From: Persistent tumor cells in bone marrow of non-metastatic breast cancer patients after primary surgery are associated with inferior outcome

Figure 2

Kaplan Meier estimates according to the presence of disseminated tumor cells in bone marrow before and after surgery. Kaplan-Meier estimates of systemic recurrence-free survival (A), and breast-cancer specific survival (B) according to the presence of disseminated tumor cells (DTCs) in bone marrow (BM) only before surgery (DTC +/−, n = 13), only after surgery (DTC −/+, n = 15), both before and after surgery (DTC +/+, n = 8) and no presence of DTCs in BM (DTC −/−, n = 118). P-values were calculated by the log-rank test. The numbers of patients at risk are indicated below each plot.
