CD274 and neoplasm: Quantification of tumor‐infiltrating lymphocytes (TILs), macrophages, and tertiary lymphoid structures (TLSs), together with the precise assessment of essential immune markers (e.g., PD‐L1, CD8, or CD4 cells) and their distribution in relation to the neoplastic cell compartments, can be attained with remarkably high levels of accuracy and reproducibility.
