Circulating tumor cells provide genomic snapshot of breast cancer — ScienceDaily
“Counting the number of circulating tumor cells (CTCs) can tell us whether a patient’s cancer is aggressive, or whether it is stable and responding to therapy,” says the article’s first author Sandra V. Fernandez, Ph.D., assistant professor of Medical Oncology at Thomas Jefferson University. “Our work suggests that these cancer cells in the blood also accurately reflect the genetic status of the parent tumor or its metastases, potentially giving us a new and easy to source of genomic information to guide treatment.” First discovered for their diagnostic potential in 2004, circulating tumor cells are beginning to be used in the clinic to help guide treatment decisions and track a patient’s progress as the cancer progresses. …
