Figure 1: Distribution of stromal tumor-infiltrating lymphocytes according to percentage (a) small stromal area between tumoral nests. Pay attention to small number of lymphocytes in this stroma. When you accept the stromal area as 100% the percentage of area occupied by lymphocytes as accepted as stromal tumor-infiltrating lymphocytes. It is %5 in figure a (b) Large stromal area between tumoral nests. This stromal area is occupied by more lymphocytes than the figure a, it is accepted as 40%
