MRD testing in early stage breast cancer. A-B) Kaplan-Meier curves showing distant recurrence-free survival for patients treated for early stage breast cancer and in whom MRD was detected or not at the post-op and year 1 (Y1) time points. Post-op and Y1 blood samples were drawn at a median of 3.6 months (0.23 – 8.43) and 14.3 months (6.77 – 21.70) after surgery respectively. C) Comparison of patients with distant recurrence in which MRD was detected or not at the post-op or Y1 time points. D) Timelines for patients with distant recurrence that were detected at post-op or Y1 time points. End points represent distant recurrence.
