Liquid Biopsy

Previous Page   Next Page


An advantage of liquid biopsies is that it is a minimally invasive technique [1, 2]. It may also be used to detect a range of gene fusions (ALK, RET, ROS and NTRK1 gene fusions) from plasma, serum, circulating tumour cells, platelets and exosomes [1]. In addition, liquid biopsies can be performed over time during treatment and therefore can be used more easily than tissue biopsy for detecting molecular alterations arising during tumour evolution and those driving acquired resistance.
