New technology to tackle treatment-resistant cancers

Free-flowing cancer cells have been mapped with unprecedented accuracy in the bloodstream of patients with prostate, breast and pancreatic cancer, using a brand new approach, in an attempt to assess and control the disease as it spreads in real time through the body, and solve the problem of predicting response and resistance to therapies. In comparison to a previous generation of systems, the researchers state their test showed a significantly greater number of high-definition circulating tumour cells (HD-CTCs), in a higher proportion of patients, by using a computing-intensive method that enables them to look at millions of normal cells and find the rare cancer cells among them.
