Liquid biopsies hold expanded potential for more and more patients, thanks to improved techniques developed by researchers at the KI, the Broad Institute of MIT and Harvard, Dana-Farber Cancer Institute, and MGH Cancer Center. By analyzing fragments of DNA expelled by cancer cells into the bloodstream, the team, led by Love Lab alumnus Viktor Adalsteinsson, was able to detect and profile the mutations present in these tumors, presenting a viable alternative to traditional biopsy sequencing. As shown in Nature Communications, their non-invasive “cell-free” approach offers particular promise for understanding metastatic cancer progression and treatment response in advanced disease states. The team’s initial work was supported in part by a TRANSCEND grant through the KI's alliance with Janssen Pharmaceuticals, Inc.
