Figure A2.

Tumor-infiltrating lymphocytes and prevalence of PD-1 and PD-L1 expression on cells in melanoma metastases and the potential correlation with survival outcomes. Kaplan–Meier estimates of OS for intratumoral TIL (both CD3⁺ T cells and CD20⁺ B cells), CD3⁺ T cells and CD20⁺ B cells. Kaplan–Meier estimates of OS for peritumoral TIL (both CD3⁺ T cells and CD20⁺ B cells), CD3⁺ T cells and CD20⁺ B cells. No association was observed between immune subpopulations and OS. Kaplan–Meier estimates of OS for PD-L1⁺ and PD-1⁺ cells. No association was observed between cells expressing PD-1 or PD-L1 and OS. The arrow indicates the 3-year survival rate.
