Circulating tumor DNA (ctDNA) is a revolutionary tool in the detection and monitoring of cancer: a minimally invasive, highly sensitive approach to analysing tumor-specific DNA in the bloodstream. Therefore, it is of interest to explore the current and evolving landscape of cancer genomics as precision tools in quantifying tumor dynamics. Thus, the role of ctDNA in tracking minimum residual disease, relapse, recurrence and the tailoring of therapeutic strategies for effective management of tumours is reviewed.
Keywords: cancer; ctDNA; genomics; predictive marker; tumor specific DNA.
