Radiographically prior to surgical resection, all lepidic adenocarcinoma GGO specimens with high CEACAM5 expression (n=5) started as radiographic non-solid GGO and then actively developed a new radiographic solid component compared to only 46% of lepidic adenocarcinoma GGO with lower CEACAM5 expression, although this association did not reach statistical significance (100% vs. 46%, P=0.10) ( Table 1 ).

The sentences
• Exploratory observation showed high CEACAM5 expression (H-score ≥100) in semi-solid, lepidic lesions may track with radiographic evolution (including emergence of a new radiographic solid component and higher PanCK+ tumor cell composition), suggesting a possible trend with invasiveness in otherwise radiographically indolent-appearing lesions.
