The use of circulating tumor DNA (ctDNA) as a noninvasive test for breast cancer monitoring throughout the course of the disease
The concentrations of the cell free DNA (cfDNA) and somatic mutations in circulating tumor DNA (ctDNA) in serial samples correlate with the number of days of the progression-free period and with the overall survival.
