Fig. 3From: Immune microenvironment in ductal carcinoma in situ: a comparison with invasive carcinoma of the breastKaplan-Meier survival curves stratified by immune cell subset infiltration and their ratio in pure DCIS. High level of FOXP3+ tumor-infiltrating lymphocyte (TIL) infiltration (a), the presence of PD-L1+ immune cells (b), high FOXP3+/CD8+ TIL ratio (c), and high FOXP3+/CD4+ TIL ratio (d) are associated with decreased recurrence-free survivalBack to article page
