Kaplan Meier estimates according to the presence of persistent disseminated tumor cells in bone marrow after surgery. Kaplan-Meier estimates of systemic recurrence-free survival (A), and breast-cancer specific survival (B) according to positive (nā€‰=ā€‰23) and negative (nā€‰=ā€‰131) persistent disseminated tumor cell (DTC) status in bone marrow as detected three weeks and/or six months after surgery. P-values were calculated by the log-rank test. The numbers of patients at risk are indicated below each plot.
