Kaplan–Meier curves for progression-free survival in patients with metastatic breast cancer receiving trastuzumab–taxane. Differences between the survival times (days) for patients whose HER2/neu concentrations at 2 to 2 weeks of treatment had fallen to ≤ 77% of baseline values and those whose values had remained at >77% of baseline values (respective survival times 587 and 119 days).
