Kaplan–Meier curves for 5–10 years late DR rate according to Ki-67 LI in the CTS5 low-risk group. Late DR rate in patients with high Ki-67 LI was higher than that in the patients with low ki-67 LI in the low CTS5 group (log-rank P = .001). CTS5, Clinical Treatment Score post-5 years; DR, distant recurrence; LI, labelling index.
