Figure 2From: Persistent tumor cells in bone marrow of non-metastatic breast cancer patients after primary surgery are associated with inferior outcome 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.Back to article page
