Figure Lengend Snippet: Flow chart of the schematic overview of the current study design for the genome-wide copy number analysis of CTCs of BCLM. CTCs, circulating tumor cells; BCLM, breast cancer liver metastasis; MLBACs, multiple annealing and looping based amplification cycles; CNVs, copy number variations; PET/CT, positron emission tomography/computed tomography.

Article Snippet: CTCs from 7.5 ml blood sample were captured with the CellSearch Circulating Tumor Cell Kit (cat. no. K062013; Veridex, LLC) for 1 h at room temperature.

Figure Lengend Snippet: Analysis of CTCs in different patient samples. (A) Comparison of the CTC count between newly diagnosed liver metastases (n=23) and recurrent liver metastases (n=20) in a 7.5 ml blood sample of BCLM patients (n=43). In general, higher percentages of CTCs were observed in newly diagnosed BCLM patients (mean CTCs in newly diagnosed metastases 38.30 vs. 25.50 in recurrent metastases). (B) Linear logistic regression of CTC detection. Average (black line) CTC recovery was calculated by using the linear logistic regression from 43 BCLM patients. The cut-off levels (10 CTCs for expected and 5 CTCs for CellSearch per sample) are indicated by the dashed lines. *P<0.05. CTCs, circulating tumor cells; BCLM, breast cancer liver metastasis.

Figure Lengend Snippet: Gallery of fluorescent immunostaining of CTCs, EPCs and leukocytes (WBCs) from patients with BCLM. Cells were stained by anti-CD45-APC antibody, 4′,6-diamidino-2-phenylindole (DAPI, nuclear staining; pink color), anti-CK8-PE (green color). The CTC sample is characterized by a CD45 − /Nucleus + /CK8 + of a diameter <8 µm, while CD45 + /Nucleus + /CK8 − are identified as WBCs. Cells that stain CD45 − /Nucleus + /CK8 + are identified as EPCs with a diameter <8 µm (magnification 200 µm). BCLM, breast cancer liver metastasis; CTCs, circulating tumor cells; CK, cytokeratin; EPCs, epithelial cells; WBCs, white blood cells.
