Survival curves of patients with cervical cancer according to stromal CD8+ TIL density. (A) OS, (B) LC and (C) PFS curves of patients with high (n=28) or low (n=47) CD8+ TIL density in pre-RT samples. (D) OS, (E) LC and (F) PFS curves of patients with high (n=38) or low (n=37) CD8+ TIL density in post-10 Gy samples. TIL, tumor-infiltrating lymphocyte; RT, radiotherapy; OS, overall survival; LC, locoregional control; PFS, progression-free survival; ROC, receiver operating characteristic.
