Range of stromal tumor-infiltrating lymphocyte (TIL) levels in all 12 cases. Each case exhibited different levels of TILs as follows: case 1, all 1%; case 2, 1 to 5%; case 3, 5 to 10%; case 4, 1 to 20%; case 5, 1 to 10%; case 6, 1 to 5%; case 7, 10 to 30%; case 8, 20 to 30%; case 9, 1 to 30%; case 10, 10 to 25%; case 11, 2 to 40%; case 12, 10 to 30%. Cases 1 to 6 are included in the CR group, and cases 7 to 12 are included in the CS group. Compared to the CR group, the CS group generally showed higher TIL levels. (CR: chemoresistant, CS: chemosensitive)
