Figure 2. Quantification of CTCs from 48 patients with metastatic prostate cancer using the CSV and CellSearch method.

Figure 2

Two blood samples from each patient were obtained and analyzed using both the methods. Patients were classified as having progressive or stable disease based on clinical evaluations. CTC counts were plotted per 7.5 mL of blood. Dashed line indicates a threshold of 5CTCs/7.5 mL. (A) CTC enumeration in patients with responding/stable disease using both methods. (B) CTC enumeration in patients with non-responding/progressive disease using both methods. The data show that the CSV method is able to distinguish the progressive disease population with a higher sensitivity and specificity than that of the CellSearch method.
