Supporting the above dataset and cell line results, immunofluorescence staining of the FFPE tumor tissues from EGFR‐mutant (n = 36) and EGFR‐WT (n = 16) NSCLC patients from Shandong Cancer Hospital also showed profoundly increased CD73 protein expression in EGFR‐mutant tissues (Figure 4e). This evidence concerns the gene NT5E and non-small cell lung carcinoma.
