Fig. 5

Kaplan-Meier curves show recurrence-free survival (RFS) rates in 122 patients with locally advanced breast cancer receiving neoadjuvant chemotherapy (NAC). a Graph shows RFS according to clinical T stage. Blue line = patients with tumors with higher clinical T stage (T4) (n = 35), green line = patients with tumors with lower clinical T stage (T1–3) (n = 87) (P < .001). b Graph shows RFS according to strain ratio (SR) on pre-NAC SE images. Blue line = patients with tumors with higher SR (≥ 12.9) (n = 47), green line = patients with tumors with lower SR (<12.9) (n = 75) (P < .001). c Graph shows RFS according to area ratio (AR) on pr-NAC SE images. Blue line = patients with tumors with higher AR (≥ 117.5) (n = 37), green line = patients with tumors with lower AR (<117.5) (n = 85) (P < .001)
