POLESTAR studies have established a standard therapeutic model involving targeted consolidation therapy with osimertinib or aumolertinib after definitive chemoradiotherapy for NSCLC patients harboring EGFR-sensitive mutations. However, treatment strategies for patients with other driver gene mutations (e.g., ALK fusions, ROS1 rearrangement) still lack robust support from high-level evidence-based medical study. To enhance the standardization of diagnosis and treatment for unresectable stage III driver-positive NSCLC patients, the Radiotherapy Committee of the Chinese Society of Clinical Oncology convened an expert working group. This group identified common clinical practice issues and conducted an in-depth, problem-oriented analysis of domestic and international guidelines alongside evidence-based medical data. Through multiple rounds of comprehensive discussion and expert voting, this consensus was jointly developed. It provides evidence-based recommendations addressing frequently encountered clinical questions regarding unresectable stage III driver-positive NSCLC, aiming to serve as a key reference for clinical practice.
