This finding is mirrored in recently published data from phase 1 of the Blueprint Project, which explored the analytical and clinical comparability of four PD-L1 IHC tests used in clinical trials (Dako 22C3, Dako 28–8, Roche SP142, and Roche SP263) and found comparable results across the tests when applied to assess TC staining in NSCLC, although the test SP142 resulted in fewer stained TCs overall (phase 2 of this project is now underway and will seek to validate these findings and also provide data on a fifth assay developed by Dako that uses the antibody 73–10). Here, CD274 is linked to non-small cell lung carcinoma.
