US researchers have found a new method that may help in monitoring cancer from blood tests more easily and accurately.
The study, led by researchers from Weill Cornell Medicine and the New York Genome Center, in the US, showed that the method may be useful for monitoring disease status in patients following treatment.
The method, based on whole-genome sequencing of DNA, also represents an important step toward the goal of routine blood test-based screening for early cancer detection.
"We're now entering an era of low-cost DNA sequencing, and in this study, we took advantage of that to apply whole-genome sequencing techniques that in the past would have been considered wildly impractical," said Dr. Dan Landau, Professor of Medicine, at Weill Cornell Medicine.
