Computed Tomography Features of Lung Adenocarcinomas With Programmed Death Ligand 1 Expression

PD-L1+ adenocarcinoma cases showed convergence and cavitation more frequently than did PD-L1− cases. In contrast, surrounding GGO and air bronchogram were observed less frequently in PD-L1+ cases than in PD-L1− cases. These results will prove helpful in identifying PD-L1-expressing adenocarcinoma by CT before immunotherapy.
