For a better understanding, the cell phenotyping analysis was applied in tumor cells using the combination of key biomarkers, such as PD-L1 and Ki67, and expressed as a percentage of relative abundance within a selected region (Table 2); the counted objects allowed to express it as an objective score and was able to count less than 1% of a specific cell phenotype within the total scanned area. The gene discussed is MKI67; the disease is neoplasm.
