In this Tech Blast episode, our Digital Editor Annie Coulson talks with Carlo Messina, Senior Director for Oncology in Global Development and Medical Affairs at Roche (Basel, Switzerland), about the use of comprehensive genomic profiling (CGP) in cancer research. CGP can obtain more information about a tumor from a smaller biospecimen compared with other genomic profiling techniques and gives oncologists more tools for treating patients. Carlo talks about the applications of CGP, including detecting genomic aberrations in the bloodstream, and the future of this technique.
