Consistent with these studies, we found smaller size, GGO, bronchiectasis, lymphadenopathy, obstructive pneumonia and absence of emphysema, and fibrosis were more likely to be associated with tumors with EGFR mutations, despite insignificant difference in density, bronchiectasis, lymphadenopathy, and obstructive pneumonia. This evidence concerns the gene EGFR and bronchiectasis.
