Survival analysis of metastatic HER2+ breast cancer in the presence of low or high NK-cell (CD56) or macrophage (CD68) infiltration. Kaplan-Meier estimates illustrate the association of NK-cells (upper row) or macrophages (lower row) with survival in the invasive margin (IM) and in the center of the tumour (CT). Cutoff values for CD56 IM, CD56 CT, CD68 IM and CD68 CT (17, 12, 646 and 647 cells/mm2) were set using ROC analysis.
