Lesion-directed therapies and monitoring tumor evolution using liquid biopsies

Mariangela Russo, Alberto Bardelli

Research output: Contribution to journalArticlepeer-review


Precision oncology relies on targeted drugs, such as kinase inhibitors, that are presently administered based on molecular profiles obtained from surgical or bioptic tissue samples. The inherent ability of human tumors to molecularly evolve in response to drug pressures represents a daunting diagnostic challenge. Circulating freeDNA(cfDNA) released from primary and metastatic lesions can be used to draw molecular maps that can be continuously updated to match each tumor’s evolution. We will present evidence that liquid biopsies can effectively interrogate how targeted therapies drive lesion-specific drug-resistance mechanisms. The impact of drug-induced molecular heterogeneity on subsequent lines of treatment will also be discussed.
