Figure 1From: Comparative evaluation of cell-free tumor DNA in blood and disseminated tumor cells in bone marrow of patients with primary breast cancerHigh DNA levels significantly associate with lobular breast cancer. The box plot shows the comparison of serum DNA concentrations (a) in patients with ductal (n = 60), lobular (n = 10) and other (n = 10) breast tumors, and (b) in patients with disseminated tumor cells (DTC)-negative and DTC-positive bone marrow (BM) status. *Statistical significance according to the Mann and Whitney-U test for the non-parametric comparison of two independent variables.Back to article page
