Case management funds breast cancer screening and diagnostic services for low-income women

Currently there is only one standardized and validated test approved by the U.S. Food and Drug Administration for the detection of CTC's, called the CellSearchTM system. CellSearch is a simple blood test that captures and assesses CTC's to determine the prognosis of patients with metastatic breast, colorectal, or prostate cancer at any time. This test, however, is only able to count CTC's and therefore additional technologies are being explored to capture more cells, different populations of the cells, and the gene expression patterns of the cells.
"It's important for us to look at all of these technologies in a more critical way to see which technologies are best at distinguishing between cells that have simply been shed by the tumor and those that are, instead demonstrating more aggressive," says Cristofanilli.
Using technologies that complement one another may also help improve the process of detecting these cells and design more personalized therapies. "For example, with inflammatory breast cancer we know that one technology alone will not help in detecting these cells," says Cristofanilli. "This doesn't mean they aren't there, it just means we aren't able to see them. It's like using a camera-by using full color, rather than black and white, you're able to see more distinct details."
