However, results showed positive, but variable correlations between quantification methods in each tumor region, with weak correlations between CD3 density (tumoral and marginal CD3 positive T cells: R = 0.35 and R = 0.14, respectively) and moderate to strong correlations in CD8 density (tumoral and marginal CD8 positive T cells: R = 0.45 and R = 0.69, respectively; Figure 3). This evidence concerns the gene CD8A and neoplasm.
