Improvement enables ‘liquid biopsies’ for metastatic melanoma
Researchers at UCLA report that they have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients’ tumors and circulate in the blood. With the improvements to their device, which uses a Velcro-like nanoscale technology, they can now detect and isolate single cancer cells from patient blood samples for analysis.
Circulating tumor cells, or CTCs, play a crucial role in cancer metastasis, spreading from tumors to other parts of the body, where they form new tumors. When these cells are isolated from the blood early on, they can provide doctors with critical information about the type of cancer a patient has, the characteristics of the individual cancer and the potential progression of the disease. Doctors can also tell from these cells how to tailor a personalized treatment to a specific patient. (more…)
