Fig. 1: Current and future applications of ctDNA testing in metastatic breast cancer.
From: Circulating tumor DNA validity and potential uses in metastatic breast cancer

The figure summarizes different clinical situations in which ctDNA is currently being exploited or might be exploited in the near future for the treatment of metastatic breast cancer: a treatment selection; b treatment switch; c detection of emerging resistance mechanisms; d prediction of complex phenotypes; e integration of ctDNA dynamics with imaging response criteria.
