FOXP3 and neoplasm: Here, results indicated that the presence of CD8+ cells in the tumor compartment and FOXP3+ cells in the stromal compartment, were independent prognostic biomarkers for OS (p = 0.018 and p = 0.024, respectively), and CD8+ cell infiltration in the tumor compartment was an independent prognostic factor also for PFS (p = 0.004).
