Analysis of the expression levels of common immune checkpoints (PD1 and PD‐L1 in our study) and lung cancer driver genes (ALK, EGFR, ROS1, and MET in our study) between two clusters revealed significant differences in PD1, PD‐L1, and MET gene expression (Figure 6D–F). The gene discussed is PDCD1; the disease is lung carcinoma.
