Association of FOXP3+ TIL with patient survival. (A) Representative immunohistochemical staining of FOXP3 (brown nuclei), with examples of intraepithelial (arrowhead) and stromal (arrows) FOXP3+ TIL. Original magnification, × 200. (B) Box plots representing FOXP3+ TIL levels among tumour epithelia and stroma. (C) Distribution of FOXP3+ TIL in cases with (n=93) or without (n=82) disease recurrence at final follow-up. (D) Association of FOXP3+ TIL with RFS in the training, validation, and combined cohorts (FOXP3 high, n=92; FOXP3 low, n=83).
