Probability of overall survival. Kaplan-Meier survival estimates of probabilities of overall survival according to circulating tumor cells in operable breast cancer. (A) Probability of overall survival in patients with CTC count ≧ 1 (Hazard ratio 2.29; 95% CI 1.12 – 4.67; logrank P = 0.02). (B) Probability of overall survival in patients with CTC count ≧ 1 (Hazard ratio 2.78; 95% CI 1.07 – 7.25; logrank P = 0.03). (C) Probability of overall survival in patients with CTC count ≧ 1 (Hazard ratio 4.88; 95% CI 1.87 – 12.73; logrank P < 0.001).
