Fig. 2From: Effect of neoadjuvant chemotherapy on tumor-infiltrating lymphocytes and PD-L1 expression in breast cancer and its clinical significanceSurvival analysis of patients with residual disease following post-neoadjuvant treatment based on ΔTILs and PD-L1 expression. a Five-year recurrence-free survival (RFS) Kaplan–Meier curve of stromal TIL change (increase or decrease) following neoadjuvant treatment. b Five-year overall survival (OS) Kaplan–Meier curve of stromal TIL change (increase or decrease) following neoadjuvant treatment. c Five-year RFS Kaplan–Meier curve of PD-L1 status (positive or negative) in post-neoadjuvant cases. Positivity based on the visual cutoff of 500 AQUA method units. d Five-year OS Kaplan–Meier curve of PD-L1 status (positive or negative) in post-neoadjuvant cases.
