ctDNA as a cancer biomarker: A broad overview.

Critical reviews in oncology/hematology - 1 Nov 2020

Pessoa Luciana Santos, Heringer Manoela, Ferrer Valéria Pereira

Abstract excerpt

Circulating tumor DNA (ctDNA) in fluids has gained attention because ctDNA seems to identify tumor-specific abnormalities, which could be used for diagnosis, follow-up of treatment, and prognosis: the so-called liquid biopsy. Liquid biopsy is a minimally invasive approach and presents the sum of ctDNA from primary and secondary tumor sites. It has been possible not only to quantify the amount of ctDNA but also to...
