Figure 5. Kaplan Meier survival estimates based on CD8+ tumor infiltrating lymphocytes (TILs) stratified on FAS expression in both ER-negative and ER-positive tumors.

In patients with ER-negative tumors with high FAS expression, the high presence of CD8-positive is prognostic for a significantly higher survival A. This prognostic effect is not observed in ER-negative tumors with low FAS expression B. nor in ER-positive tumors C, D. P-values represent log-rank survival test.
