NSCLC is considered to be a heterogeneous disease, both in clinical presentation and genomic composition.20–24 In this study, we found that the rates of larger tumors, mixed GGOs with a CTR >0.5, IAC, pathologic stage IA2–IB, and EGFR mutations were significantly higher in older patients than in younger patients. Here, EGFR is linked to non-small cell lung carcinoma.
