In this setting, a standard lung cancer diagnostic biopsy workup includes standard hematoxylin and eosin (H&E) sections, PDL1 immunohistochemistry (IHC), diagnostic IHC (for example, TTF-1, p40 and so on), ALK fusion IHC, rapid EGFR testing and comprehensive genomic sequencing. This evidence concerns the gene EGFR and lung carcinoma.
