Probability of relapse-free survival. Kaplan-Meier survival estimates of probabilities of relpase-free survival according to circulating tumor cells in operable breast cancer. (A) Probability of relapse-free survival in patients with CTC count ≧1 (Hazard ratio 2.72; 95% CI 1.57 – 4.72; logrank P < 0.001). (B) Probability of relapse-free survival in patients with CTC count ≧2 (Hazard ratio 3.12; 95% CI 1.52 – 6.41; logrank P = 0.001). (C) Probability of relapse-free survival in patients with CTC count ≥ 3 (Hazard ratio 3.97; 95% CI 1.79 – 8.84; logrank P < 0.001).
